If this means no heat in the house: A home with no heat is treated as urgent and prioritized, often same-day. The emergency button on the booking page gets a callback within 60 seconds.
If one of these fixes it, you owe us nothing and we are glad. If not, the next part is what the visit is for.
Yellow flame. A yellow tip means too little primary air or clogged burner ports, and clogged ports are a cleaning, not a part. If the flue is sooted or corroded the products of combustion are not leaving the house properly, which is the part that stops being about comfort.
Heat exchanger. An exchanger that rusted through was rusting for years, and what rusts it is the same thing that rusts the burners: moisture and dirty combustion. The burners come out, get cleaned, and corroded ones are replaced, always. And low gas pressure or dust on the heat transfer surfaces finishes the job; the book sets the pressure and filters the air on every heating call.
These are the causes in the manufacturers' troubleshooting charts and the trade handbooks our technicians train on, in plain words. The visit proves which one it is with a meter before anything is replaced.
Filtering every cubic foot before it reaches the cabinet is what keeps the burner clean between visits.
The repair and the replacement are always both on the paper, in writing, warranty or not.
