Five months of Lebanon summer wears on an AC fast
Your air conditioner works from May through September here, and on afternoons averaging 88°F, it runs long hours to keep up. That kind of steady demand wears on the compressor and the capacitor that starts it. A weak capacitor can't kick the compressor on, and the unit outside just hums or clicks without starting.
Wilson County has also seen 260 damaging wind events and 35 hail storms over the past ten years, with hail up to 3 inches. Wind drives debris into the outdoor unit and can bend the fins that let it release heat. Hail that size can dent the cabinet or damage the fan blade. When the outdoor unit can't shed heat the way it should, the house stops cooling even though the system is running.

A new air conditioner would cut about $50 a year off cooling for a typical Wilson County home.
Estimates for a typical Wilson 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?
- Most of the time this comes down to the refrigerant level, the airflow, or the outdoor unit. A dirty filter or blocked vent starves the system of airflow and the air coming out feels weak or warm. Low refrigerant means the system cannot pull heat out of the air, and that points to a leak somewhere in the lines. With summer afternoons here running near 88°F, the outdoor unit is also working hard, and if the coil outside is caked with dirt or debris it cannot release the heat it is pulling from your house. A contractor can check the refrigerant charge and the coils to find which one it is.
- Why is my AC leaking water?
- This usually means the condensate drain line is clogged, or the coil is frozen and now thawing. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through a drain line to the outside. Algae and dirt build up in that line over time and block it, so the water backs up and drips inside instead. A frozen coil is a different problem, often tied to low airflow or low refrigerant, and it will leak water once it melts. Either way, the water is a sign of something upstream that needs a look.
- Why won't my AC turn on?
- Start with the thermostat and the breaker before assuming the worst. If the thermostat screen is blank, check its batteries, and check the breaker box for a tripped switch since AC units draw a lot of power and can trip one. With 260 damaging wind events recorded here over the past ten years, a power blip or surge is a common reason a unit stops responding even when everything inside it is fine. If the breaker holds and the thermostat is working but the unit still won't start, the problem is likely electrical inside the unit itself, and that calls for a contractor to check it.
