A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Francisco 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.
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.
Cracked ignitors and carbon-fouled sensors cause a large share of no-heat calls, 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.
We test both before condemning the control board.
We still service older standing-pilot systems 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.
Tell us what the furnace is doing and we'll get someone moving.
A stocked truck arrives ready to diagnose and often repair same visit.
Safety and diagnostic checks come first, 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.
— 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.

Common questions before a Furnace Repair visit.
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.
A CO check is standard on every call, no upcharge.
We still service these older systems.
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 Francisco — call to confirm.
