Does a Dehumidifier Help Cool a Room?

The dog days of summer. The dog days of summer is actually an ancient Roman saying.

It came about because the hottest muggy months of the year , July and August are associated with a called star Sirius.

Sirius is a word that actually means dog or large dog. Sirius is at its brightest at this time of the year because it rises with the sun during those two months.

The belief is that the star is so bright during those two months, it actually adds heat to the sun making those two months much hotter than the rest of the year.

Hmm..

Yes a dehumidifier will help to cool off a room. Humid air feels hot. So when a dehumidifier is used to extract humidity out of the air, the air will feel cooler as a result.

A dehumidifier itself does not do anything to cool the room. It is not an air conditioner and does not blow cold air.
But by using a dehumidifier to remove enough humidity from a room, the air will automatically feel cooler.

You know the feeling, especially if you live in an area where the humidity can knock you out in the summer.

The AC feels like it’s doing nothing and your clothes are soaked with perspiration nearly as fast as you leave the house.

Dehumidifier vs. Air con

A dehumidifier extracts humidity from the air. And a air conditioner lowers the temperature of the air.

Though the AC can have a dehumidifying effect, there are times of the year when the humidity can overcome the air conditioner and cause it not to work properly.

A dehumidifier can remove moisture from the air and allow your air conditioning to work properly again.

Yes.  One way you can help your air conditioner to cool the house during the hottest summer months is to use a dehumidifier.

When the humidity is extra high, it puts a strain on your AC.

And since it doesn’t seem like the AC is running very well, most people turn the thermostat down.

That causes the AC to run that much harder.

And with the moisture being so high, turning down the thermostat
typically causes the unit to freeze up.

And then you have no cool air till you let it thaw out.

A dehumidifier is used to bring the humidity down to a comfortable level,

That will also allow the air conditioning to function without the extra load and do much more to cool off your house.

That can save you a mint on HVAC repairs, spiking energy cost, or even having to replace the air conditioner when it is mistreated for so long.

Heavy humidity also facilitates and houses mold and dust mites.
Breathing junky air also adds to the discomfort of high humidity in the summer.
A dehumidifier will not only help your air conditioner work better, it will also help clean your air, adding another level of comfort during the muggy months.

Does a dehumidifier heat up a room?

Yes it does.
The heating effect of a dehumidifier is much like the temperature coming off the back side of a window air conditioner.
But instead of the backside of the air conditioner being outside of the house it is inside.

Why is my dehumidifier blowing hot airWhy is my dehumidifier blowing hot air?

It is part of the function of the dehumidifier. The hot air exiting the machine is actually the normal temperature for the exhaust of the unit.

A dehumidifier is basically a window air conditioner that does not blow cool air. It creates condensation exactly the same way as a window air conditioner does but instead of the condensation dripping outside, it drips into a collection tank. so just like the way a window air conditioner exhaust hot air, a dehumidifier does the same.

It does seem pretty odd that lowering the temperature in the house is probably one of the main reasons you would purchase a dehumidifier, only to have the room that the dehumidifier is placed in feel much warmer.

Though a dehumidifier will work well to reduce the humidity and the overall heat in the house, the room you place it in will feel like you have a damp space heater running.

So if you plan on being in the basement, it’s good ideal to turn on the dehumidifier and let it run a couple of hours and then let the temperature in the room cool off before you use the basement.

That being said, a dehumidifier is not a space heater. It is a humidity extractor.
Though warm air may come off of the dehumidifier, it should never be used to heat up a room.

Most humidifiers will not run below 65 degrees anyway. But as a precaution, if yours does, be sure to use it for the reason it was purchased and don’t keep it running when the humidity is low and the temperature is cool.

Are dehumidifiers loud?

Yes they can be. If you were trying to do something that requires silence. You’re not going to be able to run a dehumidifier in the same room.

Most manufacturers have perk their ears up over the complaints of dehumidifiers being too loud.

That has resulted in quieter units, some that even claim to be as quiet as a refrigerator.

But most devices that are used to affect the climate of a room, wether it be a dehumidifier, a humidifier, air purifier, or air conditioner, typically run pretty loud.

HVAC units can usually be outfitted with dehumidifiers and air purifiers which can dramatically lower the level of noise that can come from using the typical standalone air devices.

In fact there are many advantages to using your HVAC for cleaning air and the humidifying as the air conditioning is running.

Not only will you be able to significantly lower your noise DB, you will also have the advantage of your central heat and air being able to clean or extract humidity from the whole house instead of one room at a time.

There are some in duct air purifiers that are easy to install but for the most part getting a qualified HVAC technician  to recommend and install your dehumidifier and air cleaning devices is a better choice.

Summary

A dehumidifier is not an air conditioner or a fan and does not cool off a room like an air conditioner does. But when the humidity is extra high it can help your air conditioner to function better.

Heavy humidity in the air will cause your air conditioner to feel like it’s not running. But a dehumidifier can extract the humidity from the air and give your air conditioning the capacity to do its job again.

The one caveat is that dehumidifiers run hot and exhaust hot air so whatever room the device is placed in will feel extra warm.

Using dehumidifiers and air purifiers in the HVAC is it a way of avoiding the noise associated with these machines and the hot air that is produced from a dehumidifier running.

Keeping cool in the hot muggy months of Summer is not just about turning the air conditioner on and turning the thermostat down lower. It is about controlling indoor humidity and allowing your air conditioning to function without having to strain.

A dehumidifier is a device that will lower the level of moisture in your air and allow your air conditioning to work properly without spiking your energy bill and increasing the probability of malfunctioning AC.
