How old is my Daikin heat pump?
Check the rating label of your Daikin heat pump for the serial number and any printed manufacture date. Enter the details or a label photo to check supported date formats, typical service life and available recall notices.
Check your Daikin heat pump
- Find the rating label: On the side or back of the outdoor unit; ductless indoor heads also have a label under the front cover.
- Take a photo of the whole label, or note the model and serial numbers.
- Check it on Appliance Age. It is free, and no account is needed.
Where is the serial number on a Daikin heat pump?
On the side or back of the outdoor unit; ductless indoor heads also have a label under the front cover.
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 Daikin heat pump last?
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.
