How Rain Can Damage Your Heating System

Light to moderate rainfall usually doesn’t cause damage to your heating system. Heavy rainfall, however, may damage internal components of the unit and cause a health hazard for your family. Some of the most common issues caused by rain include mold and mildew, corrosion of internal components and flooding.

Mold and Mildew

Excessive rain, floods, and snow melting inside the HVAC system can lead to mold and mildew growth. You should never leave over an inch of snow sitting on top of the unit. When water gets inside of the heating system and ventilation is poor, mold and mildew can develop. Mold and mildew are damaging to your health, so it’s important to call an HVAC repair company for an inspection if you suspect these fungal growths.

Warning signs your heating system may have mold include:

  • Musty odors when the heat runs
  • Puddles around the HVAC system
  • Mold on the outside of the unit
  • Frequent coughing or sneezing

Corrosion of Internal Components

When the heating system isn’t covered or vented correctly during heavy rain, internal components can begin to corrode from the water damage. Don’t place a heavy tarp over the unit as this is a common mistake people make that cuts off ventilation. You can contact Air Comfort of KY in Louisville, KY, for heating maintenance service. During maintenance, we’ll clean the internal components and replace parts that are no longer working.

Flood Damage

Heavy rain sometimes causes flooding, which is one of the most obvious causes behind damage to the heating system. We advise contacting an HVAC company if flood waters got to your unit. Even if your heating system seems to work correctly, you don’t know if mold is developing inside. Other problems that flooding can cause include pest infestations, damaged wiring, and clogs. These issues might not immediately shut down your heating but they eventually can.
