Homeowners often think power surges occur only during lightning storms. Although lightning is one cause, it isn’t the only one. Utility switching, power outages/restoration and even large appliances cycling on and off can all create power surges inside your home. 

These electric voltage spikes don’t just pose a risk to televisions and computers. These surges can cause HVAC electrical damage because today’s heating and cooling systems rely on advanced electronic components. Thankfully, HVAC surge protection can help safeguard one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Are Power Surges  

A home power surge is a sudden spike in electrical voltage in 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. Electric utility providers routinely switch 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 small voltage fluctuations when they cycle on and off. It’s also possible that 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 heating and air conditioning systems over time, limiting their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Modern heating and cooling systems use advanced electronics to improve comfort and energy efficiency. Although these technologies 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: 

  • Control boards. They function as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Energy-efficient 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. Many newer heating and air conditioning systems use electronic communication between indoor and outdoor units for reliable operation. 
  • Inverter-driven technology. Systems with variable-capacity operation use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most at Risk? 

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

HVAC components most vulnerable to power surges in Port Orchard include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Airconditioner compressors. The compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Electrical surges can damage motors that circulate conditioned air throughout your home. 
  • HVACcapacitors. Power surges may weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. Electronic thermostats can malfunction after repeated voltage spikes. 
  • Heat pump control electronics. Heat pumps rely on multiple electronic components that are particularly vulnerable to surges. 

Whole-Home Surge Protection vs. 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 HVAC system protection, whole-home surge protection offers more comprehensive coverage and lasting value. 

A professionally installed whole-home surge protector is connected at your home’s electrical panel. Rather than protecting only one outlet, it helps safeguard major appliances and electronics throughout your house, including your HVAC system. 

Benefits of Whole-Home HVAC Surge Protection 

Installing whole-home surge protection is a smart way to protect your HVAC investment while also working to safeguard other valuable electronics throughout your home. 

Benefits of whole-home HVAC surge protection include: 

  • Reduced repaircosts. Reducing surge damage can help avoid expensive HVAC repairs. 
  • Longer HVAC equipmentlife. vulnerable technological components experience lower electrical stress over time when protected correctly. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-home surge protector also safeguards appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Surge protection provides added confidence when severe weather strikes. 
  • Protectionagainst 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 frequent summer storms in Port Orchard, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Power outages or flickering lights. Ongoing power interruptions and voltage fluctuations increase the likelihood of damaging voltage spikes. 
  3. Outdated home wiring. Old wiring or substandard electrical equipment can raise your home’s surge risk. 
  4. High-efficiency HVAC equipment. Protecting 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. Connected home technology. Homes with connected 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. Compared with repair costs, installing surge protection is typically much lower than repairing or replacing damaged furnace or air conditioner components, and it helps extend the life of your home comfort system.

Yes. A power surge can damage your AC unit’s compressor, circuit board and blower motor, leading to major repairs. AC surge protection 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. They can also result from problems within your home’s electrical system. Repeated minor power surges can gradually wear down HVAC components over time.

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 properties that experience 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 what caused the surge. With policy limits and deductibles varying, surge protection installation is often cost-effective way to help prevent expensive HVAC repairs.

Absolutely. Power surge protection for HVAC helps protect smart thermostats and other connected HVAC components from electrical surges. Surge protection may also improve system performance and reduce the risk of extensive repairs to modern heating and cooling equipment.
