Four months of real heat, every year

Your air conditioner works hard from June through September, with summer afternoons here averaging 83°F. That kind of steady demand keeps the compressor running long hours day after day, and it's the part that tends to give out first. When it does, the unit may run without cooling, or it may stop coming on at all.

Kings County also sees its share of rough weather, with 56 damaging wind events recorded over the past ten years. Wind that strong can knock a condenser out of alignment or drive debris into the coil outside, and either one shows up as weak airflow or a system that struggles to keep the house cool.

A new air conditioner would cut about $40 a year off cooling for a typical Kings County home.

  • A new one at the federal minimum, 13.4 SEER2$410 a year
  • An older air conditioner$450 a year

Estimates for a typical Kings County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, New York fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Why is my AC not blowing cold air?
The most common cause is a dirty air filter choking off airflow, or the outdoor unit's coil covered in dirt and unable to release heat. Low refrigerant from a leak also causes this, and that shows up as warm air along with ice forming on the indoor coil or lines. Check the filter first since that's the one thing you can fix yourself. If the filter is clean and you still get warm air, a contractor needs to check the refrigerant charge and the coils.
Why is my AC leaking water?
Most of the time this means the condensate drain line is clogged. Your AC pulls moisture out of the air as it cools your home, and that water is supposed to run out through a drain line to the outside. When the line clogs with algae or debris, the water backs up and drips inside instead, often near the indoor unit. A frozen coil that's now thawing can cause the same thing, so if you saw ice on the unit earlier, that's likely the cause.
Why won't my AC turn on?
Start with the thermostat and the breaker panel. A dead thermostat battery or a tripped breaker will stop the whole system with no other symptoms. If the breaker keeps tripping when you reset it, stop resetting it and have a contractor look at it, since that usually points to an electrical problem in the unit itself. Storms in this area bring damaging wind often enough that a tripped breaker after bad weather is worth checking first.
