Five months of Hendersonville summer, and the storms in between
Your air conditioner works from May through September here, with afternoons that average 87°F. That is five straight months of the compressor running long hours to keep up. The condenser fan and the compressor itself take the wear, cycling on and on through the heat, and a unit that runs this hard every summer has less margin left when a part starts to go.
Sumner County has also logged 151 damaging wind events and 44 hail events over the past ten years, with hail up to 2 inches recorded. Wind can bend or tear the thin fins on the outdoor coil, and hail dents the cabinet or damages the fan blade. When that happens, you will notice the air is not as cold as it should be, or the outdoor unit is making a noise it did not make before.

A new air conditioner would cut about $40 a year off cooling for a typical Sumner 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?
- The most common reason is a dirty air filter choking off airflow over the coil. When that happens the coil can ice up, and once it's frozen the air coming through the vents turns warm. A refrigerant leak causes the same thing, but that's a repair only a contractor can find and fix. With summer afternoons here averaging 87°F, a system running low on airflow or refrigerant falls behind fast, so it's worth checking the filter first before calling anyone.
- Why is my AC leaking water?
- Water around your indoor unit almost always means the condensate drain line is clogged. That line carries away the water your AC pulls out of the air as it cools your home, and algae or debris can block it over time. When it backs up, it overflows the drain pan instead of draining outside. A frozen coil that's thawing can also leave water behind, so if the system was blowing warm air first, that's likely the cause instead.
- Why won't my AC turn on?
- Start with your thermostat's batteries and its setting, since a dead battery or a mode set to heat instead of cool will stop the system before it even tries to run. If the thermostat looks fine, check your breaker panel. With 151 damaging wind events recorded here over the past ten years, tripped breakers and power blips that stop a system from restarting on its own are common. If the breaker's fine and the thermostat calls for cooling but nothing happens outside, that points to something a contractor needs to diagnose.
