Homeowners often think power surges occur only 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 electrical 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. Thankfully, 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 home power surge is a brief spike in electrical voltage running through your home’s wiring. While it lasts only a fraction of a second, it can damage home electronics. 

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 electrical surges also can happen when electricity is restored after an outage. Major appliances like refrigerators or air conditioners 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, 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. While these features offer many benefits, they can make equipment more at risk of damage from voltage spikes, highlighting the importance of HVAC electrical protection. 

HVAC parts that are especially sensitive to power surges include: 

  • Control boards. They serve as the system’s control center and can be damaged by even minimal voltage spikes. 
  • Variable-speed motors. Variable speed motors rely on electronic controls that are susceptible to electric surges. 
  • Smart thermostats. A smart thermostat uses delicate electronics that control your HVAC equipment. 
  • Electronic communication systems. Modern heating and cooling systems use electronic communication between indoor and outdoor units for energy-efficient operation. 
  • Inverter-driven 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 electrical surges can cost hundreds or even thousands to repair. Installing whole-home surge protection helps reduce the risk of unexpected failures and major HVAC repair after electrical surge incidents. 

HVAC components most commonly affected by power surges in Payson include: 

  • Control boards:Protecting your HVAC system’s control board safeguards its primary. 
  • Compressors. This component is one of the most expensive parts of an air conditioner or heat pump to replace. 
  • Blower motors.Voltage spikes can damage motors responsible for circulating conditioned air throughout your home. 
  • HVACcapacitors. Power surges may weaken or damage these components, impacting system startup and performance. 
  • Thermostats and Smart Home Technology. Electronic thermostats can malfunction after multiple voltage spikes. 
  • Heat pump control electronics. 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? 

Many homeowners use surge-protecting power strips for computers and televisions, but power strips don’t protect your HVAC system. To provide complete HVAC system protection, whole-home surge protection offers more comprehensive coverage and 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 Surge Protection 

Adding 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-house HVAC surge protection include: 

  • Reduced repaircosts. Preventing surge damage can help reduce expensive HVAC repairs. 
  • Longer HVAC equipmentlife. Electronic HVAC components experience lower electrical stress over time when protected correctly. 
  • Protection of homeelectronics. In addition to protecting your HVAC, a whole-home surge protector also safeguards appliances, computers and entertainment systems. 
  • Less stress during storms. You’ll have added confidence when severe weather strikes. 
  • Protection from 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 frequent summer storms in Payson, lightning protection for your HVAC can help minimize the risk of surge-related damage. 
  2. Frequent power outages or flickering lights. Ongoing power interruptions and voltage fluctuations increase the likelihood of damaging voltage spikes. 
  3. Outdated home wiring. Old wiring or obsolete electrical equipment can raise your home’s surge risk. 
  4. Modern heating and cooling 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. Connected home technology. Homes with smart thermostats and other connected devices have more sensitive electronics to protect.
