A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Onset winters. Every visit includes a carbon monoxide safety check, standard, not an upsell.
Furnace failures in Onset 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.
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.
Ignitor or heat exchanger, the price is quoted and approved before work begins.
Our techs are trained equally on gas furnaces and electric heat strips, no exceptions.
The most common furnace failure points.
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.
We inspect carefully with proper equipment rather than assuming based on age.
We test both before condemning the control board.
Older Onset 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.
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.
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.
— H. Delacroix, homeowner
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.

Yes, included at no extra charge, no upcharge.
Yes — thermocouple and draft-related repairs are covered.
We prioritize no-heat situations even during high demand.
Uncommon parts might mean a follow-up visit to finish the repair.
