Common Signs That Mold Is Growing in Your HVAC System


When it comes to issues that can befall your home’s HVAC system, mold is one problem with which you definitely need to be concerned. This is because it brings a whole host of problems along with it. Not only is mold difficult to detect until its later stages, if left unattended it can make your home’s interior look unappealing and even cause respiratory issues for you and your household members.

Here the trusted professionals of John Stevenson Plumbing, Heating & Air Conditioning, Inc. share the signs of mold growth in your heating and cooling system and what you can do about it.

Respiratory Symptoms

As stated before, mold spores can cause respiratory issues for you and the members of your household, especially children and the elderly. If you or someone else in your family is experiencing recurrent respiratory symptoms at home, it’s possible that your HVAC system has mold growth, which means you need to call in a professional to inspect the system immediately.

Musty Odor

Mold usually has a musty odor that can make your home smell old and generally unpleasant. Oftentimes, you’ll notice the smell become stronger as you continuously run your home’s air conditioning system, especially if the mold has spread to the air ducts. If you begin noticing a musty smell in your home, call a heating installation and repair professional immediately to have the system inspected and any mold removed.

Visible Signs

The mold that grows on HVAC systems looks like any other kind of mold you may find in your basement or in a neglected shower. If you begin to see patchy black spots on your HVAC system, this is a visual sign that there’s mold growth present which will have to be cleaned before it spreads further.

How to Get Rid of Mold

To remove mold from your HVAC system, you’ll need to give the unit a good cleaning. First, put on a mask to prevent the mold spores from entering your respiratory system, then turn the HVAC unit off. Next, use a rag or wet vacuum to remove any signs of moisture before using mold and mildew removal products to thoroughly clean the unit.

To prevent mold growth in the future, consider installing mold-reducing filters or ultraviolet lights in the system to sanitize the unit. If you aren’t comfortable with doing these steps on your own, you can always turn to John Stevenson Plumbing, Heating & Air Conditioning, Inc. to get the job done for you.

If the mold has reached extreme levels, however, you’ll need to hire a mold remediation expert to thoroughly clean your HVAC system.
