Where is the serial number on a Miller furnace?
The model and serial label is inside the furnace; open the front door panel of the cabinet to find it.
Keep the model, serial and any separate production code or printed date together. Not every serial number contains a publicly decodable date.
Checking the manufacture date
Use the format that belongs to this product family. A printed production date, a supported serial code or manufacturer confirmation can establish the age. Repeating year codes may leave more than one possible year; a model-series introduction date helps narrow the range but does not date your individual unit.
How long does a Miller furnace last?
Furnaces typically last 15 to 25 years. Use, water quality and maintenance matter more than the brand. Change the filter every one to three months and have it serviced yearly.
