Biofilm forms when free-floating microorganisms adhere to a surface. In an HVAC system, coils and other moisture-filled areas where dirt and dust usually accumulate present an ideal breeding ground for microbial growth. In this post, a trusted HVAC repair and installation company discusses the effects of biofilm in your HVAC system and shares tips for preventing or eliminating it.
Effects of Biofilm
Biofilm is often found in industrial environments and can plague some mechanical systems. The buildup of slimy microorganisms in heating and air conditioning systems can affect the flow of heat across a surface. It can also contribute to the premature corrosion of the surface and the spread of bacteria, viruses and mildew throughout your living space.
How to Eliminate or Prevent Biofilm
- Keep your coils clean. It’s important to perform routine heating and cooling services to maintain the cleanliness and efficiency of your air handlers. When there’s a buildup of biofilm on the coils, the unit will require more energy to adequately heat or cool the interior space. Schedule a maintenance visit at least once a year so that contaminants won’t have the chance to accumulate and go directly into the air you breathe. Installing ultraviolet lights over the coils is another effective way to kill bacteria and other harmful organisms.
- Replace your air filters. Changing your air filters on a regular basis is essential for maintaining good indoor air quality. As a general rule, you should replace your filters every 30 days. Also, many disposable filters, like cotton-blend filters in cardboard frames, can become food for mold and bacteria over time, so it’s better to avoid these.
