Homeowners often think power surges are limited to lightning storms. While lightning is definitely one cause, it’s certainly not the only one. Utility grid activity, restoring power after outages and large household appliances cycling can all create voltage spikes inside your home. 

These surges don’t just pose a risk to televisions and computers. They can also cause HVAC electrical damage because modern heating and cooling systems rely on highly sensitive electronic components. Thankfully, HVAC surge protection can help protect one of your home’s biggest investments and reduce the risk of costly repairs. 

What Are Power Surges  

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 can damage home electronics. 

Many people know 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 electrical surges also can happen when electricity is restored after an outage. Large appliances like refrigerators or HVAC systems 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 surges can slowly wear down heating and cooling equipment over time, shortening their lifespan. 

Why Modern HVAC Systems Require Better Surge Protection 

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 sensitive to 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 brief or small voltage spikes. 
  • Energy-efficient variable-speed motors. These advanced 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. 
  • HVAC system communication controls. 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 at Risk? 

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

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

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • 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 that circulate conditioned air throughout your home. 
  • HVAC system capacitors. Power surges may weaken or damage these components, impacting system startup and performance. 
  • Smartthermostats. A smart thermostat can malfunction after multiple voltage spikes. 
  • Electronic heat pump components. Heat pump systems depend on multiple electronic components which are vulnerable to surges. 

Comparing Whole-Home Surge Protection to Power Strips 

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

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

Benefits of Whole-Home HVAC 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-home HVAC surge protection include: 

  • Lower repair expenses. Preventing surge damage can help reduce expensive HVAC repairs. 
  • Longer HVAC equipmentlife. vulnerable technological components experience reduced electrical stress over time when equipped with surge protection. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-house surge protector also shields appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Surge protection provides added confidence when severe weather strikes. 
  • Defense against everyday electrical fluctuations. Even small, routine surges can gradually damage your HVAC system. 

5 Signs Your Home Could Benefit from Surge Protection 

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

Frequently Asked Questions About HVAC Surge Protection 

Yes. Whole-home surge protection is often a smart 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.

Yes. A power surge can damage an air conditioning compressor, circuit board and blower motor, leading to major repairs. AC surge protection helps protect your air conditioner from power surges 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. Power surges may also stem from 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 properties that experience frequent storms or utility power fluctuations may need replacement sooner.

In some cases, but not all. Homeowners insurance can 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 help prevent expensive HVAC repairs.

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