A » A musty smell from your HVAC system often indicates mold or mildew growth, typically due to moisture accumulation within the system. This can occur in areas like the ductwork, evaporator coils, or drip pans. Regular maintenance, including cleaning and inspecting these components, can prevent mold growth and eliminate unpleasant odors. Additionally, ensuring proper ventilation and installing a high-efficiency air filter can help maintain air quality and system performance.
