Intense thunderstorms produce lightning, which can pose a major risk to your HVAC system. Workers or other manmade causes may also result in power outages and surges that affect your heater or air conditioning. Not only does your HVAC system require electricity to function, but today’s heating and cooling appliances incorporate numerous electrical components that can be damaged by power outages and surges as well. Although you cannot control power surges, you can take a few precautions to prevent them from harming your HVAC equipment.
 
Turn Off Your System
One of the easiest ways to prevent power surges from harming your HVAC system is to turn off the system at the thermostat or the circuit breaker (or both) before a storm occurs. Your HVAC equipment can be more extensively damaged by a power surge if it is on and operating at the time of the surge. Thus, turning your system off will reduce any damage that could occur if your heater or air conditioning is operating during a storm. Even if you only use room air conditioners or window units, turn them off and unplug them to prevent a power surge from causing damage.
 
Use Surge Protection
Surge protection provides a buffer for excess electricity if a power surge does occur. Whole-home surge protection is a big step toward protecting your HVAC system and your other appliances in case of a power surge. This type of surge protection is installed at the point of entry for your main power line and provides protection for every appliance in your home—including your HVAC system. Additionally, you should use power strips that incorporate surge protection in each of your outlets. Make sure your HVAC equipment is plugged into one such power strip and that the surge protection in the strip is functioning properly.
 
Utilize Time-Delay Technology
Power surges can also occur following a power outage as the grid stabilizes, during which time brief power spikes can persist for a few minutes after power is restored. If your HVAC equipment starts up immediately upon the restoration of power, these lingering power spikes could still cause damage. Installing a thermostat that incorporates time-delay technology will automatically prevent your HVAC system from turning on the instant power is restored. Time-delay technology will keep your system off for a brief period of time, usually five minutes, to allow the power grid time to stabilize before reactivating your heating or cooling system.
