Homeowners often think power surges only happen during lightning storms. While lightning is one cause, it’s far from the only one. Utility grid activity, restoring power after outages and large household appliances cycling can all create power surges inside your home. 

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

What Is a Power Surge  

A power surge in your home is a brief spike in electrical voltage running through your home’s wiring. While it lasts only a fraction of a second, it still can damage electronic components. 

Lightning remains the most well-known cause, but many surges happen much closer to home. Electric utility providers routinely switch 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 brief voltage fluctuations when they cycle on and off. In some cases, loose wiring or other home electrical issues can cause surges. 

Though a single significant surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and cooling equipment over time, limiting their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Today’s heating and cooling systems use sophisticated electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they can also make equipment more vulnerable to damage from voltage spikes, increasing the importance of HVAC electrical protection. 

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

  • Electronic circuit boards. They serve as the system’s control center and can be damaged by even brief or small voltage spikes. 
  • Variable-speed motors. These energy-saving motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that control your HVAC equipment. 
  • HVAC system communication controls. Modern heating and cooling systems use electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter technology. Systems with variable-capacity operation use sophisticated electronics that benefit from surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

Damage from power surges can cost hundreds or even thousands to repair or replace. Installing whole-home surge protection helps lower the risk of unexpected failures and expensive HVAC repair after power surge incidents. 

HVAC components that are frequently damaged by power surges in Derby include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • HVAC compressors. An HVAC compressor is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Electrical surges can damage motors responsible for circulating conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, reducing system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats can malfunction after multiple voltage spikes. 
  • Heat pump control electronics. Heat pump systems depend on multiple electronic components that can be vulnerable to surges. 

Which is Better for My Home: Whole-Home Surge Protection or Power Strips? 

Many homeowners use surge-protecting power strips for computers and televisions, but those devices don’t protect your heating and cooling system. For complete HVAC system protection, whole-home surge protection offers more comprehensive coverage and lasting value. 

A professionally installed whole-house surge protector is connected at your home’s electrical panel. Unlike devices that protect only one outlet, the system helps safeguard major appliances and electronics throughout your entire house, including your HVAC system. 

Benefits of Whole-Home HVAC Surge Protection 

Using whole-home surge protection is a proactive way to protect your HVAC investment while also working to safeguard other valuable electronics throughout your home. 

Benefits of whole-house HVAC surge protection include: 

  • Lower repair expenses. Avoiding surge damage can help prevent expensive HVAC repairs. 
  • Extended HVAC system lifespan. vulnerable technological components experience lower electrical stress over time when equipped with surge protection. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-home surge protector also safeguards appliances, computers and entertainment systems. 
  • Less stress during storms. You’ll have added confidence when weather-related power outages occur. 
  • Protectionagainst everyday electrical fluctuations. Minor electrical surges can gradually damage your HVAC system. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Regular summer storms. Given the frequent summer storms in Derby, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Power outages or flickering lights. Ongoing power interruptions and changing voltage levels increase the likelihood of electrical surges. 
  3. Aging electrical systems. Old wiring or substandard electrical equipment can increase your home’s surge risk. 
  4. Expensive HVAC equipment. Shielding a high-efficiency heating and cooling system by installing whole-home surge protection is often less expensive than repairing or replacing damaged components. 
  5. Connected home technology. Homes with smart thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Is HVAC surge protection a good investment? 

Absolutely. Whole-home surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. Compared with repair costs, installing surge protection is typically much lower than repairing or replacing damaged HVAC components, helping extend the life of your home comfort system. 

Can a power surge damage an air conditioner? 

It can. A power surge can damage an air conditioner’s compressor, circuit board and blower motor, resulting in expensive repairs. AC surge protection helps protect your air conditioner from electrical fluctuations by reducing the impact of voltage spikes before they reach sensitive HVAC components. 

What causes power surges throughout a home? 

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

What is the average lifespan of a whole-house surge protector? 

Most whole-home surge protectors last 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 require replacement sooner. 

Does homeowners insurance cover damage caused by power surges? 

It can. Homeowners insurance can cover power surge damage, but coverage depends on your policy and the reason for the surge. Because deductibles and coverage vary, surge protection installation is often a smart way to help prevent expensive HVAC repairs. 

Will surge protection help protect smart thermostats? 

It can. Power surge protection for HVAC helps protect smart thermostats and other connected HVAC components from electrical surges. It can also improve system lifespan and reduce the risk of extensive repairs to your home’s heating and cooling equipment.
