Decyphering AC Tons from model #

[trader4]

I have a RUUD UACB056JAS AC unit. I'm curious as to how many tons it is. Is there any way to decipher this from the model # or any of the other tech data on the info plate?

It was built in 1984, and yes I know I'm lucky it's still running LOL

TIA

kBtu/hr

Model Number Identification U A L C - 024 RUUD REMOTE HIGH EFFICIENCY DESIGN SERIES COOLING CONDENSING (STANDARD) C = THIRD CAPACITY UNIT DESIGN 024 = 24,000 BTU/HR [7.03 kW]

Since 1 T (refrig) --> 12 kBtu/hr, this would be 4+ T nominal.

but since they didm't make a56,000 btu unit, it is probable that the 5 is really a 3 and it's a three ton.Which, coincidentally, they did make.

I noticed the 56 being an odd number as well--more than likely right that OP misread or mistyped the model number. Good catch. :)

Then that would appear to be it. I'm sure if you either contact Ruud directly or a local dealer (which is what they may tell you to do) Monday morning they can confirm it.

It is an unusual size if so, but given the age and the lack of online data for older units at

I figured it possible even though saw the odd number as noted.

Your system is four and a half tons.

No one makes a four and a half ton unit....

[Al Moran]

Whatever. 56,000 is four and a half tons.

Actually, that would be 4-2/3 T (VBG) :) ...

Okay.

I do some Rheem stuff. What would be a RAKA-037? Rheem calls it a 3 ton, even though the model says 37K Btu's.

Stick with harassing homeowners that think you know stuff.
