A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Mercer 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. 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.
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 Mercer 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.
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.
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.
