What maintenance action can help reduce the risk of mold growth in an HVAC system?

• A. Increasing humidity levels indoors
• B. Regular cleaning of condensate drain pans
• C. Leaving air filters unchanged for extended periods
• D. Limiting airflow in the ducts

Answer: (B)

Regular cleaning of condensate drain pans is crucial in reducing the risk of mold growth in an HVAC system. When moisture accumulates in condensate drain pans, it creates an ideal environment for mold and mildew, which thrive in humid conditions. If these pans are not cleaned, stagnant water can remain, fostering mold development. By routinely cleaning the drain pans, any potential for standing water is removed, significantly lowering the likelihood of mold growth in the system. This proactive maintenance helps ensure a healthier indoor air quality and prolongs the efficiency and longevity of the HVAC system.
