Many people think power surges are limited to lightning storms. While lightning is definitely 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. These surges can cause HVAC electrical damage because modern heating and cooling systems rely on sophisticated electronic components. Fortunately, HVAC surge protection can help shield one of your home’s biggest investments and reduce the risk of expensive repairs. 

What Are Power Surges  

A power surge in your home is a short spike in electrical voltage that travels through your home’s wiring. While it lasts only a fraction of a second, it still can damage household electronics, including HVAC equipment. 

Lightning is the most well-known cause, but many electrical surges begin much closer to home. Utility companies regularly switch power on the electrical grid, and voltage can also spike when electricity is restored after an outage. Large 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. 

While a single large surge can cause immediate damage, smaller, repeated voltage spikes can slowly wear down heating and cooling equipment over time, limiting their lifespan. 

Why Modern HVAC Systems Require Better Surge Protection 

Many of 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, increasing the importance of HVAC electrical protection. 

HVAC parts that are especially sensitive 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. 
  • Energy-efficient variable-speed motors. These energy-saving motors rely on electronic controls that are susceptible to electric surges. 
  • Smart thermostats. Smart home devices are made with 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. Systems with variable-capacity operation use sophisticated electronics that are better protected with surge protection. 

Which HVAC Components Are Most Vulnerable to Power Surges? 

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

HVAC components that are frequently damaged by power surges in Cocoa include: 

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Airconditioner compressors. The compressor is one of the highest-priced 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. 
  • HVACcapacitors. Surges can weaken or damage these components, affecting system startup and performance. 
  • Thermostats and Smart Home Technology. A smart thermostat can malfunction after multiple voltage spikes. 
  • Electronic heat pump components. Heat pump systems depend on multiple electronic components that are particularly vulnerable to surges. 

Whole-Home Surge Protection vs. Power Strips 

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

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

Benefits of Whole-Home Surge Protection 

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

Benefits of whole-home HVAC surge protection include: 

  • Lower repair expenses. Reducing surge damage can help reduce expensive HVAC repairs. 
  • Longer-lasting HVAC equipment. vulnerable technological components experience lower electrical stress over time when properly protected. 
  • Home electronics protection. In addition to protecting your HVAC, a whole-home surge protector also helps protect appliances, computers and entertainment systems. 
  • Added confidence during severe weather. Homeowners gain added confidence when severe storms strike your area. 
  • Protection from everyday electrical fluctuations. Even small, routine surges can gradually damage connected HVAC devices. 

5 Signs It’s Time to Consider Surge Protection 

  1. Frequent storms. Given the frequent summer storms in Cocoa, lightning protection for your HVAC can help lower the risk of surge-related damage. 
  2. Frequent power outages or flickering lights. Ongoing power interruptions and electrical fluctuations increase the likelihood of electrical surges. 
  3. Outdated home wiring. Old wiring or obsolete electrical equipment can increase your home’s surge risk. 
  4. High-efficiency HVAC 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. Smart home technology. Homes with Wi-Fi thermostats and other connected devices have more sensitive electronics to protect.
