Today’s summer conditions allow us to use our air conditioning units for better indoor comfort. The weather patterns we experience at this time of the year create thunderstorms, however, and when this happens it would be best to turn your air conditioning off right away. Fortunately, such storms usually result in a drop in temperature and humidity, allowing you the relief of cool outdoor air to get you by until it’s safe to turn the AC back on.
Connolly Heating and Air Conditioning, one of the top local HVAC companies, explains the risks of operating your air conditioner during a thunderstorm.
The Effect of Lightning
While rare, it is possible for lightning to strike your home’s exterior. When this happens, a significant power surge will make its way through your electrical system, especially if lightning strikes the point on your roof where the utility lines connect to your home. An immense amount of energy then flows through your home’s wiring before the breakers trip. This surge is enough to damage an AC unit—or any appliance, really—that’s plugged into an outlet and in operation.
Deconstructing AC Damage
Such an unfortunate event would render your HVAC system quite useless. For one, the energy is so strong that it can melt the metal prongs of the plug. Also, the equipment’s interior components are filled with circuitry sensitive to high levels of electrical current, which when damaged requires extensive air conditioner repair or replacement.
Protecting Your AC Unit
A protection system can help prevent damage to your AC unit, especially in the event of a thunderstorm. Lighting rods installed on your roof along with ground rods provide an alternate path for lightning to reach the ground that’s away from your home’s electrical system. Even so, they’re not guaranteed to be absolutely effective at preventing surges, which means turning off your AC during a thunderstorm is still the best idea.
