Four months of real heat, hard on the parts that keep up
Crossville doesn't ask much of an air conditioner most of the year, but June through September change that. With afternoons averaging 83°F, the compressor runs long hours to hold the house steady, and it doesn't get much of a break between cycles. That steady load is what wears down a capacitor or a contactor before its time.
Cumberland County has also seen its share of rough weather, with 54 damaging wind events and 12 hail storms over the past ten years, one dropping hail over two inches wide. A unit sitting outside through that can end up with a bent fan blade, a dented cabinet, or coil fins packed with debris. Sometimes the damage shows up right away as a system that won't start. Other times it shows up weeks later, when the airflow across the coil is choked down and the house just doesn't cool the way it used to.

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

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 across the coil. When that happens the coil can ice up and stop cooling the air at all. A low refrigerant charge or a failing compressor will also leave you with air that moves but never gets cold. Check the filter first, and if it's clean the problem is inside the system and needs a contractor to look at it.
- Why is my AC leaking water?
- Most of the time this means the condensate drain line is clogged. Your AC pulls moisture out of the air and that water is supposed to run out through the drain line, but algae and dirt build up inside it over time and back the water up until it overflows. A dirty filter can cause the same problem by icing the coil, which then drips as it thaws. Either way it needs clearing out before it damages the floor or the unit itself.
- Why won't my AC turn on?
- Start with the thermostat. Check that it's set to cool and the temperature is actually below the room temperature, and if it runs on batteries, try fresh ones. If the thermostat looks fine, check your breaker panel, since a tripped breaker will shut the whole system down. Summer storms here bring damaging wind often enough that a breaker trip or a power blip is a real possibility, so that's worth ruling out before assuming something inside the unit has failed.
