How old is my Ameristar heat pump?

1. Find the rating label: The rating plate is usually on a side panel of the outdoor unit, often near the electrical service panel.
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 usually on a side panel of the outdoor unit, often near the electrical service panel.

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.

Heat Pumps typically last 10 to 15 years. Use, water quality and maintenance matter more than the brand. Clean indoor filters monthly in heavy use and keep snow and ice clear of the outdoor unit.

37 Ameristar models are currently ENERGY STAR certified. The certified models went on the market between 2023 and 2026. An older Ameristar heat pump may use more energy than today's certified models.
