A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Cabin John winters. Every visit includes a carbon monoxide safety check, standard, not an upsell.
Furnace failures in Cabin John 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.
A fixed price is set before repairs start.
Both fuel types get the same trained tech, no exceptions.
