Homeowners often think power surges only happen during lightning storms. While lightning is one cause, it’s far from the only one. Utility grid activity, restoring power after outages and large household appliances cycling can all create electrical surges inside your home. 

These electric voltage spikes don’t just damage televisions and computers. They can also cause HVAC electrical damage because today’s heating and cooling systems rely on sophisticated electronic components. Thankfully, 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 power surge is a brief spike in electrical voltage that travels through your home’s wiring. Although it lasts only a fraction of a second, it can damage home electronics. 

Lightning remains the most well-known cause, but many electrical surges begin 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. Large appliances like refrigerators or HVAC systems 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 surges can slowly wear down HVAC components over time, shortening their lifespan. 

Why Modern HVAC Systems Need More Surge Protection 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, increasing the importance of HVAC electrical protection. 

HVAC parts that are especially sensitive to power surges include: 

  • Electronic circuit boards. These act as the system’s control center and can be damaged by even brief or small voltage spikes. 
  • Energy-efficient variable-speed motors. These advanced motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that communicate with your HVAC equipment. 
  • HVAC system communication controls. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for reliable operation. 
  • Variable-capacity inverter technology. Variable-capacity HVAC systems rely on sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most at Risk? 

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

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

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Airconditioner compressors. An HVAC compressor is one of the highest-priced 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. 
  • HVACcapacitors. Electrical surges can weaken or damage these components, affecting system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after repeated voltage spikes. 
  • Electronic heat pump components. Modern heat pumps use multiple electronic components that are particularly vulnerable to surges. 

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

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

A professionally installed whole-house surge protector is set up right 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 HVAC equipment. 

Benefits of Whole-Home HVAC Surge Protection 

Adding 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-house HVAC surge protection include: 

  • Lower repair expenses. Preventing surge damage can help avoid expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Electronic HVAC components experience less electrical stress over time when properly protected. 
  • Home electronics protection. In addition to protecting your HVAC, whole-home surge protection also safeguards appliances, computers and entertainment systems. 
  • Added confidence during severe weather. Surge protection provides added confidence when weather-related power outages occur. 
  • Protection from everyday electrical fluctuations. Minor electrical surges can gradually damage electronic HVAC equipment. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the powerful summer storms in Hudsonville, 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. Outdated home wiring. Old wiring or outdated electrical equipment can raise your home’s surge risk. 
  4. Modern heating and cooling equipment. Shielding a high-efficiency heating and cooling system by installing whole-home surge protection is often far less costly 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 

Is HVAC surge protection a good investment? 

In most cases, yes. Whole-house surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. The cost of installing surge protection is typically much lower than repairing or replacing damaged heating and cooling components, and it helps extend the life of your home comfort system. 

Can a power surge damage an AC unit? 

Absolutely. A power surge can damage your AC unit’s compressor, circuit board and blower motor, leading to expensive repairs. Installing AC surge protection can protect your air conditioner from power surges by preventing the surges from reaching sensitive HVAC components. 

What causes power surges throughout 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. Repeated minor power surges can gradually wear down HVAC components over time. 

What is the average lifespan of a whole-house surge protector? 

A whole-house surge protector usually lasts 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. 

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

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. 

Can whole-home surge protection help protect smart thermostats? 

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