Homeowners often think power surges are limited to lightning storms. While lightning is one cause, it’s far from the only one. Utility switching, power outages/restoration and even large appliances cycling on and off can all create voltage spikes inside your home. 

These electrical surges don’t just threaten televisions and computers. They can also cause HVAC electrical damage because modern heating and cooling systems rely on sophisticated electronic components. Fortunately, HVAC surge protection can help safeguard one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Is a Power Surge  

A power surge is a brief spike in electrical voltage running through your home’s wiring. Although it lasts only a fraction of a second, it may damage household electronics, including HVAC equipment. 

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 electrical surges also can happen when electricity is restored after an outage. Household appliances like refrigerators or HVAC systems can also create minor voltage fluctuations when they cycle on and off. Sometimes, loose wiring or other home electrical issues lead to surges. 

Though a single significant surge can cause immediate damage, repeated minor surges can slowly wear down HVAC components over time, reducing their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Modern 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 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: 

  • Electronic circuit boards. They serve as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Variable-speed motors. These energy-saving motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that control your HVAC equipment. 
  • Communication systems. Modern heating and cooling systems use electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Variable-capacity inverter technology. Variable-capacity HVAC systems rely on 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 fix. Installing whole-home surge protection helps reduce the risk of unexpected failures and major HVAC repair after power surge incidents. 

HVAC components most vulnerable to power surges in Greensburg include: 

  • Control boards:The HVAC system’s control board contains essential operating controls, which can be badly damaged by surges. 
  • HVAC compressors. This component is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Electrical surges can damage motors responsible for circulating conditioned air throughout your home. 
  • HVAC system capacitors. Electrical surges can weaken or damage these components, impacting system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats can malfunction after multiple voltage spikes. 
  • Electronic heat pump components. Heat pumps rely on multiple electronic components which are vulnerable to surges. 

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

Many people use surge-protecting power strips for computers and televisions, but those devices don’t protect your heating and cooling system. For complete 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. Instead of regulating electricity to only one outlet, it helps safeguard major appliances and electronics throughout the house, including your heating and cooling equipment. 

Benefits of Whole-House Surge Protection 

Using 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-house HVAC surge protection include: 

  • Fewer repair costs. Reducing surge damage can help prevent expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Sensitive components experience lower 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 severe weather strikes. 
  • Protectionagainst everyday electrical fluctuations. Minor electrical surges can gradually damage electronic HVAC equipment. 

5 Signs You May Need Surge Protection 

  1. Severe weather. Given the strong summer storms in Greensburg, lightning protection for your HVAC can help lower the risk of electrical surge damage. 
  2. Power outages or flickering lights. Ongoing power interruptions and voltage fluctuations increase the likelihood of electrical surges. 
  3. Outdated home wiring. Old wiring or substandard electrical equipment can increase your home’s surge risk. 
  4. High-efficiency HVAC equipment. Protecting a high-efficiency heating and cooling system with a surge protector is often more affordable than repairing or replacing damaged components. 
  5. Smart home devices. Homes with Wi-Fi thermostats and other connected devices have more sensitive electronics to protect.

Frequently Asked Questions About HVAC Surge Protection 

Is whole-home surge protection worth it for an HVAC system? 

Yes. 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, helping extend the life of your home comfort system. 

Can a power surge damage an an air conditioning system? 

Absolutely. A power surge can damage an air conditioning compressor, circuit board and blower motor, which can cause major repairs. Installing AC surge protection can protect your air conditioner from electrical fluctuations by reducing the impact of voltage spikes before they reach sensitive HVAC components. 

What are the common causes of power surges inside a home? 

Power surges are most commonly caused by lightning strikes, utility grid switching, power outages, power restoration and large appliances cycling on and off. They can also result from problems within your home’s electrical system. Even small, repeated surges can gradually wear down HVAC components over time. 

How long does whole-home surge protection last? 

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 homes that experience many severe storms or utility power fluctuations may require replacement sooner. 

Does homeowners insurance 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 the cause of the surge. Since coverage and deductibles differ, surge protection installation is often cost-effective way to protect your pocketbook from expensive HVAC repairs. 

Will whole-home surge protection help protect smart thermostats? 

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