Does A Dehumidifier Cool A Room

If you’ve ever had a dehumidifier, you know how it works. It traps and removes moisture from the air in your home. But what is humidity? And how does that affect the air we breathe? The answer to both questions is: not much.

Heat is a form of energy.

Heat is a form of energy. It’s the result of the transfer of energy between objects, or in this case, between molecules and atoms.

Heat can be measured in many different ways, but we’ll focus here on just two: absolute heat and thermal energy. Absolute heat refers to any quantity of heat transferred through space (or time). Thermal energy is measured in joules per second—a unit that measures not only absolute temperature but also amount and rate at which it changes during an interval.

For example: If you were baking cookies at 350°F (177°C), your oven would be emitting 125 watts directly onto its surface; if you had left those same cookies inside for another half hour without turning down their temperature from 350°F (177°C), then they’d have been baking for about 125 minutes using just one watt more than before! This means there was more than enough transfer from ovens across distances such as rooms into walls around them through air circulation systems throughout homes where people live so everyone could enjoy delicious treats without having burned themselves after eating them all up too quickly!

The three states of matter.

You may not have heard of it, but there are three states of matter. They are solid, liquid and gas.

Solid Matter: All the minerals in your home are examples of solids. If you were to break a rock into pieces, those pieces would still be considered solids because they remain together and do not flow like liquids or gases.

Liquid Matter: Water is an example of a liquid because it flows freely within its container (like water running off a roof). Another example is ice cubes in your freezer; when frozen solid, these cubes become one big chunk that floats on top of other chunks as long as there’s enough room for them all to fit comfortably together!

Gases: Air is an example of gas because it can flow freely through cracks between two containers without getting stuck inside either one like oil does when poured into another container with no open space left around where air could go instead.”

Humidity, coolness and comfort.

Humidity, coolness and comfort are not the same thing.

The humidity level in your home is measured by a hygrometer, which measures the density of water vapor (i.e., how much water there is) in air. The higher that number gets, the more it will affect your comfort levels—which can make you uncomfortable or even sick if not kept at an acceptable level.

To keep this from happening, dehumidifiers are used to remove excess moisture from indoor spaces so that they remain comfortable while also reducing their chances of becoming moldy or damaged by bacteria growths like mold spores that thrive on moist environments with high levels of carbon dioxide (CO2) relative to oxygen (O2).

A dehumidifier does not cool the air in any way.

A dehumidifier does not cool the air in any way. It removes moisture from the air and that’s it!

A dehumidifier is a device that traps humidity in its filter, which prevents it from escaping back into your home. This keeps rooms at an ideal level of humidity (around 40%), which helps keep your skin healthy and prevents mildew buildup on carpets or other surfaces.


Dehumidifiers are great at removing moisture from the air, but they don’t actually cool or heat your home. If you want to keep your home cool and comfortable, it is important that you install a central air conditioning system. You can also use fans or portable AC units if needed.

A dehumidifier can help to cool a room by reducing the level of moisture in the air. This can make the room feel cooler and more comfortable, as well as help to prevent condensation and mold growth.

Dehumidifiers can reduce indoor relative humidity from 50%-100% to 30%-50%. By doing this they give off the cooling effect. The temperature may not exactly change, it could even be a little bit higher, but it’s the humidity that changes.

How A Dehumidifier Works
How A Dehumidifier Works

How A Dehumidifier Works

A dehumidifier works by pulling in moist air from the room and passing it over a cold coil. This causes the water to condense on the coil, and the dry air is then passed back into the room. As the water collects on the coil, it collects in a collection water tank or reservoir.

Dehumidifiers can be used in both warm and cold climates to help improve indoor air quality and prevent mold and mildew growth. In warm climates, dehumidifiers can help to reduce the level of humidity in the air, making the room feel cooler and more comfortable. In cold climates, dehumidifiers can help to prevent condensation and mold growth.

Health Benefits

The health benefits of a dehumidifier include:

Removes or reduces allergens:

Studies show that humidity levels that are higher than 50% can attract dust mites, mildew, and mold. They are allergy triggers and can bring a host of health problems. Allergens such as dust mites, mildew, and mold spores cannot exist in a dry and cold environment. In humid climates, these allergens remain as invisible occupants and thrive. They cause allergic reactions.

Allergic reactions include wheezing, dry skin, skin rashes, and eye irritation. They also cause sneezing, a stuffy or runny nose, and itching. By controlling the humidity levels, dehumidifiers can be beneficial. They can help those who have an allergy to mold growth or other allergens. This can be particularly helpful to people with asthma.

Prevents asthma attacks:

Dampness in the walls of your home causes the growth of mold. This can cause respiratory illness and trigger asthmatic conditions. Dust found in upholstery and carpets is also known to trigger asthma attacks. Strong cleaning products are allergy triggers, too. This is especially true in cases of childhood asthma.

Breathing difficulties that do not become asthma attacks can also be serious. They can cause respiratory distress. Airborne allergens and an excessive moisture level can cause chest congestion. They can disturb your sleep.

Over time these issues can become severe and affect your immune system. Dehumidifiers that also act as air purifiers can remove these allergy triggers. They can remove the growth of dust or mold and help prevent respiratory conditions.

Improves immune systems:

Did you know that allergens can also compromise your immune system? For instance, sneezing or coughing over several days can be debilitating, causing weakness. Making sure that your home has a healthy environment becomes important.

A dehumidifier helps make your home conducive to a healthy immune system.

Soothes the skin:

Allergens such as dust mites, animal dander, and pollen can trigger skin irritations. If the humidity level is over 50%, these allergens can become active and cause a lot of trouble. Eczema is one such condition. It involves skin inflammation and intense itching. It is one skin ailment that may worsen when there are dust mites. 

According to studies, the development of eczema has increased by around 20% in the last few years. The bottom line is that allergens need to go. That can happen with the new advanced dehumidifiers that are now available.

Keep food fresh:

We know how harmful food can be if it has got mold in it. Stale food can also cause gastrointestinal issues. You may not notice the mold spores if they are somewhere in your home’s crawl space. You may touch mold and not realize it. But it can end up in your mouth if you touch your mouth or start preparing your meal without washing your hands.

You may feel nauseous and not even realize it’s because of mold issues. But, it can get worse. You could get stomach cramps, diarrhea, and fungal infections. Using a whole-house dehumidifier can prevent mold growth in any part of the home.

Keeps insects away:

You will find small insects gravitating to a damp environment in your home. Crawl spaces, closets, and bathrooms are favorite haunts for insects. They get into your pantry, on your clothes, in your books, and lay eggs. It can become difficult to remove them all.

An ideal environment is dry and inhospitable for insects. That is where a portable dehumidifier comes in. You can move it from room to room. It helps keep the environment around you free of insects and also takes care of the moisture problem.

Reducing or eliminating musty odors in your home

Constant moisture brings with it mold and mildew. These leave a musty odor in the home. Dehumidifiers help to reduce the musty smell and leave your home smelling fresh.

Reduces the dust in your home

Dust can accumulate in your home and cause allergies to start up. When you use a dehumidifier, it reduces the dust particles in the air. You will have cleaner air and less grime in your home.

The home will be cooler

High humidity makes you feel hot and sticky. When you sweat and it is humid, your body’s cooling system doesn’t work well. But using a dehumidifier helps to remove the moisture and your body can regulate it better. You will feel cooler and more comfortable.

Helps you sleep better

High humidity makes it difficult to sleep. You will be hot and uncomfortable. Lack of sleep can affect you physically, mentally, and even emotionally. But when you use a dehumidifier and the humidity drops, you can have a good night’s sleep.


A dehumidifier can work with an air conditioner to make your home more pleasant. In most cases, what it cannot do is replace an air conditioner. Both a dehumidifier and an air conditioner remove humidity from home. But they do so in different ways.

A dehumidifier pulls moist air in. It eliminates it by passing it through cooler tubes and coils than the entering air’s dew point. The dew point is the temperature at which moisture in the air condenses from a vapor to a liquid.

 After removing the moisture, the device reheats the air before releasing it. This means that the air that goes out to the room will be warmer and dryer than when it entered.

An air conditioner also sucks in warm, humid air from your home, but it removes the heat and moisture. Moving air across refrigerant-filled coils cools the air. This allows moisture to condense and drain away while the heat collected goes through the air conditioner’s external unit. As a result, the air that returns will be cooler and dryer than it was.

Efficiently Using A Dehumidifier

To get the most from your dehumidifier, there are a few factors you need to consider.

Dehumidifier placement

  •       If your dehumidifier doesn’t have a top-mounted air discharge, don’t put it near furniture or walls.
  •       To avoid any unauthorised usage or consequences, leave at least 6-12 inches of space on all sides.
  •       When the unit is on, keep your doors and windows shut.
  •       To achieve the best circulation, put it as close to the center of the room as possible.
  •       Place it as close to the moisture source as possible while working with larger spaces. If you place it too far away, you will not feel your unit’s effects. 
  •       Avoid placing it near any furniture since this may obstruct your unit’s ventilation unless it’s a top-mounted discharge type. 
  •       Avoid putting it near any dust-gathering places, which could cause your unit to clog. 

Empty your water tank

Your dehumidifier needs regular maintenance. This includes emptying your water tank. Do not wait for your tank to be full because you may miss it, and it will overflow. This defeats the purpose you are trying to achieve.

Most dehumidifiers will auto-shut off when the tank is full. And have an indicator light to show the tank needs emptying. If you do not check this, dehumidification will stop until you empty the tank.

An easier way to deal with this issue is to get a dehumidifier with a drain hose. It can then automatically drain the tank without you having to monitor it. It drains it out into a floor drain, sink, or window. This is the best solution. 

Ideal operating temperature 

Make sure you are using your dehumidifier at the ideal operating temperature. The perfect temperature for a dehumidifier is 70-90 degrees Fahrenheit. If it goes below this, the coils will freeze over, especially for refrigerant dehumidifiers. This frost will damage your device. It will also stop working, and humidity will not reduce. 

Some dehumidifiers come with anti-frost sensors and auto-defrost. But if you see that you need to run your dehumidifier in temperatures below 65 degrees Fahrenheit, then get a desiccant dehumidifier. This one is ideal for lower temperatures.

Buy the right size dehumidifier for the room size.

Capacity From Area Vs Moisture Table

The capacity of a dehumidifier is usually measured in pints per 24 hours. Two factors determine the capacity you should get:

The size of the area you want to use the device in

Before dehumidification, the condition in the room or space.

Set your dehumidifier humidity level 

When you are setting up your dehumidifier, set your desired humidity level, this way, when it arrives at the ideal humidity level, it will switch off. It will not run continuously, using energy.


Dehumidifier Considerations


Dehumidifiers are an essential appliance to have in the home. They protect your health from the effects of high humidity indoors. They also protect your property from moisture damage.

We recommend you consider buying AC Conditioner Dehumidifiers and Frigididiers Portable dehumidifiers. Look for larger capacity units that will cost you less to run as they clear moisture faster. You can consider buying these dehumidifiers

Final Thoughts

Dehumidifiers may only give you the cooler effect after removing the moisture from the air, but it does not do the work of an air conditioner. It is better to get both devices so that they work together.
