Common Furnace Problems I Fix in Garfield County

Oklahoma cold fronts can drop temperatures 40 degrees in a matter of hours. When your furnace fails, here’s what I typically find:

  • No heat at allIgniter failure, gas valve issue, or tripped safety switch
  • Short cyclingFurnace starts and shuts off quickly; usually a dirty filter, flame sensor, or heat exchanger issue
  • Weak airflowClogged filter, failing blower motor, or ductwork restriction
  • Unusual noisesBanging on startup (delayed ignition), squealing (belt or bearing), rattling (loose panels or ductwork)
  • Furnace runs constantlyThermostat calibration, heat exchanger crack, or undersized system
  • High energy billsDirty heat exchanger, failing capacitor, or inefficient operation
  • Yellow or flickering pilot lightPossible carbon monoxide risk; call immediately

My Diagnostic Process

I don’t guess. Every service call starts with a complete system diagnostic:

  1. Inspect heat exchanger for cracks, a safety-critical check on every call
  2. Test igniter, flame sensor, and gas valve operation
  3. Check static pressure and airflow through the system
  4. Inspect electrical components, capacitors, contactors, control board
  5. Verify thermostat calibration and operation
  6. Present findings and pricing before any repair begins

Furnace Repair vs. Replacement

I’ll always tell you the truth about whether repair or replacement makes more sense:

  • RepairFurnace is under 15 years old, repair cost is less than 50% of replacement cost, no heat exchanger cracks
  • ReplaceFurnace is 18+ years old, cracked heat exchanger (a safety issue), or recurring expensive repairs

If replacement makes sense, I’ll provide a full estimate on HVAC system replacement including high-efficiency options that can lower your monthly heating bills.
