How old is my Ameristar furnace?

1. Find the rating label: The rating plate is normally inside the furnace cabinet, on the inside of the front door or on the blower compartment.
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 front door or on the blower compartment.

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.

22 Ameristar models are currently ENERGY STAR certified, 22 of them sold in Canada. The certified models went on the market between 2019 and 2019. An older Ameristar furnace may use more energy than today's certified models.
