Homeowners often think power surges occur only during lightning storms. While lightning is definitely 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 electrical surges don’t just pose a risk to televisions and computers. These surges can cause HVAC electrical damage because today’s heating and cooling systems rely on highly sensitive electronic components. Thankfully, 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 in your home is a short spike in electrical voltage that travels through your home’s wiring. While it lasts only a fraction of a second, it can damage home electronics. 

Lightning is the most well-known cause, but many surges happen much closer to home. Electric utility providers routinely switch power on the electrical grid, and voltage can also spike when electricity is restored after an outage. Major appliances like refrigerators or air conditioners can also create small voltage fluctuations when they cycle on and off. It’s also possible that loose wiring or other home electrical issues contribute to surges. 

Though a single significant surge can cause immediate damage, repeated minor surges can slowly wear down heating and air conditioning systems over time, shortening their lifespan. 

Why Modern HVAC Systems Are More Vulnerable 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 at risk of damage from voltage spikes, increasing the importance of HVAC electrical protection. 

HVAC parts that are especially sensitive 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 blower motors. These advanced 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. 
  • Communication systems. Many newer heating and air conditioning systems use electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Variable-capacity inverter technology. Variable-capacity HVAC systems use sophisticated electronics that work best with surge protection. 

Which HVAC Components Need the Most Protection? 

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

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

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • HVAC compressors. This component is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Electrical surges can damage motors responsible for circulating conditioned air throughout your home. 
  • HVAC system capacitors. Surges can weaken or damage these components, impacting system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats can malfunction after frequent voltage spikes. 
  • Electronic heat pump components. Heat pumps rely on multiple electronic components which are vulnerable to surges. 

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

Many people use surge-protecting power strips for computers and televisions, but power strips don’t protect your HVAC system. For HVAC system protection, whole-home surge protection offers broader coverage and long-term value. 

A professionally installed whole-home 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 

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: 

  • Reduced repaircosts. Preventing surge damage can help avoid expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Electronic HVAC components experience reduced electrical stress over time when properly protected. 
  • Protection for household electronics. In addition to protecting your HVAC, a whole-house surge protector also safeguards appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Surge protection provides added confidence when severe storms strike your area. 
  • Protection from everyday electrical fluctuations. Even small, routine surges can gradually damage your HVAC system. 

5 Signs It’s Time to Consider Surge Protection 

  1. Severe weather. Given the strong summer storms in Laurel, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Frequent power outages or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of power surges. 
  3. Older electrical systems. Old wiring or obsolete electrical equipment can add to your home’s surge risk. 
  4. Expensive HVAC equipment. Safeguarding a high-efficiency heating and cooling system with a surge protector is often less expensive than repairing or replacing damaged components. 
  5. Smart home devices. Homes with smart thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Is a whole-house surge protection beneficial for an HVAC system? 

Yes. Whole-home surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. Installing surge protection is typically much lower than repairing or replacing damaged HVAC components, helping extend the life of your home comfort system. 

Can an electrical surge damage an an air conditioning system? 

Absolutely. A power surge can damage your AC unit’s compressor, circuit board and blower motor, resulting in costly repairs. Installing AC surge protection can protect your air conditioner from power surges by preventing the surges from reaching sensitive HVAC components. 

What can cause power surges throughout a home? 

Lightning strikes, utility grid switching and power outages are among the most common causes of power surges in homes. Another possible cause is problems within your home’s electrical system. Repeated minor power surges can gradually wear down HVAC components over time. 

What is the average lifespan of a whole-house surge protector? 

Most whole-home surge protectors last 5 to 10 years, although actual service life depends on the number and severity of the surges it absorbs. Surge protector systems in a home that has frequent storms or utility power fluctuations may require replacement sooner. 

Does homeowners insurance cover power surge damage? 

It depends. Homeowners insurance may cover power surge damage, but coverage depends on your policy and what caused the surge. With policy limits and deductibles varying, surge protection installation is often a smart way to avoid paying for preventable and expensive HVAC repairs. 

Does surge protection help protect smart thermostats? 

Yes. Power surge protection for HVAC helps shield smart thermostats and other connected HVAC components from damaging voltage spikes. It also helps improve system lifespan and reduce the risk of expensive repairs to modern heating and cooling equipment.
