Can Too Much Rain Hurt My HVAC System?

There is no doubt that Centre County has had an interesting Spring so far! Between the tornado last week and the heavy rains that seem to be never ending – this Spring won’t be forgotten any time soon.

It is not uncommon when storms or heavy rains arrive, to worry about our homes, including our heating and air conditioning systems.

The important thing to note is that these systems are designed to withstand the outdoor elements. However, there are a few things to pay attention to when inspecting your system after a storm.

Weather Related Hazards for HVAC Equipment

Storm Damage

One thing to look out for when a storm hits – is damage to your HVAC unit. If high winds were part of the storm, be sure to inspect your equipment. Look for physical damage from fallen trees or branches. Also, make sure to clear away all debris that landed on your equipment.


A high amount of rain won’t damage your HVAC system. However, if you live in a flood prone area and experience 15 inches of water or more around your equipment, make sure to have a technician do an inspection prior to starting the unit.

Preventative Measures

It makes sense to want to take preventative measures when you expect a high amount of rain. However, never cover your HVAC equipment with a plastic garbage bag or tarp. You might think you are protecting it, but instead you can cause more damage. The plastic will trap moisture inside and this leads to rust and corrosion.

If you are concerned that your system is not working properly due to the recent storms in the area, be sure to give PBCI-Allen a call today. We can help you determine if you need any repairs in order to prepare for the summer AC season.
