Five months of hard running, every year

Your air conditioner works from May through September here, with summer afternoons averaging 87°F. That is five straight months where the system runs long hours just to keep up, and the compressor and fan motor do not get much rest in between.

A tune-up before that stretch checks the parts that wear from long run times, the capacitor, the contactor, the fan motor, and looks for a weak refrigerant charge or a dirty coil that makes the whole system work harder than it needs to in that heat. Finding a weak part before the heat sets in means it gets fixed before it fails outright.

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, and tests the capacitor and contactor in the outdoor unit. They also check the evaporator coil, change or check the filter, and confirm the system cycles on and off the way it should. That check catches a weak capacitor or a dirty coil before it fails on an afternoon here pushing 87°F.
How often does an air conditioner need maintenance?
Once a year, before cooling season starts. Here that means getting it done ahead of May, since the unit runs from then through September. A yearly check is when a technician finds the parts that wear, like the capacitor, before they quit in the middle of summer.
Is AC maintenance worth it?
Yes, because most breakdowns trace back to something a maintenance visit would have caught, like a failing capacitor or a coil so dirty the system can't shed heat. That matters here, where the system has to run through afternoons averaging 87°F all summer. Skipping the check doesn't save the wear, it just means finding out about it on the hottest day.
