Mold in an AC Unit

Mold in your HVAC system can lead to serious health problems including asthma, pneumonia and bronchitis as well as lowering the efficiency of your unit. Preventing mold growth in your system is therefore important to ensure healthy and quality indoor environment, and efficiency in running your heating, ventilation and air conditioning equipment. The first step in this entails understanding the conditions that encourage mold growth.

Molds basically need water and the right temperature range to grow. One of the best ways of controlling mold in your HVAC unit is properly maintaining and servicing your unit on a regular basis. This is because poor maintenance of your system can provide an ideal breeding ground for the mold to grow and thrive. The key components that you need to pay keen attention to are:

Coils and Drain Pans

Condenser coils dehumidify air and make condensate water to drip into a drain pan before exiting through a deep seal trap. Stagnant water usually accumulates if the drain pan isn’t maintained properly creating a microbial habitat. Frequent cleaning of your coils and drain pans is therefore essential to prevent this.

Duct Linings

You should not allow your duct linings to become moist from water supply since this promotes microbial growth. Ensure that you employ the services of a professional HVAC contractor to drain and periodically treat your duct linings to prevent mold growth.

Outdoor Air Dampers

Dust, dirt and other debris support microbial growth which has a considerable negative effect on the quality of your indoor environment. Cleaning the outdoor air dampers on a regular basis can remove dust and other contaminants buildup. This enhances your indoor air quality as well as increasing the efficiency of your HVAC system.

Air Filters

Air filters should be replaced or cleaned on a regular basis, at least once per month. Doing this will significantly improve your indoor air quality while minimizing energy consumption. When your air filters are clean, you will not have a problem with asthma, allergies and respiratory problems usually caused by contaminants in your indoor space.


When dust, dirt and other contaminants accumulate on your ducts, this restricts airflow which results in inefficiency in running your HVAC system and allows for growth of microbes. You can prevent microbial growth in your ductwork by:

  • Minimizing dust, dirt and other debris build-up
  • Promptly repairing water damage and leaks
  • Keeping key components in your system dry
  • Cleaning coils and drain pans regularly
  • Undertaking proper filter maintenance
