Last Updated on: January 9, 2024

We’re all familiar with those storms that can sweep across the DC area and create some powerful lightning. And many people take precautions for their electronics with surge protectors, but they don’t give a second thought about their AC unit until the damage has been done. With any act of mother nature, there are times when you simply cannot predict the effects it will have, but there are a few ways that you can protect an AC unit from lightning strikes. Here we list the next steps that you should take.

Make sure the AC unit is turned off

When a lightning and thunderstorm begins, go ahead and turn your AC unit off at the thermostat so that it’s not running. It will be much more susceptible to a power surge if it’s turned on and using energy to work. However, if lightning directly strikes the AC unit, you’ll want to call SSI in right away to inspect it because a direct hit will do different damage versus a power surge.

Record the event on paper

Whether you believe your AC unit was affected by a power surge, or you saw that lightning directly hit it, record everything that happened because many insurance companies will pay for the damage if you can prove it. If you notice after a storm that other items in your house have been affected such as your microwave or a video game console, then there’s a chance that your unit needs attention too.

Have an expert check it out

The earlier you catch the damage from a power surge, the more money you’ll save in the long run. If you simply don’t know that your AC unit was harmed, then have an expert inspect it. There are some inexpensive elements that a surge can damage such as the capacitor, and you might not notice for weeks. But the longer the system runs, those small components will start to impact other working parts, and soon you’ll need more AC repairs that you anticipated.

If you think that your AC unit was affected by a power surge, we’ll provide you with an inspection to ensure it’s working in prime condition. We want your AC unit to work seamlessly once the storm has passed! Call our friendly and experienced team today at (703) 968-0606.
