Many people think power surges only happen during lightning storms. Although lightning is one cause, it’s far from the only one. Utility grid activity, restoring power after outages and large household appliances cycling can all create power surges inside your home. 

These electric voltage spikes don’t just threaten televisions and computers. They may also cause HVAC electrical damage because current heating and cooling systems rely on highly sensitive electronic components. The good news is HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Is a Power Surge  

A power surge is a sudden spike in electrical voltage running through your home’s wiring. Although it lasts only a fraction of a second, it still can damage electronic components. 

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 electrical surges also can happen when electricity is restored after an outage. Household appliances like refrigerators or AC units 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. 

Although one major power surge can cause immediate damage, repeated minor surges can slowly wear down heating and air conditioning systems over time, limiting their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Modern 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: 

  • Electronic circuit boards. They serve as the system’s control center and can be damaged by even very small voltage spikes. 
  • Energy-efficient variable-speed motors. These advanced motors rely on electronic controls that are susceptible to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that automatically adjust your HVAC equipment. 
  • Communication systems. Today’s HVAC systems rely on electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Variable-capacity inverter technology. Systems with variable-capacity operation use sophisticated electronics that benefit from surge protection. 

Which HVAC Components Need the Most Protection? 

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

HVAC components most commonly affected by power surges in Wyandotte include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Airconditioner compressors. The compressor is one of the costliest parts of an air conditioner or heat pump to replace. 
  • Blower motors.Power surges can damage motors that circulate conditioned air throughout your home. 
  • HVAC system capacitors. Power surges may weaken or damage these components, reducing system startup and performance. 
  • Smartthermostats. These devices may malfunction after repeated voltage spikes. 
  • Heat pump control electronics. Heat pump systems depend on multiple electronic components that can be vulnerable to surges. 

Which is Better for My Home: Whole-Home Surge Protection or Power Strips? 

Homeowners commonly use surge-protecting power strips for computers and televisions, but those devices don’t protect your furnace or air conditioner. To provide complete HVAC system protection, whole-home surge protection offers greater coverage and greater long-term value. 

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

Benefits of Whole-Home Surge Protection 

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

Benefits of whole-home HVAC surge protection include: 

  • Fewer repair costs. Reducing surge damage can help reduce expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. Electronic HVAC components experience lower electrical stress over time when properly protected. 
  • Home electronics protection. In addition to protecting your HVAC, whole-home surge protection also helps protect appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Homeowners gain added confidence when severe weather strikes. 
  • Protectionagainst everyday electrical fluctuations. Minor electrical surges can gradually damage your HVAC system. 

5 Signs It’s Time to Consider Surge Protection 

  1. Regular summer storms. Given the powerful summer storms in Wyandotte, lightning protection for your HVAC can help reduce the risk of surge-related damage. 
  2. Blackouts or flickering lights. Ongoing power interruptions and voltage fluctuations increase the likelihood of damaging voltage spikes. 
  3. Outdated home wiring. Old wiring or substandard electrical equipment can increase your home’s surge risk. 
  4. Modern heating and cooling equipment. Shielding a high-efficiency heating and cooling system by installing whole-home surge protection is often more affordable than repairing or replacing damaged components. 
  5. Connected home technology. Homes with smart thermostats and other connected devices have additional sensitive electronics to protect.
