A furnace that won't light or keeps shutting off needs real diagnosis, not another reset. A CO check happens on every call, standard, not an upsell.
Furnace failures in Los Alamos 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.
Every repair includes a CO check, not optional.
No-heat calls in Los Alamos get priority routing over routine work during cold snaps when it's cold.
A fixed price is set before repairs start.
Both fuel types get the same trained tech, 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.
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.
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.
— 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.

What Los Alamos customers ask most.
Clicking without ignition often points to the ignitor, but we confirm with a resistance test before quoting.
Yes — it can let combustion gases into breathing air, we won't run a confirmed-cracked unit, taken seriously.
Yes, included at no extra charge, no upcharge.
We still service these older systems.
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.
