I know from installing unico systems that when using high velocity systems that you are more prone to air leaks due to the higher velocity of air being moved but that is no excuse for air leakage ,if the ductwork was installed proberly the leaks would be at a mimiun ,I have used hard cast tape on all joints and seams and adjustable 90 when used ,i would think that if air leakage was such a issue one would use spriral duct and fittings but that would of course drive the jobs price up ,i have always used a mimuin of 26 gauge pipe and smoke ells and screwed and taped round pipe seams and used a hvac silcone sealant on adjustable ells and then taped with a gaskets tape usually hard cast and have never had any issues with air leakage .Things like taping abnd screwing all jointsare in my mind part of a proper install when there is alot of air leakage to me indacated a lack of attention on the installers part .Even though alot of companies throw around the word quality there main concern is quanity and money with out the 2 they would be sunk. Get a good quality gasket tape from a local hvac supply house and remove the instulation and re tape the joints including the ells if the ductwork seems oilly wipe it down with vinger to help the tape mastic join better peace and good luck clammy
