what exactly are they? I have had a few customers ask me about them mainly because they believe the smaller ducts can be advantageous to having almost zero space for duct runs etc
however looking over the site and seeing pictures etc, it seems to me the units themselves take up as much or more space then a normal hvac system but i cant be sure..
can somebody who has installed both normal residential systems and these hi velocity systems, can you give me the run down from cost to install to application on these systems??
