A system that runs all year, in both directions
Rutherford County needs heat October through April and cooling May through September. That covers the whole year, with almost no stretch where the system just sits idle. On winter nights that average 31°F, the furnace or heat pump cycles on and off through the night to hold the temperature. On summer afternoons averaging 88°F, the compressor runs the same way, coming on often and staying on longer to keep up.
Most homes here heat with electricity, so a power outage takes down heating and cooling both. The county has logged 137 damaging wind events and 9 winter storms over the past ten years, and across Tennessee one in five households lost power for at least a day in 2024. Most systems come back on by themselves once power returns. Whether they run right after that depends on how much wear the year already put on them.

- Why is my heat not working?
- Start with the thermostat and the breaker panel, since both cause more no-heat calls than the furnace itself. If the thermostat screen is blank, check the breaker or the furnace switch, which looks like a light switch near the unit. A pilot light that will not stay lit, or a furnace that starts and shuts off again, points to the igniter or the flame sensor. Once you have ruled out the simple causes, a contractor can test the parts that need tools to check.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and the system will run without bringing the house down to temperature. Next look at the outdoor unit and clear away any leaves, grass clippings, or anything blocking the sides. If the filter is clean and the outdoor unit has airflow, the system may be low on refrigerant or the coil may be freezing up, and that needs a contractor to check.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings, the breaker for the furnace or air conditioner, and the air filter. A dead thermostat display usually means batteries or a tripped breaker, not a broken system. A filter you can see dust through should be replaced, since a clogged one restricts airflow to the furnace or the coil. If the outdoor unit is not running at all, check that nothing is blocking the disconnect box beside it. After Murfreesboro's wind storms, it is also worth checking that the outdoor unit itself was not knocked or shifted.
