Many homeowners think power surges occur only during lightning storms. While lightning is 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 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 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 is a brief spike in electrical voltage that travels through your home’s wiring. Although it lasts only a fraction of a second, it still can damage household electronics, including HVAC equipment. 

Many people know lightning is the most well-known cause, but many surges happen much closer to home. Power companies frequently adjust power on the electrical grid, and power can also surge when electricity is restored after an outage. Major appliances like refrigerators or AC units can also create brief voltage fluctuations when they cycle on and off. In some cases, loose wiring or other home electrical issues contribute to surges. 

Although one major power surge can cause immediate damage, repeated minor surges can slowly wear down heating and air conditioning systems over time, reducing their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Today’s heating and cooling systems use high-tech 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, highlighting the importance of HVAC electrical protection. 

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

  • Electronic circuit boards. They function as the system’s control center and can be damaged by even very small voltage spikes. 
  • Variable-speed motors. These advanced motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that communicate with your HVAC equipment. 
  • HVAC system communication controls. Modern heating and cooling systems use electronic communication between indoor and outdoor units for efficient operation. 
  • Inverter-driven technology. Variable-capacity HVAC systems use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most at Risk? 

Damage from voltage spikes can cost hundreds or even more to repair. Installing whole-house surge protection helps reduce the risk of unexpected failures and expensive HVAC repair after voltage spike incidents. 

HVAC components most vulnerable to power surges in Des Moines 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 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. Electrical surges can weaken or damage these components, impacting system startup and performance. 
  • Thermostats and Smart Home Technology. These devices may malfunction after repeated voltage spikes. 
  • Heat pumpelectronics. Heat pump systems depend on multiple electronic components that can be vulnerable to surges. 

Which is Better for My Home: Whole-Home Surge Protection or Power Strips? 

Homeowners commonly use surge-protecting power strips for computers and televisions, but those devices don’t protect your heating and cooling system. For HVAC system protection, whole-home surge protection offers broader coverage and lasting value. 

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

Benefits of Whole-House Surge Protection 

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

Benefits of whole-house HVAC surge protection include: 

  • Lower repair expenses. Reducing surge damage can help reduce expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Sensitive components experience reduced electrical stress over time when protected correctly. 
  • Protection for household electronics. In addition to protecting your HVAC, a whole-house surge protector also safeguards appliances, computers and entertainment systems. 
  • Greater peace of mind duringstorms. Homeowners gain added confidence when severe weather strikes. 
  • Defense against everyday electrical fluctuations. Minor electrical surges can gradually damage your HVAC system. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Regular summer storms. Given the frequent summer storms in Des Moines, lightning protection for your HVAC can help reduce the risk of power surge damage. 
  2. Blackouts or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of electrical surges. 
  3. Outdated home wiring. Old wiring or outdated electrical equipment can increase 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 less expensive than repairing or replacing damaged components. 
  5. Connected home technology. Homes with smart thermostats and other connected devices have even more sensitive electronics to protect.

Frequently Asked Questions About Whole-Home Surge protection for HVAC 

Is a whole-house surge protection beneficial for an HVAC system? 

Yes. Installing whole-home surge protection is typically a worthwhile investment because it helps protect expensive HVAC equipment. The cost of installing surge protection is typically much lower than repairing or replacing damaged HVAC components, helping extend the life of your home comfort system. 

Can a sudden power spike damage an AC unit? 

Yes. A power surge can damage your AC unit’s compressor, circuit board and blower motor, resulting in costly repairs. AC surge protection helps protect your air conditioner from power surges by reducing the impact of voltage spikes before they reach sensitive HVAC components. 

What causes power surges throughout a home? 

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

How long does a whole-home surge protector last? 

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

Does homeowners insurance cover damage caused by power surges? 

It depends. Homeowners insurance may cover power surge damage, but coverage depends on your policy and the reason for 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 a surge protector help protect smart thermostats? 

Absolutely. Power surge protection for HVAC helps shield smart thermostats and other connected HVAC components from damaging voltage spikes. It can also improve system longevity and reduce the risk of costly repairs to modern heating and cooling equipment.
