Frequently Asked Questions About Gas Furnace Repair & Diagnostics

Cold air is typically caused by a dirty flame sensor that shuts down the gas valve for safety, a malfunctioning hot surface igniter, a tripped high-limit switch, or an extinguished pilot assembly.
Warning signs include yellow lazy burner flames instead of crisp blue, soot buildup inside the furnace cabinet, unexplained headaches or nausea, and carbon monoxide detector alerts.
Yes, our mobile service vehicles carry OEM and universal gas valves, thermocouple sensors, electronic control boards, draft inducer motors, and pressure switches for Carrier, Trane, Lennox, Rheem, Goodman, and York.
A loud booming noise upon startup indicates delayed ignition. Dirt, lint, or corrosion partially clogs burner ports, causing gas to pool in the combustion chamber before igniting violently. Our technicians clean the burners and adjust ignition electrodes to prevent heat exchanger damage.
Gas furnace burners and flame sensor rods should be cleaned annually. Carbon and oxidation buildup on the flame rod causes micro-amperage loss, prompting the control board to shut off the gas valve within 3 to 5 seconds.
We repair all major residential gas furnace manufacturers, including Carrier, Trane, Lennox, Rheem, Goodman, York, Bryant, Ruud, Amana, Heil, and American Standard, for both 80% AFUE standard and 96%+ high-efficiency condensing units.
