Four months of real heat, hard on your AC
Kingsport summers ask a lot of your air conditioner. From June through September, with afternoons averaging 85°F, the compressor runs long hours to keep up. That kind of steady load wears on the capacitor and the contactor, the parts that keep the compressor starting and running right.
Sullivan County has also seen its share of hail and wind, 12 hail events and 58 damaging wind events over the past ten years. The outdoor unit sits outside through all of it, and a bent fin or a hit fan blade can throw off the airflow it needs. When that happens, the house takes longer to cool, or the air coming out never quite gets cold.

A new air conditioner would save little on running costs in Sullivan County, so the repair decision comes down to the unit's condition.
Estimates for a typical Sullivan County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Tennessee 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 a refrigerant leak that leaves the system without enough refrigerant to cool the air. A frozen evaporator coil will also blow warm air, and it usually freezes because airflow was already restricted. Check the filter first. If it is clean and you still get warm air, the system needs a contractor to check refrigerant levels and look for a leak.
- Why is my AC leaking water?
- Most of the time this is a clogged condensate drain line. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through the drain line to the outside. Algae or debris can block that line, and the water backs up and drips inside instead. A frozen evaporator coil that then thaws can also flood the drain pan faster than it can drain.
- Why won't my AC turn on?
- Start with the thermostat batteries and the breaker for the outdoor unit, since both are common culprits and easy to check. If those are fine, a tripped safety switch or a failed capacitor could be keeping the compressor from starting. Kingsport gets its share of summer storms, and a power surge from lightning can trip a breaker or damage a capacitor, so check the breaker panel after any storm before calling for repair.
