Warrensburg asks a lot of your system, both directions
Your furnace runs October through April here, seven months of the year, and on nights that average 24°F it cycles on and off again and again to keep up. Each start puts wear on the igniter and the ignition sensor, the parts that light the burner and prove it caught. When one of them gives out, the furnace won't fire and the house goes cold.
Then summer flips the load onto the air conditioner for five months straight, with afternoons averaging 87°F. The compressor runs long hours in that heat, and capacitors and contactors wear out faster under that kind of strain. Almost half the homes here heat with electricity, so when a breaker trips or a storm knocks out power, heat stops along with everything else. Johnson County has seen 61 damaging wind events and 10 winter storms over the past ten years, and statewide, close to one in five households lost power for a full day or more in 2024. A system already worn down by the swings between 24°F nights and 87°F afternoons has less room to absorb that kind of hit.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace before you assume the worst. Check that the thermostat is set to heat and a few degrees above room temperature, and check the breaker or switch at the furnace itself. If those are fine, the igniter or the flame sensor is often the next place a contractor looks, since either one failing will stop the furnace from firing even though the blower still runs. With winter nights here averaging 24°F, a furnace that will not fire is not something to leave for later.
- Why is my system running but not cooling the house?
- A system that runs but does not cool is usually blocked or low, not broken outright. Check the air filter first, since a clogged one chokes off airflow and can freeze the coil. If the filter is clean and the vents are open, the problem is more likely low refrigerant or a coil that is already frozen over, and both need a contractor to look at it. On the hottest afternoons here, 87°F on average in summer, a house can warm up fast once cooling capacity drops.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it, and the breaker for the system before anything else. Look at the air filter and replace it if it is gray or clogged, since restricted airflow causes problems on both the heating and cooling side. Outside, make sure the condenser unit is not blocked by leaves, mulch, or anything else sitting against it. If the system still is not working after that, a contractor will need to diagnose it directly rather than guess over the phone.
