Homeowners often think power surges occur only during 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 electrical surges inside your home.
These electrical surges don’t just threaten televisions and computers. They may also cause HVAC electrical damage because today’s heating and cooling systems rely on sophisticated electronic components. The good news is 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 sudden spike in electrical voltage in your home’s wiring. While it lasts only a fraction of a second, it still can damage electronic components.
Lightning is the most well-known cause, but many electrical surges begin 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 brief voltage fluctuations when they cycle on and off. It’s also possible that loose wiring or other home electrical issues contribute to surges.
Although one major power surge can cause immediate damage, repeated minor surges can slowly wear down heating and air conditioning systems over time, limiting their lifespan.
Why Modern HVAC Systems Require Better Surge Protection
Many of today’s heating and cooling systems use sophisticated electronics to improve comfort and energy efficiency. Although these technologies offer many benefits, they can also make equipment more vulnerable to damage from voltage spikes, increasing the importance of HVAC electrical protection.
HVAC parts that are especially sensitive to power surges include:
- Circuit boards. They serve as the system’s control center and can be damaged by even minimal voltage spikes.
- Variable-speed motors. These advanced motors rely on electronic controls that are sensitive to electric surges.
- Smart thermostats. Smart home devices are made with delicate electronics that communicate with your HVAC equipment.
- Communication systems. Many newer heating and air conditioning 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 benefit from surge protection.
Which HVAC Components Need the Most Protection?
Damage from electrical surges can cost hundreds or even thousands of dollars to fix. Installing whole-house 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 Pella include:
- Control boards:Protecting your HVAC system’s control board safeguards its primary.
- HVAC compressors. This component is one of the highest-priced 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.
- Capacitors. Electrical surges can weaken or damage these components, impacting system startup and performance.
- Smartthermostats. Electronic thermostats can malfunction after multiple voltage spikes.
- Heat pumpelectronics. Heat pumps rely on multiple electronic components that are particularly vulnerable to surges.
Comparing Whole-Home Surge Protection to Power Strips
Homeowners commonly use surge-protecting power strips for computers and televisions, but power strips don’t protect your HVAC system. For HVAC system protection, whole-home surge protection offers greater coverage and 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, it can help safeguard major appliances and electronics throughout your entire house, including your heating and cooling equipment.
Benefits of Whole-Home Surge Protection
Installing 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:
- Reduced repaircosts. Avoiding surge damage can help reduce expensive HVAC repairs.
- Extended HVAC system lifespan. Sensitive components experience lower electrical stress over time when protected correctly.
- Home electronics protection. In addition to protecting your HVAC, a whole-home surge protector also shields appliances, computers and entertainment systems.
- Added confidence during severe weather. Homeowners gain added confidence when severe storms strike your area.
- Protectionagainst everyday electrical fluctuations. Even small, routine surges can gradually damage connected HVAC devices.
5 Signs You May Need Surge Protection
- Severe weather. Given the powerful summer storms in Pella, lightning protection for your HVAC can help lower the risk of surge-related damage.
- Power outages or flickering lights. Repeated outages and electrical fluctuations increase the likelihood of power surges.
- Aging electrical systems. Old wiring or obsolete electrical equipment can add to your home’s surge risk.
- Expensive HVAC equipment. Protecting a high-efficiency heating and cooling system by installing whole-home surge protection is often far less costly than repairing or replacing damaged components.
- Smart home technology. Homes with Wi-Fi thermostats and other connected devices have additional sensitive electronics to protect.
