Learn How to Handle a Musty AC Unit Inside Your Home

Discovering that you have a musty AC can be very disheartening and annoying. This is often the result of mildew and mold, which can reduce the quality of your indoor air. Today, we’re going to take a look at how you may be able to remove the musty odor yourself or with the help of an HVAC technician.

Clean or Replace the Filter

Your air filter is responsible for capturing dirt and debris so that harmful pollutants don’t get recycled back into your home’s air. These filters get clogged up after a pretty short period of time, possibly causing a musty smell. Make sure that you’re cleaning or replacing the filter every one to three months.

Clean the Unit’s Coils

Your system has two primary coils: the evaporator coil and the condenser coil. When the evaporator coil gets dirty, this can sometimes lead to various problems, including a musty odor. To ensure that you don’t accidentally damage the coils, call an HVAC tech to have them cleaned.

Check the Condensate Drain Line

One of the most common causes of a musty smell is a clogged condensate drain line. This happens because condensation from the evaporator coils drips into the condensate pan and then to the drain line, taking dirt and grime along with it. This can cause excess moisture, which will often lead to mold, mildew, and — you guessed it — a musty smell.
