What I find

Common furnace problems in Oklahoma City

OKC winters swing from mild to severe in a few hours. When the furnace quits, this is usually what I find.

  • No heat at allUsually an ignitor, gas valve or tripped limit switch. Often fixed on the same trip.
  • Blower runs, no warm airThe burner is not lighting. Ignitor, flame sensor or gas supply.
  • Lights, then shuts offA dirty flame sensor, a clogged filter or the furnace overheating.
  • Banging on startupDelayed ignition. Gas builds before it lights, a safety problem to fix promptly.
  • Weak or uneven airflowClogged filter, failing blower motor or ductwork trouble.
  • Runs constantlyThermostat, a cracked heat exchanger, or a system too small for the house.
  • Burning smell from the ventsDust burn-off on the first cold day, or a failing part. Do not ignore it.
  • Gas bill climbingDirty heat exchanger, failing inducer, or a furnace running more than it should.

The diagnostic

What I check before I quote

  1. Heat exchanger firstI look for cracks on every call. A cracked heat exchanger is a carbon monoxide risk.
  2. Ignition sequenceIgnitor, flame sensor and gas valve, verified in the order the furnace runs them.
  3. AirflowStatic pressure and the filter. Most overheating trips start here.
  4. Electrical and controlsCapacitor, inducer, limit switches, control board codes.
  5. ThermostatCalibration and wiring, so the call for heat actually reaches the furnace.
  6. Written price, then you decideI explain what I found and what it costs before touching anything.

Repair or replace

A straight answer on your furnace

Repair usually makes sense when the furnace is under 15 years old, the repair is under half the cost of a new one, and the heat exchanger is sound. Past 18 years, a cracked heat exchanger, or a string of repairs, and replacement usually wins.

Straight answers

How much does furnace repair cost in OKC?

The service call is $210 flat: $99 dispatch plus $111 diagnostic. Common repairs run from $100 for a flame sensor to $950 for a control board, and I quote the repair in writing before I start. The diagnostic is not credited toward the repair.

Do you do emergency furnace repair in Oklahoma City?

Yes. No-heat calls go first when it is cold. I am based in Kingfisher, about 45 minutes from the metro, so call and I will give you an honest arrival time. After hours is $309.

Can you fix my furnace the same day?

Most common failures, ignitors, flame sensors, capacitors and blower motors, get fixed on the first visit because the truck carries them. If a part has to be ordered, I tell you the timeline up front.

Why does my furnace blow cold air in the middle of a cycle?

Usually a dirty flame sensor, or a high limit switch tripping on restricted airflow. The blower keeps running while the burners shut off. I see it every Oklahoma City cold snap, and the diagnostic pins down which one it is.

Are you licensed to work in Oklahoma City?

Yes. I hold an Oklahoma Master HVAC License, I am NATE certified, and I am fully licensed and insured.

Do you smell gas?

Leave the house now, do not flip switches or use the phone inside, and call your gas utility or 911 from outside. Once the utility says it is safe, call 405-375-4822 and I will find the cause.
