Every furnace call starts with a combustion and carbon monoxide safety check, not just a symptom fix.
Heat exchanger cracks, ignitor failures, and gas valve issues all fall within our scope.
Furnace failures carry a safety dimension — carbon monoxide and gas leaks — that most other hvac repairs don't, so the diagnostic has to start there, which is exactly why furnace repair calls in Hayward, CA get treated with urgency, not a next-available-Tuesday slot.
