Homeowners often think power surges are limited to lightning storms. While lightning is 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 surges don’t just damage televisions and computers. These surges can cause HVAC electrical damage because today’s heating and cooling systems rely on sophisticated electronic components. Thankfully, HVAC surge protection can help safeguard 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 in your home’s wiring. While it lasts only a fraction of a second, it still can damage electronic components. 

Lightning remains the most well-known cause, but many electrical surges begin much closer to home. Utility companies regularly switch power on the electrical grid, and power can also surge when electricity is restored after an outage. Major 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. 

While a single large surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and cooling equipment over time, limiting their lifespan. 

Why Modern HVAC Systems Are More Vulnerable Than Ever 

Many of today’s heating and cooling systems use sophisticated electronics to improve comfort and energy efficiency. Even though hese advanced features offer many benefits, they also make equipment more vulnerable to damage from voltage spikes, increasing the importance of HVAC electrical protection. 

Some of the most at-risk HVAC components to power surges include: 

  • Circuit boards. They serve 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 vulnerable 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 efficient operation. 
  • Inverter technology. Variable-capacity HVAC systems rely on sophisticated electronics that benefit from surge protection. 

Which HVAC Components Are Most at Risk? 

Damage from voltage spikes can cost hundreds or even thousands to repair. Installing whole-house surge protection helps minimize the risk of unexpected failures and major HVAC repair after electrical surge incidents. 

HVAC components that are frequently damaged by power surges in Newport include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • Compressors. An HVAC compressor is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors responsible for circulating conditioned air throughout your home. 
  • Capacitors. Power surges may weaken or damage these components, affecting system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after repeated voltage spikes. 
  • Electronic heat pump components. Heat pumps rely on multiple electronic components which are vulnerable to surges. 

Whole-Home Surge Protection vs. Power Strips 

Many homeowners 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 set up right at your home’s electrical panel. Rather than protecting only one outlet, the system helps safeguard major appliances and electronics throughout your house, including your HVAC equipment. 

Benefits of Whole-Home Surge Protection 

Using whole-home surge protection is a smart way to protect your HVAC investment while also working to safeguard other valuable electronics throughout your home. 

Benefits of whole-house HVAC surge protection include: 

  • Lower repair expenses. Avoiding surge damage can help avoid expensive HVAC repairs. 
  • Extended HVAC system lifespan. Sensitive components experience less electrical stress over time when properly protected. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-house surge protector also shields appliances, computers and entertainment systems. 
  • Less stress during storms. Surge protection provides added confidence when weather-related power outages occur. 
  • Protection from everyday electrical fluctuations. Minor electrical surges can gradually damage connected HVAC devices. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the frequent summer storms in Newport, lightning protection for your HVAC can help minimize the risk of electrical surge damage. 
  2. Blackouts or flickering lights. Frequent outages and changing voltage levels increase the likelihood of damaging voltage spikes. 
  3. Older electrical systems. Old wiring or obsolete electrical equipment can raise your home’s surge risk. 
  4. Modern heating and cooling equipment. Safeguarding 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 technology. Homes with smart thermostats and other connected devices have more sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

Is HVAC surge protection a good investment? 

Yes. Installing whole-home 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. 

Can a sudden power spike damage an air conditioner? 

It can. A power surge can damage an air conditioning compressor, circuit board and blower motor, leading to costly repairs. Installing AC surge protection can protect your air conditioner from power surges by reducing the impact of voltage spikes before they reach sensitive HVAC components. 

What can cause power surges throughout a home? 

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. Small voltage spikes can gradually wear down HVAC components over time. 

How long does a whole-home surge protector last? 

A whole-house surge protector usually lasts 5 to 10 years, although that 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 need replacement sooner. 

Does a homeowners insurance policy cover damage caused by power surges? 

In some cases, but not all. Homeowners insurance can cover power surge damage, but coverage depends on your policy and what caused the surge. Since coverage and deductibles differ, surge protection installation is often cost-effective way to avoid paying for preventable and expensive HVAC repairs. 

Does surge protection help protect smart thermostats? 

Absolutely. Power surge protection for HVAC helps protect smart thermostats and other connected HVAC components from electrical surges. It also helps improve system longevity and reduce the risk of extensive repairs to modern heating and cooling equipment.
