Nice video. I would have liked to see the connection between the new duct work and the actual tie in to the main return.

[@pipi7731]

Exactly. I was wondering how this return air vent tied in and how the air flowed through the filter.

[@supaman881]

​@@pipi7731 if i'm not mistaken those look to be jump ducts. They move air from the bedroom into the hallway, where the air can more easily get to the central return.

[@reno911yo]

such a great quality install awesome job bro

[@blw3169]

Nice job framing in the vent intake boots. Could have used zip ties in addition to tape on the end of the ducting. You must have a return upstairs already. I need to do something similar on a 70s vintage home which was built only with heating, no return up high so AC recently installed doesn't work as well upstairs as the hot air has no where to go. I will be jumpering (3) bedrooms and maybe a hallway together and then running down a wooden chimney chase which is only used for hot water heater exhaust now to a lower attic area where I will tie into the main return.

[@FrontyMan]

Did I miss something - the part where you attached the new ducts to the existing trunkline?

[@jonasbaine3538]

That is literally only reason I clicked on video. Everything else is straightforward.

[@KentSchneeveis]

I'm sorry. My part of the job was only to do what the furnace company wanted, to connect the bedrooms to the main house where the furnace intake is.

[@maryaguilar5523]

Where does the hose I’m adding attach to in attack

[@davidserpa6738]

Should use a panduit strap at the boot to secure the duct to that boot.

[@rbnjr]

If added returns don't go thru a mechanical filter assembly then one must be added for each return? I have UV lights at the evaporator but seems like additional filters might be needed.

[@guitarfixx4652]

On this job Valley Heating uses only one filter at the furnace. And there was a permit process. The City was happy having only one filter at the furnace.

[@koreymayo8884]

Can the boots be installed without adding pieces of wood? I would think the sealant would hold it plus the grill on the other side with screws would also hold it right?

[@MrCoreyCoreyCorey]

Nice job! Dumb question - when you're up there, you're just keeping your feet/knees/weight etc on the studs and reaching to where you need to work? Did you put down a plywood board or something to perch on? I need to get up there. so far have only been brave enough to peek through the cutout! Thanks!

[@KentSchneeveis]

Yes, that’s true keeping my feet on the studs one must constantly be mindful. However, there was some plywood up there. It’s important to screw it down. Not a bad idea, for future maintenance workers. I made the mistake of not screwing it down, and it will slip!

[@MrCoreyCoreyCorey]

@@KentSchneeveis Thanks for replying, and the note about it slipping! I appreciate it.

[@ryanmcginnis2553]

Does it matter where to put the return duct in the bedroom? I'd hate to draw in cooler air from the ac vent, I'm not sure if there is a distance you'd want to keep it from, or better to put one near and exterior window or sliding door

[@KentSchneeveis]

I'm not so sure. I'll have to get back to you on that...

[@wattsupwiththat1463]

Defiantly need to separate the supply and returns. Supplies are better placed near a window or exterior wall. Returns close to the wall so they draw air from the the supply when the door is closed and from the hallway when the door is open.

[@rickavendano4762]

I need to do a similar project. All three bedroom have no return to the house. Question... can all three bedrooms be connected to one main return? All three of the bedrooms are at the end of a hallway. Hate to make a return hole for each on that hallway. Can these returns get joined together by "Y" ducts?

[@KentSchneeveis]

Hmm... that's a good question. If the main return was big, like 3 X the size of a regular return I bet that would work fine.

[@OmeedNOuhadi]

👏👏👏 I did not see the existing duct to tap into for the return. I might have missed it. Do all houses have a return in the attic even if the 2nd floor bedrooms do not have one?

[@KentSchneeveis]

Hi - Im not sure about all the details. The HVAC company installing the new heating/air conditioning system asked the home owner to add return air for the bedrooms. They were the brains on the job. I was merely doing what I was told. Ask Valley Heating... www.valleyheating.com/

[@OmeedNOuhadi]

@@KentSchneeveis Awesome! It's okay because I went into my attic & it was empty, no vents😅to add a return to over the room.

[@Mattox1231]

Those look to be jump ducts. They move air from the bedroom into the hallway, where the air can more easily get to the central return.

Mike - Well said. That's exactly what these ducts are doing... Those look to be jump ducts. Moving air from the bedroom into the hallway, where the air can more easily get to the central return. Thanks for the helpful comment.

[@gwendolynfoster8305]

Why are there no filters on your return duct vents?

[@KentSchneeveis]

Because the filter is already on the main intake of the furnace.

[@michellemajako]

How did you connect it to the system though?

[@guitarfixx4652]

The house IS the system.

[@KentSchneeveis]

Those are jump ducts. They move air from the bedrooms into the hallway, where the air can more easily get to the central return.

[@Samhain2323]

Why did you decide not to show how and where to connect the other end ???

[@guitarfixx4652]

I was just connecting the bedrooms to the main part of the house where the furnace is. That was the idea. So the air in the bedrooms could return to the intake of the furnace. That’s what the return air vents were all about. I hope this answers your question. 🧐

[@Dontleavemedimi]

Question: Are you bypassing the filter by installing those returns

[@KentSchneeveis]

Not sure. Valley Heating installed a new modern furnace that does air conditioning too. I just did what they told me to do. It was a team thing... and a good learning opportunity for me . But not sure about the particulars. Sorry I can't be more helpful.

[@sigmapi1989]

No likely, the return air normally goes to a junction box that then goes through the filter.

[@Dontleavemedimi]

@@sigmapi1989 well done

[@steve6903]

You never showed how or where the other end of the duct was connected into the existing system.

[@lilweezy110]

I added a media filter in my house and added the duct to the media filter better airflow. More air that goes into furnace more air that gets supplied to the house.

[@jonasbaine3538]

Most important part that I missed was how to connect new return lines into existing ductwork.

[@KentSchneeveis]

[@jonasbaine3538]

@@KentSchneeveis i think what many comments are asking is did you cut open the existing return duct work going into furnace and put some kind of adapter to accept the new return airflow? your video shows where the air enters the return vent but where does it join the existing system?

[@KentSchneeveis]

Valley Heating installed the new furnace onto the existing intake ducting. That didn’t change. That all stayed the same.

[@jonasbaine3538]

@@KentSchneeveis Ok. Thanks.

[@wattsupwiththat1463]

Is this a return or a air jump? I didn't see where you tied it into the return line.

[@lilweezy110]

Why use tape use 24in nylon zip ties. Zip tie the duct and insulation on the register box.

[@KentSchneeveis]

Each to his or her own. For me, I trust the tape more than the zip tie.

[@lilweezy110]

@@KentSchneeveis im an hvac contractor i ziptie the duct to the boot ziptie the insulation and then tape the insulation to the boot reason why i do it is the tempreature changes in an attic can cause the stickiness of the tape to lose its strength over time.

[@KentSchneeveis]

Noted... Good to know. Thanks @@lilweezy110

[@juelzd7172]

Video doesn’t show what the return ducts connect to. Kinda hard to see what they do 😮

[@KentSchneeveis]

The return air ducts connect the bedrooms to the rest of the house.

[@KentSchneeveis]

These are jump ducts. They move air from the bedroom into the hallway, where the air can more easily get to the central return.

[@juelzd7172]

@@KentSchneeveis ok thank you for the reply. Nice work to remove the heat from the bedrooms more efficiently.

[@74betty]

​@KentSchneeveis what's a jump duct vs a duct that doesn't go into the hallway? My hvac guy said he's going to run it from the basement where the system is and up thru the floor, into the bedroom and it will be at the top of the wall (nothing connecting to the hallway)

[@KentSchneeveis]

As long as it connects in the house where the main furnace is that fine.
