A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Sunnyside winters. A CO check happens on every call, standard, not an upsell.

Furnace failures in Sunnyside 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.
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.
Short-cycling or mid-cycle shutdowns often trace to the limit switch or a struggling blower before condemning the control board.
We still service older standing-pilot systems that newer ignition doesn't have.
We rule out wiring issues first to avoid overcharging for parts you don't need.

Feedback from completed furnace repairs.
Pilot light kept going out on our older furnace every few days. Tech identified a failing thermocouple that two other companies had overlooked.
