Four months of hard running, plus what the storms leave behind

Your air conditioner earns its keep from June through September here, working against afternoons that average 87°F. That kind of heat means long run times day after day, and the parts that push through those hours are the ones that fail first. A capacitor weakens and the compressor struggles to start. A condenser fan motor wears out from running most of the day for months straight. You notice it as a system that runs but doesn't cool like it did, or one that hums and clicks but never quite starts.

Greene County has also seen 140 hail events and 302 damaging wind events over the past ten years, with hail up to 3 inches across. The condenser sits outside for all of it, and hail bends the thin fins on the coil, cutting down the airflow it needs. Wind-blown debris does the same, or knocks the unit hard enough to throw off the refrigerant lines. After a storm, a system that ran fine the day before can start blowing warm air or tripping off on its own.

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

  • A new one at the federal minimum, 13.4 SEER2$260 a year
  • An older air conditioner$280 a year

Estimates for a typical Greene 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 the filter is clogged and starving the system of airflow, or the refrigerant is low from a leak somewhere in the line. A dirty outdoor unit can cause the same thing, since it needs open airflow around the coil to move heat outside. Check the filter first since that's the one thing you can rule out yourself. If it's clean and you're still getting warm air, a contractor needs to check the refrigerant charge and the coil.
Why is my AC leaking water?
The condensate drain line is probably clogged, and water is backing up instead of draining outside like it should. This is common with algae or dirt building up inside the line over time. It can also mean the evaporator coil has frozen and is now thawing and dripping. Either way the system usually needs to be shut off until a contractor clears the line or finds what's freezing the coil.
Why won't my AC turn on?
Check the thermostat first, since dead batteries or a setting knocked off cool will stop the system before it even tries to start. If the thermostat looks right, check the breaker, since AC units trip breakers more than people expect. Springfield's storms have brought 140 hail events and 302 damaging wind events over the past ten years, and either one can knock out power to the outdoor unit or damage it directly. If the breaker keeps tripping when you reset it, stop trying and have a contractor look at it.
