Five months of heat, and storms that hit the unit outside

Your air conditioner runs May through September here, with summer afternoons averaging 88°F. That is five straight months of the compressor cycling on and off through the hottest part of the day, and long runs like that wear on the capacitor and the fan motor before they wear on anything else. When one of those goes, the outdoor unit hums but the fan does not turn, or it does not start at all.

Jasper County has also logged 82 hail events and 124 damaging wind events over the past ten years, with hail up to 3 inches. That kind of storm bends the thin fins on the outdoor coil and can crack the fan blade, so if your air conditioner has run rough or blown warm air right after a bad storm, the outdoor unit is the place to check first.

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

  • A new one at the federal minimum, 13.4 SEER2$310 a year
  • An older air conditioner$330 a year

Estimates for a typical Jasper County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Missouri 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?
Most of the time this means the system is low on refrigerant or the coil has iced over. A dirty air filter can also choke off airflow enough that the air coming out feels warm. Check the filter first since that is the easy part. If it is clean and you still get warm air, the refrigerant charge or the compressor likely needs a contractor to look at it, especially after a summer of running hard against 88°F afternoons.
Why is my AC leaking water?
This usually means the condensate drain line is clogged, or the coil has frozen and is now thawing and dripping. Algae and dust build up in that drain line over a cooling season and eventually block it, so water backs up and spills out instead of draining away. If the line is clear and it is still leaking, the coil itself may need attention, and that is a job for a contractor.
Why won't my AC turn on?
Start with the thermostat batteries and the breaker before assuming the worst. A tripped breaker or a thermostat that lost power will stop the system cold and both are easy to check yourself. If those are fine, the capacitor or the contactor may have failed, and after 124 damaging wind events here in the past ten years, a power surge is a real possibility worth having a contractor check.
