Many homeowners think power surges only happen during lightning storms. Although 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 electrical surges inside your home. 

These surges don’t just pose a risk to televisions and computers. These surges can cause HVAC electrical damage because modern heating and cooling systems rely on advanced electronic components. The good news is HVAC surge protection can help safeguard 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 running through your home’s wiring. While it lasts only a fraction of a second, it can damage household electronics, including HVAC equipment. 

Lightning is the most well-known cause, but many surges happen much closer to home. Utility companies regularly switch power on the electrical grid, and voltage can also spike when electricity is restored after an outage. Household 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 contribute to surges. 

Though a single significant surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and cooling equipment over time, shortening their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

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

HVAC parts that are especially sensitive 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 sensitive 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. 
  • Inverter technology. Systems with variable-capacity operation use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Need the Most Protection? 

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

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

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Airconditioner compressors. This component is one of the costliest parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors that circulate conditioned air throughout your home. 
  • Capacitors. Electrical surges can weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after frequent voltage spikes. 
  • Electronic heat pump components. Modern heat pumps use multiple electronic components which are vulnerable to surges. 

Whole-Home Surge Protection vs. Power Strips 

Many homeowners use surge-protecting power strips for computers and televisions, but these plug-in devices don’t protect your furnace or air conditioner. For complete HVAC system protection, whole-home surge protection offers more comprehensive coverage and greater long-term value. 

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

Benefits of Whole-Home Surge Protection 

Using whole-home surge protection is a proactive way to protect your HVAC investment while also helping safeguard other valuable electronics throughout your home. 

Benefits of whole-home HVAC surge protection include: 

  • Reduced repaircosts. Avoiding surge damage can help reduce expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. vulnerable technological components experience reduced electrical stress over time when protected correctly. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-house surge protector also helps protect appliances, computers and entertainment systems. 
  • Less stress during storms. You’ll have added confidence when severe weather strikes. 
  • Defense against everyday electrical fluctuations. Small voltage spikes can gradually damage connected HVAC devices. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Regular summer storms. Given the strong summer storms in Bloomfield, lightning protection for your HVAC can help lower the risk of power surge damage. 
  2. Frequent power outages or flickering lights. Repeated outages and voltage fluctuations increase the likelihood of electrical surges. 
  3. Aging electrical systems. Old wiring or substandard electrical equipment can increase your home’s surge risk. 
  4. Expensive HVAC equipment. Protecting 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 smart 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? 

Yes. Installing whole-home surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. Installing surge protection is typically much lower than repairing or replacing damaged HVAC components, which can help extend the life of your home comfort system. 

Can a sudden power spike damage an AC unit? 

Yes. A power surge can damage an air conditioner’s compressor, circuit board and blower motor, leading to expensive repairs. A surge protector for your AC helps protect your air conditioner from electrical surges by shielding the sensitive HVAC components. 

What can cause power surges throughout a home? 

Lightning strikes, utility grid switching and power outages are among the most common causes of power surges in homes. They can also result from 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 actual service life 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 need replacement sooner. 

Does homeowners insurance cover power surge damage? 

It can. Homeowners insurance can cover power surge damage, but coverage depends on your policy and the reason for the surge. Because deductibles and coverage vary, surge protection installation is often a smart way to avoid paying for preventable and expensive HVAC repairs. 

Does surge protection help protect smart thermostats? 

Absolutely. Power surge protection for HVAC helps safeguard 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.
