As you know we have been pulling out our hair on this AC stuff. Current situation is 2T.up and 3T. down.
Currently we have 1 1/2 story house. 2362 sq ft...manual J we come out with 4 T. zoned Infinity to cover both floors. 2nd floor is under 700 sq. ft. The numbers work out good. But.............now we are getting cold/warm feet.
Ok...we can go with 2 separate units if we use our old lineset. We would have to have 2T. upstairs, which I know is overkill. Then we would need 3T. down cuz that is what we need down.
All the pros here recommend going with 2 units (New Orleans - Biloxi area). We can't get the sizing balance right with 2.
BTW.........we are talking the Infinity Heat Pump and Air Handler and their zoning system.
Not so sure what we use if we go back to two units. 2T upstairs is like a meat locker.
Our contractor says he can make one 4 t. system work with the zoning. After reading all the comments here we are scared off of even trying.
What would you do given this scenario
BTW...we are talking about the Infinity Heat Pump, Infin.Air Handler and zoning system...were we to go with one unit.
With 2 units....who knows...maybe 2 Comfort or Performance
