Homeowners often think power surges only happen during lightning storms. Although lightning is one cause, it isn’t 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 surges don’t just damage televisions and computers. These surges can cause HVAC electrical damage because today’s 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 Are Power Surges  

A home power surge is a brief spike in electrical voltage in your home’s wiring. While 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 electrical surges also can happen when electricity is restored after an outage. Major appliances like refrigerators or AC units 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. 

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

Why Modern HVAC Systems Require Better Surge Protection 

Modern 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 sensitive to voltage spikes, increasing the importance of HVAC electrical protection. 

Some of the most vulnerable components to power surges include: 

  • Electronic circuit boards. They function as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Variable-speed blower motors. These advanced motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Smart home devices are made with delicate electronics that control 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 work best with surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components most commonly affected by power surges in Menomonie and western Wisconsin include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Airconditioner compressors. This component is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors used to move conditioned air throughout your home. 
  • HVACcapacitors. Power surges may weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. Electronic thermostats can malfunction after frequent voltage spikes. 
  • Electronic heat pump components. Heat pump systems depend on multiple electronic components that can be vulnerable to surges. 

Comparing Whole-Home Surge Protection to Power Strips 

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

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

Benefits of Whole-Home Surge Protection 

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

Benefits of whole-home HVAC surge protection include: 

  • Lower repair expenses. Avoiding surge damage can help reduce expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. vulnerable technological components experience less electrical stress over time when protected correctly. 
  • Home electronics protection. In addition to protecting your HVAC, a whole-house surge protector also safeguards appliances, computers and entertainment systems. 
  • Added confidence during severe weather. Homeowners gain added confidence when weather-related power outages occur. 
  • Defense against everyday electrical fluctuations. Minor electrical surges can gradually damage electronic HVAC equipment. 

5 Signs You May Need Surge Protection 

  1. Severe weather. Given the frequent summer storms in Menomonie and western Wisconsin, lightning protection for your HVAC can help lower the risk of surge-related damage. 
  2. Power outages or flickering lights. Repeated outages and voltage fluctuations increase the likelihood of electrical surges. 
  3. Outdated home wiring. Old wiring or outdated electrical equipment can increase your home’s surge risk. 
  4. Expensive HVAC 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. Smart home devices. Homes with smart thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Absolutely. Whole-house surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. Compared with repair costs, installing surge protection is typically much lower than repairing or replacing damaged heating and cooling components, which can help extend the life of your home comfort system.

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

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 homes that experience many severe storms or utility power fluctuations may need replacement sooner.

It can. Homeowners insurance may cover power surge damage, but coverage depends on your policy and the cause of the surge. Because deductibles and coverage vary, surge protection installation is often a smart way to help prevent expensive HVAC repairs.

It can. Power surge protection for HVAC helps shield smart thermostats and other connected HVAC components from damaging voltage spikes. It can also improve system lifespan and reduce the risk of extensive repairs to modern heating and cooling equipment.
