Homeowners often think power surges occur only during lightning storms. While lightning is one cause, it’s certainly not the only one. Utility switching, power outages/restoration and even large appliances cycling on and off can all create power surges inside your home. 

These electrical surges don’t just threaten televisions and computers. They can also cause HVAC electrical damage because modern heating and cooling systems rely on advanced electronic components. Thankfully, HVAC surge protection can help safeguard one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Is a Power Surge  

A home power surge is a short spike in electrical voltage in your home’s wiring. While it lasts only a fraction of a second, it may damage electronic components. 

Many people know lightning is the most well-known cause, but power surges often occur much closer to home. Power companies frequently adjust power on the electrical grid, and power can also surge when electricity is restored after an outage. Household appliances like refrigerators or AC units can also create small voltage fluctuations when they cycle on and off. It’s also possible that loose wiring or other home electrical issues lead to surges. 

While a single large surge can cause immediate damage, repeated minor surges can slowly wear down heating and cooling equipment over time, limiting their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Today’s heating and cooling systems use high-tech electronics to improve comfort and energy efficiency. While these features offer many benefits, they can also make equipment more vulnerable to damage from voltage spikes, highlighting the importance of HVAC electrical protection. 

Some of the most at-risk HVAC components to power surges include: 

  • Control boards. They serve as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Variable-speed blower motors. These advanced motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that communicate with your HVAC equipment. 
  • Communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for efficient operation. 
  • Variable-capacity inverter technology. Variable-capacity HVAC systems use sophisticated electronics that benefit from surge protection. 

Which HVAC Components Are Most at Risk? 

Damage from voltage spikes can cost hundreds or even thousands of dollars to fix. Installing electrical surge protection helps reduce the risk of unexpected failures and expensive HVAC repair after voltage spike incidents. 

HVAC components most vulnerable to power surges in McPherson include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Airconditioner compressors. The compressor is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors that circulate conditioned air throughout your home. 
  • HVAC system capacitors. Surges can weaken or damage these components, affecting system startup and performance. 
  • Smartthermostats. These devices may malfunction after multiple voltage spikes. 
  • Heat pumpelectronics. Heat pump systems depend on multiple electronic components which are vulnerable to surges. 

Whole-Home Surge Protection vs. Power Strips 

Many homeowners use surge-protecting power strips for computers and televisions, but power strips don’t protect your HVAC system. For HVAC system protection, whole-home surge protection offers greater coverage and lasting value. 

A professionally installed whole-home surge protector is set up right at your home’s electrical panel. Instead of regulating electricity to only one outlet, it can help safeguard major appliances and electronics throughout your house, including your heating and cooling equipment. 

Benefits of Whole-Home Surge Protection 

Using whole-home surge protection is an effective way to protect your HVAC investment while also helping safeguard other valuable electronics throughout your home. 

Benefits of whole-home HVAC surge protection include: 

  • Reduced repaircosts. Preventing surge damage can help avoid expensive HVAC repairs. 
  • Extended HVAC system lifespan. vulnerable technological components experience lower electrical stress over time when properly protected. 
  • Home electronics protection. In addition to protecting your HVAC, whole-home surge protection also safeguards appliances, computers and entertainment systems. 
  • Added confidence during severe weather. Homeowners gain added confidence when severe storms strike your area. 
  • Protectionagainst everyday electrical fluctuations. Even small, routine surges can gradually damage connected HVAC devices. 

5 Signs You May Need Surge Protection 

  1. Regular summer storms. Given the powerful summer storms in McPherson, lightning protection for your HVAC can help reduce the risk of power surge damage. 
  2. Power outages or flickering lights. Repeated outages and changing voltage levels increase the likelihood of damaging voltage spikes. 
  3. Older electrical systems. Old wiring or outdated electrical equipment can add to your home’s surge risk. 
  4. Modern heating and cooling equipment. Protecting a high-efficiency heating and cooling system with a surge protector is often far less costly than repairing or replacing damaged components. 
  5. Connected home technology. Homes with smart thermostats and other connected devices have additional sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

In most cases, yes. Whole-home surge protection is often worth the investment because it helps protect expensive HVAC equipment. Installing surge protection is typically much lower than repairing or replacing damaged HVAC components, and it helps extend the life of your home comfort system.

It can. A power surge can damage an air conditioning compressor, circuit board and blower motor, which can cause expensive repairs. A surge protector for your AC helps protect your air conditioner from electrical surges by shielding the sensitive HVAC components.

The most common sources of power surges include lightning strikes, utility grid switching, power outages, power restoration and large appliances cycling on and off. Power surges may also stem from problems within your home’s electrical system. Even small, repeated surges can gradually wear down HVAC components over time.

A typical whole-home surge protector lasts about 5 to 10 years, although its lifespan depends on the number and severity of the surges it absorbs. Surge protector systems in properties that experience frequent storms or utility power fluctuations may need replacement sooner.

In some cases, but not all. Homeowners insurance sometimes cover power surge damage, but coverage depends on your policy and what caused the surge. Since coverage and deductibles differ, surge protection installation is often cost-effective way to protect your pocketbook from expensive HVAC repairs.

It can. Power surge protection for HVAC helps safeguard smart thermostats and other connected HVAC components from damaging voltage spikes. It also helps improve system performance and reduce the risk of expensive repairs to home heating and cooling equipment.
