Mold: A Common HVAC Complaint That Is Easy To Deal With

The presence of mold in an HVAC system is a common complaint.  Mold is a sneaky little bugger.  It can grow and proliferate and make building occupants sick without ever being seen.   And the fastest way to spread mold through a building is through a forced-air HVAC system.

The reason this complaint is so common is that mold is always present in your buildings and your HVAC system if it is present in your building’s environment.   There will be more mold in humid weather and less in dry weather.   You will never get rid of it completely, but you can control it.   All it needs to grow is moisture and food.   Take those away and the mold goes away.

According to the U.S. EPA, routinely inspect your HVAC systems, not just for mold, but for moisture.   Look at the drain and condensate pans to make sure they are draining properly.   If we plug them?!, the moisture that accumulates will become a mold factory.  Also make sure that all HVAC ducts and system components such as air handlers, blowers, plenums are free of any moisture.

If, despite regularly inspecting your system, you are still getting complaints about it (mold grows in as little as 48 hours), here are some tips you can share with your HVAC contractor for cleaning it up:

 

1.) Turn off your HVAC system.

2.) Everyone involved in this cleaning should wear at least an N-95 respirator.

3.) Replace anything porous, such as filters or insulation that has become wet.  Double-bag the waste using at 6-mil or thicker plastic bags.

4.) Use wet vacuums to clean out any standing water.

5.) Use an EPA registered disinfectant labeled for HVAC used to clean non-porous surfaces (Ductwork, coils, plenums, pans, etc.) of mold, mildew, and other dirt. BBJ MMR-II ready-to-use disinfectant and mold cleaner will kill and remove mold, mildew and odor-causing bacteria.

6.) As an added measure, isolate each section of ductwork you clean with bladders so the spores you stir up during cleaning don’t spread to other parts of the system or the building. Fog the area with an EPA registered disinfectant.

7.) Apply a mold and mildew inhibitor to all components of the HVAC systems. Again, this must be EPA registered and specifically labeled for HVAC systems to limit risks associated with using the wrong chemicals and cleaners in HVAC systems. Excellent way Coil Shine-BC is EPA registered for HVAC systems to control mold growth for up to 2 years.

8.) As the last step, HEPA vacuum anything that you cleaned up.
