A furnace that won't light or keeps shutting off needs real diagnosis, not another reset. A CO check happens on every call, standard, not an upsell.
A short list of components causes most Furnace Repair calls: ignitor, flame sensor, gas valve, heat exchanger. We test with real equipment, not parts-cannon guessing.
Safety and accuracy on every heating call.
Every repair includes a CO check, not optional.
We bump no-heat calls ahead of routine visits when it's cold.
A fixed price is set before repairs start.
Both fuel types get the same trained tech, no exceptions.
Six repairs that cover most of our winter calls.
Cracked ignitors and carbon-fouled sensors cause a large share of no-heat calls, usually a same-visit fix.
Gas valve testing confirms the fault before we recommend replacing it.
We inspect carefully with proper equipment rather than assuming based on age.
We test both before condemning the control board.
Older Derby furnaces with standing pilots have their own failure points — thermocouples, pilot orifices, draft issues that newer ignition doesn't have.
We rule out wiring issues first to avoid overcharging for parts you don't need.
Four steps, safety checked at every one.
Describe the symptom and we route the nearest tech and we'll get someone moving.
Truck arrives stocked with common ignitor, flame sensor, and control parts ready to diagnose and often repair same visit.
Combustion analysis happens before any repair is quoted, then a flat-rate quote.
Most repairs finish same visit, with a final CO check before we leave, backed by warranty.
Feedback from completed furnace repairs.
Pilot light kept going out on our older furnace every few days. Tech identified a failing thermocouple that two other companies had overlooked.

Furnace made a loud bang on startup that scared the whole family. Turned out to be a delayed ignition issue from a dirty burner, cleaned and resolved same visit.
— F. Ibekwe, homeowner
Called about a gas smell near the furnace closet and they had someone here within the hour to confirm it was safe before doing any repair work.
— Q. Whitmore, homeowner
Landlord here with an older building, they've kept three separate furnace units running through two winters without a single emergency callout.
