Many people think power surges only happen during lightning storms. Although lightning is one cause, it isn’t 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. These surges can cause HVAC electrical damage because today’s heating and cooling systems rely on highly sensitive electronic components. Thankfully, HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of costly repairs. 

What Is a Power Surge  

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

Lightning is the most well-known cause, but many surges happen 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. Major appliances like refrigerators or HVAC systems 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. 

Although one major power surge can cause immediate damage, repeated minor surges can slowly wear down HVAC components over time, limiting their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

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

HVAC parts that are especially sensitive to power surges include: 

  • Circuit boards. They function as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Energy-efficient variable-speed 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. 
  • HVAC system communication controls. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Variable-capacity inverter technology. Systems with variable-capacity operation use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most at Risk? 

Damage from voltage spikes can cost hundreds or even more to repair or replace. Installing whole-house surge protection helps minimize the risk of unexpected failures and expensive HVAC repair after power surge incidents. 

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

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • HVAC compressors. An HVAC compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors responsible for circulating conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, affecting system startup and performance. 
  • Thermostats and Smart Home Technology. These devices may malfunction after frequent voltage spikes. 
  • Heat pump control electronics. Modern heat pumps use multiple electronic components that can be vulnerable to surges. 

Whole-Home Surge Protection vs. Power Strips 

Homeowners commonly use surge-protecting power strips for computers and televisions, but those devices don’t protect your furnace or air conditioner. For HVAC system protection, whole-home surge protection offers broader coverage and greater long-term value. 

A professionally installed whole-house surge protector is connected 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 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-house HVAC surge protection include: 

  • Reduced repaircosts. Avoiding surge damage can help prevent expensive HVAC repairs. 
  • Extended HVAC system lifespan. Sensitive components experience less electrical stress over time when properly protected. 
  • Home electronics protection. In addition to protecting your HVAC, a whole-home surge protector also helps protect appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Homeowners gain added confidence when severe weather strikes. 
  • Defense against everyday electrical fluctuations. Small voltage spikes can gradually damage connected HVAC devices. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the frequent summer storms in Skokie, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Blackouts or flickering lights. Ongoing power interruptions and changing voltage levels increase the likelihood of electrical surges. 
  3. Older electrical systems. Old wiring or substandard electrical equipment can raise your home’s surge risk. 
  4. Expensive HVAC equipment. Safeguarding a high-efficiency heating and cooling system with a surge protector is often less expensive than repairing or replacing damaged components. 
  5. Smart home technology. Homes with Wi-Fi thermostats and other connected devices have additional sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

Yes. Whole-home surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. The cost of installing surge protection is typically much lower than repairing or replacing damaged heating and cooling components, and it helps extend the life of your home comfort system.

Absolutely. A power surge can damage an air conditioner’s compressor, circuit board and blower motor, which can cause major repairs. AC surge protection helps protect your air conditioner from electrical fluctuations 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. Even small, repeated surges can gradually wear down HVAC components over time.

A whole-house surge protector usually lasts 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 need replacement sooner.

It can. 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 cost-effective way to protect your pocketbook from expensive HVAC repairs.

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