Pettis County runs its system almost year round
Your furnace works October through April here, and the air conditioner takes over May through September. That leaves the system idle only a few weeks a year, if that. Winter nights average 24°F, cold enough that the burner cycles on and off for hours through the night. Come summer, afternoons hit 86°F and the compressor runs long stretches to keep up.
That much runtime wears on parts in both directions. Igniters and flame sensors wear out from the winter cycling. Capacitors and contactors wear out from the summer heat and long compressor runs. 44.7% of homes here heat with electricity, so when the power goes out, heat stops with it. Pettis County has seen 8 winter storms and 47 damaging wind events over the past ten years, and either one can take down a power line or a tree limb on an outdoor unit.

- Why is my heat not working?
- Start with the thermostat. Check that it's set to heat and the temperature is set above room temperature, since a setting bumped by accident is the simplest explanation. If that's fine, check your breaker panel and any switch near the furnace that looks like a light switch, since that cuts power to the unit. A furnace that won't light at all often has a bad igniter or a flame sensor that needs cleaning, and with lows near 24°F overnight here, that's not something to leave for long.
- 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 coil can freeze up when that happens, which stops it from pulling heat out of the air. Also check that all your supply vents are open and unblocked by furniture or rugs. If the filter is clean and air is moving but it's still not cold, the system may be low on refrigerant, and that's a job for a contractor since it involves finding and sealing a leak.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first, since a dead thermostat can look like a dead system. Next, check your breaker panel for a tripped breaker and any nearby switch that might have been turned off. Look at the air filter and replace it if it's gray or clogged, since restricted airflow causes problems on both the heating and cooling side. If it's a gas furnace, check for a pilot light or ignition light on the unit itself. If none of that explains it, a contractor will still need to look at the actual parts, but you'll have ruled out the easy causes first.
