Two months of real work, then months sitting idle

Your air conditioner in New Bedford only has to earn its keep in July and August, with afternoons averaging 81°F. That is not a hard summer, but it is a short one, and the unit spends the other ten months sitting outside doing nothing.

A unit that sits idle that long can develop problems before it ever runs. Bristol County has seen 282 damaging wind events and 20 hail events over the past ten years, with hailstones up to 1.5 inches. Wind can bend the thin fins on the outdoor coil or knock debris into the cabinet, and hail can dent the coil itself. None of that shows up while the unit is off. A tune-up before the weather turns catches a bent coil or a fin packed with debris before the first hot day asks the system to run.

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 condenser coil, and tests the capacitor and electrical connections. They also check the blower for dirt buildup and confirm the thermostat is calling for cooling correctly. A dirty condenser coil makes the system work harder to move the same amount of heat, so cleaning it is one of the bigger parts of the visit. Part of the visit is also a look at the drain line, since a clogged one backs up and can leak into the house.
How often does an air conditioner need maintenance?
Once a year, ideally before the season it works hardest. Here that means getting it checked before July, since your air conditioner only runs hard for about two months, July and August, when afternoons average 81°F. A yearly check catches a weak capacitor or low refrigerant before it fails on the one stretch of summer you actually need it.
Is AC maintenance worth it?
Yes, because most breakdowns start as a small problem that a technician can catch while it is still cheap to fix. A weak capacitor or a dirty coil does not usually announce itself, it just makes the system run longer and less effectively until it stops. With only two months of real cooling season here, a system that fails in July has no slack time to get it fixed before you need it again.
