Many people think power surges are limited to lightning storms. While lightning is one cause, it’s certainly not the only one. Utility grid activity, restoring power after outages and large household appliances cycling can all create voltage spikes 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 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 expensive repairs. 

What Is a Power Surge  

A power surge is a short spike in electrical voltage in your home’s wiring. While it lasts only a fraction of a second, it can damage household electronics, including HVAC equipment. 

Many people know lightning is the most well-known cause, but many electrical surges begin much closer to home. Power companies frequently adjust 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 brief voltage fluctuations when they cycle on and off. It’s also possible that loose wiring or other home electrical issues lead to surges. 

Though a single significant surge can cause immediate damage, repeated minor surges can slowly wear down heating and cooling equipment over time, shortening 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. Even though hese advanced features offer many benefits, they can also make equipment more at risk of damage from voltage spikes, increasing the importance of HVAC electrical protection. 

Some of the most vulnerable components to power surges include: 

  • Electronic circuit boards. They function as the system’s control center and can be damaged by even very small voltage spikes. 
  • Variable-speed blower motors. These energy-saving motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that communicate with your HVAC equipment. 
  • Communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for reliable operation. 
  • Inverter-driven technology. Variable-capacity HVAC systems use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most at Risk? 

Damage from electrical surges 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 electrical surge incidents. 

HVAC components most commonly affected by power surges in Myrtle Beach include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • HVAC compressors. The compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors used to move conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, reducing system startup and performance. 
  • Thermostats and Smart Home Technology. A smart thermostat can malfunction after frequent voltage spikes. 
  • Electronic heat pump components. Heat pumps rely on multiple electronic components that are particularly vulnerable to surges. 

Whole-Home Surge Protection vs. Power Strips 

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

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

Benefits of Whole-Home HVAC Surge Protection 

Adding whole-home surge protection is an effective 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. Reducing surge damage can help reduce expensive HVAC repairs. 
  • Longer HVAC equipmentlife. vulnerable technological components experience lower electrical stress over time when equipped with surge protection. 
  • Protection for household electronics. 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 severe storms strike your area. 
  • Defense against everyday electrical fluctuations. Even small, routine surges can gradually damage your HVAC system. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the frequent summer storms in Myrtle Beach, lightning protection for your HVAC can help minimize the risk of power surge damage. 
  2. Frequent power outages or flickering lights. Repeated outages and electrical fluctuations 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. Safeguarding a high-efficiency heating and cooling system with a surge protector is often far less costly than repairing or replacing damaged components. 
  5. Smart home technology. Homes with smart thermostats and other connected devices have more sensitive electronics to protect.
