Three months to get it right

Your air conditioner in Yonkers only gets June through August to do its job. Summer afternoons average 82°F, and the system has to hold that back for three months straight before it gets a break.

A tune-up before summer checks the parts carrying that load. The refrigerant level. The condenser coil. The capacitor that gets the compressor started. A weak capacitor or a coil covered in dust does not always fail outright, it just makes the system work harder to cool the same rooms. Finding that in the spring means the air conditioner is not doing that quiet, slow failing through the only three months it runs.

3 months: June through August, your air conditioner is on duty
82°F: the average summer afternoon it cools against
16 hail events: in ten years, and hail bends the fins on outdoor coils
167 wind events: in ten years, and wind drives debris into outdoor units

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 charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. They also check the evaporator coil, inspect the condensate drain for clogs, and change or clean the filter. Electrical connections get tightened and the thermostat gets checked against what the system actually does when it runs. Coils caked with dirt or a drain line that backs up are two of the more common reasons a system loses cooling or shuts off on its own.
How often does an air conditioner need maintenance?: Once a year, ideally before the weather turns warm. Homes here only need cooling from June through August, so getting the check done before then gives a contractor time to order any part before the system has to work. Summer afternoons here average 82°F, and a unit that's low on refrigerant or has a dirty coil will struggle more once temperatures climb that high.
Is AC maintenance worth it?: Yes, because most of what causes a system to fail in the middle of summer is something a technician can catch ahead of time. A dirty coil, a weak capacitor, or a clogged drain line all show up during a routine check, before they cause the system to stop cooling or shut down completely. This area has also seen 167 damaging wind events and 16 hail events over the past ten years, including hail up to 1.75 inches, and a yearly check is when a contractor will spot outdoor unit damage from that kind of weather before it gets worse.
