Raymore runs its system almost year round
Your furnace and your air conditioner both work hard here. Heat runs October through April, seven months. Cooling picks up right after, May through September. That leaves almost no season where the system just sits idle.
Winter nights averaging 24°F mean the burner cycles on and off often to hold the house steady, and every cycle puts wear on the igniter and the parts that control the flame. Summer afternoons near 87°F push the compressor to run long stretches to keep up, and that kind of load is what wears out a capacitor or a contactor before its time. Cass County has also seen 89 damaging wind events over the past ten years, the kind of wind that can loosen an outdoor unit's wiring or knock its connections apart.

A new furnace and air conditioner would cut about $210 a year off heating and cooling for a typical Cass 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 the furnace off for service and gets left off by accident. Gas furnaces will not light if the pilot is out or the igniter has failed, and a contractor will need to look at that. Winter nights here drop to an average of 24°F, so a furnace that is not heating needs attention quickly.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the indoor coil, and when airflow drops too low the coil can ice over and stop cooling the air even though the system keeps running. Check that the outdoor unit is not blocked by grass, leaves, or anything piled against it, since it needs open airflow to release the heat pulled from inside the house. If the filter is clean and the outdoor unit is clear, the system may be low on refrigerant or have an electrical problem, and that needs a contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it, and the breaker for the indoor and outdoor units. Check the air filter and replace it if it is dark or clogged, since restricted airflow causes problems in both summer and winter. Look at the outdoor unit and clear away anything blocking it. If the system still is not working after that, a contractor will need to look at it, and having already checked these will save time on the visit.
