Two months of real work, then months of sitting idle

Your air conditioner in Brockton only earns its keep in July and August, when afternoons average 80°F. That is a short season, but it is not a light one. The system runs hard for two months, then sits shut off and unused the rest of the year.

That idle time is when problems settle in. A capacitor that weakened last summer does not announce itself until the first hot day this year, when the compressor needs it most. Plymouth County has also seen 346 damaging wind events over the past ten years, and enough storms to bring 21 hail events, one leaving a hailstone 1.75 inches across. Wind and hail like that can bend the fins on your outdoor unit or knock the cabinet out of alignment, small damage that goes unnoticed until the unit is asked to run at full load. A tune-up before summer catches a weak capacitor, bent fins, or a low refrigerant charge while there is still time to fix it before the two months you actually need the system.

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 contactor. They also check the thermostat's calling for cool correctly and look at the condensate drain, since a clogged drain can back up and cause water damage. Outside, the coil gets a rinse if it's caked with pollen or grass clippings, and the fan gets checked for wobble or noise.
How often does an air conditioner need maintenance?
Once a year, ideally before the weather turns warm. Homes here only run the AC through July and August, so getting it checked in the spring means it's ready when those two months hit. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown during the only stretch of the year you actually need cooling.
Is AC maintenance worth it?
Yes, because most AC breakdowns trace back to something a checkup would have caught. A dirty coil makes the compressor work harder, and a weak capacitor is one of the most common reasons a unit won't start at all. With summer afternoons here averaging 80°F, catching these issues early means the system is ready when you actually need it, rather than failing on the one hot week of the year.
