Window AC Leaking Water Outside

 All air conditioners drip water. It’s the nature of the beast. Condensation is a part of the refrigeration process of cooling down a room and dehumidifying it at the same time. An AC that is not producing condensation is not working properly.

Window AC Leaking water Outside.

When an air conditioner is working right, it is creating condensation as it cools down the air.

The condensation has to have a place to go and on a window AC that is either through a small drain hole located on a  back corner of the air conditioner or a drainage plug which drains outside.

The problem comes along when the water is not draining outside but inside the house.

Air conditioner leaking water inside

Window air conditioners are designed to drain out the rear of the unit, outside of the window.

If you your window AC
Is dripping water inside the house, then there can only be a handful of things that could possibly be.

Here is a few tips to help you diagnose your leaky AC situation.

1. Poor installation

The window air conditioner is meant to be installed, tilted slightly to the rear. That is simply so that the condensation will follow the path of the bottom of the air conditioner and drip out the back.

If the window AC is level or tilted towards the front of the unit, the moisture will follow the path of the bottom of the air conditioner to the front of the air conditioner.

Eventually it is going to find a place to leaked out into the inside of the house.

Easy fix- tilt the AC back. You can add a shim to the front if you need a way to keep it tilted.

2.  Not properly sealed.

If the warm air that is supposed to be expelled out the back begins to get into the house around the window AC. Condensation can begin to gather around the casing inside of a house.
Then just like a glass of ice water, it will begin to build up and eventually drip.

Easy fix #2. Weather strip around the AC.

3.  Drain is Completely clogged.

If your drain hole is completely clogged,   condensation water can build up to a point that it has to escape somewhere.

Easy fix #3. Clean out the drain hole. Take it even further and hose down the rear of the unit. Be sure to get between the grills to wash out anything that could be stopping up your drain hole.

Air conditioner leaking water insideWindow AC not dripping water

If you find yourself on the other end of the spectrum and your window AC is just not dripping any water, that is a definite red flag and you need to address it before it becomes an physical actual problem.

If you have a window AC that is not dripping water, then the drainage hole is clogged up. It’s important to get it unclogged because the water is going to have to find some place to go. And that could mean out the front into your home and onto your floor or carpet.

Refer to Fix #3

Is water leaking from the air conditioner dangerous?

The water leaking from the air conditioner is condensation which on its own would not be considered dangerous at all. But since it is following a path where there could be a build-up of mold and algae and other debris, drinking AC condensation water is probably not a good idea unless it is ran through a purifier.
But since it already is running out on the grass, it is probably safe to say that air conditioning condensation water is not dangerous for plants.

Is the water leaking from the window AC damaging?
Yes water leaking from your AC can cause damage to your walls and ceiling.
Not only can it damage your drywall it can become mold growing inside of your walls.

It’s safe to say that keeping an eye out for how your AC is draining is one of the easiest ways to avoid problems with your air conditioning.


Air Conditioner Not Blowing Cold Air?

Have you ever turned on your air conditioner and it’s just not blowing cold like you think it should?

Or maybe it starts off cold but turns warm only after a few minutes?

Did you know that most problems to do with the air conditioning are actually very easy to troubleshoot.

Of course there are things that can go wrong that can be out of the range of fixing or replacing yourself.

But when the AC is not blowing cold air, it’s usually only one of a few things.

Air conditioner not cold? Here’s a few simple reasons that could be.

1.  Clogged filter(s)

The first thing to check and by far the most common problem is the filter or filters being too dirty to allow for good airflow.

This is a problem that affects the cooling and the heating both in central heat and air systems.

Many a HVAC tech has been called to a residence to diagnose a air conditioning not getting cold problem only to find that the filters are clogged.

The first and easiest thing you can do to  get your air conditioning cooling again is to make sure that the filters are clean and the grill outside of the filters is dusted off and clean to.

2.  Thermostat settings

The thermostat on a home air conditioner has to settings that run the fan. One setting is the On sitting and the other is the auto mode setting.
The auto setting turn the fan on as the AC is cooling. The On setting runs the fan continuously even when the AC is not on.
Another reason that the AC may not be blowing cold air is that the cooling is off and the fan is set to On.

Not only will the air not be cool that is coming through the vents, it will probably be a little warm since most AC HVAC units are installed in the Attic.

Easy fix number 2. Make sure the thermostat is set to cool and Auto.

3.  Covered in debris.

The third thing to check is that the outdoor unit of your AC is clean and clear of debris. If you outside of the machine is covered in debris or weeds, the warm air that is supposed to expel from the unit outside will not be able to escape and will stay inside. Sending warm air through your vents and eventually overheating.

4.  Humidity

Humidity and air conditioners do not get along. when the humidity is High inside of the house you can feel like the air conditioner is not running at all.
Unfortunately the fix for this not something you can easily do with a little extra cleaning.
If the humidity is so hard that it is overpowering the air conditioner, a dehumidifier is a machine that can pull the moisture out of the air and allow your air conditioning to function normally again.
Some central heat and air units come with a setting called “dry mode”.
Dry mode is essentially a dehumidifier built into your air conditioner.

5.  Frozen up

Finally a problem that can be solved on your own to a certain extent is if the AC is freezing over.

The way the air conditioning cools down your home is it takes the warm air come inside of your home and lose it across refrigerated cooling coils. Then sends the air back into your home.

This is a problem that relates to the other steps in this short guide.

First you’re going to have to take a look at the unit outside to see if it’s frozen.
Sometimes it will be frozen enough that you can see it from the outside. Usually you’re going to have to take off the access panel and see if the copper coils are iced over.

If they are, you’re going to have to let it thaw out. You can run the fan without the AC and it will help thaw the unit little faster.

Air conditioner not coldWhy is your AC freezing over?

The Air conditioner relies on the are being able to flow freely across the cooling coils. If there is something obstructing we are in keeping it from moving across the coils easily, it can freeze over.

Easy fix. Change the filters, clean the grill outside of the filters, and clean any debris off of the outside of the outdoor part of a unit.

Another thing that relates to an air conditioner freezing up is humidity.
Too much humidity in the air can make the air flowing across the cooling coils to moist and produce ice as its going through.

Sorta easy fix. Run the dehumidifier or the AC on dry mode to reduce the humidity in the air and help keep the air conditioning from freezing over.

Window AC not blowing cold air

Window air conditioners work much the same way as a home AC but in a much smaller condensed package.

When the window AC is not blowing cold air, it usually boils down to one or two issues.

1.  The filter is clogged. When do you filter which is located on the face of the window AC gets clogged, the air conditioner will have a very hard time cooling off the room.

On most window AC the filter is very easy to pull out from the side or open the grill and pull it out that way.
A lot of very tiny dust particles can get lodged in the filter that are not easily seen with the naked eye. So be sure to take a stiff brush and brush it out very well before putting it back in.

If you wash the filter with water, be sure to let it dry good before putting it back in and running the AC because of the risk of mold taking root.

Window air conditioner blows cold then warm

If the window air conditioner gets too dirty the airflow begins to be an issue.

When the unit cannot get proper airflow it will start to shut down and go into a mode where it is running but not cooling.

Also the back of the air conditioner must be completely clear and not up against anything it will cause the hot-air that is supposed to expel out of the rear to not do so.

Taking apart a window air conditioner and cleaning it thoroughly, preferably by blowing it out rather than wiping, will do wonders to help restore your machine and get it blow cold air again.

And be sure to make sure that there is nothing obstructing the rear of the window AC that would keep the heat exiting like it should.

Window AC not blowing cold airWindow air conditioner keeps turning off.

A window AC usually has a reset button located where are the plug is. If the unit doesn’t come on at all, nine out of 10 times the reset button needs to be pressed before it will come on.

Window air conditioner panel not working

What if your window AC keeps going off and it is not tripping the breaker or the reset, there is a chance that your air conditioner panel is going out.

The thermostat panel on a window air conditioner is a fairly inexpensive part most dad’s will be able to fix on their own.

Luckily, there is a wide range of YouTube videos to take you through each step if needed.

Fan Mode on AC? – What, When, and Where?

Fan mode on AC is simply a setting on your air conditioner that keeps the blower fan running regardless of whether the cool air is on or not.

There are pros and cons for leaving it on.

One application for running the fan on the air conditioner continuously is the ability to keep the temperature even throughout the house even when the cooling is off.

Another application is the use of induct air purification. indoor air purifiers are installed directly into the plenum and ductwork of your central heat and air system. They require the AC fan mode to be left on continuously.

AC Fan Mode-  Should AC fan be on auto or on?

Being that the AC is one of the biggest energy hogs in the home, running the AC on auto, is usually the best choice because it keeps the utility bill down.

There are several reasons for this.

For one it takes extra energy to run the fan all the time, which means more power consumption.

Two, keeping the fan on continuously when the AC is not running evaporates the moisture that is normally condensed, and sends it back through the system.

The result is higher humidity inside of the house, which means that the AC has to work extra hard when it kicks on to counteract the effect of the humidity.

Running AC fan only

Running the AC fan alone without the air conditioner is a good way of evening out the temperature throughout a house but since the ductwork is typically in the Attic,

More than often means that you’re blowing hot air through the vents since the attic is the hottest room in the house and that’s the starting point for the air that is getting moved through the system.

So using the blower fan on an AC does not equate to using a regular fan.

but if you are using some type of air purification module inside of your ductwork then running the AC fan only is a perfectly good way of getting a whole-house effect of an air purifier.

Should the fan be on when the AC is on?

Yes. The fan on your AC will blow when the unit is set to cool. The fan is what helps distribute the cool air evenly throughout the house. Once the temperature inside the house reaches the desired input that you put into your thermostat, the cool air will stop.

And depending on whether your AC fan is on auto or on, the fan will either turn off with the AC or keep running. Auto on automatically shutts off when the air conditioner shuts off and “fan on” to keep the fan running when the air conditioner turns off.

Does running the fan on my air conditioner reduce humidity?

Running the fan on an air conditioner without the cool air turned on can actually have the opposite effect of reducing humidity.

Leaving the fan running when the AC is not running is a sure way to increase the moisture in the air because any moisture in the system will evaporate and distribute back through your house.

Humidity is actually reduced more when the AC is running on cool. And if your AC has a dry mode, it will reduce humidity further.

Does leaving the AC fan on waste electricity?

Though the AC fan has a couple of good points like keeping the temperature even throughout the house when the AC is not on, it does tend to be a waste of electricity otherwise.

Some systems with built-in air purification systems must have the fan on continuously to keep the air purifiers working efficiently. Sometimes you just can’t get out of paying.

Does fan mode bring in outside air?

Air conditioners rarely bring in air from the outside even when they’re on fan mode. The supply side of the air conditioner is inside the house.

That is one of the primary reasons that air conditioning is known to be a source of indoor air pollution. Because the same air is being distributed through the system and throughout the house.

If the air inside your AC is dirty, then the air inside your house is unhealthy too.

Why does the fan keep running on my air conditioner?

The easiest thing to check when your AC fan won’t stop running is whether or not the mode is set on Auto or On. If it is on, there you have it. Super easy fix.

Another easy check is the HVAC filters. If they get too dirty, then the air can’t flow through the system properly and the system will continue to run trying to reach the desired temperature set on the thermostat.

AC filters are a good place to start when the unit isn’t cooling right too.
There is no telling how much money has been spent on technicians only to find out the filters are clogged.

Those are the easy fixes.

If it is not one of those, then the problem is probably a little worse.
It could be a relay or the thermostat.
Those are fixes that are usually left to  professionals.


ac fan modeWhat does the fan setting on an air conditioner do?

The fan setting on an air conditioner gives you the ability to run the fan continuously or to have it go on and off automatically when the AC is cooling.

The auto fan mode is generally a little cheaper to run because it doesn’t use the extra power to keep it running all the time.
But there are times when using the fan without the AC cooling is needed.

An example is using in-duct air purifiers in your ductwork. In order for the air purifiers to be efficient, the fan on your AC needs to run all the time.

But running the fan on the AC is not the same as using a regular oscillating tower fan.

It will not do much to cool a room since the air that it is moving in most homes comes from the attic. and not from outside which is a common belief.

The Attic is the hottest area in the house so any are originating from there he was going to be warmer. Not a bad ideal in the winter.

AC Dehumidifier(Dry) Mode- What and When Do You Use It?

What is Dehumidifier (Dry) Mode in AC?

High Humidity is the number one cause of mildew and mold growth in the home.  It is also responsible for increased Allergy symptoms and can be a trigger for an Asthma attack. 

Dehumidifier mode, also called Dry Mode,  on an AC is the setting that turns on the dehumidifying function of an air conditioner to reduce excess humidity in the air.

When there is too much humidity in the air, the temperature can seem hotter than what it actually is.
Using the dehumidifier/ dry mode on the AC will help reduce the moisture in the air and restore comfortability back to your home.

What is the function of dry mode in AC?

Dry mode in an AC functions like a dehumidifier. Dehumidifiers and air conditioners are actually very similar in the way they work. They both drag air across a set of cooling coils that causes the air to condense.

AC Dehumidifier Dry ModeAir conditioner dry mode vs. dehumidifier

The difference is that air conditioners move the air across the cooling coils to cool off the air where is a dehumidifier moves the air across the cooling coils to condense the air but then reheats the air to repeat the process. 

Dry mode vs. cool mode

Dry mode on your AC is the air conditioning setting that turns on the dehumidification function of the AC to reduce the humidity in the air.

Cool mode is the setting that cools down the air. Cool mode is the most common setting on an AC. It is the mood of the air conditioner that cools down the room to the temperature that you set the thermostat to.

Air conditioner dehumidifier mode

Humidity, especially the excessive humidity that tends to hit in the hottest months can be a real enemy to your air conditioning.

When the relative humidity gets to a certain level, you can feel like the air conditioner is not even on.

And usually what happens is that you run to turn the thermostat down cooler.

But with so much moisture in the air and adding more power to the air conditioner, the results of turning the air conditioner thermostat down usually leads to the unit freezing over.

Then there is no cool air coming from it at all.

Another reason that humidity threatens your AC unit is that your system has to run on overdrive to keep up with the extra demand that the humidity places on it.

But you may be sitting on an air conditioner that has a function to help in those situations. And you might not have even known it.

The function I’m talking about is the air conditioner dehumidifier mode.

The air conditioner dehumidifier mode is usually represented by a raindrop symbol on the thermostat. It is also called the dry mode if you have an air conditioner with this function but it does not say dehumidifier.

what is dry mode in ac

Does an air conditioner dehumidify?

When your AC is in dehumidifier mode,
It turns off the cooling function and slows down the fan so that the air conditioning functions as a dehumidifier to reduce the moisture in the air.

Does air conditioning dry out the air?

By reducing the moisture in the air, you can regain comfortability without even having the cool mode running.

Not only will that save you money on energy, it will help save you in the long run by not overworking your air conditioning system.

Best temperature for dry mode

The best temperature to use dry mode is when the humidity is excessive but the actual temperature is not that hot.

The ideal of turning the AC on dry mode is to reduce the moisture level in the air and restore the comfortability of the area without using the cool air mode of the AC.

The function of Dry mode on an AC is to lower the humidity in the room so that the air feels cooler. It does not actually control or utilize the thermostat to achieve a designated temperature.

Dry mode vs. Cool mode power consumption

ACs are one of the biggest energy hogs in your house. Everyone knows how much the utility bill can skyrocket in the summer months because of the power that an air conditioning system uses.

The different modes on an air conditioning unit or not only to help provide you with the most comfort possible in terms of climate control but also in financial terms.

The cool mode on an air conditioner is easily the most expensive to run. And it is the setting that most people tend to use exclusively.

But there are different times when using the cool mode on an air conditioner is not only more expensive, it can’t get the job done as well.

Dry mode on an air conditioner can actually lower your energy bill provided the climate dictates it.

When the humidity is so high that it is overcoming the air conditioning,

Turning the AC dry mode will not only help reduce the humidity in the air and make the air feel more comfortable, it will turn off certain features on the air conditioner that are causing the energy bill to be more expensive.

When the dry mode is functioning, it turns down the cool air and it slows the fan way down.

Which means the power consumption of the air conditioner is way down.

In other words, less power, more money in your pocket.

Not only does humidity cause your air conditioner I do feel like it’s doing less than an adequate job, it also makes your air conditioner overcompensate to try to get the temperature in the room down to a comfortable level.

That means the power consumption in cool mode during times of excessive humidity will actually cost you more.

Air conditioner dry mode in winter.

The dry mode on an air conditioner, though it works like a dehumidifier to a certain point.
But at the end of the day they do not have the full function of a dehumidifier.

A dehumidifier compared to a air conditioner not only condenses the water to capture the humidity, it reheats the air that is released.

An air conditioner simply does not have this capacity.

Even most dehumidifiers call for the temperature to be at least 60 degrees.
Which makes them obsolete during the winter.

Using an air conditioning as a dehumidifier during the winter will not work for that intention, it will most likely cause damage to your unit.air conditioner dehumidifier mode


What is an Ionizing Air Conditioner?

Air conditioning is something most of us take for granted. But few of us realize how lucky we are to have air conditioning. Combining the ability to sanitize and clean the air in a room with the same system that delivers cool air only seams logical.

What is an Ionizing Air Conditioner?

An Ionizing Air Conditioner is a air conditioner with a built in ionizer.

The Ion or Anion mode on an AC reduces indoor air pollutants like germs and bacteria by emitting negative and positive ions into a room.

When the AC ionizer is in operation, Plasma ions ( ions with both polarities)
surround airborne contaminants like viruses and effectively damage the cells and make them inactive.

It is interesting that the anion symbol on an ion air cooler is a pine tree. This probably is a reference to fact that negative ions exist in abundance in the forest.

Negative ions are also known to be in abundance at beaches. Negative ions are found in their highest after a thunderstorm. Lightning is where they source from.

Plasma Air Conditioner

Plasma Air Conditioners use a unique ionizing method that more efficient than standard negative ion generators and do not create detectable ozone as a by-product. Also called Bi Polarization because the Anion Air Cooler emits both negative and positive ions. 

Though only a couple or few years ago, Ion air conditioners seemed like the new rage. Models like the Sharp Plasma Air Conditioner and LG Residential mini split with Plasma Mode had amazing features, yet didn’t become the great sellers you would think they might have.

Regardless whether your air conditioning is equipped with an Air Ionizer, Bi Polar Plasma air purifiers are still available as induct HVAC air purifiers.

Plasma Induct air purifiers are actually more efficient than a mini split with a built in Ionizer.

Induct air purifiers use the existing HVAC ductwork to create a whole house air purifier.

Since the air inside of the house is already being circulated through the central heat and air system, it makes sense to clean the via the system that is distributing it.

Additionally, the HVAC itself is one of the main sources of indoor air pollution in the first place.

Because of the climate of moisture and darkness inside of the air handler, mold has everything it needs to become a issue inside of your system.

And once the air kicks on, mold spores and bacteria existing inside the unit are then moved around through your entire home.

Induct air purifiers clean the air at the source of the pollution and distribute clean air throughout.

ion air conditionerDoesn’t that mean you have to leave the fan running for the air purifier to work?


There are expenses that come with come with leaving the fan running like an increased energy bill and more degradation through the filters since they are in use all the time.

But the cost between using a plasma ionizer in the HVAC compared to using HEPA filters in the HVAC is pretty small.

The reason is, central heat and air needs good airflow to work properly. HEPA filters are so dense that they tend to overworked the air conditioner.
Which leaves higher energy bills and a little lower life expectancy for the HVAC unit itself.

Another bonus to using induct ionizers is space that it goes any ozone created to dissipate without becoming an indoor air pollution problem itself.

Also stand-alone ionizers tend to make all the surfaces around the ion machine extra dusty.

The reason for that is that ions weigh more than dust. So when the ions that are emitted from the machine connect with the particulates in the air, they clump together and fall.

Grey Wall syndrome is a phrase that describes the dust that gathers on walls when an ionizer is present.

Induct ionization doesn’t have the same problem because the ionization process happens inside of the ductwork.

That doesn’t mean that it will not leave extra dust behind inside of the ductwork.

And unfortunately an ionizers in air purifiers do not filter dust so you will still be flipping the cost to have the ductwork cleaned out from time to time.

What Does Ozone Smell Like?

Should Ac Fan Be on Auto or On?

What is auto mode in AC?

Auto mode on the AC simply means that the fan on the air conditioner turns on automatically while the air conditioning is running. Once the room gets to temperature,  it then shuts off.

The ON position for the fan means that the fan will continuously run even when the air conditioner is not running.

Should Ac Fan Be on Auto or On?

Using the AC fan on Auto is considered the energy and money saving mode.

Here are a few reasons why:

Running fan on air conditioner continuously


  1. Increase Energy Bill
  2. Use More Filters
  3. Increase Relative Humidity
  4. Cool Air Leakage
  5. Increase Repairs

What is auto mode in AC1.  Increase the electricity bill.

By constantly running the fan you will bump up your energy bill.

2. Increased Filter Replacements

Continuously running the fan will called you to go through more filters because of the extra use.

3.  Increases the level of relative humidity.

When the AC is off, the dehumidifying function of the air conditioner is off to.
The moisture that would drain out while the fan is off doesn’t get a chance and is recirculated around the house with the fan on.
 Which means that the air conditioner has to work extra hard when it kicks back on to combat the extra humidity in the air.
That means a higher energy bill and more chances of service calls.

4.  Cool air leakage.

Air ducts or not foolproof and do have a fair amount of leaks. Keeping the fan running while the air conditioner is off can cause the cool air to leak out faster.

5. General repairs.

The fan motor running 24/7 will shorten the life of the motor. 

There are some advantages to leaving the fan on all the time.

  1.  The fan will help keep the temperature even throughout the house when the AC has turned off.
  2.   The HVAC central heat and air unit is actually a very efficient whole house air purifier when there is UV ionizers placed in the ductwork.

These in duct air purifiers require the air to move through the house regularly  work right.

Running AC fan only?

Having the fan on can help even out the temperature throughout the house by redistributing the air.

But, the AC fan doesn’t really cool down the house on its own. It is primarily used to circulate air through the ductwork and doesn’t have too much of a cooling fan effect otherwise.

The main reason you might want to keep the fan on the air conditioner running continuously is when you are using induct air purification which needs the fan to circulate the clean Air throughout the house.

Running AC fan only

Do Air Conditioners Purify Air?

Having an air conditioner is an indispensable part of living in today’s modern culture.

Can you imagine that the indoor air conditioner has only been around since the early 1900s?

Many of the architectural designs we admire, high ceilings for instance, came to be out of necessity define ways to cool off the air inside of the house.

But these days,  only a little over a hundred years later, many of us cannot stand to be outside in the summer separated from the cool air indoors.

But as building techniques have grown into highly sophisticated ways keeping our homes sealed up, we now have a different problem of our indoor air being polluted.

Breathing clean air is as fundamental a need as being able to cool down or heat up indoors.

It would be great if the same appliances and machines that cool and heat our air we’re also responsible for cleaning our air.
But is that even a possibility?

Do air conditioners purify air?

Air conditioners function mainly to cool off the air in a home but they do work slightly as an air purifier in two ways.

1. They filter the return air.
2. They reduce the humidity can facilitate mold growth and house dust mites.

Do I need an air purifier if I have ACDo I need an air purifier if I have AC?

Yes. Though your AC can help clean your air through the return vent and keeping the humidity down to a small extent, your typical indoor air quality is much worse then what the air conditioning is able to combat.

Though your AC does have a filter, the primary reason it is there is not to purify the air but to keep dust pollution from getting into your air conditioner.

And though you can purchase HEPA filters that capture much more air pollutants then the typical AC filter,

You have to remember that the AC requires a free flow of air to function properly. Using a dense filter like HEPA for your AC we’ll put a lot of strain on your machine and require much more energy to work.

And though air conditioning coils work much like a dehumidifier, relying on the air conditioner alone to reduce the humidity in the house during the hot summer months also causes the AC to work on overload. Which makes your bill higher and the efficiency what’s your air conditioner work lower.

The air conditioning function of your HVAC unit is also responsible for much of your bad indoor air.

What do I mean?..

The climate inside of your HVAC is moist and it is dark. And there can be actual standing water inside of the drip pan located by the condenser coils.

Standing water in a moist dark area is the ideal environment for mold to grow.

If you have mold inside of the duct work of your AC, then every time your unit cycles, it dispenses mold spores throughout your home via your duct work.

And then the same moldy air gets pulled into your return vents where the cycle starts over again.

Another problem your AC poses to the indoor air quality in your home is dust mites.

If your duct work is dirty, then you have a built-in home for dust mites.

Dust mites also flourish in humidity.

and how humidity is one of the main reasons the air conditioner is running Non-Stop in the summer.

A vicious cycle..

Long story short. Indoor air quality is not best left to an air conditioner to manage.

Air conditioner with air purifier?

With most combo type devices whether it be a humidifier / diffuser or air conditioning and air purifier all-in-one combo, the result is usually subpar.

Most of these machines do completely different jobs and shoving all the parts for both inside a box is not the best ideal.

The portable air conditioner with a built-in air purifier usually means one of two things:

1.  It contains a HEPA filter that can filter out smaller particles as the air is being pulled into the air conditioner.

2. Or the purifier itself is an ionizer

Using a HEPA filter in the slot where the normal AC filter goes will capture a little more of the airborne contaminants then the typical filter but it cannot do anywhere as much as having a dedicated filtering air purifier.

Plus the exchange of air that an air conditioner requires to work properly does not happen easily when the air filter is extra dense like a HEPA.

The result will be much like running the air conditioner with a dirty filter which limits its ability to cool dramatically.

A portable or window air conditioner with a built-in ionizer is a better idea but it doesn’t exactly make for all the components of a good air conditioner or a good air purifier.

The problem is is that ions have a very short life and they have a even shorter life when they are blown by a fan.

The air condition will have to be kept on it the lowest fan setting for the ionization to have a real effect on the room.


Ionizers inside of a HVAC air conditioning unit can be a much better idea.

Specifically ionizers that use photocatalytic oxidation or plasma.

Placing these air purifiers directly into the ductwork and the plenum of your HVAC can extremely limit the amount of mold and germs, as well as dust mites that are distributed by your AC and heat every time your air handler kicks on.

This is the best way that your air conditioning can actually be your air purifier and efficiently work as a air purifier and air conditioner.


Can your air conditioner purify air?

Yes your air conditioner does have some slight air-purifying function because it does contain a filter that captures dust pollution before it is pulled into the AC.

Also air conditioners have a dehumidifier effect that help reduce moisture in the air which can facilitate dust mites and mold spores.

But air conditioning is not an air purifier and does not have the capacity to manage indoor air quality or efficiently combat indoor air pollution.

Though there are a few portable air conditioner and air purifier combo available to the public, they are fundamentally flawed and do not cool or clean the air, either one efficiently.

But if your home is outfitted with central heat and air, the opportunity for you to have an air conditioner that efficiently cleans the air is available.

In duct air purifiers, specifically photocatalytic and plasma in-duct air purifiers can efficiently clean the air inside of your ductwork as well as clean the air that is returning to your unit to be redistributed.

Hopefully as time moves forward, this type of air purification will be built in to each central heat and air unit that is being installed.

We’ll see…


What Kind Of Mold Grows In Window Air Conditioners?

Window air conditioners rarely get moldy. When you find a window air conditioner has mold growing inside of it, it is almost always exclusively because of standing contaminated water.

What kind of mold grows in the window air conditioners.

The 4 most common mold types found in window air conditioners are:

  1. Fusarium
  2. Acremonium
  3. Alternaria
  4. Mucor

What kind of mold grows in the window air conditioners1.  Fusarium

The highest level of fusarium spores occur in the summer months and require wet circumstances. It can grow in stagnant water and in humidifier catch pans.

2.  Acremonium

Acremonium is commonly found in Hay and other dead plant material. It is also found in water damaged building materials and because it needs a very wet environment it also grows in the insulation around air conditioning.
It can easily get its start from cooling coils, standing water in drip pans, or humidifier water.

Acremonium often grows in combination with stachybotry chartarum. The dreaded black mold. Black mold requires extremely wet long-standing conditions.
It is considered one of the major components in sick building syndrome.

3. Alternaria

Alternaria is the most common form of mold found in building materials and is often found in water damaged or flooded areas as well as standing water in humidifiers.

4.  Mucor

Mucor is the chrysalis looking mold that gathers around the condensation on the windowsill of the air conditioner.

Each type of mold listed needs a steady supply of moisture in order to cultivate.
And also each of these types of molds can be found in drip pans or humidifier pans where there is standing water.

Finding the moisture supply and eliminating it is the way to get rid of any type of household mold.

What kind of mold grows in the window air conditionersWhy do window air conditioners get mold?

1. They have standing water inside the housing.

Standing water means contaminated water. A dark area with standing contaminated water are the perfect recipe for mold production.

Condensation from the air conditioner is meant a drip out of the air conditioner through the back.

How to prevent mold in a window AC unit?

If there is standing water It can only mean that there is something blocking the condensation water from leaving out the back of the air conditioner.

If that’s the case you’re going to have to take the air conditioner out, take the housing off and clean up any debris that is causing the air conditioner condensation not to drip out
of the air conditioner.

This includes getting the debris out of the inside of the air conditioner and anything on the outside that is causing the condensation water not to drip out or the back of the air conditioner.

Another point to make is that there is really no way for that kind of debris to get into the back of the air conditioner unless it is directly under a tree or some other type of rotting wood, branches, leaves, so forth that are able to work their way down into the filter slots on top and sides of the machine.

Cleaning around the air conditioner and making sure that it is not located in an area where anything can get in and stopped up the drip hole also has a part.

At this juncture, Since the air conditioner is already apart and you have identify the problem is being a stopped up drip hole,
Another thing you can do is drill a couple of new drip holes in the bottom of the air conditioner.

It is very easy to do and it will not do anything to diminish the performance of the air conditioner and it will only help keep the condensation from gathering inside the bottom of the machine.

Simply with at least a 3/8 inch drill bit, drill through the bottom of the air conditioning housing. This will add an additional opening in the bottom of the air conditioner for condensation to drip through.

2.  Putting the filters back in when they’re wet.

When the air conditioner doesn’t seem like it’s cooling very well, the first thing to do try used to remove the filter from the front of the machine pointing into the house,  and wash it.

When air can’t get through the filter, it can’t get into your house.

But when washing the filter with water it is important to remember to let the filter completely dry.

Putting the filter back in wet get you back to the fundamental ingredients of mold spore production. Water and darkness.

3.  Improper storage

If you are storing the air conditioner, remember to place it somewhere where it does not have a way to get water in it or cover it well with plastic wrap so that the insides cannot get wet.

Window air conditioners air made to keep mold out. And in fact air conditioning is usually one of the major factors in having dry air.

Dehumidifiers basically function the same way as a window air conditioner and are made for reducing moisture and humidity.

So if you have a problem with mold in your window air conditioner,

Swamp coolers with mold

Evaporative coolers or swamp coolers also have some of the same problems with mold production.

The only thing is that they require water to be circulating inside the machine to be able to blow cool air inside of the window.

A couple of reasons why your swamp cooler may be getting mold is:

1. Allowing the water to stand inside the housing when the unit is not in use.

The water supply continues to drip when it is turned off thereby supplying water to the swamp cooler that it’s turned off.

The main point in keeping mold from getting into the swamp cooler is to keep everything inside the cooler clean.

When you’re not using it, do not allow any standing water inside of the unit and make sure that the pads are dry. Make sure the water is turned off well and is not allowing for any drippage into the pads.

Storing the swamp cooler or getting it ready for winter is an important part of using an evaporative cooler and keeping it free of mold.

The machine must be completely drained and allowed to dry as well as the pads.

Completely disconnect the water ,and use a rain and snow proof cover to completely surround the unit so it stays dry.

Also don’t forget to put the drain plug back in, verman love to find a swamp cooler that hasn’t been put away properly to make their bed in. The drain plug is just the right size for mice and rats to make a front door.


Window air conditioners do not typically get mold because they are built to expel mold, but in some cases usually due to condensation not being able to exit the machine properly they can get a variety of molds including fusarium, acremonium, alternaria, and muscor.

Usually the answer is to figure out why the condensation water is gathering in the air conditioner and eliminate the blockage.

Why Does Air Conditioning Make Me Cough?

Why does air conditioning make me cough?

Coughing around an air conditioner is usually a symptom that your air conditioning unit is dirty.

For example, neglecting to change the AC filters will cause the debris and allergens caught in the dirty filter to circle around the house when the unit kicks on.

Dirty filters can also cause your unit to function poorly.

The first place to look when your air conditioner is not cooling or causing you to cough is the filters.

Some Reasons for Air Conditioning Sickness Symptoms

  • Dirty filter
  • Air conditioning drying air out
  • Mold in duct work
  • Dust and dust mites in duct work

h4>Air-Conditioning Cough Treatment?

Treating an AC cough is not about taking a pill or getting some rest, it is identifying what is in the air conditioner or the air conditioning ducts that is causing you do you have an allergic reaction.

why does air conditioning make me cough
Check the Filter

The easiest thing to check when you find yourself coughing or getting a dry or sore throat around an air conditioner is the filter.

This is a more common problem than you would think. There is no telling how much money has been spent hiring a HVAC tech only to find out that the filter hasn’t been changed and the unit is not heating or cooling. A cool hundred dollars down the drain for such an easy fix.

If the HVAC filter is not changed regularly then all the household allergens floating around the air, things like pet dander, pollen, dust mites, and just everyday dust are all stuck in your HVAC filter.

So basically every time the unit kicks on, it filters the air through a layer of allergens before it distributes back into your room.

Any one of these pollutants can present you with allergy symptoms like coughing, sore throat, sneezing, phlegm, etc.

Changing the dirty filter may not only alleviate an annoying cough when you’re around air conditioning,

You will also have identified a problem that will eventually cause your HVAC to work much less efficiently or even freeze up.

Not changing the filters or not using a filter will also provide a early death for your air handler.

AC Dry Air

The second reason your AC may be making you cough is that air conditioners dry out the air.

When there’s not enough humidity in the air you can experience a whole host of symptoms including coughing, sore throat, clogged nasal passages,etc

The easiest thing to do when there is not enough humidity in the air is turn on the humidifier.

If you’re not acquainted with what a humidifier is, it is a small appliance that you fill with water, which is slowly dispersed into the air as a mist.

Humidifiers are a low-cost item that can give you an enormous amount of relief from the health symptoms related to dry air.

In the South where I live, we keep cool mist humidifiers in every room during the winter.

If you don’t have a humidifier, there are some ways that you can add moisture to the air without one.

How do you humidify the air without a humidifier?

1.Place some open containers of water around the room or house.

This is an old trick that I remember seeing as a kid but back then I had no idea what the water was for.

My grandmother would keep mason jars with water in them, sitting around the house on shelves and whatnot.

Turns out she was simply adding some moisture to the air.

2. Plants

Plants require watering, so keeping house plants is also is a great way of adding moisture into the air. They will not only help add some humidity back into the air, they will also supply some much-needed oxygen back to the air that will also help you breathe.

Some species of plants also act like an air purifier and will help keep your air clear of allergens.

3. Another humidity remedy that I remember seeing as a kid was keeping a pot of boiling water on the stove.

Keeping a pot of water slowly boiling on the stove top will do a great deal to add humidity into the air will that having to purchase a humidifier.

Moldy AC

The third thing you can check when you have a air conditioner cough is whether or not your air conditioner has mold in it.
Unfortunately this is not as easy as changing your filter or turning on a humidifier.

Your air conditioner could be moldy because AC creates condensation when it is running, the inside of an HVAC system, being that it is dark and humid, is actually the perfect environment for mold to breed.

The easiest way to find out if you have a moldy AC is to examine the Vents and see if you can find any mold around them.

If you do then great, you’ve identified the problem.

But if you don’t then that doesn’t automatically mean that there is not mold in the system.

Since there’s no way to get inside the duct work without some kind of probing camera,

The second way to look for mold in your HVAC is to simply smell for it.

Mold and mildew you have a distinct smell that you will probably recognize as soon as you smell it.

Getting the mold out if the AC is a whole other issue.

This is where you start talking about spending money to fix the problem.

The first thing, of course, is you’re going to have to call in an HVAC tech.

He will clean your duct work and supply you with a new filter and will probably suggest that you purchase a induct air purifier.

In duct air purifiers work by:

a. targeting ultraviolet light on the source of the mold which is the coils in the drip pans

b. PCO or plasma ionic air purifiers.

These purifiers are placed in your in duct system and run continuously in the background to ensure that the air inside of your unit is clean and that you are getting clean air delivered into your house via your HVAC duct work system.

Dirty and dusty duct work.

The fourth reason you may have developed a cough when you around air conditioning is that the duct work is just plain dusty.

Like stated before, the inside of the HVAC is going to be humid by nature because of the fact that air conditioning creates condensation when it is working.

What do you have when you combine dust and humidity?

Dust mites.

Dust mites thrive in humidity.

Dust mites are also a major source of indoor allergy problems.

Just like mold, dust mites also can exasperate asthma causing symptoms like tightening in the chest and wheezing.

If the duct work is extra dirty, then there is no other recourse other than calling your neighborhood HVAC tech.

Another one of those bills that you’re going to be shocked at the price when you realize that it could have been avoided simply making sure you’re using filters and making sure they are the right size for a tight fit.


Air conditioning cough can be caused by several things including a dirty filter, no filter, dry air, moldy or Dusty AC.

Most of the time at is as easy as changing the HVAC filter or adding a humidity machine to the room.

But if the culprit is mold or extra Dusty duct work, you are looking at calling in a professional and having it cleaned properly.

Though no one wants a cough or any type of allergy symptom, when it comes to your air conditioning, your cough is a red flag that something is not right with your air handler.

Taking it as a sign that it is time to do some maintenance on your AC can save you a lot of money down the road.


20 Ways to Lower the Humidity in Your House

Are you wondering how to lower the humidity in your house? You are not alone, as a lot of people feel a sense of discomfort and unhappiness when they deal with super high humidity levels. And that’s why it makes a lot of sense to find new, creative ways to lower home humidity as quickly as possible. With that in mind, here you have a few tips that will help in this situation.

1.Use a dehumidifier

A dehumidifier is one of the simplest tools you can use to keep the humidity levels as low as possible. It’s highly recommended to invest in a good dehumidifier since it allows you to ensure proper airflow circulation, all while eliminating any humidity from the air. Ideally you want to keep the unit away from furniture or any walls, unless it has air vent on the top.

2. Clean the downspouts and gutters

You want to do this because they will carry water away from your home. It’s a good idea because if you don’t do this, you will end up with high humidity levels in your home. Plus, it’s a good idea to restrict watering plants to bare necessities, just to be safe. The more restrictions you have in this situation, the better it will be as you do want to avoid complications.

3. Keep fresh-cut firewood outside

Why is this important? The most important aspect to consider is that freshly cut firewood has large amounts of water in it when you store it indoors. You want to leave the firewood outside so all that water will evaporate. If you don’t do that, then you will increase the humidity levels inside. Even if it doesn’t feel like a lot, in a situation like this, every little thing counts, so you might as well want to take that into consideration just to be safe.

4. Bring all your plants outside

Don’t keep plants indoors. They end up increasing the humidity levels and that’s the type of thing that you want to avoid. Ideally you want to keep them outside and you will be just fine. You could also keep them in a single room, however that room will have lots of humidity, so you really need to figure out what works for you here.

5. Keep the AC drip pans and drain lines clean

If you keep them clean and unobstructed, it will be a lot easier to avoid any humidity issues. The AC will remove all the humidity from your room. However, if the AC is not working properly, then you will have issues with this approach. You need patience to do this right, but it will be worth it.

6. Vent your clothes dryers outside

The reason you want to do that is that you end up generating a lot of humidity if you do this inside. There’s no real benefit coming with performing this activity inside anyway, so you have to figure out what works for you and how you can adapt to the entire process.

7.Add double-glazing to your windows

When you do that, you will have less humidity and that on its own can be a very important aspect to consider. Double-glazing really brings in front great results, and the best part is that you can avoid severe condensation without spending a whole lot of money. It’s the best of both worlds and you should totally check it out.

8.Aerate your attic and basement

Normally these are two of the places in your home where you will have a lot of moisture. If you start bringing in fresh air in there, you will start removing more and more moisture naturally. It’s one of the best approaches you can have and it does work really well if you do it right. We recommend you to test it out and perform this task often to avoid moisture and dampness in your home.

9. Use a fan in your kitchen

If you cook often, you will generate humidity in your kitchen. It makes a lot of sense to use a fan or anything that will bring in fresh air and push the humidity away too. This is an important aspect to think about, and it will offer you a very good experience every time. In a situation like this, you need to start easily, and this approach does make a lot of sense.

10. Open the fireplace damper

The fireplace damper allows you to push moisture away from your room. It’s a good way to lower the humidity naturally, and we believe that you should always consider it as one of the first things you can do when you deal with lots of humidity inside your home.

11. Open up the windows

This is simple, but it helps you push humidity away, all while bringing in dry air from outside. You have to figure out what approach works for you, and it all comes down to delivering the best results and having the right approach here.

12. Cover your food while cooking

Another interesting thing to do when you are cooking is to try and cover the food. This will keep the humidity under control. Alternatively, you could use a slow cooker, which brings pretty much the same experience and great results you would expect. It’s always a good idea to find alternative solutions, and it can be very well worth the effort all the time without any worries.
Lower your Humidity

13. Take cold, short showers

Hot showers will generate steam and that will obviously increase the humidity levels in your home. Not only that, but if those hot showers are long, then you are further increasing the humidity levels. You need to pay a lot of attention to this, because the more you take hot showers, the more humidity you are generating within the entire home.

14.Replace the carpet if it’s a model that retains moisture

Some types of carpets like the fluffy or very thick ones tend to retain a lot of moisture. They will also end up capturing dust mites and bacteria. It makes a lot of sense to replace your carpets with simpler ones. Make sure that you go with carpets that are not going to retain any moisture. And if you do that properly, it will be more than ok.

15.Add wrap or tubular insulation

Insulating tubing works great for the cold water pipes. It will help decrease sweating, and the best part is that you will have less humidity in your home. Even if it seems like a simple thing to do, it will make quite the difference.

16. Repair the door and window frames

When you have issues with the window and door frames, the first thing you want to do is to repair them. These frames can bring in moisture into your home, and that’s the last thing you want to have. Even some simple repairs can make quite the difference, and all you need is to give these a try, it will be well worth it in the end.

17.Insulate the crawl spaces

The best method you can use for insulating crawl spaces is through using a plastic vapor barrier. This is not that hard to do actually, and it will bring in front some pretty impressive results. The idea is to know how to perform proper insulation, and if you do it right, it will be a very good experience.

18. Waterproof the concrete basement walls

Waterproofing these walls will be a major way to deal with excess humidity. Most of the time concrete walls will bring in humidity to your home. That’s why waterproofing them is so important, and you should treat this as a priority to avoid any possible problems.

19. Treat the foundation with Hydroclay

Hydroclay is known for waterproofing tunnels. It’s a water-absorbing clay, and it will seal the basement where you have water infiltrations. Waterproofing your foundation with this will make quite the difference, and it will help you keep your home safe. Plus, you get to deal with humidity the right way, and that on its own can deliver quite the difference.

20. Vinyl wallcovering

Using vinyl wallcovering can be a very good idea. The trick here is that this type of wallcovering will help trap the moisture and basically keep it out. If you ignore this, it will lead to mold growth. So that’s certainly something to keep in mind.


It’s very important to find great, creative ways to keep the humidity levels as low as possible within the entire home. If you have low humidity levels within your home, you will breathe better, your skin will feel better, and you will have a great sense of well being. It’s important to take all of this into consideration, and the results can be very good every time.
