A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Granite City winters. Every visit includes a carbon monoxide safety check, 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.
No-heat calls in Granite City get priority routing over routine work during cold snaps 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.
Short-cycling or mid-cycle shutdowns often trace to the limit switch or a struggling blower before condemning the control board.
We still service older standing-pilot systems that newer ignition doesn't have.
We rule out wiring issues first to avoid overcharging for parts you don't need.
What happens from your call to heat restored.
Describe the symptom and we route the nearest tech and we'll get someone moving.
A stocked truck arrives ready to diagnose and often repair same visit.
Combustion analysis happens before any repair is quoted, then a flat-rate quote.
We re-check CO before signing off, 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
