You cannot tell the manufacture date from a model number, only from the serial number. Try contacting manufacture with the serial number...

How do i find the year my a/c unit was made ?

Find the name plate data and look at the serial number. It is normally a 9 or 10 digit number. The first two number is the year the unit was made and the next two numbers is the week manufactured. for example 0615xxxxxxxxxx is the year 2006 and the 15th week. If the name plate data is fades, look at the paper posted inside the control section. If it is still there you should be able to get the model and serial number.

How do tell how old the unit is

You will need to look at the serial number of the unit. There may also be a date code on the unit itself. If there is not a date code, then the serial number will contain the year of manufacture. Its typically within the first 4 letters or numbers of the serial number. Look for any numbers that resemble a year that may suit the age of the unit. If you cannot determine age, gather the model/serial and call a local parts house and ask for the year of manufacture. They should have no problems attaining that information for you.

Year of equipment based on serial/model#?

The serial number on Carrier units tell you when they were built. The first two digits tell you what week they were manufactured. Digits 3 and 4 tell you the year.

How old is my Technics SL 1210 Mk2

Here's some information for you. Since your unit is a SL1210MK2, it may be harder to determine the age of the unit:

It is possible to tell the year (and the month) when the SL-1200 was manufactured from the serial number on the back or bottom of the turntable. SL-1200 serial numbers are in two different formats, depending on the date of manufacture. It isn't exactly possible to determine the decade in which the SL-1200 in question was manufactured, as the serial number contains only the last digit of the year. If the year digit is 8, the turntable may have been manufactured in 1978, 1988 or 1998. If the year digit is 0, the turntable may have been manufactured in 1980, 1990 or 2000. One rule of thumb is that old-format serial numbers belong to SL-1200s manufactured during the 1970s and 1980s, while new-format serial numbers belong to SL-1200s manufactured during the 1990s and beyond.
Old-format serial number: NHOJF20765 (SL-1200 manufactured 1982)
The first digit shows the year when the SL-1200 was manufactured. These serial numbers contain no indication of the month of manufacture. It should be noted that serial numbers in this format contain no letters following digits.
New-format serial number: GE4FB001154 (SL-1200 manufactured June 2004)
The first digit shows the year when the SL-1200 was manufactured, while the month of manufacture is indicated by the letter following it. Months are coded as letters between A and L inclusive; A indicates January, B indicates February, and so on.
In addition to the above, all the SL-1200MK2s from the 70's and early 80's have a 4 inch diameter plate where the RCA and ground wires enter the chassis in the rubber base of the unit. The later models have a smaller hole through which the wires enter the unit.
