How Power Surges Can Damage Your HVAC System and What You Should Do About It

October 14, 2024

We often take our HVAC systems for granted—until they stop working. In Florida, where air conditioning is essential, power surges can cause serious problems with your cooling system. These surges can lead to sudden repairs, expensive replacements, and days of discomfort in the heat. Homeowners need to understand how power surges impact their HVAC systems and when to call experts like Elevate Home Services to save time and money.

What Is a Power Surge?

A power surge occurs when there’s a sudden spike in voltage, which can happen due to events like lightning strikes, issues with the power grid, or faulty wiring. While homes are built to handle a specific voltage range, surges can far exceed that, damaging your electronics and appliances—especially your HVAC system.

How Do Power Surges Affect HVAC Systems?

Your HVAC system, like other modern electronics, relies on complex electrical components, making it vulnerable to power surges. Here’s how a surge can cause problems with your air conditioning:

  1. Circuit Board Damage: The circuit boards that control your system’s functions are susceptible to surges, and if they’re fried, your system may stop working.
  2. Compressor Issues: The compressor is a key (and costly) component in your cooling system. A surge can cause it to overheat or malfunction, leading to a breakdown.
  3. Thermostat Failure: Surges can disrupt the electronics in your thermostat, resulting in incorrect temperature readings or a complete system shutdown.
  4. Blown Capacitors: Capacitors help start and keep your HVAC running smoothly. A surge can blow a capacitor, preventing your system from working properly.

Signs Your HVAC System Has Suffered a Power Surge

It’s not always obvious when a power surge has affected your air conditioning system. However, there are a few signs to watch for:

  • The system doesn’t turn on after a storm or power outage.
  • It cycles on and off more frequently than usual, which could be due to electrical damage.
  • You hear buzzing or humming sounds when the system is running.
  • The thermostat gives incorrect temperature readings or becomes unresponsive.

What Should You Do if a Power Surge Affects Your HVAC System?

If you suspect a power surge has damaged your HVAC system, the safest step is to contact Elevate Home Services. Trying to handle electrical repairs on your own can lead to more damage or even injury. Our team of trained professionals can assess the situation, make any necessary repairs, and recommend solutions to prevent future surges from impacting your system.

Preventing Power Surge Damage

While you can’t completely stop power surges, there are a few ways to reduce the risk of damage to your HVAC system:

  1. Install a Whole-House Surge Protector: This device helps protect your home’s electrical system—including your HVAC—from power surges.
  2. Use a Dedicated HVAC Surge Protector: This smaller surge protector connects directly to your air conditioning system for an added layer of protection.
  3. Regular HVAC Maintenance: Keeping your system well-maintained makes it better equipped to handle minor electrical issues, and routine checkups can help spot potential problems early.

John M.

As being a retired electrical contractor since 1980 and real estate investor, I was impressed, they gave me next day service, called me when in route, called me when completed, and billing was more than fair, unlike those companies that do flat rates.

Jerry S.

From the office personnel to the installation. The office staff were courteous and professional, Josh, the salesman, was here the next day and gave me a quote right away that was very fair and, I think, quite competitive. Joe and Reuben, the installers, came two days later to do the installation. They were very knowledgeable, courteous and professional and did a fantastic job. They represented your company extremely well. I love the Bryant package unit, recommended by Josh, it's attractive, efficient and quiet. Thanks to all.

Glen C.

We have been a client for just over 10 years and I’m very happy with their service, workmanship and pricing. In this day and age, it’s hard to find a company that you can’t find fault with, but this is one of them.

Don N.

We’ve dealt the the Griffith company for 20 years and Larry made us feel comfortable with the merging of companies that is happening. We are looking forward to having our new AC installed and the continuing excellence of service we’ve experienced from this company over the years.
