Does Rain Damage My Heating System Over Time?

AC Maintenance on rain damage Many people want to know if the rain and weather can damage an HVAC unit. Fortunately, your heating and cooling system is specially designed to handle moisture and extremes of temperature all year long. That means the weather is unlikely to cause any significant problems that regular maintenance can’t prevent. However, there are a few issues you should keep in mind to keep your HVAC system running safely.


Severe hail can cause damage to just about everything you own. If you expect a hail storm you should find some way to shelter an outdoor unit. Covering it with a free-standing wooden shelter might be the best solution. Do not use a tarp or plastic bag that will block ventilation.


Instances of flooding where 15 inches or more of rain accumulates can damage your HVAC system. Sandbag barriers may prevent some damage. If your system is properly insulated, there is a chance it will not be damaged. However, electrical hazards can pose a serious threat to your safety. If your unit has endured severe flooding, it’s best to have it inspected by a heating and cooling professional.


If your outdoor unit becomes covered with snow, the vents can become blocked. That can cause damage if you attempt to operate it in that condition. If snow does cover your HVAC unit, simply clear it away before use. You may need to have it inspected for flood damage.


Falling tree limbs and other windblown debris are always dangerous and can damage your unit. Ordinarily, it would take a very strong wind to damage an HVAC unit in the absence of debris impacts. If your unit has been struck by heavy debris or rocked off of its foundation by a powerful wind, you should have it inspected by a professional before continued use.
