Many people think power surges are limited to lightning storms. Although lightning is one cause, it isn’t the only one.  Major appliances turning on and off, electrical grid switching, power outages and restoration can all create voltage spikes inside your home. 

These surges don’t just damage televisions and computers. They can also cause HVAC electrical damage because current heating and cooling systems rely on highly sensitive electronic components. Thankfully, 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 home power surge is a short spike in electrical voltage running through your home’s wiring. While it lasts only a fraction of a second, it can damage household electronics, including HVAC equipment. 

Lightning remains 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 voltage can also spike when electricity is restored after an outage. Large appliances like refrigerators or HVAC systems can also create small voltage fluctuations when they cycle on and off. Sometimes, loose wiring or other home electrical issues can cause surges. 

Though a single significant surge can cause immediate damage, repeated minor surges can slowly wear down heating and air conditioning systems over time, shortening their lifespan. 

Why Modern HVAC Systems Need More Surge Protection Than Ever 

Today’s heating and cooling systems use advanced electronics to improve comfort and energy efficiency. Although these technologies 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 brief or small voltage spikes. 
  • Energy-efficient variable-speed motors. Variable speed motors rely on electronic controls that are vulnerable to electric surges. 
  • Smart thermostats. Smart home devices are made with 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. 
  • Inverter technology. Variable-capacity HVAC systems rely on 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 or replace. Installing whole-home surge protection helps lower the risk of unexpected failures and expensive HVAC repair after electrical surge incidents. 

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

  • Control boards:Installing a whole-house surge protector protects your HVAC control board’s main. 
  • Airconditioner 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 that circulate conditioned air throughout your home. 
  • HVACcapacitors. Surges can weaken or damage these components, affecting system startup and performance. 
  • Smartthermostats. Electronic thermostats can malfunction after repeated 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 these plug-in devices don’t protect your furnace or air conditioner. For complete HVAC system protection, whole-home surge protection offers more comprehensive coverage and long-term 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-Home Surge Protection 

Adding 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-home HVAC surge protection include: 

  • Fewer repair costs. Preventing surge damage can help avoid expensive HVAC repairs. 
  • Extended HVAC system lifespan. vulnerable technological components experience lower electrical stress over time when properly protected. 
  • Protection of homeelectronics. In addition to protecting your HVAC, whole-home surge protection also safeguards appliances, computers and entertainment systems. 
  • Less stress during storms. You’ll have added confidence when severe weather strikes. 
  • Protectionagainst everyday electrical fluctuations. Even small, routine surges can gradually damage connected HVAC devices. 

5 Signs Your Home Could Benefit from Surge Protection 

  1. Frequent storms. Given the frequent summer storms in Winnipeg, lightning protection for your HVAC can help reduce the risk of electrical surge damage. 
  2. Frequent power outages or flickering lights. Frequent outages and electrical fluctuations increase the likelihood of electrical surges. 
  3. Older electrical systems. Old wiring or obsolete electrical equipment can add to your home’s surge risk. 
  4. High-efficiency HVAC equipment. Shielding a high-efficiency heating and cooling system with a surge protector 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.
