Prevent Lightning Damage from Ruining Your HVAC Unit

Prevent Lightning Damage from Ruining Your HVAC Unit

While some parts of the country prepare for ice and snow, we here in Jacksonville are hanging tight while battling tropical thunderstorms. A little bit of rough rain isn’t necessarily a big deal, but what comes with it can be – particularly for HVAC units. Thunderstorms often bring lightning strikes to our area and those bolts can wreak havoc on heating and air conditioning units.

When lightning zaps an electrical source, it can send the standard voltage into high stratosphere. This pushes the voltage to spike beyond its capacity, causing power surges that can easily short an HVAC unit. While you may not be able to stop the forces of nature, there are steps you can take to help prevent or minimize lightning damage.

Install Surge Protectors

One of the simplest things you can do is to install surge protectors at crucial spots in the electrical wiring system. This not only helps to protect your HVAC unit, it may also prevent or minimize damage for other major electrical outfits on your property.

Check the Grounding System

Making sure your electrical system is properly grounded is the first step toward preventing lightning from damaging your HVAC unit. Search for any signs of wear-and-tear, such as corrosion. Look around for any loose wiring or threads. If you can, try to detect any wayward surging in the overall system. If you need help, a qualified electrical contractor can do it for you.

Watch Those Bonds and Routing

Effective wiring systems operate more smoothly when its grounding electrodes are properly bonded. Think of it as a strategic map; the more secure the connecting electrodes are, the better your wiring system will be grounded and protected against power surges.

Electrodes routed through different wiring paths may not work together to establish proper grounding and solid grounding is was helps prevent power surges. If there is faulty or insecure electrode bonding, it can leave your HVAC unit wide open to lightning-based damage. It is not unusual to find faulty electrode connections in a wiring system either. That’s part of why it is so important to check these connections or have a professional do it for you.

Check Cable Connections Throughout the Property

If you have a garage or another space that utilizes the same cable connection as the main property, it could provide an inconvenient pathway for a power surge to travel over there and do some damage. Cables are often insulated with conductive material and this conductivity is also a highway for higher-than-average voltage. Make sure any connective cables are surge-resistant. If not, look into having the cables modified to prevent any surges from going haywire and hitching a ride to other spaces.

Schedule an Inspection

Regular maintenance is also preventative maintenance. So, give some serious consideration to scheduling an annual electrical inspection. Tropical storms aren’t particularly predictable, but you probably have a solid idea of when hurricane season is on the way. Reach out to a qualified company and have them look things to help keep lightning damage at bay.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople.

Again, no pressure, just helped with our follow up questions.
