Homeowners often think power surges only happen during lightning storms. While lightning is definitely one cause, it isn’t 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 threaten televisions and computers. They can also cause HVAC electrical damage because today’s heating and cooling systems rely on advanced electronic components. The good news is HVAC surge protection can help safeguard one of your home’s biggest investments and reduce the risk of major repairs. 

What Is a Power Surge  

A home power surge is a brief spike in electrical voltage in your home’s wiring. Even though it lasts only a fraction of a second, it still can 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 voltage can also spike when electricity is restored after an outage. Household appliances like refrigerators or air conditioners can also create minor voltage fluctuations when they cycle on and off. It’s also possible that loose wiring or other home electrical issues lead to surges. 

Though a single significant surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and air conditioning systems over time, reducing their lifespan. 

Why Modern HVAC Systems Need More Surge Protection 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 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: 

  • Control boards. They serve as the system’s control center and can be damaged by even brief or small voltage spikes. 
  • Variable-speed motors. Variable speed motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Smart home devices are made with delicate electronics that automatically adjust your HVAC equipment. 
  • Electronic communication systems. Many newer heating and air conditioning systems use electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter-driven technology. Variable-capacity HVAC systems use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Need the Most Protection? 

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

HVAC components that are frequently damaged by power surges in Norco and surrounding parishes include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Airconditioner compressors. The 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. Surges can weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. Electronic thermostats can malfunction after multiple voltage spikes. 
  • Heat pumpelectronics. 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? 

Homeowners commonly use surge-protecting power strips for computers and televisions, but those devices don’t protect your heating and cooling system. To provide complete HVAC system protection, whole-home surge protection offers greater coverage and lasting value. 

A professionally installed whole-home surge protector is located at your home’s electrical panel. Rather than protecting only one outlet, it helps safeguard major appliances and electronics throughout your house, including your HVAC system. 

Benefits of Whole-House Surge Protection 

Installing whole-home surge protection is an effective 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 reduce expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Sensitive components experience reduced electrical stress over time when properly protected. 
  • Protection of homeelectronics. In addition to protecting your HVAC, whole-home surge protection also safeguards appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. You’ll have added confidence when severe storms strike your area. 
  • Defense against everyday electrical fluctuations. Even small, routine surges can gradually damage electronic HVAC equipment. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the frequent summer storms in Norco and surrounding parishes, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Power outages or flickering lights. Frequent outages and voltage 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. Modern heating and cooling equipment. Protecting 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 HVAC Surge Protection 

Is a whole-house surge protection beneficial for an HVAC system? 

Absolutely. Whole-house 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 heating and cooling components, helping extend the life of your home comfort system. 

Can an electrical surge damage an AC unit? 

Yes. A power surge can damage an air conditioner’s compressor, circuit board and blower motor, which can cause costly repairs. A surge protector for your AC 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 in 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. Another possible cause is problems within your home’s electrical system. Repeated minor power surges can gradually wear down HVAC components over time. 

How long does a whole-home surge protector last? 

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 a homeowners insurance policy cover power surge repairs? 

It depends. Homeowners insurance may 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 protect your pocketbook from expensive HVAC repairs. 

Can surge protection help protect smart thermostats? 

Absolutely. Power surge protection for HVAC helps shield smart thermostats and other connected HVAC components from power surges. It also helps improve system reliability and reduce the risk of costly repairs to modern heating and cooling equipment.
