Five months of heat, every year

Your air conditioner works from May through September in Cookeville. On summer afternoons that average 85°F, it runs long hours to keep up, and the parts inside it wear during those hours, not while it sits idle the rest of the year.

Putnam County has seen 33 hail events and 81 damaging wind events over the past ten years. A unit sitting outside through storms like that can pick up dents in the fins or debris in the cabinet, either one enough to cut its airflow. A tune-up before the season catches a coil that is losing airflow or a unit that is running harder than it should, before either one leaves you without cooling in the heat.

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 that start the compressor. They also check the condensate drain, since a clogged one backs up and can shut the system down. The filter gets checked too, though that part is easy enough to do yourself between visits.
How often does an air conditioner need maintenance?
Once a year, ideally before the cooling season starts. Cookeville homes run the AC from May through September, so having it checked in spring gives a technician time to catch a weak capacitor or a low refrigerant charge before the first hot afternoon. Skipping a year does not ruin the system, but problems that get caught early are smaller than the ones that get caught once the heat sets in.
Is AC maintenance worth it?
Yes, because most of what causes a system to fail on a hot day is something a technician can catch ahead of time. A dirty coil makes the compressor work harder in the heat, and a weak capacitor can leave it unable to start at all once afternoons reach the mid-80s, which is normal for a Cookeville summer. Maintenance matters here for another reason too. With 33 hail events and 81 damaging wind events recorded in this area over the past ten years, an outdoor unit takes a beating, and a yearly check is when bent fins or storm debris in the coil usually get found.
