How old is my Janitrol furnace?

1. Find the rating label: The rating plate is normally inside the furnace cabinet, on the inside of the blower or burner compartment door or on the cabinet wall behind it.
2. Take a photo of the whole label, or note the model and serial numbers.
3. Check it on Appliance Age. It is free, and no account is needed.

The rating plate is normally inside the furnace cabinet, on the inside of the blower or burner compartment door or on the cabinet wall behind it.

Keep the model, serial and any separate production code or printed date together. Not every serial number contains a publicly decodable 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.

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.

Parts that wear out most often on furnaces:

• Air filter
• Hot surface igniter
• Flame sensor
• Inducer motor
• Pressure switch
• Blower capacitor

Have the model number from the rating label ready so the parts fit.

Search our indexed notices by type, brand and optional model number, then confirm with the manufacturer.

Find the rating label (The rating plate is normally inside the furnace cabinet, on the inside of the blower or burner compartment door or on the cabinet wall behind it), then enter the serial number or a photo of the label on Appliance Age. It checks supported serial date codes or a printed date for you, free; some formats need more information.
