Common Furnace Problems We Fix in Oklahoma City
Oklahoma City winters can swing from mild to severe within hours. When your furnace fails, here’s what we typically find:
- No heat at all — Usually an igniter, gas valve, or tripped limit switch — often a same-trip repair
- Blower runs but no warm air — Burner not lighting; check igniter, flame sensor, and gas supply
- Short cycling — Furnace starts then shuts off quickly; commonly a dirty filter, flame sensor, or overheating issue
- Weak or uneven airflow — Clogged filter, failing blower motor, or ductwork problems
- Banging or popping on startup — Delayed ignition — gas is building before it lights; a safety concern to address promptly
- Constant running — Thermostat issue, heat exchanger crack, or system undersized for the load
- Burning smell from vents — Could be dust burn-off at season start, or a failing component — don’t ignore it
- Spiking gas bills — Dirty heat exchanger, failing inducer, or system running more than it should

Our Diagnostic Process
Every furnace repair call starts with a complete diagnostic, not a parts swap:
- Heat exchanger inspection — We check for cracks on every call. A cracked heat exchanger is a carbon monoxide risk.
- Ignition system test — Igniter, flame sensor, and gas valve operation
- Airflow check — Static pressure measurement and filter inspection
- Electrical inspection — Capacitors, contactor, control board
- Thermostat verification — Calibration and wiring check
- Upfront pricing — We explain what we found and the cost before touching anything

Repair vs. Replacement
We’ll give you a straight answer on whether repair or replacement makes more financial sense. General guidelines:
- Repair makes sense when the furnace is under 15 years old, the repair cost is under 50% of replacement, and there’s no cracked heat exchanger
- Replacement makes sense when the furnace is 18+ years old, has a cracked heat exchanger, or has a history of recurring repairs
