Your system runs almost all year here
Liberty needs heat from October through April and cooling from May through September. That is most of the year with the furnace or the air conditioner working, and only a few weeks where neither has to run. On winter nights averaging 22°F, the burner cycles on and off for hours to hold the house steady, and every start puts wear on the igniter. On summer afternoons near 86°F, the air conditioner runs long stretches to keep up, and that load falls on the compressor and the capacitor that starts it.
Clay County also sees real storms. Nine winter storms and 116 damaging wind events have hit the area over the past ten years, and statewide, close to one in five Missouri households lost power for a full day or more in 2024. A furnace or air conditioner that loses power and comes back on can trip a breaker or fail to restart on its own, so a system that worked fine before a storm is worth checking after one.

A new furnace and air conditioner would cut about $220 a year off heating and cooling for a typical Clay County home.

Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is set above room temperature, and check the batteries if it uses them. If the thermostat looks right, check the breaker for the furnace and the switch that looks like a light switch near the unit, since that shuts it off too. Gas furnaces will not run if the pilot is out or the igniter has failed, and that is a job for a contractor. With winter nights here averaging 22°F, a furnace that will not start needs attention the same day.
- 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 when that happens the coil can ice up and stop cooling the air even though the system keeps running. Check that all the supply vents in the house are open and not blocked by furniture or rugs. If the filter is clean and the vents are open, the refrigerant charge or the outdoor unit may be the problem, and that calls for a contractor to check with gauges.
- What can I check before calling for HVAC repair?
- Check the thermostat settings first, since a wrong mode or a dead battery looks exactly like a bigger problem. Check the breaker panel and any shutoff switch near the indoor and outdoor units. Look at the air filter and replace it if it is dark or clogged, since restricted airflow causes both heating and cooling complaints. For the outdoor unit, clear away leaves, grass clippings or anything piled against it. If the system still is not working after that, a contractor will need to diagnose it directly.
