Two months of real heat, and a lot of storms in between

Your air conditioner only has to work hard in July and August here, with afternoons averaging around 80°F. That is a short season, but it is also a short window for something to go wrong before you notice, since the unit sits idle most of the year and then gets asked to run every day.

Johnson County has logged 49 hail events and 110 damaging wind events over the past ten years, with hail up to 2.75 inches. That kind of weather bends fins on the outdoor coil and can knock loose the wiring and connections inside the cabinet. A tune-up checks the coil, the fins, and the electrical connections before the first hot week finds the problem for you.

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

What does AC maintenance include?
A contractor checks the refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and clear the condensate drain, since that drain clogs easily and backs water up into the house. They confirm the thermostat is calling for cooling properly and clean or replace the filter if it needs it. The goal is to find a weak part before it fails during the hot stretch you actually need the system.
How often does an air conditioner need maintenance?
Once a year, before the weather turns warm. Buffalo only asks the system to run in July and August, but the coil and electrical parts sit outside and age all year regardless. A spring check catches a failing capacitor or a dirty coil before the two months you need cooling most.
Is AC maintenance worth it?
Yes, mainly because it catches small failures before they turn into no-cool days. A capacitor starting to weaken, a coil caked with a season of dirt, a drain slowly clogging, these show up in a check and cost nothing to find. Buffalo's cooling season is short, just two months, so a system that quits in July can mean waiting on a part with little summer left to use it.
