Homeowners often think power surges are limited to lightning storms. While lightning is definitely one cause, it’s far from 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 electrical surges don’t just damage televisions and computers. These surges can cause HVAC electrical damage because modern heating and cooling systems rely on highly sensitive electronic components. The good news is HVAC surge protection can help protect one of your home’s biggest investments and reduce the risk of major repairs. 

What Is a Power Surge  

A power surge in your home is a sudden 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 power surges often occur much closer to home. Utility companies regularly switch power on the electrical grid, and electrical surges also can happen 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 lead to surges. 

Although one major power 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 Need More Surge Protection Than Ever 

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

Some of the most vulnerable components 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 motors. These energy-saving motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that control your HVAC equipment. 
  • Electronic communication systems. Modern heating and cooling systems use electronic communication between indoor and outdoor units for reliable operation. 
  • Inverter technology. Variable-capacity HVAC systems use sophisticated electronics that work best with surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

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

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • Compressors. An HVAC compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors responsible for circulating conditioned air throughout your home. 
  • Capacitors. Electrical surges can weaken or damage these components, reducing system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats can malfunction after frequent voltage spikes. 
  • Heat pump control electronics. Heat pump systems depend on multiple electronic components that can be vulnerable to surges. 

Comparing Whole-Home Surge Protection to Power Strips 

Many people use surge-protecting power strips for computers and televisions, but these plug-in devices don’t protect your furnace or air conditioner. For HVAC system protection, whole-home surge protection offers broader coverage and lasting 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 entire house, including your HVAC system. 

Benefits of Whole-House Surge Protection 

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

Benefits of whole-home HVAC surge protection include: 

  • Fewer repair costs. Reducing surge damage can help prevent expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Sensitive components experience less electrical stress over time when equipped with surge protection. 
  • Home electronics protection. In addition to protecting your HVAC, whole-home surge protection also shields appliances, computers and entertainment systems. 
  • Less stress during storms. Surge protection provides added confidence when weather-related power outages occur. 
  • Protection from everyday electrical fluctuations. Even small, routine surges can gradually damage connected HVAC devices. 

5 Signs It’s Time to Consider Surge Protection 

  1. Regular summer storms. Given the powerful summer storms in Toledo, lightning protection for your HVAC can help reduce the risk of electrical surge damage. 
  2. Power outages or flickering lights. Repeated outages and voltage fluctuations increase the likelihood of power surges. 
  3. Older electrical systems. Old wiring or substandard electrical equipment can raise your home’s surge risk. 
  4. Modern heating and cooling equipment. Safeguarding a high-efficiency heating and cooling system with a surge protector is often more affordable than repairing or replacing damaged components. 
  5. Smart home technology. Homes with connected thermostats and other connected devices have even more sensitive electronics to protect.
