Can Rain Damage My Heating System?

Damage to your heating system doesn’t occur under ordinary conditions, such as normal rainfall or other light precipitation. The danger to your heating system comes when it’s wet for long periods of time.

For example, ordinary snowfall won’t damage your heating system. However, if snow accumulates on your heating unit and stays there for days, the internal wiring can be affected, leading your heating system to overheat.

You may be tempted to place a tarp over the external element of your heating unit during rainy weather. This is ill-advised because it limits airflow. Your system could freeze or overheat.

Extreme Weather

Your heating system can be damaged by extreme weather events such as blizzards, hurricanes, and hailstorms. Don’t be concerned about random bursts of small hail. Instead, protect your heating system from long periods of icy rain and large hailstones. Key indicators of damage to your heating system include reduced air flow and pressure, an odd smell, strange noises or a drop in hot air production.

While maintenance and service checkups can mitigate this damage, your heating system may need repairs after prolonged severe weather conditions. At Prime Comfort in Charlotte, NC, we know all about repairing damage to heating systems after hurricanes.


Hurricanes and prolonged heavy rain can sometimes lead to flooding. If your heating system becomes completely soaked, contact Prime Comfort as soon as it’s safe to do so. Your heating system could be at risk for complete operational failure if it can’t dry out.

Perpetually wet heating units are prone to insect infestations, mold, clogged filters, and destroyed wiring. After our technicians perform a thorough inspection of your unit, we’ll advise you as to whether it requires maintenance, a repair or complete replacement.
