Two months of work, then a long rest

Your air conditioner in Vineyard Haven only earns its keep in July and August, with afternoons averaging around 77°F. That is not a hard summer, but the unit sits idle the other ten months while dust settles on the coil and the fan.

A tune-up before summer catches what that idle time does to it. A dirty coil makes the system work harder to move the same heat out of the house. With only two months to do its job, you want it running right from the first hot day, not halfway through the season it has.

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 condenser coil, and tests the capacitor and the fan motor. They also check the electrical connections and make sure the condensate drain isn't clogged. Indoors, they check the evaporator coil and change or clean the filter if it needs it. Each of these affects how well the system cools and how long it lasts.
How often does an air conditioner need maintenance?
Once a year, before the weather turns warm. Here that means getting it done before July, since your system only runs through July and August. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown during the two months you actually need the cooling.
Is AC maintenance worth it?
Yes, because most AC failures come from small problems that get worse over time. A dirty coil makes the compressor work harder, and a weak capacitor can fail outright on the first hot afternoon. With only two months of real cooling season here, you want the system working the first time you turn it on, not stalled out on a 77 degree afternoon while you wait for a repair.
