Is "taping off" the end of a duct considered a proper way to cap a duct?

A company(not the original installers) came out to inspect our air unit and duct work up in the attic today and explained to me that a particular duct should have been capped & sealed using some type of metal capping rather than being taped off and is contributing to low air flow to my daughter's room. He stated that there was no reason for the duct to just be hacked off at the end unless there was some sort of problem. He suggested I get a hold of the original installers to have them come out and fix it because taping it off is considered a "no... no" in the industry and he doesn't understand how it passed inspection when we moved 4 1/2 years ago. We are the original owners of the house and the only inspection performed was by the builder who allowed many things to pass that shouldn't have.

I've contacted the original installers who say they'll come out to inspect it, but if everything looks alright, then we have to pay them $75 for the inspection. I'm worried that they are going to try to tell me that this is normal when in fact it might not be.

Is there a proper way to cap a duct in the industry? If so, is taping it off considered normal or to code?

The inspector today says that the flex leading to my daughter's room, attached a foot to the right of the hacked off and taped part, should have been attached to the end of that taped part and he wants to relocate it back to the taped area and seal off where he took it from. Is this considered an appropriate solution to the airflow problem in this room?

Any information would be helpful. Thank you.
 
Taking a branch duct of the end of a trunk duct is not considered proper,usually results in more air flow to that branch.

That said it's somtimes used to solve a branch issue with low air flow.

Chances are your ducts are undersized,which results in low air flow to the rooms farthest from the indoor unit.

Tell us more,sizes of ducts,equipment model numbers ,post pics if you can.

The hacked up duct was probably done this way for a quick fix. It shouldn't be taking air from other room(s). The proper way to fix it is to cap it off .

If your daughters room isn't comfortable it may need...
1) a bigger duct
2) or the door may be being closed too often.(this will affect the temp. in the room)

Good luck!

I'm sorry, I'm a bit new to the duct/AC terminology.

I'm not sure the sizes, however, to describe it further, I believe it's a trunk duct that comes to a complete halt and is hacked off and taped.

To the right of it, a foot away from the "hack job" is a branch duct leading to my daughter's room. To the left of it, are two smaller branch ducts, one leading to the laundry room, the other leading to a small bathroom.

Also, the original installers are willing to fix it if it is considered something to be not industry standard, but I'm thinking, they are going to come out here, tell me that taping it was the right thing to do and charge me for the information without fixing it, when I have another company telling me that either way, it should have been capped using metal, not tape.

My brother happens to live next door, same builder, same installer, with the same exact house. We went exploring in his attic this afternoon and there were no hack jobs up there. Every single trunk and branch duct lead to a room.

Yes, having someone come out to cap the trunk properly will fix most of your problem.:)

In addition, the static pressure just went to hell in a handbasket by taking a duct off the end cap.:eek:


How so,increased airflow to that tap/branch,reduces the static?
