Can My HVAC Get Damaged By Thunderstorms?


Protect your heating and air conditioning equipment with one simple device.

Is it safe to run heating and air conditioning equipment during a thunderstorm? The answer might surprise you. Electricity attracted to your home will create a powerful surge capable of wiping out all your electronics, HVAC included. Thankfully, there are a few ways you can protect your home's defense against discomfort.

Surge Protectors

Surge protecting power strips became popular with the rise of the home computer. Now, they're as common as a light switch. The problem is finding one large enough to handle the impact of a lightning strike. You can find whole-home surge protectors capable of securing everything from the refrigerator to the cellphone. Others are just for your HVAC system.

Suspend Use During Storms

Another, more straightforward method of protecting your HVAC equipment during a thunderstorm is simply to turn it off until the storm is over. You don't have to do anything special to stay safe. Unfortunately, this method leaves a lot to chance, as lightning can still strike your HVAC unit directly.

The only break you get is knowing things cool down during a thunderstorm, so the heat and humidity shouldn’t be overwhelming. Running your HVAC equipment during a rainstorm without lightning is safe as well, though it can be hard to predict when lightning will happen.

Damage from Thunderstorms

Homeowners are sometimes shocked to a learn a lightning strike to your home can create a surge powerful enough to destroy all kinds of equipment. Computers and other home electronics, washers, dryers and refrigerators, and yes, even AC units, are sometimes useless after a storm hits. It pays to work with an HVAC provider who can help you protect your home.
