A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Bunker Hill winters. 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. Each gets tested with a multimeter and combustion analyzer, not replaced on a hunch, not parts-cannon guessing.
What doesn't change from visit to visit.
Every repair includes a CO check, not optional.
We bump no-heat calls ahead of routine visits when it's cold.
Ignitor or heat exchanger, the price is quoted and approved before work begins.
Both fuel types get the same trained tech, no exceptions.
The most common furnace failure points.
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.
We inspect carefully with proper equipment rather than assuming based on age.
We test both before condemning the control board.
Older Bunker Hill 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.

What happens from your call to heat restored.
Tell us what the furnace is doing 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.
Recent reviews from winter heating calls.
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.
