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.
Furnace failures in Sheldon cluster around a handful of parts — ignitors, flame sensors, gas valves, heat exchangers. Each gets tested with a multimeter and combustion analyzer, not replaced on a hunch, not parts-cannon guessing.
Safety and accuracy on every heating call.
A combustion analyzer reading for dangerous CO levels is part of every visit, not optional.
No-heat calls in Sheldon get priority routing over routine work during cold snaps when it's cold.
A fixed price is set before repairs start.
Our techs are trained equally on gas furnaces and electric heat strips, no exceptions.
Six repairs that cover most of our winter calls.
These two parts are behind most no-heat visits, usually a same-visit fix.
We test actual response and pressure output rather than replacing an expensive part on a hunch before we recommend replacing it.
A cracked heat exchanger can leak combustion byproducts into the airflow — we inspect with a scope and analyzer rather than assuming based on age.
Short-cycling or mid-cycle shutdowns often trace to the limit switch or a struggling blower before condemning the control board.
Older Sheldon furnaces with standing pilots have their own failure points — thermocouples, pilot orifices, draft issues that newer ignition doesn't have.
Zero response from the furnace can mean a wiring fault, not a furnace failure to avoid overcharging for parts you don't need.

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.
