What furnace repair involves
Furnace repair means finding the point where the sequence breaks: call for heat, inducer, pressure switch, ignition, flame proof, blower. We follow that chain in order rather than guessing at the most expensive part.
Diagnosis and repair of gas, propane and oil furnaces — ignition, flame sensors, blowers, boards and heat exchangers.
Common problems and warning signs
- Yellow or lazy flame instead of steady blue
- Rising fuel bills with no change in the weather
- Water pooling near a high-efficiency unit
- Frequent tripped limit switches or a reset button that keeps popping
- Soot or dust around the registers
How we repair it
We stock the wear items — ignitors, sensors, capacitors, limit switches, thermocouples — so a large share of no-heat calls get finished in one visit. Anything specialty gets ordered with a firm timeline, not a maybe.
Repair or replace?
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 Lafayette 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.
