Five months of Maryville summers add up

Your air conditioner runs from May through September here, and a lot of those afternoons sit around 86°F. That is five straight months of long run times, not just a few hot weeks.

A spring tune-up catches what that kind of runtime wears down. The condenser coil gets checked for the dirt and grime that make it work harder than it should. Refrigerant levels get checked too, since a system low on refrigerant runs longer to cool the same house. Finding these things in May means the system is not straining to make up for them all summer.

5 months: May through September, your air conditioner is on duty
86°F: the average summer afternoon it cools against
16 hail events: in ten years, and hail bends the fins on outdoor coils
107 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 the refrigerant charge, cleans the outdoor coil, and tests the capacitor and contactor in the condenser. Inside, they check the evaporator coil and the condensate drain, since a clogged drain is one of the more common causes of a system shutting itself off. They also check the airflow across the coil and confirm the thermostat is calling for cooling correctly. This is separate from changing the filter, which the homeowner should be doing on their own between visits.
How often does an air conditioner need maintenance?: Once a year, done in spring before the heat sets in. Maryville only needs cooling from May through September, so getting the system checked before that stretch starts means a weak capacitor or a dirty coil gets caught before it has to work a 86°F afternoon. Waiting until the system is already running in the heat means any problem shows up as the house not cooling, not before.
Is AC maintenance worth it?: Yes, mainly because it catches small problems while they are still small. A capacitor that is starting to weaken or a coil that is coated with dirt will still cool the house, just less efficiently, until the day it does not. Maryville also sees real storm weather, 107 damaging wind events and 16 hail events over the last ten years, so a yearly visit is a good time to have the outdoor unit checked for storm damage too.
