Hi: Basically you got a 4 ton system on your hands. It is a high efficiency job and therefore claims a thousand btuh more than the 48k required to make up a 4 ton. 12,000 btu = 1 ton soooooooo 4 times this = 4 tons plus 1000 extra btuh claim. P.S.,,, I'm a big user of Goodman Products for long time. Say 20 years or more & I would like you to know That company gives you a lot for your buck. Jimiwane
