Many homeowners think power surges only happen during 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 electrical surges inside your home. 

These electric voltage spikes don’t just damage televisions and computers. They can also cause HVAC electrical damage because today’s heating and cooling systems rely on highly sensitive electronic components. Fortunately, HVAC surge protection can help protect one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Are Power Surges  

A power surge is a brief spike in electrical voltage in your home’s wiring. While it lasts only a fraction of a second, it can damage electronic components. 

Lightning is the most well-known cause, but power surges often occur much closer to home. Electric utility providers routinely switch power on the electrical grid, and power can also surge when electricity is restored after an outage. Household appliances like refrigerators or air conditioners can also create small voltage fluctuations when they cycle on and off. Sometimes, 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, reducing their lifespan. 

Why Modern HVAC Systems Require Better Surge Protection 

Today’s heating and cooling systems use advanced electronics to improve comfort and energy efficiency. While these features offer many benefits, they can make equipment more at risk of 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. These act as the system’s control center and can be damaged by even very small voltage spikes. 
  • Variable-speed blower motors. Variable speed motors rely on electronic controls that are sensitive to electric surges. 
  • Smart thermostats. Smart home devices are made with delicate electronics that control your HVAC equipment. 
  • HVAC system communication controls. Modern heating and cooling systems use electronic communication between indoor and outdoor units for reliable operation. 
  • Inverter technology. Systems with variable-capacity operation use sophisticated electronics that work best with surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components most vulnerable to power surges in Magnolia include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Compressors. This component is one of the costliest 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. 
  • HVAC system capacitors. Power surges may weaken or damage these components, affecting system startup and performance. 
  • Smartthermostats. Electronic thermostats can malfunction after repeated voltage spikes. 
  • Electronic heat pump components. Heat pump systems depend on multiple electronic components that are particularly 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 power strips don’t protect your heating and cooling system. To provide complete HVAC system protection, whole-home surge protection offers broader coverage and lasting value. 

A professionally installed whole-house surge protector is set up right at your home’s electrical panel. Rather than protecting only one outlet, it can help safeguard major appliances and electronics throughout your entire house, including your heating and cooling equipment. 

Benefits of Whole-House Surge Protection 

Installing 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. Reducing surge damage can help avoid expensive HVAC repairs. 
  • Extended HVAC system lifespan. Sensitive components experience lower electrical stress over time when equipped with surge protection. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-home surge protector also helps protect 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. Small voltage spikes can gradually damage your HVAC system. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the strong summer storms in Magnolia, lightning protection for your HVAC can help reduce the risk of surge-related damage. 
  2. Blackouts or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of damaging voltage spikes. 
  3. Aging electrical systems. Old wiring or obsolete electrical equipment can add to your home’s surge risk. 
  4. Modern heating and cooling equipment. Shielding a high-efficiency heating and cooling system with a surge protector is often more affordable 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 

Is HVAC surge protection a good investment? 

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

Can an electrical surge damage an air conditioner? 

It can. A power surge can damage your AC unit’s compressor, circuit board and blower motor, which can cause expensive repairs. A surge protector for your AC helps protect your air conditioner from electrical surges by reducing the impact of voltage spikes before they reach sensitive HVAC components. 

What are the common causes of 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. 

What is the average lifespan of a whole-house surge protector? 

Most whole-home surge protectors last 5 to 10 years, although that 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. 

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

It can. 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 a smart way to protect your pocketbook from expensive HVAC repairs. 

Can whole-home surge protection help protect smart thermostats? 

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