Five months of Maryville heat wears an AC down fast
From May through September your air conditioner is working most days, with afternoons averaging 86°F. That kind of stretch means long run times, and long run times are hard on a compressor and the capacitor that helps start it. A weak capacitor shows up as a unit that hums but won't start, or a fan that spins slow.
Blount County also sees its share of rough weather. Ten years of records show 107 damaging wind events and 16 hail storms, one with a hailstone a full inch across. Wind can rack the cabinet or knock a unit out of level, and hail dents the fins on the outdoor coil. Bent fins block airflow across the coil, and a system that can't move enough air across it will run long and cool poorly.

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

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 is low refrigerant from a leak, or a dirty filter choking off airflow over the coil. A filter that's clogged forces the coil to work with less air moving across it, and it can ice up as a result. With summer highs around 86°F here, an ice-covered coil will run for hours and still send warm air through the vents. Check the filter first. If it's clean and the air is still warm, the system needs a contractor to check refrigerant levels and look for a leak.
- Why is my AC leaking water?
- The condensate drain line is probably clogged. Your AC pulls moisture out of the air and that water is supposed to run out through this line, but algae and dust build up inside it over time and block the flow. When it backs up, water shows up at the indoor unit instead. A frozen coil that thaws out fast can cause the same thing, so if the airflow has been weak lately, that's worth mentioning to whoever comes to look at it.
- Why won't my AC turn on?
- Start with the thermostat batteries and the breaker before assuming the worst. A tripped breaker or a dead thermostat display will stop the whole system cold, and both are easy to check yourself. If the breaker keeps tripping when you reset it, that points to an electrical problem in the unit itself and it's time to call a contractor rather than keep resetting it. With 107 damaging wind events recorded here over the last ten years, it's also worth checking that nothing outside hit the outdoor unit or knocked loose a connection.
