Common Furnace Problems I Fix in Major 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)
• 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

→ Need same-day service? See my Emergency Furnace Repair page.

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
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

Diagnostic is $111 diagnostic, part of the $210 flat repair-call price. Accept the estimate within 10 days and I give the $99 dispatch back. Dispatch is $99.

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
