How to Find the Brand of Your Furnace or Boiler
Most units have a rating plate or sticker with the manufacturer and model. On a warm air furnace, it’s usually on the cabinet or just inside the front access panel. On a boiler, look on the side of the jacket. The oil burner, the part bolted to the front with the motor and the transformer, has its own label with its brand.
You don’t need to know any of this to book. If you do have it handy, add the brand and model in the notes on the request form so Max knows what to expect.
