Common Furnace Problems We Fix in Major County

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

• No heat at all — Igniter failure, gas valve issue, or tripped safety switch
• Short cycling — Furnace starts and shuts off quickly; usually a dirty filter, flame sensor, or heat exchanger issue
• Weak airflow — Clogged filter, failing blower motor, or ductwork restriction
• Unusual noises — Banging on startup (delayed ignition), squealing (belt or bearing), rattling (loose panels)
• Furnace runs constantly — Thermostat calibration, heat exchanger crack, or undersized system
• High energy bills — Dirty heat exchanger, failing capacitor, or inefficient operation
• Yellow or flickering pilot light — Possible carbon monoxide risk; call immediately

Our Diagnostic Process

We 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

Furnace Repair vs. Replacement

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

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

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