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

These electrical surges don’t just threaten televisions and computers. These surges can cause HVAC electrical damage because current heating and cooling systems rely on highly sensitive electronic components. The good news is HVAC surge protection can help protect one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Is a Power Surge  

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

Many people know lightning is the most well-known cause, but power surges often occur 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. Household appliances like refrigerators or air conditioners can also create minor voltage fluctuations when they cycle on and off. In some cases, loose wiring or other home electrical issues can cause surges. 

Though a single significant surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and cooling equipment over time, shortening their lifespan. 

Why Modern HVAC Systems Need More Surge Protection 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 also make equipment more vulnerable to damage from voltage spikes, increasing the importance of HVAC electrical protection. 

Some of the most vulnerable components to power surges include: 

  • Electronic circuit boards. These act as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Variable-speed motors. These advanced motors rely on electronic controls that are susceptible to electric surges. 
  • Smart thermostats. Smart home devices are made with delicate electronics that control your HVAC equipment. 
  • Electronic communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter technology. Systems with variable-capacity operation use sophisticated electronics that work best with surge protection. 

Which HVAC Components Need the Most Protection? 

Damage from electrical surges can cost hundreds or even thousands to repair. Installing electrical surge protection helps reduce the risk of unexpected failures and expensive HVAC repair after power surge incidents. 

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

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • HVAC compressors. The compressor is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors responsible for circulating conditioned air throughout your home. 
  • HVAC system capacitors. Surges can weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after multiple voltage spikes. 
  • Electronic heat pump components. Heat pump systems depend on multiple electronic components which are 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 furnace or air conditioner. For HVAC system protection, whole-home surge protection offers greater coverage and long-term value. 

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

Benefits of Whole-House Surge Protection 

Using 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: 

  • Fewer repair costs. Reducing surge damage can help avoid expensive HVAC repairs. 
  • Extended HVAC system lifespan. vulnerable technological components experience reduced electrical stress over time when properly protected. 
  • Protection of homeelectronics. In addition to protecting your HVAC, whole-home surge protection also helps protect appliances, computers and entertainment systems. 
  • Less stress during storms. Homeowners gain added confidence when weather-related power outages occur. 
  • Protection from everyday electrical fluctuations. Even small, routine surges can gradually damage connected HVAC devices. 

5 Signs You May Need Surge Protection 

  1. Regular summer storms. Given the strong summer storms in Morgantown, lightning protection for your HVAC can help minimize the risk of power surge damage. 
  2. Blackouts or flickering lights. Frequent outages and changing voltage levels increase the likelihood of damaging voltage spikes. 
  3. Outdated home wiring. Old wiring or obsolete electrical equipment can raise your home’s surge risk. 
  4. Modern heating and cooling equipment. Safeguarding a high-efficiency heating and cooling system with a surge protector is often less expensive 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 

Absolutely. Whole-home surge protection is often worth the investment because it helps protect expensive HVAC equipment. The cost of 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 your AC unit’s compressor, circuit board and blower motor, resulting in costly repairs. A surge protector for your AC helps protect your air conditioner from electrical fluctuations by shielding the 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. Power surges may also stem from problems within your home’s electrical system. Small voltage spikes can gradually wear down HVAC components over time.

Most whole-home surge protectors last 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 need replacement sooner.

It depends. Homeowners insurance can cover power surge damage, but coverage depends on your policy and what caused 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 protect smart thermostats and other connected HVAC components from power surges. Surge protection may also improve system lifespan and reduce the risk of extensive repairs to home heating and cooling equipment.
