Twelve months of work, with nothing that counts as a break
Your system doesn't get a season off in Wilson County. Heat runs October through April, then cooling takes over for May through September. That's every month of the year with the furnace or the AC doing something.
Winter nights average 31°F, cold enough that the burner cycles on and off for hours at a stretch, and each start puts wear on the igniter. Summer afternoons average 88°F, which means the compressor runs long stretches trying to keep up. Most homes here heat with electricity, so when the power goes out, the heat goes with it. Wilson County has seen 11 winter storms and 260 damaging wind events over the past ten years, and statewide, one in five households lost power for at least a day in 2024. If your system won't start back up after an outage, that's often what happened.

- Why is my heat not working?
- Start with the thermostat and the breaker before you assume the worst. Check that the thermostat is set to heat and a few degrees above room temperature, and check the breaker panel for a tripped switch. If it's a heat pump, the outdoor unit can ice over in weather near freezing, and that's normal to a point, but it should still be blowing warm air inside. If none of that brings the heat back, with winter nights here averaging 31°F, this isn't one to sit on.
- Why is my system running but not cooling the house?
- The system running without cooling usually means air isn't moving right or the refrigerant side has a problem, and only a contractor can tell you which. Check the filter first. A clogged filter chokes airflow across the coil, and a coil that can't get enough air will eventually ice over and blow warm air even though the blower is running. Also check that vents and returns inside aren't blocked by furniture or curtains. If the filter is clean and the vents are clear, the issue is likely inside the unit itself, low refrigerant or a failing part, and a contractor will need to diagnose it. With afternoons here reaching 88°F in summer, it's worth getting looked at soon rather than waiting it out.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it uses them, and the breaker panel first. These cause more no-heat and no-cool calls than actual equipment failure. Next, check the air filter. A dirty filter restricts airflow and can cause a furnace or air conditioner to shut down or run poorly. If you have a gas furnace with a standing pilot, check that the pilot light is lit. For central air or a heat pump, look at the outdoor unit and clear away any leaves, grass clippings or debris blocking it. If you've checked these and the system still isn't working right, it's time to have a contractor take a look.
