A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Earth City winters. A CO check happens on every call, standard, not an upsell.
Furnace failures in Earth City cluster around a handful of parts — ignitors, flame sensors, gas valves, heat exchangers. We test with real equipment, not parts-cannon guessing.
What doesn't change from visit to visit.
A combustion analyzer reading for dangerous CO levels is part of every visit, not optional.
We bump no-heat calls ahead of routine visits 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.
Gas valve testing confirms the fault 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.
We test both before condemning the control board.
Older Earth City 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.
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.
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.

Clicking without ignition often points to the ignitor, but we confirm with a resistance test before quoting.
It's a real safety concern, taken seriously.
Yes, included at no extra charge, no upcharge.

No-heat calls get priority routing, usually same-day even during high demand.
Uncommon parts might mean a follow-up visit to finish the repair.
