How Do I Reduce Mold in My HVAC System?
Molds are part of the natural environment. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees, but indoors, mold growth should be avoided. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.

When humid air passes over chilled cooling coils, water condenses and drips through the coils into a collection pan, from which it continuously drains. Problems with these systems may occur when this water collects and becomes stagnant or blocked, either on the coils or in the drip pan. The pan will grow mold that can infect your home with dangerous mold spores very quickly. Problems also exist when the HVAC ducting contains microscopic mold spores that stay continually present and blow contaminants around the home or office often caused by mold in other parts of your home.
You can do 3 things to prevent mold growth in your system:
- Preventative maintenance will ensure that the collection pan under the indoor coil stays clean and clog-free. Click here to view our preventative maintenance program.
- Install ultraviolet lights next to the cooling coils to kill any mold or bacteria growing on the coils or collection pan.
- Keep your ductwork clean and use a high-efficiency filtration system to keep your entire HVAC system clean.
