all the stuff for my house have already been discontinued...lol..only three years old. Really on the fence, not sure if the swap would make a noticeable difference..getting another 20k for the garage and not swapping would result in about $1000 (smaller unit, no swap charge) lower price tag.
house has a mxz 2b20na2 with head units msz ge15na and msz ge09na
proposed swap unit mxz 3c24na2
garage will have head units msz gl12na and msz gl09na, if I don't swap scaled back outdoor unit would be mxz 2c20na2
