Homeowners often think power surges only happen 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 electrical surges don’t just damage televisions and computers. They may also cause HVAC electrical damage because modern heating and cooling systems rely on advanced electronic components. The good news is HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Is a Power Surge  

A power surge in your home 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 electrical surges begin much closer to home. Utility companies regularly switch power on the electrical grid, and power can also surge when electricity is restored after an outage. Household appliances like refrigerators or air conditioners 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, repeated minor surges can slowly wear down heating and air conditioning systems over time, shortening their lifespan. 

Why Modern HVAC Systems Require Better Surge Protection 

Many of today’s heating and cooling systems use advanced electronics to improve comfort and energy efficiency. Even though hese advanced features offer many benefits, they can also make equipment more sensitive to voltage spikes, highlighting the importance of HVAC electrical protection. 

HVAC parts that are especially sensitive to power surges include: 

  • Circuit boards. They serve as the system’s control center and can be damaged by even brief or small voltage spikes. 
  • Variable-speed blower motors. These energy-saving motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that control your HVAC equipment. 
  • Electronic communication systems. Modern heating and cooling systems use electronic communication between indoor and outdoor units for efficient operation. 
  • Variable-capacity inverter technology. Variable-capacity HVAC systems rely on sophisticated electronics that work best with surge protection. 

Which HVAC Components Are Most at Risk? 

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

HVAC components most vulnerable to power surges in Bend include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Airconditioner compressors. An HVAC compressor is one of the highest-priced 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. 
  • Capacitors. Surges can weaken or damage these components, affecting system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats 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 people 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 greater coverage and greater long-term value. 

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

Benefits of Whole-Home Surge Protection 

Adding whole-home surge protection is an effective way to protect your HVAC investment while also helping safeguard other valuable electronics throughout your home. 

Benefits of whole-house HVAC surge protection include: 

  • Lower repair expenses. Reducing surge damage can help reduce expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. vulnerable technological components experience less electrical stress over time when protected correctly. 
  • Protection for household electronics. In addition to protecting your HVAC, a whole-house surge protector also safeguards appliances, computers and entertainment systems. 
  • Less stress during storms. You’ll have added confidence when severe storms strike your area. 
  • Protectionagainst everyday electrical fluctuations. Small voltage spikes can gradually damage electronic HVAC equipment. 

5 Signs It’s Time to Consider Surge Protection 

  1. Frequent storms. Given the strong summer storms in Bend, lightning protection for your HVAC can help minimize the risk of electrical surge damage. 
  2. Blackouts or flickering lights. Ongoing power interruptions and electrical fluctuations increase the likelihood of power 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 technology. Homes with Wi-Fi thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

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

Absolutely. Whole-home 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 furnace or air conditioner components, and it helps extend the life of your home comfort system. 

Can an electrical surge damage an air conditioner? 

It can. A power surge can damage your AC unit’s compressor, circuit board and blower motor, leading to costly repairs. AC surge protection helps protect your air conditioner from electrical fluctuations by reducing the impact of voltage spikes before they reach sensitive HVAC components. 

What causes power surges inside a home? 

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

How long does whole-home surge protection last? 

A whole-house surge protector usually lasts 5 to 10 years, although its lifespan 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. 

Does homeowners insurance cover power surge damage? 

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. 

Does a surge protector help protect smart thermostats? 

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