Many homeowners think power surges only happen during lightning storms. Although 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 electrical surges inside your home. 

These electric voltage spikes don’t just pose a risk to televisions and computers. They may also cause HVAC electrical damage because modern heating and cooling systems rely on advanced electronic components. The good news is HVAC surge protection can help shield 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 sudden spike in electrical voltage running through your home’s wiring. Although it lasts only a fraction of a second, it can damage household electronics, including HVAC equipment. 

Many people know lightning is the most well-known cause, but many electrical surges begin much closer to home. Utility companies regularly switch power on the electrical grid, and electrical surges also can happen when electricity is restored after an outage. Large appliances like refrigerators or HVAC systems can also create brief voltage fluctuations when they cycle on and off. Sometimes, loose wiring or other home electrical issues contribute to surges. 

Although one major power surge can cause immediate damage, smaller surges can slowly wear down heating and cooling equipment over time, limiting their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Many of today’s heating and cooling systems use sophisticated electronics to improve comfort and energy efficiency. Even though hese advanced features offer many benefits, they also make equipment more vulnerable to damage from voltage spikes, increasing the importance of HVAC electrical protection. 

HVAC parts that are especially sensitive to power surges include: 

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

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components most vulnerable to power surges in Highlands Ranch include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • HVAC compressors. An HVAC compressor is one of the costliest parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors responsible for circulating conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, affecting system startup and performance. 
  • Smartthermostats. Electronic thermostats can malfunction after frequent 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 people use surge-protecting power strips for computers and televisions, but power strips don’t protect your HVAC system. To provide complete HVAC system protection, whole-home surge protection offers broader coverage and greater long-term value. 

A professionally installed whole-house surge protector is set up right at your home’s electrical panel. Unlike devices that protect only one outlet, it helps safeguard major appliances and electronics throughout the house, including your heating and cooling equipment. 

Benefits of Whole-Home Surge Protection 

Installing whole-home surge protection is a smart way to protect your HVAC investment while helping safeguard other valuable electronics throughout your home. 

Benefits of whole-home HVAC surge protection include: 

  • Reduced repaircosts. Preventing surge damage can help reduce expensive HVAC repairs. 
  • Extended HVAC system lifespan. Electronic HVAC components experience less electrical stress over time when equipped with surge protection. 
  • Protection of homeelectronics. In addition to protecting your HVAC, whole-home surge protection also shields appliances, computers and entertainment systems. 
  • Added confidence during severe weather. Homeowners gain added confidence when severe weather strikes. 
  • Protection from everyday electrical fluctuations. Small voltage spikes can gradually damage electronic HVAC equipment. 

5 Signs You May Need Surge Protection 

  1. Severe weather. Given the strong summer storms in Highlands Ranch, lightning protection for your HVAC can help minimize the risk of electrical surge damage. 
  2. Frequent power outages or flickering lights. Frequent outages and changing voltage levels increase the likelihood of damaging voltage spikes. 
  3. Aging electrical systems. Old wiring or obsolete electrical equipment can increase your home’s surge risk. 
  4. High-efficiency HVAC equipment. Shielding a high-efficiency heating and cooling system by installing whole-home surge protection is often more affordable than repairing or replacing damaged components. 
  5. Smart home technology. Homes with connected thermostats and other connected devices have more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Yes. Installing whole-home surge protection is often worth the investment because it helps protect expensive HVAC equipment. The cost of installing surge protection is typically much lower than repairing or replacing damaged HVAC components, helping extend the life of your home comfort system.

It can. A power surge can damage your AC unit’s compressor, circuit board and blower motor, resulting in major repairs. Installing AC surge protection can protect your air conditioner from electrical fluctuations by preventing the surges from reaching 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.

Most whole-home surge protectors last 5 to 10 years, although actual service life 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.

In some cases, but not all. Homeowners insurance can cover power surge damage, but coverage depends on your policy and what caused the surge. With policy limits and deductibles varying, surge protection installation is often a smart way to help prevent expensive HVAC repairs.
