Every furnace call starts with a combustion and carbon monoxide safety check, not just a symptom fix.

If you're dealing with a pilot light that won't stay lit, an ignitor that clicks but never catches, or a furnace that runs but blows cold air, you already know 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.
