Many homeowners think power surges only happen during lightning storms. While lightning is one cause, it’s certainly not the only one. Utility grid activity, restoring power after outages and large household appliances cycling can all create electrical surges inside your home. 

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

What Is a Power Surge  

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

Lightning is the most well-known cause, but many electrical surges begin 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. Large appliances like refrigerators or HVAC systems can also create minor voltage fluctuations when they cycle on and off. Sometimes, loose wiring or other home electrical issues contribute to surges. 

Though a single significant surge can cause immediate damage, smaller surges can slowly wear down HVAC components over time, limiting their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Many of today’s heating and cooling systems use high-tech electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they can make equipment more sensitive to voltage spikes, increasing the importance of HVAC electrical protection. 

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

  • Control boards. They function as the system’s control center and can be damaged by even very small voltage spikes. 
  • Energy-efficient variable-speed motors. Variable speed motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that communicate with your HVAC equipment. 
  • Electronic communication systems. Modern heating and cooling systems use electronic communication between indoor and outdoor units for reliable operation. 
  • Variable-capacity inverter technology. Systems with variable-capacity operation use sophisticated electronics that work best with surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

Damage from electrical surges can cost hundreds or even thousands of dollars to fix. Installing whole-home surge protection helps reduce the risk of unexpected failures and costly HVAC repair after electrical surge incidents. 

HVAC components most commonly affected by power surges in Weatherford include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • 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 used to move conditioned air throughout your home. 
  • HVAC system capacitors. Power surges may weaken or damage these components, impacting system startup and performance. 
  • Thermostats and Smart Home Technology. These devices may malfunction after multiple voltage spikes. 
  • Heat pumpelectronics. Heat pump systems depend on multiple electronic components that are particularly 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 heating and cooling system. For HVAC system protection, whole-home surge protection offers greater coverage and lasting value. 

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

Benefits of Whole-House Surge Protection 

Adding 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-house HVAC surge protection include: 

  • Fewer repair costs. Preventing surge damage can help prevent expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. Electronic HVAC components experience reduced electrical stress over time when protected correctly. 
  • Home electronics protection. In addition to protecting your HVAC, whole-home surge protection also shields appliances, computers and entertainment systems. 
  • Less stress during storms. Homeowners gain added confidence when weather-related power outages occur. 
  • Defense against everyday electrical fluctuations. Minor electrical surges can gradually damage your HVAC system. 

5 Signs It’s Time to Consider Surge Protection 

  1. Severe weather. Given the strong summer storms in Weatherford, lightning protection for your HVAC can help minimize the risk of surge-related damage. 
  2. Power outages or flickering lights. Ongoing power interruptions and electrical fluctuations increase the likelihood of power surges. 
  3. Aging electrical systems. Old wiring or substandard electrical equipment can add to your home’s surge risk. 
  4. High-efficiency HVAC equipment. Safeguarding 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 devices. Homes with smart thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

Yes. Installing whole-home surge protection is often a smart 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, and it helps extend the life of your home comfort system.

Yes. A power surge can damage your AC unit’s compressor, circuit board and blower motor, leading to costly repairs. AC surge protection helps protect your air conditioner from power surges by preventing the surges from reaching sensitive HVAC components.

Power surges are most commonly caused by lightning strikes, utility grid switching, power outages, power restoration and large appliances cycling on and off. Another possible cause is problems within your home’s electrical system. Repeated minor power surges can gradually wear down HVAC components over time.

A whole-house surge protector usually lasts 5 to 10 years, although that depends on the number and severity of the surges it absorbs. Surge protector systems in homes that experience many severe storms or utility power fluctuations may require replacement sooner.

In some cases, but not all. Homeowners insurance sometimes 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.

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