Where the current location of the heat register in our master bedroom is does not work, it is either covered by our bed or covered by a dresser. It is not located above a window either, but that is what I would like to do but want opinions from some that are knowledgeable in HVAC work.

What would be the best way to get the master bedroom register where I want? Can I use the duct work pipe for register 2 of 2 in the kitchen and extend it all the way to the master bedroom?

What other options do I have? Could I possible get rid of some of the round duct work and extend the main trunk line and run my lines off it?

If I can extend the duct off this boot, what is the proper way to, do they make a proper piece or will it need to be cut to fit?

Extending/taping off of a round supply run will generally leave one or the other supply without enough air.

Extend the main trunk line, and tap off of it.

I would not steal a duct from the kitchen.

The duct you are talking about extending, is that the one that needs moved? You could remove the register it feeds, then put a radiused elbow on it and run it to the new location.

I thought the more bends and turns the less air? Right now the register I want to relocated feeds the master bedroom and the bathroom. I want the master bedroom relocated, but the bathroom register to stay.

If I were to use the existing duct and extend it, that would require a 45 degree turn to the left for about 15 feet then another 45 back to the right and end right at my location.


The reason why I brought up taking one from the kitchen is because it is a straight shot to where I want to go.

Don't tap the kitchen duct. It's hard to tell from the picture, but you cab either just extend your current bedroom duct or remove/relocate sections, so that you can parallel the kitchen duct.

Yes, more bends does reduce airflow, but not as much as flexible fab5 duct. It's smooth metal, so the restriction is minimal, and much better then double tapping the kitchen duct.

Cheers!

My mistake, I missed the part about the bathroom register. I still think it is best to extend the original duct. That duct main was sized to handle the correct amount of air (hopefully).

What supers05 says below explains it. Smooth duct and solid, radiused turns have minimal pressure loss. And yes flex duct has terrible pressure drop.

I have not done anything with this project as of yet. This run of duct work is 7" I was thinking I need a 7"x7"x7" wye. Have the 2nd go to the master bedroom and the 3rd side go to the bathroom, and also install a damper for the bathroom so it directs most air into the master.

I am having trouble finding the correct size wye. I also noticed I have 7", 8" and some 6" duct work throughout the house. Should it all be the same size?

Should all the duct size be the same on this run?

This is what I would like to do!Make the truck supply similar to this and not have all the round duct come straight off the plenum which creates a bunch of bends and curves. This would make it simpler!

Wonder what it would cost for an HVAC guy to run the supply trunk?

 

[supers05]

In an unfinished basement like that, maybe a few hours of labour and materials. Would be relatively cheap. You can buy that square duct. Lots of tin bangers around here that'll sell to just about anyone.

Will vary with the area.

Call a couple places and get prices.

Here is what my plenum looks like, it measures around 16" wide.

Im trying to figure out if this is something I could DIY. (Ive never hired a contractor yet.)

What all information must I find out before determining what size supply trunk I will need to install?

I did some measuring, I will need a 2 way supply trunk one way 13' and the other 14'

Right now there is 1 register heating/cooling the basement, I have plans to finish one day. So right now I have 7 registers coming off of 5 feed lines.

most of the duct work is 7" and it fits perfect between the floor joists but it seems to be damn hard to find a good supply!

 

[supers05]

It's DIY'able. You'll need some tin-snips, self tapping pan screws, misc screw drivers, hammer, metal strapping (hangers), the ductwork, foil tape(optional), some "S" and "Drive" (Home Depot might have these... Your return duct has them between joints, if you need an example)

Cheers!

Need to determine how much air each supply run is moving, to determine what size trunk line to run.

Sorry for my ignorance but how is this done?

 

[cincinnati guy]

Well I finally relocated the master bedroom vent. We ended up relocating it under the bedroom windows.

This supplies the bathroom and master bedroom, we typically keep the bathroom vent closed, hope this will keep the bedroom cool enough!

I really do not like how the vent for the bathroom is cut to fit into the pipe but I guess ill live with it.
Does this look right guys?

 

[beenthere]

The way it was done looks good from here.

How is the air flow.

 

[supers05]

Looks like a pro job.

You'll get slightly more air if you tape the seams. I like foil back tape.

Cheers!

 

[cincinnati guy]

The seams are taped, but I did not tape where the elbow pieces twist. Maybe Ill do that.

Air Flow? Well lets just say I wish it had a bit more air flow. It is also the longest run in the house.

 

[supers05]

Ah, I missed the tape the first time I looked. That should be adequate.

The els and their configuration alone, are equal to about 100' of duct length.
