What is the size in tonage of model number 38TG048310

LRA on the data tag stands for "locked rotor amps" and has nothing to do with tonnage. In the model # there should be a number to use. And divide that # by 12 (12,000 btu/ton). So if I had a PFG24H200 it would be the "24"and a 2 ton unit

It will usually be in the model number on the unit. You will have to supply the model number and possibly the serial number for us to see. Thanks!

It's a 4 ton.

should be able to read the model number right off of the compressor......(the big black dome shaped thing). That model number tells the btu/hp which translates to tonage. It also lists the electrical data such as voltage.

Hi, the tonnage of your unit is a 3 Ton unit. There are 12,000 btu's per ton of cooling, so your model number has a a36, so 3 x 12 = 36 which is 36 = 3 tons of cooling.

Sounds like this is serial number. Look again. On Carrier it will ahve CKC048 or something like that. Just divide 12 into that number for your tonnagr. Rus

Its say 7100 BTU/hr

its a 3 ton unit manufactured in 2005 
the 36 in the model number indicates tonnage 12,000 btu's to a ton times 3 equals 36
the 2005 in the serial indicates year made not sure what month but if i had to guess i'd say May of '05
Thanks Peyton

the higher the seer the more efficent it is no matter the tonage of the unit

make sure that the tonage is correctly sized for the home rule of thumb is if the home is insulsted properly 600 sq feeet per ton
oversizing creates shot cycles real cool then warm real cool then warm, under size unit runs all the time
