How to Tell If Your HVAC System Has Mold


Mold is one thing you definitely don’t want in your home. In addition to bringing down your property values, it can also have a detrimental effect on your household’s health. While mold is commonly seen on the ceiling or in the basement, it’s also possible for it to grow in your HVAC system. This doesn’t necessarily mean you need an air conditioner replacement, however, as simple maintenance can usually get rid of it for you. But first, you need to learn how to identify it.

In this post, Dependable Heating & Air Conditioning discusses how you can identify and get rid of mold in your HVAC system.


A musty odor is one of the most obvious signs that your HVAC system has mold. You can easily tell if this is the case if the smell increases the longer you run the air conditioner. The odor will be even more apparent if it has spread to the air ducts.

Visible Signs

The easiest way to identify mold in your HVAC system is to see it. Air conditioner mold is similar to the mold you might find in your basement, and may be difficult to remove. With that in mind, it’s best to search for HVAC repair companies that can get rid of the mold permanently.

Recurring Respiratory Symptoms

As stated before, mold growth in your home can be detrimental to the health of your household. This is because mold can cause issues from mild irritation to serious respiratory illnesses if left unchecked for too long. Therefore, it’s best to get rid of any mold in your home as soon as possible.

How to Get Rid of Mold

Cleaning your HVAC system is one of the best ways to get rid of mold. The first thing you should do after sighting mold is put on a mask to prevent the spores from entering your system, then turn off the air conditioner. Remove visible signs of moisture with rags or a wet vacuum, then clean the infested area with AC-safe mold and mildew products. You can also take an extra step in preventing their future growth by installing mold-reducing filters or even an ultraviolet light.
