Homeowners often think power surges occur only during lightning storms. While lightning is one cause, it’s certainly not the only one.  Major appliances turning on and off, electrical grid switching, power outages and restoration can all create power surges inside your home. 

These electric voltage spikes don’t just pose a risk to televisions and computers. They can also cause HVAC electrical damage because today’s heating and cooling systems rely on highly sensitive electronic components. The good news is 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 sudden spike in electrical voltage in your home’s wiring. Although it lasts only a fraction of a second, it can damage electronic components. 

Many people know lightning is the most well-known cause, but many electrical surges begin 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 HVAC systems can also create small voltage fluctuations when they cycle on and off. In some cases, loose wiring or other home electrical issues contribute to surges. 

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

Why Modern HVAC Systems Are More Vulnerable Than Ever 

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

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

  • Circuit boards. They function as the system’s control center and can be damaged by even brief or small voltage spikes. 
  • Variable-speed blower motors. These energy-saving motors rely on electronic controls that are susceptible to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that communicate with your HVAC equipment. 
  • Communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter technology. Variable-capacity HVAC systems use 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 more to repair or replace. Installing whole-house 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 Beaverton include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Airconditioner compressors. An HVAC compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors that circulate conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, reducing system startup and performance. 
  • Thermostats and Smart Home Technology. These devices may malfunction after repeated voltage spikes. 
  • Heat pumpelectronics. Modern heat pumps use multiple electronic components that can be 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 more comprehensive coverage and long-term value. 

A professionally installed whole-home 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 HVAC system. 

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: 

  • Fewer repair costs. Avoiding surge damage can help reduce 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 shields appliances, computers and entertainment systems. 
  • Less stress during storms. You’ll have added confidence when severe storms strike your area. 
  • Protection from everyday electrical fluctuations. Small voltage spikes can gradually damage connected HVAC devices. 

5 Signs You May Need Surge Protection 

  1. Frequent storms. Given the powerful summer storms in Beaverton, lightning protection for your HVAC can help reduce the risk of power surge damage. 
  2. Frequent power outages or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of electrical surges. 
  3. Aging electrical systems. Old wiring or obsolete electrical equipment can raise your home’s surge risk. 
  4. High-efficiency HVAC equipment. Protecting a high-efficiency heating and cooling system with a surge protector is often more affordable 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 Whole-Home Surge protection for HVAC 

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

Yes. A power surge can damage an air conditioning compressor, circuit board and blower motor, which can cause expensive repairs. AC surge protection helps protect your air conditioner from power surges by reducing the impact of voltage spikes before they reach 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. Another possible cause is 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 actual service life 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.

It can. Homeowners insurance may cover power surge damage, but coverage depends on your policy and the reason for the surge. Since coverage and deductibles differ, surge protection installation is often a smart way to protect your pocketbook from expensive HVAC repairs.

Yes. Power surge protection for HVAC helps safeguard smart thermostats and other connected HVAC components from electrical surges. Surge protection may also improve system longevity and reduce the risk of expensive repairs to modern heating and cooling equipment.
