Many people think power surges only happen during lightning storms. While lightning is 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 electrical surges don’t just threaten televisions and computers. They can also cause HVAC electrical damage because current heating and cooling systems rely on highly sensitive electronic components. Fortunately, 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 sudden spike in electrical voltage that travels through your home’s wiring. Although it lasts only a fraction of a second, it still can damage household electronics, including HVAC equipment. 

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. Major appliances like refrigerators or HVAC systems can also create small voltage fluctuations when they cycle on and off. In some cases, loose wiring or other home electrical issues lead to surges. 

While a single large surge can cause immediate damage, repeated minor surges can slowly wear down HVAC components over time, reducing 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 also make equipment more sensitive to voltage spikes, highlighting the importance of HVAC electrical protection. 

Some of the most at-risk HVAC components to power surges include: 

  • Circuit boards. These act as the system’s control center and can be damaged by even very small voltage spikes. 
  • Variable-speed motors. These advanced motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that communicate with your HVAC equipment. 
  • Electronic communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for reliable operation. 
  • Variable-capacity inverter technology. Systems with variable-capacity operation use sophisticated electronics that benefit from surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

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

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Airconditioner compressors. An HVAC compressor is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors used to move conditioned air throughout your home. 
  • HVAC system capacitors. Power surges may weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after multiple voltage spikes. 
  • Heat pump control electronics. Modern heat pumps use multiple electronic components that are particularly vulnerable to surges. 

Comparing Whole-Home Surge Protection to Power Strips 

Many homeowners use surge-protecting power strips for computers and televisions, but these plug-in devices don’t protect your heating and cooling system. For HVAC system protection, whole-home surge protection offers broader coverage and greater long-term value. 

A professionally installed whole-home surge protector is set up right at your home’s electrical panel. Rather than protecting only one outlet, the system helps safeguard major appliances and electronics throughout the house, including your heating and cooling equipment. 

Benefits of Whole-Home HVAC Surge Protection 

Adding whole-home surge protection is a proactive 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. Preventing surge damage can help reduce expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. Electronic HVAC components experience reduced electrical stress over time when protected correctly. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-home surge protector also helps protect appliances, computers and entertainment systems. 
  • Less stress during storms. Surge protection provides added confidence when weather-related power outages occur. 
  • Protection from everyday electrical fluctuations. Minor electrical surges can gradually damage connected HVAC devices. 

5 Signs It’s Time to Consider Surge Protection 

  1. Frequent storms. Given the strong summer storms in Eastland, lightning protection for your HVAC can help minimize the risk of surge-related damage. 
  2. Frequent power outages or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of electrical surges. 
  3. Older electrical systems. Old wiring or substandard electrical equipment can raise your home’s surge risk. 
  4. Modern heating and cooling equipment. Protecting a high-efficiency heating and cooling system with a surge protector is often far less costly than repairing or replacing damaged components. 
  5. Connected home technology. Homes with connected thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Is whole-home surge protection worth it for an HVAC system? 

In most cases, yes. Whole-house surge protection is often a smart 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 a power surge damage an AC unit? 

Yes. A power surge can damage an air conditioner’s compressor, circuit board and blower motor, resulting in costly repairs. AC surge protection helps protect your air conditioner from electrical fluctuations by shielding the sensitive HVAC components. 

What can cause 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. Even small, repeated surges can gradually wear down HVAC components over time. 

How long does a whole-home surge protector last? 

A whole-house surge protector usually lasts 5 to 10 years, although that depends on the number and severity of the surges it absorbs. Surge protector systems in a home that has frequent storms or utility power fluctuations may need replacement sooner. 

Does a homeowners insurance policy cover damage caused by power surges? 

It depends. Homeowners insurance sometimes cover power surge damage, but coverage depends on your policy and the reason for the surge. With policy limits and deductibles varying, surge protection installation is often a smart way to help prevent expensive HVAC repairs. 

Will whole-home surge protection help protect smart thermostats? 

Absolutely. Power surge protection for HVAC helps protect smart thermostats and other connected HVAC components from power surges. It also helps improve system longevity and reduce the risk of expensive repairs to your home’s heating and cooling equipment.
