When running your air conditioner, magic happens. The refrigerant turns from a liquid into a gas that cools the air and later is changed back into a liquid. Cool air is created to ensure your home stays cool and comfortable. During the cooling process even more magic happens. The moisture in the air is removed which will naturally dehumidify the air. Your air conditioner brings cool and dry air into your home for the ultimate comfort. However, when you discover that the air conditioner isn’t removing the moisture and the humidity has been unchecked, you may wonder if there is a problem with your air conditioner. Air Supply Heating & Air Conditioning will share what may be the reason why your air conditioner has failed to remove the humidity from your indoor air.
Set Thermostat to Dehumidify
When you can see condensation building up on your windows or can feel the moisture in the air your air conditioner isn’t removing the moisture properly. When the home is becoming increasingly humid start by checking the thermostat. If the thermostat has been set to the “On” setting the air conditioner fan will run but not the air conditioner. So the fan running but the air isn’t cooling nor is the moisture being removed. Before calling a professional HVAC service, make sure the thermostat is set to “Auto”.
Clean Dirty AC Evaporator Coil
Another reason why the humidity isn’t being removed properly may be due to dirty evaporator coils. The evaporator coils is like a magnet for moisture. It is the evaporator coils that collect and capture the moisture in the air. Moisture will build up on the coils, and if dirt or other debris is present they will come together forming a layer of gunk over the coils. If the coils become too dirty they lose their ability to capture the moisture in the air. There will be moisture flowing free throughout the home. Not only will you have humid indoor air, but the air ducts will develop condensation and eventually mold. It is very important to keep your evaporator coils clean. You will need a professional technician to come and clean the coils as they can be bent and damaged if not cleaned properly.
It is Bad to have an Oversized AC Unit!
For those who have fallen in the trap that a bigger air conditioner unit is better, then it is sad to say this is a wrong and common misconception. There are a lot of problems with having an oversized air conditioner unit including the failure to remove humidity. Because a large air conditioner cools down the space too quickly and then quickly shuts off, the air conditioner never has the time to remove the moisture from the air. An oversize unit will chill the inside of a home fast but this is a problem. The air conditioner needs time to remove moisture and when the cool cycle ends too fast, the moisture will not be removed. You should avoid installing an oversized air conditioner and if you did, you may want to replace it.
