Two short months, and a lot of weather in between

Your air conditioner in Lewiston only runs in July and August, with afternoons averaging 77°F. That is a short stretch, but the unit still sits outside all year through wind and hail, whether it is running or not. Androscoggin County has logged 47 damaging wind events and 17 hail events over the past ten years, with hail up to 1.75 inches.

Wind can knock a unit out of level or loosen its connections. Hail that size can bend the thin fins on the outdoor coil, and a bent coil does not announce itself, it just makes the system work harder to move air across it. A tune-up before the season checks the coil, the refrigerant charge, and the electrical connections, so problems that built up over the idle months get caught before the first hot week asks the system to work.

2 months: July through August, your air conditioner is on duty
77°F: the average summer afternoon it cools against
17 hail events: in ten years, and hail bends the fins on outdoor coils
47 wind events: in ten years, and wind drives debris into outdoor units

Book your AC tune-up in June, before homes here start needing cooling in July.

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 level, cleans the outdoor coil, and tests the capacitor and contactor. They also check the condensate drain for clogs and confirm the system is cycling on and holding the temperature it's set to. Coming into cooling season with only 2 months of real heat load here, a clean coil and a properly charged system are what let the unit keep up on the hot afternoons.
How often does an air conditioner need maintenance?: Once a year is enough for most systems. The best time is before the weather turns warm, so any issue gets caught before the unit has to work. With summer afternoons here averaging 77°F, the system isn't under extreme strain, but a yearly check still catches a weak capacitor or low refrigerant before it causes a breakdown.
Is AC maintenance worth it?: Yes. A yearly check catches the small failures, a worn capacitor, a dirty coil, a clogged drain, before they leave you without cooling. It also matters here because of the weather this area sees. Ten years of records show 17 hail events and 47 damaging wind storms, and a maintenance visit is when a technician would spot a bent fin or debris in the unit from one of those storms before it turns into a bigger repair.
