Maury County asks for heat or cooling all year
Your system runs from October through April to keep the house warm, then flips over and runs May through September to keep it cool. There is almost no rest between the two. Winter nights average 30°F, cold enough that the furnace cycles on and off through the night, and summer afternoons hit 88°F, which keeps the air conditioner working hard from midday into evening.
Maury County has seen 104 damaging wind events and 9 winter storms over the past ten years, and in 2024, one in five Tennessee households lost power for at least 24 hours. Most of the year's heat here comes from electricity, so when the power drops, so does the heat. When it comes back on, the system has to start itself back up, and that is when a weak part is most likely to fail.

- Why is my heat not working?
- Check the thermostat first. Make sure it is set to heat and a few degrees above room temperature. Then check the breaker panel for a tripped breaker. If those are fine and you have gas heat, look for a pilot light or igniter that isn't lighting. Furnaces here run 7 months a year, from October through April, and a lot of problems show up on the first cold snap because that's the first real test the system has had in months.
- Why is my system running but not cooling the house?
- If air is moving but it isn't cold, check the filter first. A dirty filter blocks airflow, and that can freeze the evaporator coil. Low refrigerant can freeze it too. Once the coil is frozen, the system needs time off to thaw before it can cool again. If the filter is clean and the coil still freezes or the air stays warm, a contractor will need to check refrigerant levels and airflow through the ducts.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set correctly, has fresh batteries if it uses them, and is actually calling for heat or cooling. Next check the breaker panel. A lot of no-heat and no-cool calls trace back to power rather than the equipment itself. Check the air filter and replace it if it's dirty, since a clogged filter can cause weak airflow and a frozen coil. If you have a gas furnace, look for a pilot light or a reset switch on the unit itself. If all of that checks out and the system still isn't working, a contractor will need to look at it directly.
