Does Weather Damage My Heating System Over Time?

HVACWhile normal rainfall does not damage an HVAC system over time, heavy amounts of continuous rain, as well as other forms of water, will deteriorate the interior and exterior of a heating system with proper maintenance by professional HVAC technicians.


Flooding can severely impair the ability of a heating system to function properly. If your neighborhood has received over 10 inches in a short time, contact McFarland Indoor Comfort Systems today to schedule a thorough inspection of your unit. Excessively wet HVAC systems that cannot dry out for extended periods may suffer clogs, deteriorating wiring, insect infestations, and other problems potentially leading to operational failures.

Hail and Ice

While very short bursts of smaller than pea-sized hail won’t damage a heating system, longer bouts of bigger hail and icy rain will batter and possibly breach an unprotected HVAC system. However, what many people don’t know is that placing a heavy plastic tarp over an HVAC unit prevents air from flowing around the unit. Overheating or freezing up of the system could occur when HVAC units are too tightly covered.


Allowing snow to cover an heating unit for more than a couple of days allows moisture to constantly melt and drip over the interior motor and wiring. Leaving more than an inch of snow on your HVAC system may cause overheating of the unit even though the temperature is below freezing.
