On an air conditioner or heat pump, look for the data plate on the side or rear of the outdoor unit. On a furnace, open the upper front door — the plate is inside the cabinet.

How to decode a Amana serial number

Find the 10-digit all-numeric serial number.
First two digits = year.
Next two digits = month (01–12).

Goodman and Daikin use the same format (Amana built by Goodman since 1997).

What your unit's age means

Typical lifespan for residential HVAC is 15–20 years. Under 10 years: repair with an OEM part. 10–15 years: repairs usually still win. Past 15 years: compare repair vs replacement.

R-22 warning: if your Amana AC or heat pump was manufactured before 2010, it likely runs phased-out R-22 refrigerant.
