What You Need to Know About Biofilms in HVAC Systems

Given how your heating and air conditioning system is one of your biggest investments, you’ll want to make sure it can continue delivering the safe and reliable performance you’ve come to expect. One way to do that is to keep tabs on its condition, which includes checking the system for biofilms. But what exactly are biofilms, and how do you deal with them? J & M Air Conditioning & Heating, a trusted HVAC specialist, shares what you need to know.


What Are Biofilms?

These refer to microbial growth that occurs not just in nature but in homes and industrial environments as well. Anywhere that’s dark and humid can provide an ideal breeding ground for biofilms. These include HVAC systems, which are often exposed to excess moisture and fluctuating temperatures. When overlooked, biofilms can negatively affect the performance and energy efficiency of your HVAC system. Not only that, but they may also lead to poor indoor air quality, triggering allergies and respiratory issues.

How Do You Get Rid of Biofilms?

You’ll need to find them first. Biofilms often develop in the HVAC coils and condensate pans. Some EPA-registered antimicrobials can be applied to these components to eliminate the growth. But biofilms can also occur in the ductwork, dispersing harmful airborne particles all the while, making them a bit more challenging to get rid of. Scheduling a comprehensive duct cleaning service with a premier air conditioning company like J & M Air Conditioning & Heating should take care of the issue.

How Do You Keep Them From Coming Back?

It pays to be proactive instead of reactive when it comes to biofilms. There are preventive measures you can take to stop them from developing in the first place. For instance:

  • Schedule regular HVAC inspections and tune-ups with a trusted technician like J & M Air Conditioning & Heating.

  • Keep the air filters, HVAC coils, ductwork, and drain pans clean.

  • Invest in and run a whole-home air purifier.

  • Get rid of excess moisture in your home using ventilators or dehumidifiers.

  • Try to have UV lamps installed.
