Pictures of ways to support ductwork in an attic.

Wrap the insulation around the duct and then pinch the seam closed. Foam tubing or fiberglass will work but it s also possible to buy pre insulated 4 duct. Attic hvac systems save space. Secure the insulation with short strips of foil tape.

Recently i had another hvac company come out and put in a new bathroom vent and they told me they believed the duct work was full of water. Repeat to insulate the remaining ducts. Well mainly it s a way to save space. Well in the comments dave roberts a senior engineer at the national renewable energy lab nrel wrote about a paper he co authored last year and included a link to it.

Always insulate the duct to prevent condensation problems as the warm air will be potentially running through cold ductwork. Remember that article i wrote about ducts installed against the roof deck and how i said it was probably the absolute worst single location for installing ducts. To install preformed duct insulation start by disconnecting an elbow to expose the end of the duct. Flex duct requires the correct support to ensure it does not restrict air as it flows from the air conditioning unit to the registers distributing air throughout.

Smooth rigid ducts with tape or mastic around all joints will prevent air leakage. Apply a long strip of foil tape along the seam in the insulation. So why put an hvac system up in the attic at all. It was new when the ac was put in 7 years ago.

The attic ductwork is flex duct work. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
