Four months of steady heat, every year

Your air conditioner in Kings County sits idle most of the year and then works hard from June through September. Afternoons average 83°F through that stretch, and the unit runs long hours to keep up. That steady run is what wears on it. A unit that starts the season fine can lose refrigerant charge, build up dirt on the coil, or strain a capacitor that was already weak.

A tune-up before the season catches those things while they are still small. A technician checks the refrigerant charge, cleans the coil, and tests the capacitor and other electrical parts before those four months ask them to prove themselves.

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.

What does AC maintenance include?: A technician checks refrigerant pressure, cleans the condenser coil outside, and tests the capacitor and other electrical connections. They also change or check the filter, clear the condensate drain line, and check that the system is actually cooling the air by the right amount. Most of these problems build up slowly and do not show themselves until the system is straining on a hot afternoon.
How often does an air conditioner need maintenance?: Once a year, before the weather turns warm. Here that means getting it done before June, since the system will run steadily from June through September. A yearly check catches a dirty coil or a weak capacitor before it has to work through those four months.
Is AC maintenance worth it?: Yes, because most air conditioner failures trace back to something a technician could have caught, like a dirty coil or a failing capacitor. Summer afternoons here average 83°F, and a system fighting a dirty coil in that heat works harder and wears down faster. Catching those problems in spring means the system starts June in good shape instead of finding out in the middle of it.
