Homeowners often think power surges are limited to lightning storms. While lightning is definitely one cause, it’s far from 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. They can also cause HVAC electrical damage because modern heating and cooling systems rely on highly sensitive electronic components. Fortunately, 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 sudden spike in electrical voltage that travels through your home’s wiring. While it lasts only a fraction of a second, it can damage electronic components. 

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. Sometimes, loose wiring or other home electrical issues contribute to surges. 

Though a single significant surge can cause immediate damage, smaller surges 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 advanced electronics to improve comfort and energy efficiency. Even though hese advanced features offer many benefits, they can make equipment more sensitive to voltage spikes, increasing the importance of HVAC electrical protection. 

Some of the most vulnerable 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. Connected thermostats contain delicate electronics that control your HVAC equipment. 
  • Communication systems. Many newer heating and air conditioning systems use electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter technology. Variable-capacity HVAC systems rely on sophisticated electronics that benefit from surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components most vulnerable to power surges in Marshalltown include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • Airconditioner compressors. An HVAC compressor is one of the highest-priced parts of an air conditioner or heat pump to replace. 
  • Blower motors.Electrical surges 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. Electronic thermostats can malfunction after repeated voltage spikes. 
  • Electronic heat pump components. Modern heat pumps use multiple electronic components that are particularly vulnerable to surges. 

Comparing Whole-Home Surge Protection to Power Strips 

Many people use surge-protecting power strips for computers and televisions, but these plug-in devices don’t protect your furnace or air conditioner. For HVAC system protection, whole-home surge protection offers greater coverage and 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 the house, including your heating and cooling equipment. 

Benefits of Whole-Home HVAC 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. Sensitive components experience reduced electrical stress over time when equipped with surge protection. 
  • Protection for household electronics. 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. 
  • Protectionagainst everyday electrical fluctuations. Small voltage spikes can gradually damage electronic HVAC equipment. 

5 Signs It’s Time to Consider Surge Protection 

  1. Regular summer storms. Given the powerful summer storms in Marshalltown, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Frequent power outages or flickering lights. Ongoing power interruptions and electrical fluctuations increase the likelihood of power surges. 
  3. Older electrical systems. Old wiring or outdated electrical equipment can raise your home’s surge risk. 
  4. High-efficiency HVAC equipment. Protecting a high-efficiency heating and cooling system by installing whole-home surge protection is often more affordable than repairing or replacing damaged components. 
  5. Connected home technology. Homes with smart thermostats and other connected devices have additional sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Absolutely. Whole-home surge protection is often worth the 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.

It can. A power surge can damage an air conditioning compressor, circuit board and blower motor, which can cause costly repairs. AC surge protection helps protect your air conditioner from power surges by preventing the surges from reaching 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.

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 properties that experience frequent storms or utility power fluctuations may require replacement sooner.

It can. Homeowners insurance sometimes cover power surge damage, but coverage depends on your policy and the reason for the surge. Because deductibles and coverage vary, surge protection installation is often a smart way to help prevent expensive HVAC repairs.

Yes. Power surge protection for HVAC helps safeguard smart thermostats and other connected HVAC components from electrical surges. Surge protection may also improve system lifespan and reduce the risk of expensive repairs to home heating and cooling equipment.
