Many people think power surges are limited to lightning storms. While lightning is definitely one cause, it isn’t the only one.  Major appliances turning on and off, electrical grid switching, power outages and restoration can all create voltage spikes inside your home. 

These surges don’t just damage televisions and computers. These surges can cause HVAC electrical damage because current heating and cooling systems rely on sophisticated electronic components. Thankfully, HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Are Power Surges  

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

Many people know 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. Large appliances like refrigerators or HVAC systems can also create minor voltage fluctuations when they cycle on and off. Sometimes, 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, shortening their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Today’s heating and cooling systems use advanced 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, highlighting 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 motors. These advanced motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that automatically adjust your HVAC equipment. 
  • Communication systems. 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 work best with surge protection. 

Which HVAC Components Need the Most Protection? 

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

HVAC components that are frequently damaged by power surges in Crystal and Twin Cities include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Compressors. The compressor is one of the costliest 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. Power surges may weaken or damage these components, reducing system startup and performance. 
  • Thermostats and Smart Home Technology. A smart thermostat can malfunction after frequent voltage spikes. 
  • Heat pump control electronics. Heat pumps rely on multiple electronic components which are 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 power strips don’t protect your HVAC system. For complete HVAC system protection, whole-home surge protection offers more comprehensive 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 system. 

Benefits of Whole-House 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: 

  • Reduced repaircosts. Avoiding surge damage can help avoid expensive HVAC repairs. 
  • Extended HVAC system lifespan. Electronic HVAC 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 shields appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Homeowners gain added confidence when severe storms strike your area. 
  • Protectionagainst everyday electrical fluctuations. Minor electrical surges can gradually damage your HVAC system. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Severe weather. Given the frequent summer storms in Crystal and Twin Cities, lightning protection for your HVAC can help reduce the risk of power surge damage. 
  2. Frequent power outages or flickering lights. Repeated outages and changing voltage levels increase the likelihood of damaging voltage spikes. 
  3. Aging electrical systems. Old wiring or substandard electrical equipment can increase your home’s surge risk. 
  4. Expensive 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. Smart home devices. Homes with Wi-Fi thermostats and other connected devices have additional sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Yes. 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 HVAC components, which can help extend the life of your home comfort system.

Absolutely. A power surge can damage your AC unit’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 surges by reducing the impact of voltage spikes before they reach sensitive HVAC components.

Lightning strikes, utility grid switching and power outages are among the most common causes of power surges in homes. Another possible cause is 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 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 can cover power surge damage, but coverage depends on your policy and the reason for the surge. Because deductibles and coverage vary, surge protection installation is often a smart way to protect your pocketbook from expensive HVAC repairs.
