Five months of Tennessee heat wears on your system
Your air conditioner runs from May through September here, and on afternoons that hit 88°F it works its hardest hours at a stretch. That kind of run time adds up on the compressor and the fan motor, the parts that carry the load all summer. When one of them starts to give out, you notice the air isn't as cold as it was, or the unit runs longer to get the house where you want it.
Murfreesboro also sees its share of hard weather. Rutherford County has logged 35 hail events and 137 damaging wind events over the past ten years. Hail up to 2 inches can dent or crack the outdoor unit's coil and fins, and high wind can knock the unit out of level or drive debris into it. Either one can cause trouble that shows up the next time you need the system to run.

A new air conditioner would cut about $40 a year off cooling for a typical Rutherford 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 the filter is clogged enough to choke off airflow across the coil, and warm house air just recirculates without picking up any cooling. A dirty outdoor unit does the same thing from the other side, or the system is simply low on refrigerant from a slow leak. With summer afternoons here running near 88°F, an AC that's struggling to keep up shows the problem fast. A contractor can check airflow, the coil, and refrigerant charge to find which one it is.
- Why is my AC leaking water?
- The drain line that carries condensation away from the indoor coil is clogged, or the coil itself is frozen and now thawing. Algae and dust build up inside that line over a cooling season and eventually block it, so the water backs up and spills out instead of draining outside. A frozen coil usually points to restricted airflow or low refrigerant. Either way, a contractor needs to clear the line or find why the coil froze.
- Why won't my AC turn on?
- Check the thermostat first. Dead batteries or a setting bumped to off or to heat will stop the system cold. If the thermostat looks right, a tripped breaker or a blown fuse at the outdoor unit is the next likely cause. If the breaker won't stay reset, leave it alone and have a contractor look at it.
