Carrier Date

Carrier A/C Unit

Model- 38ER036300

S/N- 0461363

Anybody got a date on this unit? The furnace was a Carrier 1988 model. This unit looks about the same. Is it a 3 ton or 2.5 ton?

I know. I've got to purchase a Preston's Guide. ASHI has for them 80 bucks, anyone found it cheaper than that?

Thanks,

Tsk,

Shame. You haven't been paying attention. Go to this thread from several weeks ago and look at my post on page 2. Jeesh, wudueyehaftado? [:-cry]

Anyway to make a post sticky? That way the post, like the one your refering to, can be pinned to the top of the forum.

Carrier: Age is incorporated into the serial number. Through 1969, the first digit of the serial number indicates the year of manufacture. Example: 3xxxxxx = 1963, 4xxxxxx = 1964, etc.

1970 and later, a letter followed by a number indicates the month and year of manufacture. Example: A1 = January 1971, B1 = February 1971, C4 = March 1974 etc.

A = Jan

B = Feb

C = Mar

D = Apr

E = May

F = Jun

G = Jul

H = Aug

J = Sep

K = Oct

L = Nov

M = Dec

I am assuming the unit is likely from the 80's and installed with the furnace in 1988.

According to your post from Home Tech if it is indeed from the 80's my serial number should begin with a letter and mine didn't, it begins with a zero. So I still don't know.

Done

OT - OF!!!

It's a 3 ton, the 036 stands for 36,000 BTUS. I'll dig out my Prestons a little later.

Thanks Terry.

hausdok, go take some deep breaths, hold and slowly release.

Are you quite sure you didn't misread a D as a zero? D4 would have been April 1974 according to the HomeTech info or perhaps 84 or 94 if it goes in 10 year cycles.

Hi to all,

Prestons list that unit as being a 1984, and yes as other have stated it is a 3 ton unit.

So,

Looks like they use a 10 year cycle beginning in '71.

I appreciate the help everyone.

By the way I am ordering a Preston's Guide today, I should have ordered one long ago.

By the way the unit really cooled well for that age. I took a temperature at the supply of 52 degrees.

Case closed.
