Georgetown Furnace Repair — Every Problem, Properly Diagnosed
Georgetown furnaces sit idle from April through October — then get hit with a cold snap in November. That extended dormancy creates predictable failure patterns. Our technicians test systematically: ignitor first, then flame sensor, gas valve, pressure switch, and control board. This sequence prevents replacing an expensive control board when the actual problem is a $95 ignitor.
The most common Georgetown furnace call: system attempts to start, you hear the inducer run, but the burners don't ignite. The furnace tries 3 times, then locks out. Cause is almost always a failed hot surface ignitor (thermal fatigue from summer heat in the attic) or a dirty flame sensor that can't detect the flame. Both are on the truck. Both are under $200 to fix.
Furnace Repairs We Perform
Ignitor, flame sensor, gas valve, or pressure switch — we test each in sequence to find the actual failure.
If the blower runs but burners don't fire, it's an ignition or safety issue. We diagnose the specific point of failure.
Indicates overheating (high-limit trips) or a faulty flame sensor. Root cause matters — repeated short cycling cracks heat exchangers.
Banging on startup often means delayed ignition — gas accumulating before lighting. This is a safety issue requiring immediate diagnosis.
Usually a blocked pressure port, faulty pressure switch, or failed inducer — we verify the specific failure point.
Motor drawing excess current or a wiring fault — don't reset repeatedly. We diagnose the electrical root cause.
Rollout means flames extended outside the heat exchanger. This is serious — we find out why before resetting.
Usually restricted airflow — dirty filter, blocked vents, or closed registers. But we also check the heat exchanger for cracks.
