How to reduce humidity with an AC without using a dehumidifier
Your AC can help lower humidity without needing a separate dehumidifier.
Using a lower fan speed and keeping the AC clean can improve moisture removal.
Closing doors and windows helps keep excess humidity out of your home.
The summer season comes with humidity that makes your house sticky and unpleasant. Although most people use dehumidifiers to solve this problem, your air conditioner can help you a great deal by simply using it the right way. AC are built for cooling air and removing excess moisture from it in the process. With a few changes on your side on how to use it, your air conditioner can lower the humidity in your house considerably without having to buy any extra equipment. Learning these practical techniques takes just a few minutes and can make a real difference in your indoor comfort.
SurveyLower the AC fan speed
One of the best ways to combat high humidity levels in a home is to turn down the fan speed of the air conditioning unit. When the fan is set on high speeds, air passes quickly through the air conditioning unit without being allowed enough time by the cold coils in the unit to absorb any moisture from the air. Lowering the fan speed to low or medium enables slower air flow past the cold coils and increases the absorption of moisture from the air.

Maintain the coils of your AC
The cooling coils of your AC do their best to dehumidify the indoor air. However, the efficiency of your AC coils can be reduced as they accumulate dust and dirt over time, and this makes it difficult for the coils to extract moisture from the air. If that’s the case, then the easiest fix is to change your air filter. You can also do this every one to three months or have your system professionally serviced annually.
Avoid auto-fan settings

The auto fan setting works against you, especially during the humid days, as in the auto mode, the fan shuts off once the temperature reaches your desired level. Even if the moisture is present inside the room.
However, if you switch your fan to run continuously, then the air will keep circulating through the cooling coils the entire day. This constant operation removes more moisture from your home and helps your AC cool better on humid days.
Stop moisture at the source
When you want to reduce the humidity in an area, then it also means that you are preventing extra moisture from entering your home. The first and foremost thing you can do is to keep the windows and doors of your house closed during the humid days.
Other than that, if you have any leaks in your plumbing or roof, then you need to fix them immediately. Furthermore, use exhaust fans in bathrooms and kitchens when cooking or showering, as these steps work together with your AC to keep humidity levels down.
