Homeowners often think power surges are limited to 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 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 sophisticated electronic components. The good news is HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of major repairs. 

What Are Power Surges  

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

Lightning is the most well-known cause, but many electrical surges begin 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. Sometimes, loose wiring or other home electrical issues lead to surges. 

While a single large surge can cause immediate damage, smaller surges can slowly wear down heating and cooling equipment over time, shortening their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Today’s heating and cooling systems use high-tech electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they can also make equipment more vulnerable to damage from voltage spikes, increasing 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 minimal voltage spikes. 
  • Variable-speed blower motors. Variable speed motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Connected thermostats contain delicate electronics that control your HVAC equipment. 
  • Communication systems. Modern heating and cooling systems use electronic communication between indoor and outdoor units for reliable operation. 
  • Variable-capacity inverter technology. Systems with variable-capacity operation 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 of dollars to repair or replace. Installing whole-house surge protection helps reduce the risk of unexpected failures and costly HVAC repair after power surge incidents. 

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

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Compressors. An HVAC compressor is one of the costliest 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 repeated voltage spikes. 
  • Heat pump control electronics. Heat pump systems depend on multiple electronic components which are vulnerable to surges. 

Whole-Home Surge Protection vs. 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 more comprehensive coverage and lasting value. 

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

Benefits of Whole-Home Surge Protection 

Adding 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-home HVAC surge protection include: 

  • Fewer repair costs. Reducing surge damage can help prevent expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. Sensitive components experience lower electrical stress over time when equipped with surge protection. 
  • Protection for household electronics. In addition to protecting your HVAC, a whole-home surge protector also safeguards appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Surge protection provides added confidence when weather-related power outages occur. 
  • Protection from everyday electrical fluctuations. Small voltage spikes can gradually damage electronic HVAC equipment. 

5 Signs It’s Time to Consider Surge Protection 

  1. Severe weather. Given the frequent summer storms in Newport, lightning protection for your HVAC can help minimize the risk of power surge damage. 
  2. Frequent power outages or flickering lights. Ongoing power interruptions and electrical fluctuations increase the likelihood of damaging voltage spikes. 
  3. Outdated home wiring. 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 by installing whole-home surge protection is often far less costly than repairing or replacing damaged components. 
  5. Smart home devices. Homes with connected thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

Yes. Whole-house surge protection is often a smart investment because it helps protect expensive HVAC equipment. Compared with repair costs, installing surge protection is typically much lower than repairing or replacing damaged furnace or air conditioner components, and it helps extend the life of your home comfort system.

Yes. A power surge can damage an air conditioning compressor, circuit board and blower motor, resulting in expensive repairs. AC surge protection helps protect your air conditioner from electrical surges by shielding the sensitive HVAC components.

The most common sources of power surges include lightning strikes, utility grid switching, power outages, power restoration and large appliances cycling on and off. Another possible cause is problems within your home’s electrical system. Repeated minor power surges can gradually wear down HVAC components over time.

A typical whole-home surge protector lasts about 5 to 10 years, although its lifespan 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.

It can. Homeowners insurance may cover power surge damage, but coverage depends on your policy and what caused the surge. Because deductibles and coverage vary, surge protection installation is often a smart 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. It also helps improve system performance and reduce the risk of expensive repairs to home heating and cooling equipment.
