Will a Dehumidifier Cool a Room?

Dehumidifiers are great appliances because they remove excess humidity from the air so that your home is not only more comfortable but a lot healthier as well. Too much moisture in the air can lead to breathing issues, upper-respiratory problems, and even mold and mildew, which can be quite dangerous to everyone who lives there. Fortunately, all of these things can be eliminated simply by purchasing a basic dehumidifier. If you’re curious about whether a good unit can make your room cooler, read on.

How Does a Dehumidifier Work?

Dehumidifiers are simpler than you think and also very effective at what they do. Once the unit is turned on, a fan draws in the moist air and it is passed over coils that are very cool. The cooler the coils get, the more condensation happens and the water that results drips into a bin or pan of some type. There is a heat recovery system that reheats the air and any air that is warmer than 35ᵒ Fahrenheit is actually dispersed back into the atmosphere.

Most units have a de-icing feature that won’t allow the unit to freeze over. The dehumidifier shuts off both when the bucket is full and when it’s reached a certain humidity level. As long as the dehumidifier is on, the various steps of the process continue and it produces excellent results every time.

What Does a Dehumidifier Do to the Temperature of the Room?

A good dehumidifier operates 24 hours a day, seven days a week to keep your home humidity-free. Although many people wonder if it can cause the room to be cooler, it is actually a combination of things that makes the room more comfortable. For one thing, since your humidity level is naturally going to be much lower in your home, it is going to feel much cooler even if the actually temperature hasn’t dropped.

Low-humidity temps always feel cooler, which is one of the reasons why a good dehumidifier can make the room feel much cooler and more comfortable. Removing excess moisture from the air makes the atmosphere much drier, which also brings down the temperature. Most people have noticed how cities with low humidity naturally feel a lot cooler than those with high humidity and a good dehumidifier works much the same way.

In addition to all of this, excess humidity is always inherently warmer so when your home needs this excess humidity removed, you’ll notice that it already feels much warmer than other rooms. Once the humidity is removed, you’ll automatically feel much cooler than you did before. This is just the way that humidity works.

Your AC Unit Also Contributes to the Temperature

Yet another reason why dehumidifiers can make the room cooler is the fact that they enable your air-conditioning unit to work much more efficiently. If you run your air conditioner for too long, your utility bill can be astronomical but a good dehumidifier can help. Dehumidifiers reduce the strain on your AC unit because they reduce the humidity in the room and this usually results in the air conditioner operating under less strain and for smaller amounts of time, saving you money on your electric bill.

If you’re wondering “will a dehumidifier cool a room?”, the answer is “yes” because it not only works with your air conditioner to make it run more efficiently but also lowers the humidity level in the room and therefore provides a much cooler overall feel.

Think of it this way. If you live in one city and it’s 80 degrees one day but has a relative humidity of 90%, it’s going to feel quite different than another city where it’s 80 degrees but has a humidity level of only 20%. This low humidity is instantly going to make the air feel drier and cooler even though the temperatures in the two cities are exactly the same.

How to Make the Room a Lot Cooler

Now that you know the basics of how a dehumidifier can be used to make your room a bit cooler, you might be wondering what you can do to make sure that this happens with your dehumidifier. If you have one of these units and want it to cool off a room in your home, here are a few tips to follow:

  • Place your dehumidifier in the middle of the room at least six inches away from any furniture or other appliances.
  • Close all windows and doors in the room for the best results.
  • If possible, place an air conditioner in the window and use a timer system so that it doesn’t work at full force all the time.
  • Do not run the AC and dehumidifier at the same time because they will cancel one another out; instead, let the dehumidifier run until it stops and then turn on the air conditioner for a while.
  • Do not set the AC at the lowest level but alternate the settings so that it doesn’t run continuously to keep things cool.
  • Do this for several hours and leave the room empty during this timeframe.

If it is your bedroom that stays warm all the time, you can follow these tips and cool the room down much more quickly than you think. In this case, the AC and dehumidifier will work together to make an uncomfortable room much more comfortable in no time.

Is the Room Actually Cooler?

With a dehumidifier in the room, it can feel much cooler regardless of what the actual temperature is. Moist air always feels hotter than dry air and since dehumidifiers remove the moisture from the air, the room is always going to feel cooler and much more comfortable. Dehumidifiers don’t actually cool the room; in fact, they add heat to generated energy so that the space is dehumidified. However, the end result is a much cooler feeling that enables everyone in the room to be much more comfortable.

If you live in an area that is particularly hot and humid, you can use three appliances together to create a much cooler feel. These appliances are the air conditioner, dehumidifier, and ceiling fan. Run the dehumidifier first, then the air conditioner, and keep the ceiling fan on the entire time to distribute the air more evenly.

High humidity can make the air in the room feel heavy and thick, trapping more heat inside of the room and making the room smell heavier as well. When you use a good dehumidifier, the water vapor caused by the high humidity is taken away from all of the room’s surfaces, leaving the room’s inhabitants a lot cooler and more comfortable.

Some Final Thoughts

Even though dehumidifiers don’t always lower the actual temperature in the room, they do remove a lot of the humidity so that the air is lighter and cooler afterwards. When you purchase a dehumidifier, make sure that you get one that covers the square footage in that particular room and always use it according to the directions.

Humid rooms are always going to feel hotter than dry rooms, which is why having a good dehumidifier is always a good idea regardless of the season. A less-humid room will keep you more comfortable all year long and it all starts with having the right appliances so that the humidity is eliminated and the room can feel cooler.
