Gas furnaces fail in recognizable patterns, and most of those patterns come down to ignition, airflow, or a safety device doing its job. This page focuses on gas furnace work specifically; if your home has a heat pump or electric heat, start with heating repair.
Faults we see most often
- Cracked or failed hot surface igniter, so the burners never light
- A dirty flame sensor causing the furnace to light and then shut down seconds later
- Pressure switch trips from a blocked flue, condensate line, or failing inducer motor
- High limit trips caused by restricted airflow from a clogged filter or closed vents
- Failed blower motor or capacitor
- Gas valve and control board failures
- Thermostat wiring faults that produce intermittent heat
Why the sequence matters
A modern furnace runs a strict startup sequence, and a fault at any step stops the whole thing. A technician reads the control board diagnostics, then verifies the step that failed with actual measurements rather than swapping parts until the symptom goes away.
Safety items we never skip
Flue and venting inspection, combustion air, and heat exchanger condition. If we find evidence of a compromised heat exchanger, we explain what we saw and what it means for repair versus replacement.

Frequently asked questions
- My furnace lights then shuts off after a minute. What is that?
- Most often a flame sensor that is dirty or failing, or a pressure switch or limit opening. It is a common repair and a quick diagnosis for a technician with a meter on the board.
- Is it worth repairing an older furnace?
- It depends on the failure, the age, and whether the heat exchanger is sound. We give you the repair price alongside what a replacement would involve so the comparison is real.
- How often should a furnace be serviced?
- Once a year, ideally in fall before the first cold snap, so ignition and safety components are verified while the weather is still mild.
