Jackson County runs its heating and cooling hard, most of the year
Furnaces here work October through April. On nights that average 23°F, the burner cycles on and off most of the night to keep up, and most homes heat with gas. That burner and its igniter take the wear. A worn igniter shows up fast on a cold night. The furnace tries to start, clicks, and does not light.
Summer runs the other direction. Afternoons averaging 86°F keep the air conditioner running long hours for five straight months, and that steady load wears down a compressor or a capacitor over time. Jackson County also sees frequent high wind and regular winter storms, and close to one in five Missouri households lost power for a full day or more in 2024. A system that does not restart on its own after an outage, or a home with no heat while the power is out, is a common way people first notice something has failed.

A new furnace and air conditioner would cut about $210 a year off heating and cooling for a typical Jackson County home.
Estimates for a typical Jackson County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Missouri fuel prices and NOAA climate normals. Your home will differ.
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?
- Most often the thermostat, the igniter, or the power to the furnace is the problem. Check that the thermostat is set to heat and the temperature is above room temperature, and check that the furnace switch and breaker are on. If the furnace runs but no warm air comes out, or it shuts off after a few minutes, a contractor needs to look at the igniter or flame sensor. With winter nights here averaging 23°F, a furnace that will not stay lit needs attention the same day.
- Why is my system running but not cooling the house?
- If the blower is running but the air is not cold, check the outdoor unit first. If the fan outside is not spinning or the whole unit is silent, it is not getting power or it has shut down on a safety switch. If the outdoor unit is running but the air still is not cold, the filter may be blocked, or the coil may be frozen over, both of which stop the airflow that carries heat out of the house. A dirty filter is worth checking yourself. A frozen coil or a unit that will not start outside needs a contractor.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Confirm it is set to the right mode and the temperature is actually calling for heat or cooling, and swap the batteries if the screen is blank or dim. Next check the filter, and replace it if it is visibly gray or clogged, since a blocked filter can cut off airflow to the whole system. Then check the power, the breaker for the unit and, for a furnace, the switch that looks like a light switch near it. If all of that checks out and the system still is not heating or cooling, the problem is inside the equipment and a contractor will need to diagnose it.
