Do ductless air conditioners dehumidify?

Along with heating and cooling, ductless mini-divisions can also dehumidify your home. It is an essential part of the cooling process. However, you can also configure your system to only control humidity when needed. A minisplit without ducts works much like a traditional air conditioner.

The air conditioner helps to remove moisture from the air as it cools the indoor environment. It's like having a tiny dehumidifier in your system. Ductless minisplit systems can dehumidify to some extent, especially if your ductless minisplit has a dry mode. However, mini divisions are the ones that dehumidify the most in summer and least in winter.

If you want to reduce the relative humidity in your home in the colder months, you will need a separate dehumidifier unit. The mini splits dehumidify through the condensation process like any other air conditioner. The cooling coil of the mini split indoor unit is cooled below the dew point of the air so that condensation can occur. Both can effectively remove moisture from the air, but with key differences.

A mini-split, set to dry mode, keeps releasing some cool air as it dehumidifies. Meanwhile, a dehumidifier only sucks in moist air to blow out dry air. It is recommended to use a dehumidifier during the winter, as it does not release cold air, it even increases the temperature by releasing warm and dry air. The dehumidifier consumes less energy and is much cheaper than air conditioners.

It is designed to reduce humidity, useful for coping with hot climates. It removes and dries the air in the house to make it more comfortable.

Ductless air conditioning

systems are easier to install and can control humidity throughout the house compared to typical ducted air conditioning units. Some dehumidifiers are installed directly into the air conditioning system and dehumidify the air as it passes through the ducts.

This option is ideal when you want to remove moisture from the air, dehumidify it, but you do not necessarily want to cool the air. Through that, the mini split continues to dehumidify and reduce air humidity and cool the air at the same time. A ductless air conditioning system includes a main outdoor unit and one or more indoor mini-split units connected by cooling pipes and electrical wiring. If you're trying to keep the indoor air in your home comfortable, you may want to consider installing a ductless air conditioner.

When you turn on your mini split or any air conditioner, it automatically removes some of the moisture from the air. The water in the air condenses into a liquid, such as moisture on the outside of a cold glass of iced tea on a humid day and separates from the air moving through the coil. When hot, humid air enters the humidifier, it crosses the condenser coils that reduce the air temperature. Unlike a typical air conditioning unit, a mini split can dry the air with a very small amount of cold air.

Pressing it will activate the “dehumidifier” function of your air conditioner (it's not really a dehumidifier), which will remove excess moisture from the air and improve your comfort. The key to allowing air condensation is to lower the surface temperature of the cooling coil below the dew point of the air. But can a ductless air conditioner remove moisture? We have investigated how these units work and what configurations they have available to get an answer for you.
