Surge Protection for Your HVAC Unit

Here in the Tennessee Valley, we’re used to severe weather. Fall and spring, especially, the storms come rolling in, and between the wind and the lightning, we inevitably end up dealing with power outages and downed power lines, and the power surges that go with them. Even worse, sometimes the lightning strikes nearby, causing a particularly massive surge.

Although we think of lightning and power outages as the main causes of power surges, it’s important to note that smaller fluctuations in the power grid happen much more often. These smaller fluctuations can be caused by routine, everyday occurrences as simple and unavoidable as major appliances turning on and off. While these weaker surges don’t have the dramatic effects of a lightning strike, both weak and strong surges can cause damage to the electrical devices in our homes.

Many of us use surge protectors to guard our electronic devices like computers and televisions, but not everyone realizes that HVAC systems need surge protection, too. Without that protection, even very weak, everyday power surges can cause damage to the electrical components of an HVAC unit, particularly the capacitor. That damage may not be immediately obvious because the system continues to run. However, over time that minor damage can lead to much larger and more expensive problems, even shortening the lifespan of the HVAC unit.

Of course, stronger power surges can cause immediate, major damage such as compressor failure. Damage like this may cost thousands of dollars to repair or may even require replacing the entire system. While no surge protector can save your HVAC from a direct lightning strike, it can do a lot to protect your investment against damage from the more common threats like nearby strikes and surges caused by power outages.

We can’t just buy a surge protector for our HVAC unit at the store and plug it in like we do with our smaller electronic devices, but we can get a professional to install surge protection quickly and easily and for a very low cost compared to the price of making major repairs or replacing the entire system. Surge protection can even be tailored to your needs and budget, protecting specific parts of your HVAC such as the motor, compressor, or electrical components.

So ask yourself–when storms come rolling in, wouldn’t you like to know that your HVAC system is protected?
