Three months of work a year, then months of sitting still

Your air conditioner in Waterbury only runs June through August. Summer afternoons here average 82°F, warm enough to put real hours on the compressor but not the kind of heat that pushes a system past what it can handle.

The harder part is the time it spends off. A refrigerant leak or a weak capacitor can sit unnoticed while the system is idle, and you find out the day you need cooling most. A tune-up before summer catches that kind of problem while the system is still off, not after it has already let you down.

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

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

Connecticut requires HVAC contractors to hold a state license.

The Department of Consumer Protection tests and records the contractor before issuing the license, and keeps that on file. It covers the contractor as a whole, not the specific job at your house.

For an AC maintenance visit, that license is what stands behind the person working on your system. If the work involves opening the refrigerant side, the technician also needs EPA Section 608 certification, which is a federal requirement in every state and separate from the Connecticut license.

What does AC maintenance include?: A technician checks refrigerant charge, cleans the condenser coil outside, and checks the evaporator coil in the air handler. They test the capacitor and contactor, check amp draw on the compressor and fan motor, and check the condensate drain for clogs. They also check the thermostat calling for cool correctly and check airflow across the coil. Your filter should already be clean before the visit, since a dirty one throws off some of these readings.
How often does an air conditioner need maintenance?: Once a year, before the season it works hardest. Here that means getting it checked before June, since the system only runs hard through the summer months. A yearly check catches a weak capacitor or a low refrigerant charge before an 82°F afternoon turns it into a no-cool call.
Is AC maintenance worth it?: Yes, because most of what fails on an air conditioner fails slowly. A capacitor weakens, a coil gets coated with dust, a refrigerant charge drops a little at a time. A yearly check catches these while the system is still running, not after it stops on a hot afternoon. With only three months of real cooling season here, a system that is not checked can go a long time before anyone notices it is working harder than it should.
