What Should You Look For in a Small Window AC? (3 Favorites)

Small window air conditioners  generally cover right around 150 square feet for 5000 BTUs. 250 square feet for 6,000 BTUs.

BTUs which stands for British Thermal Units can be a confusing metric to base your AC needs off of.

Most people are unfamiliar with what BTUs actually are.

That’s okay,  so am I.

An easier way to figure out what size AC you actually need is to base it off the square footage. Which is generally labeled on the box near the same area where the BTUs are listed.

The formula for square footage is length x width.
In simpler terms, if you have a room that is 10 ft going one way and 12 ft going the other way, you multiply 10×12 to find that you have 120 square feet of space.

Using the same formula, you can find out how many BTUs you need by simply multiplying the square footage by 25.

Sq ft x 25 = BTUs.

But to be fair that is a rough estimate and doesn’t take into account variables like high ceilings, hot climates, and rooms that are directly in the Sun.

If any of those variables applies to you, then you should probably consider stepping it up to the next size.

What should you look for in a window AC?


1.  Sq. feet covered
Getting the right AC to match your square footage is important. Air conditioning is not like a race car engine that works better when it has more power. Two large of an air conditioner can actually make the room extra humid. Not to mention the extra energy required to run a larger air conditioner.

2.  Physical Size
It’s important to match the physical size of a window AC to the actual window it’s going in. Though with a small window air conditioner, it will not usually be the case, it is possible to get a AC unit that is just too large for your window.

3.  Watts/ energy usage
The amount of watts an AC uses will impact the amount of money you spend to run the unit every month. It’s a good idea to check the wattage to find a unit that is relatively low.

Beyond this small list, it is really just bells and whistles.

Some of the extras you can expect to find in a Window AC are:


1. Dehumidifier

Humidity on its own can make a room feel hot without the actual temperature being that high. A dehumidifier or dry mode as it is usually called, will reduce the humidity in the room without using the refrigerator function to cool.

2. Auto shut off

Auto shut off on a window AC is an excellent feature because it will turn the AC off once the desired temperature is reached.

3. Remote control

A remote control with your window AC is one of the best features you can look for when shopping for an AC. Can you imagine any other item that has made life easier than a remote control?

This list of small window air conditioners is comprised of units that use 5,000 and 6,000 BTUs or cover 150 to 250 sq. ft.

Can You Use a Window Air Conditioner Without a Window?

Can you use a window air conditioner inside a room?

Yes,  you can use a window air conditioner without a window inside a room. Though there is not any type of professional conversion kit you buy, there are some very good DIY methods.

Rather just purchase a portable AC that you do not have to modify? Check out the Black & Decker 12000 BTU portable AC with you dehumidifier and fan Here.

A lot of people say that window air conditioners can not be used other than through a window.

But that’s not my experience.

I have seen them modified to work in shops, garages and basements.

The thing is you’ve got to know a little about how a window AC works before you can make it work without a window.

But it is actually not as difficult as you may think.

The main things you need to know are how to vent it and how to capture the condensate.

The first thing you need to know is that heat is generated and expels out of the entire back of the unit when it is running.

That means you are not going to be able to bring the unit in and put it on the table, then turn it on and have it cool off the room. I wish it were that easy.

The heat it creates will overtake the cool air coming out and you’ll end up with a hotter room everywhere except right in front of the air conditioner.

“You’re going to have to fashion a way to capture the heat coming out of the rear and vent it somewhere. Preferably outside or into the attic. A closet would even do if there isn’t any thing in it that the heat would effect.”

Sometimes using a window air conditioner without a window may be as easy as cutting a hole in the wall and setting up the window AC the same way you would if it were in a window.

That is probably a good option if you’re committed to keeping it there.

But if you want to preserve your walls, there are other ways.

How to Vent a Window Air Conditioner Without a Window

In the example here, a storage bin is modified to fit around the rear of the AC and flexible duct is used to vent the heat into the attic.

The lid is cut and duct taped around the opening to create an air tight seal.

The reason a storage bin works is that it gives plenty of room for heat the to go.

That’s important because if the heat gets trapped, the AC will overheat and will not cool down.

Another important thing to remember is to leave the side grills open.

The grills and the sides are basically there to allow fresh air in to help cool off the AC. So make sure that they are not drawing air from the vented heat.

Does a Window Unit Have to be in a Window?

On the bucket part of the storage bin, there is a vent box cut into and duct taped to the plastic.

That makes it easy to connect the flexible duct, but it’s completely optional. You can get away with taping the duct straight to the plastic.

The duct is fished into the ceiling. Which is fine because it is a garage.

If you having to vent off into a closet or another room, you can use cardboard to  fill the space around the flex duct.

As for the condensation,

Since the air conditioner is sitting on a wooden frame to elevate it to the level of the lid on the storage bin.

This leaves plenty of room to put something underneath the air conditioner to capture the condensation runoff.

It is also possible to rig up some sort of hose for the condensation run off to drip into.

Something you might see on evaporative cooler.


Convert Window AC to Portable

Basically the whole thing is a DIY conversion of a window air conditioner into a portable air conditioner.

Portable air conditioners run exactly like window air conditioners except for they already have the flexible duct connected and come with ready-made kits to vent them out windows and doors.

They also have a bucket to capture the condensation.

But most of the supplies you need to do your own DIY indoor window air conditioner are usually around the house or don’t cost too much

And if you’re on a budget a low in window air conditioner even with the DIY supplies to convert it is cheaper than the low in portable air conditioner.

Sitting in my shed.

You can find them in garage sales and tucked away in storage sheds quite often too.

Plus it’s pretty fun when you get it done and it works good.

Good luck.

Not for you?

Fashioning a way to use a window air conditioner without a window can be a lot of work.

And if you don’t have a window AC sitting around somewhere that needs to be used, it’s work that you may not want to do anyway.

Portable air conditioners already have everything you need built into the unit and apart from finding a place to vent it to, are ready to go.

Another option is ventless portable ACs.
This type of air conditioner does not require any type of vent to exhale the heat, but it does require adding water regularly.

Here are a few choices we recommend if you decide to purchase a portable AC rather than go through the trouble of converting a window AC to use inside a room or house.

My Portable AC Keeps (5 Pain in the A** Issues)

Does your portable air conditioner have a few issues that keep coming up regardless of how many times you think you have the problem resolved?

A portable air conditioner can be a very useful way to keep cool when you want the ability to move the AC from room to room.

But it is no secret that portable does not exactly mean convenient when you’re talking about an AC.

And the number of issues that can keep coming up with a portable air conditioner may make it seem like it’s not worth it in the first place.

LG 10,000 BTU -Smart Portable Air Conditioner

Here is a list of some of the most popular issues that pop up with portable air conditioners.

1. Portable AC Keeps Turning Off

A portable air conditioner that keeps turning off is most likely getting too hot.
There are a few different reasons this could be happening.

a. Kink in the exhaust hose. If the exhaust hose is not positioned so that the heat expelling from the AC is not able to exhaust easily, heat will build up around the compressor eventually causing it to shut off.

Solution: Make sure the hose is not wound up or is kinked. Also, be sure that the hose is not being obstructed where the air exits.

b. Automatic shut-off is enabled. Make sure you don’t have the timer set to cut off the AC before you’re ready.

c. The temperature programmed into the thermostat has been reached.

d. Vent grates are clogged or obstructed.

The vents on the side of the AC are there to provide ventilation to the compressor and evaporative coil department inside the machine. If these get covered or clogged, the unit can overheat.

2. Portable Air Conditioner keeps filling up with water

All refrigerated air conditioners create condensation as the air is pulled across the cooling coils. That’s why there is a drain pan in the first place for the portable air conditioner.

If the pan keeps filling up with water, there are only a few things it could possibly be:

a. The air is extra humid. Humidity comes and goes and sometimes the humidity and the ambient air is extra high which means that you’re your portable AC is going to create that much more constant as it pulls the humidity out of the air.

b. Dry mode. Make sure that your unit is not in dry mode. Dry mode is specifically the dehumidification mode that extra humidity from the air. Sometimes the simplest answer is right in front of you. Maybe the thermostat has been changed to dry mode at some point and has gone unnoticed.

3. Broken mister. Most portable ACs evaporate the condensate at a rate that it is able to expel out the window along with the exhaust heat. If you have a portable AC that at one point never filled up with water, but now fills up quickly, there is probably a broken flinger that is not doing its job. Causing all the condensate to fill up the pan instead of being flung out the window.

3. Portable AC not cooling



a. Exhaust hose has come off either partially or all the way.
The exhaust air that is pumped out the window, as you know, is very hot and humid.
If the hose somehow comes unattached even partially, and you will have a mix of hot and cold air coming from the machine which will cancel the cool air.
b. Filter needs to be changed. The filter on an AC is the first place to look for just about every AC problem. If the filter is clogged, then there is no way for air to be pulled into the unit freely enough to condition the air and re-release it.
c. Exhaust hose is kinked or covered.
If the exhaust is not allowed to freely Flow away from the AC. The buildup of heat will cause diminished cooling.
d. Ventilation grates
The ventilation grates on the side and top of your portable AC are there to help cool the evaporative coil and compressor department.
If they are covered or gunked up, you will experience diminished cooling from your unit.
e. Faulty sensor
Portable air conditioners contain a sensor that measures the temperature of the air being pulled into the air conditioner so that the thermostat has a baseline to cool off of.
If the sensor goes bad or gets dirty, it can give a wrong reading that can either prevent your AC from getting cold enough or vice versa, making it too cold so that it freezes over.
If you’re a handy person, it’s not that hard of an operation to check the sensor. Otherwise, it’s not that hard to call a handyman over to check it for you.


GE Appliances 12,000 BTU 3-IN-1 Portable Air Conditioner

portable air conditioner keeps turning off4.Portable AC keeps freezing


a. Clean or replace the filter. A dirty filter will inhibit airflow. If the air is not capable of moving past the refrigerant coils fast enough, the humidity in the air will freeze instead of drain off.

b. Thermostat setting is too low.
If the thermostat is set too low, then the condensation that is supposed to drain or evaporate from the machine will freeze.
Solution: run the AC on the fan only to thaw out the coils.

c. High humidity
When you are experiencing higher than normal moisture in the air, the moisture in the air has a better chance of freezing before it is evaporated. This is especially so if you have a dirty filter.
Solution: run the unit on dry mode
The dehumidifier function (dry mode) is made to extract humidity out of the air faster.
Also when the humidity inside of the room is too high, often you will find that running the dehumidifier only is enough to bring the comfort of the room back to a decent spot.

6. Portable air conditioner keeps blowing the breaker.



a. A breaker shuts off when it is overloaded. That is the entire function of a breaker.

If the breaker is shutting off when the portable AC is started, there’s a good chance that you have too many appliances on one circuit.
Turning the breaker back on every time it snaps will cause it to eventually get to where it won’t stay on at all.

b. Unit is too small.

If the unit is too small you may find that it is running Non-Stop causing it to trip the breaker.

c. Turn the thermostat down

Turning the thermostat down may lessen the load on your breaker and allow the machine to keep running.

If you do not have an overloaded circuit and the AC continues to trigger the breaker, then you should call an electrician.

6.Portable AC keeps tripping the power strip.

Most surge protector power strips are not rated to be able to handle the startup of an AC. It is recommended that you never plug an AC into a power strip. Power strips are meant to be temporary solutions that are unplugged and stored afterward.

The same goes for using an extension cord with a portable AC. Most extension cords are not rated to be able to handle the surge of an AC compressor starting up. If you need to use an extension cord, be sure that it is rated to be able to handle a large appliance like an AC. 

Though a portable air conditioner can be a good idea when you want the convenience of being able to move an air conditioner from room to room, it’s important to remember that convenience doesn’t exactly mean “ease of use”.

Proper use, maintenance, and upkeep are the name of the game. As long as you keep your filter cleaned, the unit properly exhausted, and keep up with the drain, making sure the department isn’t filled and that it is not neglected to the point of growing mold, your unit should last a long time.

If window access is the primary reason that you’re thinking about purchasing a portable air conditioner, there are also evaporative portable air conditioners available that don’t require a window to vent out of. Just food for thought

Does a Window AC Use Outside Air? (It’s Not What It Seems)

Window air conditioners do pull air in from the outside but it is probably not how it seems. 

The idea that the cool air you feel comes from a Window AC comes from outdoors is not true. At least in the case of refrigerated air.

But window air conditioners do utilize outdoor air in other ways.

Window air conditioners use fresh outdoor air in 3 different ways.

1. Fan mode
2. Ventilation
3. Evaporative

1. Fan mode allows you to to use your AC as a fan by opening a small ( very small) opening to allow fresh air in through your AC. Some AC s give you the ability to mix the outdoor air by opening the fan vent.

2. Ventilation. The ventilation grates on the side of the unit are deceiving because they might give you the idea that air is being drawn into the unit to be cooled and released into the room or house. But the ventilation grates are actually to pull air into the condenser coil department to help cool the machine and keep it from overheating.

3. Evaporative window units do pull outside air into a room. The entire action of an evaporative window cooler is to pull outside air through water soaked pads into an area for cooling.

There are two distinctively different styles of window air conditioners. Refrigerated air and evaporated air.

Both are designed to sit in your window and blow cool air into your room. Only one blows air in from the outside of the house and the other conditions air from inside of the house.

Refrigerated window air conditioners are the more popular of the two types .

 At least in recent years. Evaporative window air conditioners used to be the main technology or method for cooling the house.

There was a big industry surrounding evaporative air coolers and all of the supplies you needed to mount a evaporative air conditioner on the outside of your windows and house. But those types of air conditioners have now taken a back seat.

Refrigerated air is the status quo in this generation.

What’s the difference in evaporative and refrigerated window air conditioners

Refrigerated air is cooled by blowing air over coils that have refrigerant flowing through them.
Evaporated air is cooled by blowing air over water.

Do refrigerated window air conditioners bring in fresh air from outside?

No. Refrigerated window air conditioners recirculate the air already in the room.

The design of a window air conditioner makes it easy to assume that air is being pulled into the unit from the outside due to the ventilation grates located on the sides and top of a ac window unit.

But those grates are now there to pull air into the refrigeration process. They are there to pull air into the back of the unit to help ventilate the condenser coils.

The cool air you feel from a window air conditioner is room air that is pulled in through the face of the unit and is circulated over the refrigeration coils. Then it is blown back into the room through vents at the upper point of the face of the ac.

A refrigerated window air conditioner sits in a window entirely to exhaust hot air through the rear of the unit outside.

But evaporative window air conditioners do get their supply air from the outside of the window.

The basic premise of a window evaporative cooler is to pull outside air over absorption pads that have been soaked in water and blow the water cooled air into the room.

Evaporative window air conditioners have a few different names that you may recognize them by.

The most popular is “swamp cooler” but recently they are more likely to be called “vent less air conditioners” or “exhaust free air conditioners

They are called vent less air conditioners because they do not require a way to vent hot air coming from the rear of the unit.

The simplest way to explain an evaporative cooler is to call it a fan that blows air through a stream of water.

In the case of window evaporative coolers, they require a direct hookup of water that continuously soaks pads that are inside the perimeter of the air conditioner.

And though they do not require any way to exhaust them, they do require a source of water that is either connected directly or added manually.

Certain “Portable air conditioners” are usually the ones that carry the moniker “ventless air conditioner” or “exhaust free”.

Whenever you find an air conditioner that says it does not need exhaust or is ventless, you know that you are looking at an air conditioner that needs a supply of water.

In other words you’re going to have to fill it with water on a regular basis.

Swamp Cooler Warning


And any appliance that has to be filled with water or extracts water like a dehumidifier will have to be cleaned regularly to avoid the production of mold and bacteria in the machine.

Legionnaires’ disease originated from poorly or never maintained evaporative air coolers that were allowed to have standing water in large commercial buildings. The bacteria was allowed to grow unchecked and then have access to the airstream through the air conditioning vent system.

A good reminder when you are dealing with any type of machine that affects humidity.


The other type of portable air conditioner is the one that does require a way to vent it.


And even though it is portable and can be placed throughout a room, it still has a large hose that has to be strung across the room to a window in order to expel the hot air created in the refrigeration process.


Portable but not exactly convenient.

There are some pretty clever ways to convert a window air conditioner into a portable air conditioner but the same problem exists of being able to find a place and a way to exhaust it.

Regardless, some areas just do not lend themselves too easy window access or water access for that matter.

So the terms “portable” and “convenient” are not exactly interchangeable when it comes to air conditioning.

Pros and cons of refrigerated window air conditioners.


Colder air.

Less maintenance. Refrigerated window air conditioners have a small filter that needs to be blown clean from time to time. And a complete cleaning only necessary on a yearly basis.

Do not need any source of water.

Extracts humidity

Easy to cover for the winter months.


Exhaust hot air from the rear.


Pros and cons of an evaporative window air conditioner.


Does not exhaust hot air from the rear.


Not as cool.

Adds humidity. The fact that they are nicknamed “swamp cooler” gives you the idea of what type of air quality you can get from an evaporative window air conditioner.

Needs a constant source of water. Either by directly hooking it up to a water faucet or hose connection or by filling it manually.

Requires much more regular maintenance to ensure that it doesn’t have issues with mold and bacteria.

Must be emptied of water when not in use.

It is easy to see that refrigerated window air conditioners are a much better choice if you have a convenient window to put it in.

If you do not have a convenient window, then choosing a vent less evaporative portable air conditioner is probably an easier solution than a refrigerated portable air conditioner.

But that is also determined by your access to a window or access to an attic.


There are two choices when it comes to window air conditioners.

1. Refrigerated
2. Evaporative

Refrigerated window ac units recirculate room air over cooling coils and returns the air as cool or cold.

Evaporative window units pull outside air through absorption pads that are continuously soaked in water.

Refrigerated air is more convenient and doesn’t require a source of water regardless if it be directly hooked up or a unit that you manually fill.

Evaporative window ac units have long been renamed” swamp coolers” because of the amount of humidity they add to a room.

But portable vent less air conditioners that use evaporative air are a welcomed solution when you have a area that needs cooling but you do not have window access to vent a refrigerated ac unit whether it be a fixed window unit or a portable that has to be vented with hoses.

Does Arctic Breeze Actually work?

Homemade AC Coil Cleaner- 5 DIY Recipes

Is it time too deep clean the HVAC system again?

Keeping the components of the central heat and air unit that you rely on for warm and cool air clean are essential for not only getting the best results out of your AC but also making sure your energy bill stays manageable.

The air conditioning evaporative and condensing coils carry a lot of weight in determining how well your AC unit is able to cool off your house.

When they get dirty it
can decrease the capacity of your unit to cool your home and increase the amount of energy it takes to do so. A air handler with dirty coils can actually increase your energy bill as much as 40%.

But the good news is, you do not have to pay somebody or spend a lot of money on a specific degreaser or cleaner to revive your AC’s copper coils back to their original shine and performance.

A perfect homemade AC coil cleaner for both your evaporative and condenser coils is as easy as going to your cupboard or medicine cabinet and pulling out a couple of household items that most people are sure to have around.

Homemade AC coil cleaner- Homespun Recipes


1. Vinegar and alcohol

  1. Half cup of vinegar
  2. Half cup of rubbing alcohol
  3. Baking soda

If this sounds familiar, it’s because it’s basically the same ingredients as DIY window cleaner.

Nevertheless, alcohol and vinegar are an excellent combination to make sure that any tiny debris stuck on the coils breaks completely loose.

If you have debris that won’t come off without a little scrubbing, baking soda is a natural cleaner that has a mild abrasive element to it that will help with scrubbing without damaging the coils.
Vinegar is also one of the best cleaning tools to remove mold and mildew.

2. Soapy water and baking soda

  1. Water
  2. Dish soap
  3. Baking soda

Another easy recipe with ingredients that most people have around the house. A bucket of water with a little bit of dish soap and some baking soda if you need something abrasive to loosen up anything stuck to the coils.

With any type of homemade AC coil cleaner, remember to use a light brush and take it easy on the coils. You don’t want to scratch the coils or bend the fins that protect the coils.

3. Bleach and Water

  1. Bleach
  2. Water

A three to one combination of water and bleach (bleach being the smaller portion) in a spray bottle is an excellent homemade solution to clean the coils on your air conditioner.
Not only will bleach kill mold and mildew, it will also help prevent it from coming back.

Warning: If you don’t like the smell of bleach or if you have any type of adverse challenges with bleach, you probably want to stay away from this option. The reason is there is a chance that the smell will creep into your ventilation and into your home.

4. Vinegar and water

Using a homemade AC coil cleaner made up of simply vinegar and water is an excellent easy do-it-yourself solution for cleaning the coils in your AC unit.

Equal parts:

  1. White vinegar
  2. Water

White vinegar is one of the most effective mildew and mold cleaners there is. It not only removes mold, it leaves behind disinfectant properties that hinders mold from coming back.

5. Compressed air and dust buster

What could be an easier solution to cleaning the AC coils than using an air compressor to simply blow off any debris.
Using a compressor to blow the debris and dirt off of the coils is very effective but just hitting the area with a sudden force of air will scattered dust and debris all through your AC unit.

So before using forced air to clean the unit, it is best to take a dust buster or vacuum with the right attachments to get and get as much dirt and debris up as you can beforehand.

Another reminder. The fins that surround the coils are made out of very light tin. Be careful not to barrel down with the air. Keep it three or four inches away to ensure you do not bend the fins.

5.0 out of 5 stars I love this!

5. Garden hose

On the evaporative side of the AC which is outside, you will find that keeping the area tidy around your AC unit will help your AC run much more efficiently.

Simply taking a garden hose and applying some of pressurized water to the outside of your unit and even into any of the inside that you can actually reach with a garden hose spray attachment will help your AC run easier and along with keeping the air conditioner filters replaced will give you less opportunities with your unit freezing over.

Why Does My Room Smell Musty?

Musty is a word that is sometimes used to describe the feeling you get from a stale or a stuffy room. It’s usually a smell that you just can’t quite put your finger on, but you know that there is something that is not quite right. But in most cases that “not quite right feeling” is the presence of mold and mildew.

Why Does My Room Smell Musty?

A musty smell in a room is an indicator that you have moisture coming in somewhere that along with dirt or grime has become a source of food and nutrition for mold and mildew to take root. Mold can take root and grow very fast when given the right ingredients. A musty smell should be taken seriously as a warning that there is an issue with mold close by.

I’ve had a personal experience with this.

In my neighborhood there was an issue with heavy rains that washed over the curbs and went up the driveway and eventually seeped into the backdoor of the house.

It didn’t seem like much at the time so we really didn’t do too much about it besides put some towels down to soak up the water. And it was the very back of the house that doesn’t get a lot of traffic anyway.

A couple of months later I noticed a rotten smell coming from that area.

I pulled out a bookshelf that was in that corner and pulled up the edge of the carpet only to find that dark green and black mold had spread heavily underneath the carpet and had made its way all over the wall and the back of the shelf, including all the books on it.

It was pretty shocking to see how much the mold had taken over.

We had to take the carpet up and remove and replace the drywall on that side of the room.

Luckily the mold did not turn out to be the dangerous Stachybotrys or black mold.

All that to say that if you have a musty smell in your room, it’s a situation that you should take seriously.

Mold can do more destruction than you may be giving it credit for. And do it much faster than you may think.

Mold can also exasperate allergies and is known to be a trigger for asthma.

What you are looking for in your room when you have a musty smell is an inappropriate source of moisture.

According to the National Library of Medicine , Mold spores are practically everywhere and there is really no way to get away from them or keep them out of your house. But without an adequate source of moisture, they cannot grow and colonize into a problem.

So the fundamental thing you’re looking for in the case of a musty smell is moisture and the supply of that moisture.

Wet moldy carpet

Why Does My Room Smell Musty in The Morning?

What could be some reasons your room smells musty?

  1. Wet carpet
  2. Wet drywall
  3. Window seals
  4. Excessive humidity
  5. Dew
  6. Leaves
  7. Moldy items in trash
  8. Moldy food laying around
  9. Mold inside of the HVAC duct work

1. Wet carpet

Remember that you are looking for the source of the moisture.

If you have wet carpet then the ideal is to figure out why it is wet.

Some reasons may be as simple as a soaking wet towel laying on the carpet or has there been a big spill that was not cleaned up?

If you have a large area that is damp, then there may be a leak that has sprung from a pipe beneath the flooring.

it will be worthwhile for you to peel the carpet back and make sure that your floor is not soaking wet beneath.

And if it is, you should make it a priority to have it fixed as soon as possible to avoid further damage and mold growth.

2.  Wet drywall

It can be a smell can be coming from the walls if a pipe inside of the wall has busted. Examine the walls and see if you can find any areas where they are bubbling, swelling, or peeling which would indicate that moisture has gotten inside of the drywall.

3.  Window seals

One area that moisture can get into the house easily is the windows. If the windows are not sealed properly, you can find moisture creeping in around the window. If it has been going on for a long time, you will also find the frame around the window rotting.

4. Excessive humidity

If you live in an area with a climate that is prone to high humidity, you may find that it is the humidity that is causing moisture to build up inside of your room. If this is the case, then mildew is probably showing up on your walls or ceiling somewhere.

This is the case in many basements. The level of humidity inside of the room causes condensation to build on the walls and create a natural food source for mold and mildew.

The best solution in that case is to use a dehumidifier to pull moisture out of the air so that it does not have a chance to become a problem in the form of mold.


5.  Dew

Many people claim to be more concerned with the dusty smell in their house in the morning time.

That morning musty smell is usually associated with the moisture that develops in the air in the early morning hours.

It’s the moisture that is commonly known as dew.

Dew can help turn the volume up on the smell of mold and mildew in the morning.

6.  Leaves

Leaves, specifically in the Autumn season can pile up in gutters and around the house and make an excellent environment for mold to take root. And once the mold has colonized inside of the leaves, any sort of rustling around caused by the wind or by kicking the leaves can unleash mold spores into the air.

7.  Moldy items in trash

Sometimes a musty smell is coming from a moldy item that has been thrown away and just sitting there stinking. The trash can is one of the first places to look when you smell something musty in your room.

8.  Moldy food laying around

Moldy food can cause a very pungent musty smell when it is laying out or in the trash can. Items like half eaten hamburgers and apple cores are best disposed of in the main kitchen area where the trash is taken out more frequently.
If you have a musty smell in your room, looking for any food that has been left out to mold is a good place to start.
Another place that you can find moldy musty smells is in the kitchen sink where the garbage disposal is. If the garbage disposal has not been cleaned properly in a while, you are liable to smell moldy food coming from there.

9. Mold in HVAC ductwork

If there is mold in your ductwork, you can be sure that it will be distributed throughout the house every time the heating or air conditioning comes on.

According to this study, mold can be commonly found inside of an air handler, specifically the wheel fan blades, the ductwork, and the cooling coil fins.

Another source of mold coming into the house through the ductwork is the evaporative coils. Dirty evaporative coils contain all the ingredients for mold to flourish and find its way inside of the house.

If you have a musty smell coming from your HVAC ductwork, cleaning the evaporative coils located on the outside section of your unit is a good place to start to reduce the volume of mold spores coming in.

Another trouble area for HVAC systems when it comes to mold is the drip pan. If the drip pan is not draining sufficiently, water can build up in the pan and become a source of mold.

Clearing any blockage from the drip pan to the outside drainage is also a good way to ensure that you do not have mold growing and coming in through your HVAC.

UV systems are often used to target areas like evaporative coils and drip pans so that mold does not have a chance to colonize and become a problem in your air quality.

Is There a Fan that Blows Cold Air vs. Just Air?

Is there a type of fan that blows cold air versus just plain air?

Not really. Once you add cold air to a fan, it basically becomes an air conditioner or an evaporative cooler.

An air conditioner is really just a fan that blows refrigerated air.

Albeit much more sophisticated than that since it it dehumidifies as it cools the air, but fundamentally the same.

And a evaporative cooler is a fan that blows air off of pads that are soaked in water.

Technically a fan is just a motor that has propellers attached to it to move air.
The temperature of the air that a fan is  moving may seem to be cooler because of the wind chill effect that it is creating,  but the temperature is the same going in, as it is coming out of a fan.

And logically once you begin to cool the air off any other way, whether it be through a refrigerant or damped pads,

you can no longer call it a fan because you have begun to condition the air with an outside element, which then makes it an air conditioner.

But whatever you want to call it, the point is to get some cool air on you when you’re hot.

diy air conditioner

DIY Air Conditioner

You have probably heard of DIY air conditioners that are basically fans that blow over ice, done with beer coolers.

If you want to take the time and put in a little more effort, this type of DIY fan/ AC is a excellent way to get a fan to feel like an air conditioner.

The ideal is to cut circular holes, a large one on top for a fan to blow into, and two on the sides to connect some flexible duct too. (This is done using a circular blade saw, the type that you use for a door handle, only much bigger. And a power drill.)
Connect connect the flexible duct to the hose that you cut on the sides using duct tape or aluminum tape.
Feel the beer cooler with ice up to the point of the flexible duct.
Plug the fan in and turn it on.
Enjoy the cool air coming off of the ice through the flexible duct.

your going to need a constant supply of ice as well as a cleaning schedule because you are looking at a recipe for mold when you combine a container of water with heat in a dark place.

evaporative cooler

Evaporative coolers work much like the DIY beer cooler air conditioners you see on YouTube.

They are usually window type air conditioners that have a water supply that keeps pads soaked with water as a fan blows cool air off of the water into the house.

Evaporative coolers or Swamp coolers have one major flaw, they increase the humidity in the room.

You’ve probably heard the saying” it’s not the heat, it’s the humidity”.

That’s because the humidity can make it feel much hotter than it actually is during the warm and hot months.

And it’s not an accident, that evaporative coolers have taken on the nickname ” swamp coolers. And thats because in the right conditions, an evaporative cooler can make a room feel like a swamp.

That’s not to say that there’s not a place for them, everyone likes the feeling of cool air coming off of the ocean or a lake.

But it’s all the same premise.

Portable Air ConditionerPortable Air Conditioner

Refrigerated Air Conditioners have the advantage of being used as a fan when you don’t need the colder air.

And the advantage of reducing the relative indoor humidity which can be at the source of the temperature inside of the house.


Are you looking for a fan that blows cold air like an air conditioner?

Unfortunately you’re not going to have too much luck with a fan blowing cold air like an air conditioner unless you can first cool the air off before the fan blows it.

Which is technically what an air conditioner is.

And evaporative cooler is a type of fan that blows air off of water which makes the air feel cooler. But this type a fan is also called a swamp cooler because of its tendency to fill the house full of moisture, making it feel like a swamp.

And since, the high humidity in warm weather is as much a factor in the heat, adding more humidity to the air it’s only going to make it feel that much more uncomfortable.

But if you’re just looking for a personal fan and want to make it a little cooler, they do make small evaporative coolers that feel just fine blowing on you whereas trying to cool down a whole house or room may make it feel balmy.

There are plenty of DIY solutions for making a fan blow cold air. Most amount to the same technique of blowing the air over ice or water.

A better solution is a small mobile refrigerated air unit. They will not only blow cold air, they will help reduce the humidity in the room at the same time.

The biggest downside is they have to be vented. So that means either using a window air conditioner or running the provided ductwork to a window or attic.

Dehumidifier vs. Fan for the Bathroom

Using a dehumidifier versus a fan for indoor humidity. Which one is better?

Excessive humidity inside of your home can happen for multitude of reasons including flooding, leaks, poor insulation especially in the basement and crawl spaces, or the rainy season has just descended on you. But the most common place that you find excessive moisture in the air is the bathroom.

Regardless, living with high humidity inside of the house not only effects your  level of comfort and overall wellness, it also effects the structure of your home as well as your belongings.

Dehumidifier vs. fan 

A fan can be useful to reduce indoor humidity as long as it is blowing dry outdoor air into the room, but it is not controlled or measured.

On the other hand, a dehumidifier will reduce a controllable , measured amount of humidity and does not depend on the outside air being dry.

If you have an issue with high humidity inside of your home, the humidity outside is more likely going to be very high than low.

In a circumstances where the humidity is not overbearing but not exactly helping you out either, placing fans around the room can have a drying effect on the air. If you were trying to paint or some other type of similar art project where you need a dry environment, having a couple of fans osculating and moving air around the room can probably give you the amount of dryness you need for your project.

But other indoor humidity issues, like a damp basement, you need a way to control the amount of humidity in the room because of the problems of mold and fungus it comes with it.

The only way you can get this type of control is by using a dehumidifier that will extract the humidity out of the air to the proper relative humidity is reached.

Dehumidifier vs exhaust fan

Dehumidifier vs exhaust fan

Most people have exhaust fans in their bathrooms so that the moisture left in the air by the shower and bath can be expelled out of the house so but it does not have a chance to promote mold in the drywall and window frames.

But though you typically do fine exhaust fans in the bathroom and the kitchen, they are really not found too much in other areas of the house.

Dehumidifiers and fans or exhaust fans are not enemies. Nor do they have to work exclusive of each other.

Using the exhaust fans in the bathroom in the kitchen or a great idea and do a great job. But they do not work for the whole house.

A Dehumidifier can only help an exhaust fan to reduce the humidity in the house. Likewise, exhaust fans can only help with the dehumidifier do its job.

“The main difference is that a dehumidifier can extract and remove the exact amount of humidity that you need it to whereas a fan doesn’t have the capacity to be measured.”

The second way a fan can help a dehumidifier is the use of a high-powered air mover fan. An air mover is a fan created especially for drying and is usually used on construction sites as a means of speeding up the time it takes for paint to dry and blowing away the fumes left behind by the paint.

An air mover is not generally a piece of machinery that you’ll want to use in your home unless you plan on removing everything from the walls and putting everything away that can be blown away.


A fan and a dehumidifier can both help reduce humidity in the air but the difference is, it is the job of a dehumidifier to remove humidity from the air and it does so according to how it is programmed.

A Fan on the other hand, even though it does have some drying capacity because oh the natural blowing on something to dry it aspect, does not extract humidity from the air and does not do nearly as good of a job as reducing humidity as a dehumidifier. Nor is it measurable or controllable like a dehumidifier.

One exception is an exhaust fan that is put inside of a bathroom or kitchen for the express purpose of removing moisture created by showering and cooking. Another exception is the use of a commercial air mover, which is a high velocity fan meant that is used to help dry out construction sites as well as remove fumes.
Yet even in these cases it’s not measurable or controllable.

But as a fan, a dehumidifier is only good for blowing hot air on you. Not usually the effect you want from a fan.

When is it Too Cold to Run Air Conditioner for Dehumidifying?

One of the functions of an air conditioner is that it simultaneously lowers the humidity inside of the house when it is running. But unfortunately as the temperature drops outside so does the performance of the AC as both a cooler and a dehumidifier.


Air conditioners and dehumidifiers are not meant to be run when the temperature is below 65° for any extended time.

There are two reasons for this.

1. Freezing up
2. Oil is to Thick

1.  Freezing up
When the air outside is too cold, the warm air that would normally turn into condensation as it crosses over the cooling coils is too cool already and instead of forming condensation it turns to ice.

2. 2. Oil is to Thick
AC Compressors are made to work in warm weather which means that they require a thicker grade of oil. This is because when the temperature is warm, it thins down the oil to a good operating thickness. But when the temperature outside is not warm enough to thin the oil, it remains thick and does not supply the level of lubrication needed without causing a risk of damaging the air conditioning compressor.

Most of the time there is not any use for an air conditioner in the cool months. And turning the heater on helps dry the air out as fast or faster than a dehumidifier.

On the occasion you need to turn on the air conditioner in the winter for a few minutes, the risk of damaging it is minimal. But turning on the air conditioner and leaving it to cycle on and off is asking for problems.

If you have excessive moisture caused from a leak or flooding and need more than just a fan or a heater to help dry up the air in the winter months, dehumidifiers can be purchased that can be operated at much lower temperatures.

WHEN IS IT TOO COLD TO RUN AIR CONDITIONER FOR DEHUMIDIFYING?These dehumidifiers come in two different types.

1. Dehumidifier with defrost
2. Desiccant dehumidifier

1.Dehumidifier with Defrost

A Dehumidifier with defrost mode is exactly what it sounds like.

Since the standard dehumidifier runs exactly like a refrigerated air conditioning unit which pulls warm air over the AC coils and condenses it into a bucket or outside by the means of a garden hose.
Freezing over when the temperature is too low is a problem.
What’s the solution? Adding a defroster to the unit that cycles on and off keeping the cooling coils from freezing over.
These dehumidifiers are made with areas like a cold damp basement in mind.

2. Desiccant dehumidifier

Desiccant dehumidifiers work by the means of a chemical adsorber which is called a desiccant.

A desiccant can be as simple as a product cold “damprid” which is a product that comes in a small container that is opened and left to absorb moisture in a small area.

A desiccant dehumidifier is a little more complicated than that. The desiccant in a dehumidifier is not only used as an absorber it is also heated up to release humidity also.

A two-part process where humid air is pulled into the dehumidifier and absorbed, reheated into humidity form again and then caught in a tank as condensation.

Desiccant dehumidifiers do not have the capacity to pull large amounts of moisture out of the air like the regular refrigerated condensing units do.

In fact they have been described as a way to keep dry air dry.

This is probably a good point to tell you that the chemical that they use to adsorb air is the same chemical in gel packs and does have an odor.

Nevertheless there are some applications like condensation in the bathroom where a desiccant dehumidifier maybe preferred because it does not rely on a loud compressor running to do the job.

A desiccant dehumidifier can also be a good alternative and a damp basement is long as it is not excessively damp.

Again, running a compressor base dehumidifier can be pretty loud, definitely loud enough to interfere with the TV or sound and video recording.

But a desiccant dehumidifier is definitely not useful in a remedial flood damage type situation.


When is it too cold to run an air conditioner?


When the temperature outside gets to about 65°, the air passing over the cooling coils on an air conditioner has a tendency to start freezing up. At that point not only will you not have AC, you do not have any of the dehumidifying properties of an AC either.

Another problem with running the AC in the winter is that the oil that is used in the AC compressor is a summer specific thicker grade that thins in warmer weather.

When the temperature outside is not warm enough, the oil does not thin out properly leaving the compressor to work without the proper lubrication which could mean eventual damage to your unit.

Are you going to turn your AC on and winter and have a complete breakdown? Probably not.

There are times when you you may need to turn on the air conditioner in the winter for a few minutes to make sure it works, in that kind of circumstances you should be fine.

If you are using your AC to dehumidify, the same problems exist.

High humidity usually comes with high heat so once the Heat has tapered off, the humidity tapers off too.

If you are having a problem with humidity inside of your house in the cool months, there may be moisture getting into the house through other means.

Dehumidifiers that work in cooler temperatures can be purchased.

For excessive humidity in the winter, dehumidifiers with defrosters and defrost mode are available to help pull the large amount of humidity from your air.

If humidity in the winter is only a casual problem whereas the windows are getting condensation or you have an art room that is too damp for your paint to dry, you might go with a desiccant dehumidifier instead.

Desiccant dehumidifiers use a chemical absorber that pulls a much lower level of humidity out of the air is much quieter than the typical dehumidifier.

and if you are going to use one in a small area like a arts and craft room, beware that the chemical used in these dehumidifiers does have a small odor.
