What furnace repair involves
A furnace repair visit is a diagnostic first. We read the control board, check gas pressure and temperature rise, and verify the safeties are doing their job instead of being bypassed by a previous repair.
Diagnosis and repair of gas, propane and oil furnaces — ignition, flame sensors, blowers, boards and heat exchangers.
What we usually get called for
- Blower runs but the air is cold
- Furnace lights, then shuts down after a few seconds
- Clicking or repeated attempts to ignite
- Burning or hot-metal smell when it runs
- Thermostat calls for heat and nothing happens
The repair itself
Most repairs come down to ignitors, flame sensors, pressure switches, inducer motors, blower motors or capacitors, control boards, and gas valves. We show you the failed part and explain what it does before we install a replacement.
If it's time for new equipment
If the heat exchanger is cracked or the unit is past 20 years with repeated failures, we'll say so plainly and quote a replacement. If it has years left, we'll tell you that too — that's the more common answer.
Questions from Byram homeowners
- How long does a furnace repair take?
- Most are an hour or two once the diagnosis is done. Parts that have to be ordered are the main reason a job stretches past one visit.
- Is it worth repairing an older furnace?
- Often yes. Age alone doesn't condemn a furnace — a cracked heat exchanger or repeated major failures do.
