Many homeowners 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 voltage spikes inside your home. 

These surges don’t just damage televisions and computers. They can also cause HVAC electrical damage because modern heating and cooling systems rely on advanced electronic components. Fortunately, HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of costly repairs. 

What Are Power Surges  

A power surge in your home is a sudden spike in electrical voltage in your home’s wiring. Even though it lasts only a fraction of a second, it may damage home electronics. 

Lightning is the most well-known cause, but power surges often occur 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. Major 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 can cause surges. 

Though a single significant surge can cause immediate damage, repeated minor surges can slowly wear down heating and cooling equipment over time, limiting their lifespan. 

Why Modern HVAC Systems Require Better Surge Protection 

Today’s heating and cooling systems use high-tech electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they can make equipment more vulnerable to damage from voltage spikes, highlighting 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 very small voltage spikes. 
  • Variable-speed blower motors. These advanced motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that automatically adjust your HVAC equipment. 
  • Communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for efficient 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 Vulnerable to Power Surges? 

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

HVAC components most vulnerable to power surges in Brookfield include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • Compressors. The compressor is one of the costliest 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. Electrical surges can weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. These devices may malfunction after repeated voltage spikes. 
  • Electronic heat pump components. Heat pumps rely on multiple electronic components which are 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 complete HVAC system protection, whole-home surge protection offers broader coverage and greater long-term value. 

A professionally installed whole-house surge protector is located at your home’s electrical panel. Instead of regulating electricity to only one outlet, it can help safeguard major appliances and electronics throughout your house, including your HVAC system. 

Benefits of Whole-Home Surge Protection 

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

Benefits of whole-house HVAC surge protection include: 

  • Fewer repair costs. Preventing surge damage can help prevent expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Sensitive components experience reduced electrical stress over time when protected correctly. 
  • Protection for household electronics. In addition to protecting your HVAC, a whole-house surge protector also helps protect appliances, computers and entertainment systems. 
  • Less stress during storms. Surge protection provides added confidence when severe storms strike your area. 
  • Defense against everyday electrical fluctuations. Small voltage spikes can gradually damage your HVAC system. 

5 Signs You May Need Surge Protection 

  1. Regular summer storms. Given the powerful summer storms in Brookfield, lightning protection for your HVAC can help lower the risk of power surge damage. 
  2. Power outages or flickering lights. Ongoing power interruptions and changing voltage levels increase the likelihood of damaging voltage spikes. 
  3. Aging electrical systems. Old wiring or substandard electrical equipment can increase your home’s surge risk. 
  4. High-efficiency HVAC equipment. Shielding a high-efficiency heating and cooling system by installing whole-home surge protection is often less expensive than repairing or replacing damaged components. 
  5. Smart home devices. Homes with smart thermostats and other connected devices have more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

In most cases, yes. Installing whole-home surge protection is often a smart investment because it helps protect expensive HVAC equipment. 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.

Absolutely. A power surge can damage your AC unit’s compressor, circuit board and blower motor, which can cause expensive repairs. Installing AC surge protection can protect your air conditioner from electrical surges by reducing the impact of voltage spikes before they reach 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. Another possible cause is problems within your home’s electrical system. Repeated minor power surges can gradually wear down HVAC components over time.

A typical whole-home surge protector lasts about 5 to 10 years, although its lifespan depends on the number and severity of the surges it absorbs. Surge protector systems in homes that experience many severe storms or utility power fluctuations may require replacement sooner.

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

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