Amana used this manufacturing date format from July 1987 through September 1994, and then again from January 1996 onward. The available Amana records do not explain how HVAC units made during the 15 months between those periods were dated. A number shaped like 9506 cannot be treated as June 1995 without a record confirming that the same format still applied.
This rule is for Amana furnaces, central air conditioners, heat pumps, and air handlers. It does not apply to AH, AE, or PB room and through the wall air conditioners. Appliage recognizes those model prefixes but does not treat their first four serial digits as a Goodman HVAC date. For an Amana refrigerator, range, microwave, dishwasher, washer, or dryer, see the Amana serial number lookup instead.
Find the Age of Your Amana HVAC Unit with Appliage
Enter the ten digit Amana HVAC serial number. You do not need the model number for this calculation. When the opening year and month fall inside either Amana period, Appliage returns one manufacture month and an estimated age.
Use the Plate on the Unit You Want to Check
On an air conditioner or heat pump, the plate is on the back or side of the outdoor cabinet near the refrigerant valves. A furnace or air handler label is usually behind its removable front door. Copy the ten digits beside Serial No. or S/N.
The serial is numeric. On a worn plate, make sure a faded zero has not been copied as the letter O.
Enter All Ten Digits
Positions 1 and 2 give the year, and positions 3 and 4 give the month. Appliage compares that date with the two documented Amana periods. The final six digits identify the unit and do not influence the manufacture date.

Why 9506123456 Does Not Mean June 1995
The opening digits look like 95 | 06, but their appearance is not enough to prove a date. The earlier Amana records stop at September 1994, and the later records start in January 1996. No published rule states that 95 is a year code or that 06 is a month code during the gap.
Appliage therefore returns no age for 9506123456. The same result appears for a month code of 00 or 13 through 99, and for a date before July 1987.
Examples from Both Amana HVAC Periods
Amana HVAC Serial Number Example 1: 9601123456
Group the serial as 96 | 01 | 123456. The code 96 means 1996, 01 means January, and 123456 identifies the unit. January 1996 is the first month of the later Amana period. The manufacture date is January 1996.
Amana HVAC Serial Number Example 2: 9108033656
Group the serial as 91 | 08 | 033656. The code 91 means 1991, 08 means August, and 033656 identifies the unit. August 1991 falls inside the earlier Amana period, so the manufacture date is August 1991.
Why Newer Amana HVAC Serials Look Like Goodman Serials
Goodman Manufacturing acquired Amana’s heating and air conditioning business in 1997. When Goodman sold the Amana household appliance business to Maytag in 2001, it kept the Amana HVAC product name. This is why later Amana furnaces, air conditioners, and heat pumps use the same ten digit YYMM serial format found on Goodman HVAC equipment.
For both HVAC brands, the first two digits give the year, the next two give the month, and the final six identify the individual unit. The brand name on the rating plate still matters. Select Amana HVAC for an Amana furnace, air conditioner, heat pump, or air handler, and select Goodman when the plate says Goodman.
The earlier Amana dates come from Amana records, not from the later Goodman relationship. Federal recall records confirm the YYMM format from July 1987 through September 1994, years before Goodman acquired the HVAC business. This date range applies only to Amana HVAC equipment. If the rating plate says Goodman, choose Goodman in Appliage instead.
