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 Greenfield 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.
