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

These surges don’t just damage televisions and computers. They can also cause HVAC electrical damage because today’s 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 major repairs. 

What Is a Power Surge  

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

Lightning remains the most well-known cause, but many surges happen much closer to home. Electric utility providers routinely switch power on the electrical grid, and power can also surge when electricity is restored after an outage. Household appliances like refrigerators or HVAC systems can also create brief voltage fluctuations when they cycle on and off. Sometimes, loose wiring or other home electrical issues contribute to surges. 

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

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Many of today’s heating and cooling systems use high-tech electronics to improve comfort and energy efficiency. While these features offer many benefits, they also make equipment more at risk of damage from voltage spikes, increasing the importance of HVAC electrical protection. 

Some of the most vulnerable components to power surges include: 

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

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components most commonly affected by power surges in Laurel include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • Compressors. An HVAC compressor 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. Surges can weaken or damage these components, reducing system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after repeated voltage spikes. 
  • Heat pump control electronics. Heat pumps rely on multiple electronic components that can be vulnerable to surges. 

Which is Better for My Home: Whole-Home Surge Protection or Power Strips? 

Many people use surge-protecting power strips for computers and televisions, but power strips don’t protect your heating and cooling system. For complete HVAC system protection, whole-home surge protection offers more comprehensive coverage and lasting value. 

A professionally installed whole-house surge protector is connected at your home’s electrical panel. Instead of regulating electricity to only one outlet, the system helps safeguard major appliances and electronics throughout your entire house, including your heating and cooling equipment. 

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: 

  • Reduced repaircosts. Preventing surge damage can help prevent expensive HVAC repairs. 
  • Extended HVAC system lifespan. Sensitive components experience lower electrical stress over time when equipped with surge protection. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-home surge protector also helps protect appliances, computers and entertainment systems. 
  • Added confidence during severe weather. You’ll have added confidence when weather-related power outages occur. 
  • Protectionagainst everyday electrical fluctuations. Small voltage spikes can gradually damage connected HVAC devices. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the powerful summer storms in Laurel, lightning protection for your HVAC can help minimize the risk of electrical surge damage. 
  2. Power outages or flickering lights. Repeated outages and voltage fluctuations increase the likelihood of power surges. 
  3. Older electrical systems. Old wiring or outdated electrical equipment can raise your home’s surge risk. 
  4. Expensive HVAC equipment. Safeguarding a high-efficiency heating and cooling system by installing whole-home surge protection is often more affordable than repairing or replacing damaged components. 
  5. Smart home technology. Homes with Wi-Fi thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

In most cases, yes. Whole-home surge protection is often worth the investment because it helps protect expensive HVAC equipment. Installing surge protection is typically much lower than repairing or replacing damaged HVAC components, helping extend the life of your home comfort system.

It can. A power surge can damage your AC unit’s compressor, circuit board and blower motor, resulting in major repairs. AC surge protection helps protect your air conditioner from power surges by shielding the 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. They can also result 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 actual service life 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 require replacement sooner.

In some cases, but not all. 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 avoid paying for preventable and expensive HVAC repairs.

Yes. Power surge protection for HVAC helps shield smart thermostats and other connected HVAC components from damaging voltage spikes. It also helps improve system reliability and reduce the risk of expensive repairs to home heating and cooling equipment.
