Many people think power surges only happen during lightning storms. While lightning is 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 voltage spikes inside your home. 

These electrical 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 safeguard one of your home’s biggest investments and reduce the risk of costly repairs. 

What Is a Power Surge  

A power surge is a short spike in electrical voltage that travels through your home’s wiring. Even though it lasts only a fraction of a second, it may damage electronic components. 

Many people know 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 brief 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, smaller surges can slowly wear down heating and air conditioning systems over time, reducing their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

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 make equipment more vulnerable to damage from voltage spikes, highlighting the importance of HVAC electrical protection. 

Some of the most vulnerable components to power surges include: 

  • Control boards. They serve as the system’s control center and can be damaged by even very small voltage spikes. 
  • Variable-speed motors. Variable speed motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Smart home devices are made with delicate electronics that control your HVAC equipment. 
  • Communication systems. Many newer heating and air conditioning systems use electronic communication between indoor and outdoor units for reliable operation. 
  • Inverter technology. Variable-capacity HVAC systems use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most at Risk? 

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

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

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • 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, affecting system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats can malfunction after multiple voltage spikes. 
  • Electronic heat pump components. Modern heat pumps use multiple electronic components that can be 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 power strips don’t protect your furnace or air conditioner. For complete HVAC system protection, whole-home surge protection offers more comprehensive 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, the system helps safeguard major appliances and electronics throughout your entire house, including your heating and cooling equipment. 

Benefits of Whole-Home HVAC Surge Protection 

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

Benefits of whole-house HVAC surge protection include: 

  • Lower repair expenses. Reducing surge damage can help avoid expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. vulnerable technological components experience less electrical stress over time when equipped with surge protection. 
  • Protection for household electronics. In addition to protecting your HVAC, a whole-house surge protector also safeguards appliances, computers and entertainment systems. 
  • Added confidence during severe weather. You’ll have added confidence when severe storms strike your area. 
  • Defense against everyday electrical fluctuations. Minor electrical surges can gradually damage electronic HVAC equipment. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Severe weather. Given the frequent summer storms in Greensburg, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Blackouts or flickering lights. Ongoing power interruptions and voltage fluctuations increase the likelihood of damaging voltage spikes. 
  3. Older electrical systems. Old wiring or obsolete electrical equipment can add to your home’s surge risk. 
  4. Expensive HVAC equipment. Shielding a high-efficiency heating and cooling system with a surge protector is often more affordable than repairing or replacing damaged components. 
  5. Smart home devices. Homes with Wi-Fi thermostats and other connected devices have more sensitive electronics to protect.
