We had Premier install the A/C system in our new home which has an industrial look like a NY loft. They installed exposed spiral wound metal duct which looks good. However they used cheap metal duct that makes load popping noises when the heat comes on in the winter. In summer we sometimes get condensation dripping from the ductwork. They send out techs who are very nice but unable to correct the problem because you can shine, shine, shine but you can't shine poop. The duct is thin cheap junk. If you use these folks stick to basic residential fiberglass duct systems. Do not let them do any exposed duct.
