I have gotten a lot of mixed answers and I am turning to you guys to help me make my final decision. I know I need a new Gas Furnace and A/C. I want a high eff one. but that is where it gets hard....do I want one system or two. Currently I have two 75k BTU with 1.5Ton A/C exact same systems. House is only 2,200k sq ft. Based on the tech's I have had over...one system 80k-90k BTU is plenty....so what's the problem???
THEY SHARE ONE MAIN RETURN!!!
Is that ok?
Is it true that I can't or at least don't wan't to have two variable speed furnaces on one return?
Anything is possible....but spliting the return will not be easy? That being said...am I better off paying the money to have the returns split properly...and then have two systems to offer better climate control???
