It's the middle of summer, and your air conditioner is running non-stop, but your house is still humid. You've checked the settings, and they're all correct, so what's going on? Chances are, there are a few things wrong with your AC that are preventing it from dehumidifying your home. In this blog post, we will discuss some of the most common reasons why an AC unit isn't removing humidity from the air. We'll also provide solutions to fix these problems!

Reasons Your AC Won't Dehumidify

Dirty Condenser Coils

One problem that could affect your AC unit's ability to dehumidify your home is if the outdoor condenser coils need to be cleaned. The coils help transfer heat from the inside of your home to the outside. If they're dirty, they won't be able to transfer the heat as efficiently, and your AC unit will have a tougher time trying to cool and dehumidify your home.

If your condenser coils are dirty, you need to clean them to get your system to dehumidify your home again. While you can clean these yourselves, we recommend calling a professional as trying to do it yourself could result in you voiding your system's warranty.

Wrong Size

Another reason why your AC may not be dehumidifying your home is that the unit isn't the proper size for the home. If your cooling unit is too small, it won't be able to remove all of the moisture from the air. On the other hand, if your air conditioner is too large, it will cool the air too quickly and won't have enough time to remove the humidity.

This is an easy fix as all you need to do is find an AC unit that is the proper size for your home. When it comes to choosing a new air conditioner, you have to look at the size of the house or room it's cooling, how shaded the room is, how many people regularly occupy the room at one time, and how many windows are in the room. All of these factors are why we recommend contacting a professional before choosing your new cooling system. The experts at Korrect Plumbing, Heating & Air Conditioning, Inc. can guide you through the selection process to help you find an energy-efficient and adequately sized unit for your space.

Frozen Evaporator Coils

The problem with your system could be that your evaporator coils are frozen. This happens when Ice and frost accumulate on the coil surface, preventing the refrigerant from absorbing heat to cool and dehumidify your home. Frozen coils can be caused by an unclean air filter, a clogged condensate drain, a blocked condenser unit, or insufficient refrigerant levels., it prevents the AC from removing moisture effectively from the air.

To fix frozen this problem, you'll need to thaw out the coils. You can do this by turning off the AC and setting the thermostat to fan only. Then, open up all the doors and windows in your home to get some air circulating. Avoid using anything like a hair dryer on the frozen coils, as if it gets too close, it could melt the coils.

Too Old

If your old reliable AC is more old than reliable these days, that could be why your system isn't dehumidifying your home. If your air conditioner is more than ten years old, it's time to start shopping for a new one. Older units are less efficient and don't work as well as they used to. They also can't remove as much humidity from the air as newer units.

While you can try to repair your system after about ten years of use, any fix will be temporary and is just delaying the inevitable. Your best bet in this situation is to shop for a new air conditioner. At Korrect Plumbing, Heating & Air Conditioning, Inc. we offer newer, more efficient models at various price points so you can find the system that best suits your needs without breaking the bank.
