A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Sunset 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.
Safety and accuracy on every heating call.
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.
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.
A cracked heat exchanger can leak combustion byproducts into the airflow — we inspect with a scope and analyzer 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.
Older Sunset 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.

A CO check is standard on every call, no upcharge.
Yes — thermocouple and draft-related repairs are covered.
No-heat calls get priority routing, usually same-day even during high demand.
Common parts are stocked, rare ones may need next-day ordering to finish the repair.
We dispatch heating techs throughout Sunset — call to confirm.
