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.
What we usually get called for
- Short cycling — on and off every few minutes
- Loud bang or rumble at start-up
- Rooms furthest from the furnace never warm up
- Grinding or squealing from the blower compartment
- Furnace runs constantly but never reaches the set temperature
The repair itself
After the repair we run the furnace through a full cycle and check temperature rise, static pressure and draft. A furnace that starts is not the same as a furnace that's right.
If it's time for new equipment
We don't condemn furnaces to sell equipment. When a replacement is genuinely the right call, you'll get the reason, the options, and a price — with no pressure to decide on the spot.
Questions from Andover 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.
