Plastic bag and duct tape repairs on a ac duct isn’t so smart. Way to ac the attic and spend more money then what the repair could cost.
That is a shame – that is actually high quality metal duct, unlike the cheap flexible duct used in most modern homes. Here are a few points:
1. The tape is not duct tape – it’s aluminum foil tape. This is the only thing the “repair man” did right – duct tape should never be used on ducts – only aluminum foil tape. On the other hand, it is cheap foil tape, as it is not marked “UL-181”.
2. The foil tape has been applied improperly – once on , it should be smoothed with a sqeegee
3. None of the duct seams have been sealed. ALL duct seams leak unless sealed – you can use duct mastic or foil tape.
4. The ducts have no insulation. Covering these ducts with R-6 or R-8 insulation would save a lot of money.
5. The rectangular duct is a main duct and the circular duct a branch duct. It looks like the collar that joins the rectangular to circular duct has failed. The collar should be replaced, the circular duct re-attached to the new collar with sheet metal screws, all joints sealed, then everything insulated. I bet heating/cooling bills would go down at least 30%. The collar probably failed because the branch duct is hanging loose – it has no support. It should be supported with duct support tape nailed to the wood above.
6. Once again, this is very high quality, expensive metal ducting, which is hardly ever used these days. It’s heavy guage steel, not the cheap stuff you can buy at Home Depot or Lowes. It’s a shame to see it messed up like this.
yea the reason the other style call INSULATED FLEX is uses is it works better especially for feed ducts, the cheap shit has a plastic jacket while the good stuff has a metalized jacket. the round duct when installed correctly with Y’s instead of T’s is far superior in air handling capabilities, the real fail is on the system mechanics designs where there is the lack of multiple return air vents, a typical house should have 3-6 and have a quality central air filter
Way to ac the attic and spend more money then what the repair could cost. THAN, not then.
