Does A Dehumidifier Cool The Room?

Dehumidifiers do not cool a room and can often have the opposite effect. While dehumidifiers can cause a room feel more comfortable by removing excess moisture, they will not cool the air like an air conditioner. If cooling is what you want, you will need to invest in an air conditioning unit in addition to a dehumidifier.

Dehumidifiers and Room Temperature

When evaluating the impact of a dehumidifier on room temperature, it’s essential to understand its primary purpose and its effects on air temperature. It’s a common misconception that dehumidifiers act as air conditioners, but in reality, they serve different functions.

Effects on Air Temperature

Dehumidifiers work by extracting excess moisture from the air, resulting in a reduction of humidity levels in the room. High humidity can make a room feel uncomfortably warm, even if the actual temperature remains constant. Therefore, using a dehumidifier can make a room feel more comfortable by lowering humidity levels, but it does not directly lower the air temperature.

While air conditioners and dehumidifiers both have the capacity to remove moisture from the air, the primary goal of an air conditioner is to cool down a room’s temperature. To achieve this, air conditioners use a refrigeration cycle that absorbs and releases heat from the room’s air. In the process, an air conditioner also reduces humidity, but its main function is to provide a cooler environment.

On the other hand, dehumidifiers only focus on removing moisture from the air and not on air temperature reduction. They do this by utilizing either a refrigeration process, where warm, moist air gets cooled and water droplets get collected in a reservoir, or a desiccant process, where a hygroscopic material absorbs moisture from the air. Regardless of the method, the aim of a dehumidifier is to maintain a healthy humidity level within a room, typically between 30-50%.

It’s worth noting that some dehumidifiers may slightly increase the air temperature in a room, as they generate heat during their operation. To balance this effect and maintain comfortable room conditions, it’s advisable to use a dehumidifier in conjunction with other temperature-regulating devices, such as an air conditioner or a fan.

Dehumidifiers play a crucial role in ensuring a comfortable living space by removing excess moisture from the air. They do not directly lower a room’s temperature like an air conditioner, but they can improve comfort levels by decreasing humidity.

If you understand the difference between these devices, you can make informed decisions about how to manage their indoor environment and maintain a comfortable home.

Pros and Cons of Using Dehumidifiers


Dehumidifiers can offer several benefits for homeowners looking to improve comfort levels in their homes. These appliances work by removing excess moisture from the air, providing a few key advantages:

  • Air quality improvements: By reducing humidity levels, dehumidifiers can help prevent the growth of mold and mildew, which can negatively impact indoor air quality and pose health risks.
  • Reduced allergens: Dust mites thrive in humid environments, which can aggravate allergies. A dehumidifier helps create a less hospitable environment for these allergens and can provide relief to allergy sufferers.
  • Odor reduction: High humidity can lead to musty odors in your home, especially in basements and other damp areas. A dehumidifier can help eliminate these unpleasant smells.
  • Protection of items in your home: Excess humidity can cause wood to warp, metals to rust, and fabrics to become damp and damaged. Using a dehumidifier can help protect your belongings from damage caused by excessive moisture.


While dehumidifiers offer a number of benefits, there are some drawbacks to consider before opting to use one in your home:

  • Energy consumption: Dehumidifiers use electricity to function, which can contribute to higher energy bills. The amount of energy used will vary based on the size and efficiency of the unit.
  • Cost: While the initial purchase price of a dehumidifier can range from affordable to expensive, there are also ongoing costs for filter replacements and maintenance to consider.
  • No cooling effect: It’s important to understand that while dehumidifiers can make a room feel more comfortable by removing excess moisture, they do not actually cool the air like an air conditioner. If cooling is your primary objective, you may need to invest in an air conditioning unit in addition to a dehumidifier.
  • Noise: Some dehumidifier models can be noisy, potentially disrupting the peacefulness of your living space. If you are sensitive to noise, consider looking for a quiet model or placing it in an area of your home where the noise will be less disruptive.

In conclusion, a dehumidifier can offer several benefits to homeowners in terms of improving indoor air quality and comfort, but it is important to weigh these advantages against the drawbacks before making a decision. This way, you can ensure that a dehumidifier is the right investment for your home and needs.

Alternatives to Dehumidifiers

In this section, we will discuss some alternative options to dehumidifiers that can help improve comfort levels in a room and have cooling capabilities.

Air Conditioners

Air conditioners are an effective way to cool a room while also removing some humidity from the air. Unlike dehumidifiers, they can lower the temperature in a space, providing both cooling and dehumidification effects simultaneously. There are various types of air conditioners, such as window units, portable units, and central air systems. In general, they work by pulling warm air through a cooling coil, which removes both heat and moisture from the indoor air, resulting in a cooler and drier environment.

Benefits of air conditioners include:

  • Effective cooling and dehumidifying capabilities
  • Variety of sizes and types for different spaces
  • Can be energy-efficient, depending on the model


Fans are another alternative to dehumidifiers that can help with cooling a room. Although they do not remove humidity from the air, they create air movement, which can make a room feel cooler by evaporating the moisture on your skin. There are many different types of fans, including ceiling fans, box fans, tower fans, and pedestal fans.

Some advantages of using fans are:

  • Energy-efficient cooling option
  • Easy to install and affordable
  • Can help improve air circulation in a room


Proper ventilation can also help improve comfort in a room and potentially lower humidity levels. By allowing fresh air to flow into a room and pushing out stale air, ventilation can create a cool and comfortable environment. There are several ventilation strategies to consider, such as opening windows, installing air vents, or using exhaust fans.

Benefits of good ventilation include:

  • Maintains indoor air quality
  • Can help regulate humidity levels
  • May provide some cooling effects, depending on the outdoor temperature
