Hi, I am new to this site and to HVAC issues. I am the owner of a 1923 colonial, three floors, and want to install central air. We have no duct work. I have just gotten a bid from a highly respected contractor who has nothing good to say about high velocity systems. He said it will be less aesthetically pleasing and probably more expensive than the traditional system (with hard duct work). Running the system he suggests will take some of my closet space and there will be a build out in one room.
I wonder if someone would be willing to give me the pros and cons of these products. Before speaking to this guy, I was thinking that the high velocity system was probably the way to go.
