Many people think power surges only happen during lightning storms. Although lightning is one cause, it’s certainly not 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 threaten televisions and computers. They may also cause HVAC electrical damage because today’s heating and cooling systems rely on advanced electronic components. Fortunately, 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 home power surge is a short spike in electrical voltage running through your home’s wiring. Although it lasts only a fraction of a second, it still can damage household electronics, including HVAC equipment. 

Lightning is 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. Sometimes, loose wiring or other home electrical issues contribute to surges. 

Although one major power surge can cause immediate damage, repeated minor surges can slowly wear down HVAC components over time, limiting their lifespan. 

Why Modern HVAC Systems Require Better Surge Protection 

Many of today’s heating and cooling systems use high-tech electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they also make equipment more sensitive to voltage spikes, highlighting the importance of HVAC electrical protection. 

Some of the most vulnerable components to power surges include: 

  • Electronic circuit boards. These act as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Variable-speed motors. These energy-saving motors rely on electronic controls that are susceptible to electric surges. 
  • Smart thermostats. Smart home devices are made with delicate electronics that automatically adjust your HVAC equipment. 
  • HVAC system communication controls. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter-driven technology. Variable-capacity HVAC systems use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Need the Most Protection? 

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

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

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • Airconditioner compressors. The compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors that circulate conditioned air throughout your home. 
  • HVACcapacitors. Power surges may weaken or damage these components, reducing system startup and performance. 
  • Smartthermostats. These devices may malfunction after frequent voltage spikes. 
  • Heat pumpelectronics. Heat pump systems depend on multiple electronic components that can be vulnerable to surges. 

Comparing Whole-Home Surge Protection to Power Strips 

Many homeowners use surge-protecting power strips for computers and televisions, but those devices don’t protect your heating and cooling system. To provide complete HVAC system protection, whole-home surge protection offers broader coverage and long-term value. 

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

Benefits of Whole-Home Surge Protection 

Using whole-home surge protection is a proactive 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-lasting HVAC equipment. Sensitive components experience lower electrical stress over time when properly protected. 
  • Home electronics protection. In addition to protecting your HVAC, whole-home surge protection also shields appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Homeowners gain added confidence when severe weather strikes. 
  • Protection from everyday electrical fluctuations. Even small, routine surges can gradually damage electronic HVAC equipment. 

5 Signs You May Need Surge Protection 

  1. Frequent storms. Given the strong summer storms in Eastland, lightning protection for your HVAC can help minimize the risk of surge-related damage. 
  2. Power outages or flickering lights. Ongoing power interruptions and electrical fluctuations increase the likelihood of damaging voltage spikes. 
  3. Aging electrical systems. Old wiring or obsolete electrical equipment can raise 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 less expensive than repairing or replacing damaged components. 
  5. Connected home technology. Homes with smart thermostats and other connected devices have more sensitive electronics to protect.
