Does A Dehumidifier Cause to Cool a Place?

Much ink has been split in proving that a dehumidifier does cool a room or not. Discovering the facts we have to go through all the observations and theories that are being put forward in this regard. Some of them say that dehumidifiers cause a cooling effect.

While the others claim that the dehumidifiers generate heat. let’s clear out all the doubts and queries that you might be holding in your mind.

Dehumidifiers in Action:

Dehumidifiers are electronic equipment designed to eliminate moisture, humidity, or dampness from the air. Certainly useful in areas where the air is condensed, promotion of formation, mites, dust particles, and musty smell due to excess humidity.

How Does A Dehumidifier, Work?

A dehumidifier works on a principal such as a refrigerator. The moisture that is removed from the air is submitted to the dehumidifier which leads to passing over the cold, refrigerator cool

Dehumidifier Cause Cooling Effect:

A dehumidifier decreases the water content of your house or your room. If you have doubts as to how it causes the cooling effect. We can say there is no direct cooling as of the air conditioner. However, removes a plethora amount of humidity. As it allows your body sweat to evaporate abruptly from your body. Thus causing a cooling effect.

Dehumidifiers Vs Air Conditioner:

Clearing up the dust by letting you the facts and observations. Dehumidifiers are not capable of cooling the air as Air conditioners do. On the other hand, the Air conditioners with the most modern technology not only cool the air through evaporation but also act as the Air cleaner or dehumidifiers.

The big disagreement between a dehumidifier and an air conditioner is that the air conditioner segregates the two facets of the system whereas the refrigerant is in different aspects, one inside and another outside. So, if you think of a dehumidifier as an air conditioner with both sides in the same room, it’s only gonna slowly heat the room.

Generates Heat:

Moving on toward the very opposite pole of matter. We observed that a few are up with the discussions that running a dehumidifier generated heat with the temperature will rise, as a result of running this appliance the fan motor and compressor warm up the room slightly. Along with this heat is released when the air is condensed with humidity.


While knowing if a dehumidifier cools a room you must understand that dry air feels much cooler to the human body than condensed air. You can say the consists released by the specific dehumidifier can condense both heat and cool. A dehumidifier consists of two sides of a coil one is cold that condenses all the humidity and the hot side consumes extra heat.

What Can Cause a Dehumidifier to Blow Hot Air?

One of the several causes is the grubbiness of the unit. When the water tank is full and you don’t get to remove it or you haven’t cleaned the unit for a month or so it will surely generate heat as a result.


First of all, I would like to give you an overview of the concepts and misconceptions in regards to dehumidifier cause cooling or not. Searching for an appliance that can kill two birds with a stone. If you’re thinking that you can clean sweep the humidity as well as take your dehumidifier to remove humidity.

Well, we are despicable about it but we won’t be able to do so. Because a dehumidifier does only give you an extra boost of comfort and ease by removing all the Moisture

These appliances use warm and cool coils to remove moisture. It works by collecting air as a small fan draws in air from the place it is kept and then the air is passed over coils. As the condensed air reaches the warm and cools spontaneously. 

It causes a reaction to separate the water from the condensed air. Which is then collected into the attached bucket or removed via the drain pipe.

Dehumidifiers tout significant usefulness. Although a dehumidifier does not elicit cool air like your air conditioning system, it does draw moisture from the air. Which, in return, can make your home feel several degrees cooler and significantly more comfortable.

One of the greatest benefits of adding a dehumidifier to your home is that it staves off mold, mustiness, and other hazardous environmental perils. Excess moisture can damage the valuables in your home.

From wooden ceilings, curtains, floors, cabinetry, and linens, and your clothing nothing is protected from enduring moisture in your home. Thankfully, the addition of a dehumidifier can remove excess water even in hard-to-reach places.

Similarly, you don’t need the dehumidifiers in every room of your home to feel a difference. In most cases, your air conditioning system’s built-in dehumidifier will do the trick.

But amplifying another dehumidifier in areas of your residence that need slightly more help is a tremendous idea. Bathrooms, the laundry room, and kitchens, for instance, are more liable to condensation.

Use Of Dehumidifier During Summer:

If you are under a sunny sky and the climate of your house feels very hot and humid. An ideal humidifier will help to remove sweating or perception and the heat produced will be lessened. However, if you are turning on a dehumidifier in a place that isn’t humid at all then this dehumidifier will surely generate more heat.

If the climate is hot and humid, dehumidifiers will work to your advantage. They will remove the humidity, and the heat generated will be less than if you hadn’t used it. If you live in a place that has no humidity, then dehumidifiers will generate more heat than they remove. 

Scientific Approach:

According to the Law Of Thermodynamics, adding motors or devices to your room system is not going to cool your room; instead, it will generate more heat, but there are a few circumstances or cases in which it may do so.

If there is a lot of humidity and condensed air dehumidifiers will surely give you a cooling effect by making the air lighter and humid free atmosphere you will probably feel much relief and cooling effect.

However, due to the water’s specific warmth, drying out the room will make it feel less drastic to human perception. For example, maximum degrees and zero humidity will be much cooler than 89 degrees and 100% humidity.

Wrap Up!

To sum up the discussion we can say that dehumidifiers may be able to cause merely a colling effect as they recently reduce humidity. Which is the fundamental cause of disturbance in the room.

Along with this humidity is so heavy and muggy due to the presence of water vapors in the air. Dehumidifiers therefore can cause cooling effects but they can not be compared to Air Conditioners.

Not denying the Law Of Thermodynamics that turning on several motors brings about heat. We can have the right answer by saying that the dehumidifiers had neither cooling nor heating purpose.

However, it can act for both heatings and cooling the air depending upon the provided conditions and climate change. Therefore, the fact we have here says dehumidifier does affect the temperature of a room.
