I am adding an addition to the house and my current heating 7 cooling unit is taped out. I have a 2089sqf home and I am adding approx 1100sqf. I am being told that my current heating & cooling unit can not take additional space so I should install another unit for the addition. I would like to install in the celing but I have a vault. Can this be done? What should I be looking for as far as efficiency? Shoudl I be looking at heat pumps of gas funaces? I have a Carrier weather maker 8000 now.
Any assistance you can provide is very appreciated.
