Three months of heat, hard on your AC

Lindenhurst only asks for cooling from June through August, but those three months work the system hard. Summer afternoons average 80°F, and a unit that sits idle most of the year has to start up strong and run for hours at a stretch once the heat sets in.

That pattern of long summer storage followed by heavy demand is hard on capacitors and contactors, the parts that get the compressor going. Wind is the other factor here. Suffolk County has logged 434 damaging wind events over the past ten years, enough to knock an outdoor unit's cabinet out of alignment or send debris into the fan and coil. If your AC is struggling to start, cycling more than it used to, or blowing air that is not as cold as it should be, this is often why.

A new air conditioner would save little on running costs in Suffolk County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$270 a year
  • An older air conditioner$290 a year

Estimates for a typical Suffolk 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 across the coil. Low refrigerant from a leak will also do it, and so will a coil that has frozen over from restricted airflow. If the air coming out is warm or barely moving, check the filter first, since that is the one thing you can rule out yourself before a contractor looks at the rest.
Why is my AC leaking water?
Warm, humid air passes over a cold coil inside your air handler, and the moisture that condenses off it is supposed to drain outside through a small drain line. When that line clogs with algae or dirt, the water backs up and drips inside instead. A frozen coil that then thaws can also flood the drain pan faster than it can drain. Either way the fix is clearing or repairing the drain, not the AC itself.
Why won't my AC turn on?
Start with the thermostat, since dead batteries or a setting knocked out of place are common and easy to check yourself. If the thermostat looks fine, a tripped breaker or a blown fuse at the outdoor unit is the next likely cause. Lindenhurst sees its share of damaging wind, and a power blip during a storm can trip a breaker without any other damage, so check the electrical panel before assuming the worst.
