Six months of heat on your air conditioner

Your air conditioner runs from May through October here, six months straight. Summer afternoons average 89°F, and on those days the compressor is cycling on and off for hours just to hold the house at temperature.

A tune-up during that stretch checks the refrigerant charge, the condenser coil, and the electrical connections that carry the load. Catching a problem in one of those before the hottest part of summer is the difference between a repair and a system that quits when you need it most.

6 months: May through October, your air conditioner is on duty
89°F: the average summer afternoon it cools against
20 hail events: in ten years, and hail bends the fins on outdoor coils
304 wind events: in ten years, and wind drives debris into outdoor units

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 refrigerant pressure, cleans the outdoor coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the drain line that carries condensation away, since a clogged drain line can back up and cause water damage. They also check the thermostat calls and cycle the system to see that it starts, runs, and shuts off the way it should. On a system that runs from May through October here, catching a weak capacitor or a dirty coil before the season gets going matters, since those are the months the system can least afford to struggle.
How often does an air conditioner need maintenance?: Once a year is standard, ideally in spring before the cooling season starts. Here that means getting it done before May, since the system will run steadily through October with afternoons averaging 89°F. A yearly check catches a failing capacitor or a low refrigerant charge while it is a small problem, not a breakdown in the middle of summer.
Is AC maintenance worth it?: Yes. A dirty coil or a weak capacitor makes the compressor work harder, and that is what shortens its life or leads to a breakdown mid-summer. Regular maintenance also gives a technician a chance to catch a refrigerant leak or a worn part before it takes the system down entirely. With hail and high wind both on record here, a yearly check is also a good time to have the outdoor unit looked over for any damage to the coil or the cabinet that might not be obvious otherwise.
