Furnace Repair

A furnace that will not light, cycles for ninety seconds and quits, or blows air that never gets warm is usually one of a short list of parts. Ignition and flame-sensing faults lead it, followed by pressure switch and condensate problems, a thermostat at $150 to $450, and a blower motor at $350 to $900. Diagnosis is $95, and that charge comes off the invoice when you approve the repair while we are still at the house. One local detail changes the work. Rural properties across McClain, Grady, and Garvin counties are commonly on propane rather than city gas, and propane needs different burner orifices and different manifold pressures. A furnace converted carelessly, or one running on a regulator that has drifted, shows up as sooting, short cycling, or a burner that will not hold flame. That gets checked before parts get replaced. Red-dirt dust is the other constant here, loading filters and blower wheels faster than most climates and pushing a struggling motor harder every season. If the diagnosis points to replacement rather than repair, the estimate for the new equipment is free: furnace replacement runs $4,000 to $7,500, and gas furnaces sold today must meet at least 80% AFUE. Labor on repairs is $125 per hour during business hours, $154.50 after hours.
