Five months of Hendersonville heat wears on a system

Your air conditioner runs from May through September here, and on afternoons that hit 87°F it doesn't get much of a break. The compressor cycles on and off all day to keep up, and that steady work adds up over a season.

Sumner County has also logged 44 hail events and 151 damaging wind events over the past ten years. Hail up to 2 inches can bend the fins on your outdoor unit or dent the cabinet, and high winds can knock it out of level or loosen the electrical connections. A maintenance visit checks the coil and fins for damage, confirms the unit is running the way it should, and catches the kind of wear a summer like this puts on it before it turns into a system that won't keep up on the next 87°F afternoon.

Book your AC tune-up in April, before homes here start needing cooling in May.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.

What does AC maintenance include?: A technician checks the refrigerant charge, cleans the condenser coil, tests the capacitor, and inspects the electrical connections. They also check the airflow across the evaporator coil and make sure the condensate drain isn't clogged. Most of these checks catch small problems, like a weak capacitor or a dirty coil, before they turn into a system that won't cool at all.
How often does an air conditioner need maintenance?: Once a year, ideally before the season it works hardest. Here that means getting it checked before May, since the system runs from May through September and summer afternoons average 87°F. A yearly check keeps the coil clean and the refrigerant charge correct, which is what the system needs to keep up on the hottest days.
Is AC maintenance worth it?: Yes, because it catches the small failures that cause breakdowns during the months you need cooling most. A dirty coil or a weak capacitor won't stop the system right away, but it will make it work harder until it does, usually on a hot afternoon when you need it least. Regular maintenance also gives a technician a chance to spot wiring or refrigerant issues before they become bigger repairs.
