When severe weather and AC components come together, damage may be the result. Central air conditioners are sturdy; designed and engineered to resist exposure to common factors such as heavy rain. Nevertheless, other risks associated with summer severe weather and AC could potentially shut down HVAC units in certain circumstances.

Like most factors that may pose a hazard to your property, advance preparation is the best preventative measure when seasonal factors such as thunderstorms and hurricanes threaten. Here are some steps you can take to minimize the risk factors of severe weather and AC.

• Cover the outdoor unit. The outdoor component of a central AC system typically resists most rainfall, even in severe weather. However, other mishaps — particularly large broken limbs, a falling tree, or even heavy hail — may damage the fan or other parts of the outdoor condenser unit. Commercially available AC covers are thick fabric and offer some protection from these incidents. Remember to never run the AC system while the cover is still installed on the outdoor unit.
• Secure all heavy objects. Secure (or store indoors) any objects in the yard that could become airborne in high winds and impact the outdoor AC unit. This would include patio furniture, large outdoor umbrellas, barbecue grills, etc.
• Shut off power to the central AC. Damage to outdoor AC components may occur if the units are powered up during severe weather. Identify the circuit breakers that control power to outdoor and indoor AC components and mark them so they can be turned off readily. These circuits are usually dedicated to AC components only so they may be turned off without affecting other electrical components inside the house.
• Invest in a dedicated surge protector for the air conditioner. Power surges on the grid frequently occur during severe weather. A surge suppressor installed at the main circuit board — or at the individual AC unit — will detect a damaging power surge and disconnect the component to protect it from high voltage.

It’s the season when severe weather and AC components don’t get along well together. For more information to protect your investment, talk to the pros at Jackson & Sons.
