Furnace quit? Heat back on, done right.
A January cold snap finds the weak part: an igniter, a dirty flame sensor, a stuck pressure switch, a heat pump that will not defrost. I check the safety side first, find the real fault, and put the price in writing before I fix it.

The failures I see every Oklahoma winter
- Won’t turn on at allUsually the igniter, a tripped limit or a control board. Why a furnace won’t start
- Lights, then shuts right offThe classic dirty or failing flame sensor.
- Runs, but the house stays coldGas pressure, airflow, or a safety cutting the burners. Common causes
- Heat pump blowing cold airA stuck reversing valve, a refrigerant leak, or stuck in cool mode.
- Outdoor unit iced overNormal in freezing rain, but a bad defrost board or sensor means it will not clear itself.
- Backup heat running all the timeLow charge, an undersized heat pump, or aux heat taking over too early.
- Short cyclingOn and off every few minutes: pressure switch, limit, low charge or the thermostat.
- Strange noises or smellsA noisy inducer at startup is a warning sign. A burning smell that is strong or does not fade means get everyone out and call 911 from outside, then call me.
Safety first, then the fault
- Combustion safetyHeat exchanger for cracks, flue and venting for blockage or backdraft, and a carbon monoxide check. Nothing else happens until this passes.
- Gas and ignitionGas valve operation and pressure on a manometer, igniter, flame sensor, limit and rollout switches.
- ControlsControl board error codes and relays, inducer pre-purge and pressure switch, thermostat heat call.
- AirflowBlower amps and speed, filter and return restriction, temperature rise, static pressure.
- Written price, then you decideYou know the number before I touch a wrench.
How much does heating repair cost in Kingfisher, Oklahoma?
Real ranges from jobs I have run in Kingfisher County, parts and labor. Your exact price is confirmed on site, in writing, before work starts.

6-month labor guarantee on the part I replaced · Financing covers repairs too
What I would do if it were my house
Past 15 to 20 years, a cracked heat exchanger, or a repair that costs more than half of replacing: replacement usually wins. Otherwise I fix it. I do not make more money steering you to a new system.

Why a heat pump quits differently than a furnace
Heat pumps fail in their own ways, and Oklahoma winters stress them in predictable ones. Blowing cold air in heat mode usually means a failed reversing valve, a refrigerant leak, or a system stuck in cool mode. Ice on the outdoor unit is normal in freezing rain, but if a stuck defrost board or a failed defrost sensor keeps it from clearing itself, it will keep building. Backup heat running all the time points to low charge, a heat pump undersized for the house, or auxiliary heat taking over too early. And if the system runs with no heat coming out at all, I am looking at charge loss, the compressor, or a reversing valve stuck in the cooling position.
The reversing valve switches the heat pump between heating and cooling. When it sticks, you get cold air in winter or no cooling in summer. It is one of the trickier diagnoses, because I have to check both the solenoid coil and the valve body, and I do that before I recommend a $600 to $1,500 replacement.
Geothermal is its own animal. A geothermal unit shares the compressor, reversing valve and refrigerant circuit with an air-source heat pump, but the ground loop adds failure points of its own: loop pumps, antifreeze concentration, flow restrictions and pressure loss in the loop field. As an IGSHPA-accredited contractor I service both the unit and the loop. More on ice in heat pumps freezing up.
No-heat calls go first
A heating failure in a January ice storm is not a call you schedule for next week. In severe cold, no-heat calls go to the front of my line wherever the schedule allows, across Kingfisher, Watonga, Hennessey, Cashion and Crescent, and every town in my seven counties. If the furnace will not start at all, read why a furnace will not turn on; if it is a true emergency, see emergency furnace repair.
- The rest of my heating checklistBeyond combustion, gas and controls, I check duct leakage and obvious disconnects, static pressure for undersized or blocked ductwork, the capacitor on heat pump systems, and the condensate drain on high-efficiency furnaces, which freezes or clogs and shuts the furnace down.
- Blower motor giving out?An OEM PSC replacement runs $1,912 and a standard PSC blower motor $2,187. An Azure ECM variable-speed upgrade is $2,304 to $2,438 and runs quieter and lasts longer. See the side-by-side.

Straight answers
How much does heating repair cost in Kingfisher, Oklahoma?
The service call is $210 flat: $99 dispatch plus $111 diagnostic. The repair is priced in writing before I start, and most common furnace repairs run $125 to $900. The diagnostic is not credited toward the repair.
I smell gas. What do I do?
Do not troubleshoot it. Leave the house, then call the gas utility or 911 from outside. Once they have made it safe, call me at 405-375-4822.
My furnace blows cold air. What now?
Check the filter and the thermostat mode first. If those look fine, a safety control may be tripping. I run combustion and airflow checks to find the fault.
Is it safe to run the heater with a burning smell?
A light dusty smell for the first few minutes of the season is normal. If you see smoke, smell burning wiring, or the smell is strong or does not fade, get everyone out and call 911 from outside. If a carbon monoxide alarm sounds, get everyone outside into fresh air and call 911 from outside. Once it is safe, call me at 405-375-4822.
Can you check carbon monoxide levels?
Yes. I carry CO instruments and inspect the heat exchanger and venting to confirm the furnace is running safely.
What does it cost after hours?
$309: $198 dispatch plus $111 diagnostic, for furnaces, heat pumps and residential AC. It is not refundable and is not credited toward the repair. Geothermal is $348 flat, any hour.
Do you work on gas and electric furnaces?
Yes. I test ignition, flame signal, pressure switches, elements, sequencers and safeties to each model’s requirements.
Why is my heat pump blowing cold air in heat mode?
Usually a failed reversing valve, a refrigerant leak, or the system stuck in cool mode. I check the reversing valve’s solenoid coil and valve body before recommending a replacement.
Is ice on my heat pump normal?
A little frost in freezing rain is normal and the defrost cycle clears it. If ice keeps building, the defrost board or sensor has likely failed.
Do you repair geothermal heat pumps and ground loops?
Yes. I am IGSHPA accredited and service both the unit and the loop: loop pumps, antifreeze, flow and pressure. A geothermal diagnostic is $348 flat, any hour.
