Homeowners often think power surges are limited to lightning storms. While lightning is definitely one cause, it isn’t 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 pose a risk to televisions and computers. They can also cause HVAC electrical damage because today’s heating and cooling systems rely on advanced electronic components. Fortunately, HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of major repairs. 

What Is a Power Surge  

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

Lightning remains the most well-known cause, but many surges happen much closer to home. Power companies frequently adjust power on the electrical grid, and electrical surges also can happen when electricity is restored after an outage. Major 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 lead to surges. 

While a single large surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and air conditioning systems over time, shortening their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Modern heating and cooling systems use sophisticated electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they also make equipment more at risk of damage from voltage spikes, highlighting 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 minimal voltage spikes. 
  • Variable-speed blower 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. 
  • Electronic communication systems. Many newer heating and air conditioning systems use electronic communication between indoor and outdoor units for efficient operation. 
  • Variable-capacity inverter technology. Variable-capacity HVAC systems use sophisticated electronics that benefit from surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components most vulnerable to power surges in Norton include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • 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 that circulate conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, reducing system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after repeated voltage spikes. 
  • Heat pumpelectronics. Modern heat pumps use multiple electronic components which are 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 these plug-in devices don’t protect your HVAC system. To provide complete HVAC system protection, whole-home surge protection offers greater coverage and lasting value. 

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

Benefits of Whole-Home Surge Protection 

Using 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. Preventing surge damage can help reduce expensive HVAC repairs. 
  • Extended HVAC system lifespan. Electronic HVAC components experience reduced electrical stress over time when properly protected. 
  • Protection of homeelectronics. In addition to protecting your HVAC, whole-home surge protection also shields appliances, computers and entertainment systems. 
  • Added confidence during severe weather. Homeowners gain added confidence when severe weather strikes. 
  • Defense against everyday electrical fluctuations. Small voltage spikes can gradually damage electronic HVAC equipment. 

5 Signs It’s Time to Consider Surge Protection 

  1. Frequent storms. Given the powerful summer storms in Norton, lightning protection for your HVAC can help minimize the risk of power surge damage. 
  2. Blackouts or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of electrical surges. 
  3. Aging electrical systems. Old wiring or substandard electrical equipment can add to your home’s surge risk. 
  4. Modern heating and cooling 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 technology. Homes with connected thermostats and other connected devices have more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Absolutely. Whole-house 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 furnace or air conditioner components, helping extend the life of your home comfort system.

Absolutely. A power surge can damage an air conditioner’s compressor, circuit board and blower motor, resulting in costly repairs. A surge protector for your AC helps protect your air conditioner from electrical fluctuations by preventing the surges from reaching sensitive HVAC components.

Lightning strikes, utility grid switching and power outages are among the most common causes of power surges in homes. They can also result from problems within your home’s electrical system. Even small, repeated surges can gradually wear down HVAC components over time.

A typical whole-home surge protector lasts about 5 to 10 years, although that depends on the number and severity of the surges it absorbs. Surge protector systems in properties that experience frequent storms or utility power fluctuations may require replacement sooner.

In some cases, but not all. Homeowners insurance sometimes cover power surge damage, but coverage depends on your policy and the reason for the surge. With policy limits and deductibles varying, surge protection installation is often cost-effective way to protect your pocketbook from expensive HVAC repairs.

Absolutely. Power surge protection for HVAC helps shield smart thermostats and other connected HVAC components from power surges. Surge protection may also improve system lifespan and reduce the risk of costly repairs to your home’s heating and cooling equipment.
