Just what I needed. Great teaching. Thank you
Thank you for your feedback!
*We're very happy with the unit. Pretty Easy to instal **Fastly.Cool** too.*
I would not recommend putting those plastic anchors that close to the edge of the drywall. There is a very good chance you can blow out the drywall in that spot. I would recommend framing out around the vent opening with with 2x4s because that whole opening is now a weak spot in the wall.
I can't believe the silly questions here. The furnace is above the original hole on a platform in a little closet hence the high door. The bottom of the furnace where the air filter goes sucks air into the furnace from the hallway into the original vent below the door and now also the new one this awesome dude just made
Thank you for your feedback and understanding of the purpose for the project! Thank you!
Love checking for level AFTER screwing it in! My man!
I noticed that too. lol
thanks for the video ,where do i get the bar one ? thanks
Do Ducting Cooler have more cool air and do they cool whole room and are they cooler than AC and cool the entire room
I too have this set up. However, my return is much larger. My concern is that this return has just been rebuilt and it has a plywood roof (bad off gassing)and some black coated insulation all around and a concrete floor. Sure, I have a filter right behind the grille, but what good does that do if the air goes right into this toxic box? I have just cleaned it, it was left filthy. Am I missing something here? Is this not the air that gets cooled and circulated through out the house?
Plywood is fine. The whole off gassing thing is a bunch of fear mongering about nothing. Fear is how politicians get you to pass laws that take your rights away and make them money. There is a whole lot of insider trading going on whenever these new "safer" products get mandated by government.
Thanks for this.
Thank you!
We recently had a new return vent added beneath a new furnace, just as you did here, in the exact same location. A bad, musty smell has been coming from this new return vent now for weeks. Any idea what this musty smell could be? It's worse when the heater runs. It's a brand new system, new filter beneath the furnace, all ducts recently cleaned as well.
Could it be the condensation pump or the pipe connected to the pump? Mine was completely clogged with algae and gunk
Quick question. My home has a similar setup. Inside my return is just dirt. Do I need to line the inside with some type of insulation to keep the system from sucking up dirt or is that what the filter is for?
Thank you for watching. The bottom of the return in our house is concrete. So I didn't need to cover it. The filter will keep all the dirt out of the furnace. But if your's is a dirt floor, then I would suggest covering the dirt with plastic sheet and some insulation for better efficiency of the furnace.
@@DIYProjectsByDave Thank you very much sir.
I have a raised ranch where my return is in the hallway. the vent opening was 2x2 but the vent was old and damaged I bought a new vent that's 2x1 cuz that's all I could find at lowes or home depot. Now it seem to not allow enough airflow in cuz it humms and whistles. My furnace is in the basement laundry room. Can I just add another vent off the same duck down there? Or will it cause problems?
No answer to this question! It's very good question I am interested to know the answer here I would like to add more air flow myself.
@@spersaud424 I ended up doing this a few days after posting this and so far everything it's working like it should. No problems and no more whistling.
@@ThePhatdoug16 happy to hear it work out well for you. I am simply trying to create more airflow to my system as I don't have returns in every room just the one larger return in the hallway 2x2.
@@spersaud424 I'd say go for it. I also have a Carbon monoxide detector in my laundry room for save measures.
You didn't put any backer wood to screw into?
Thank you for your comment. I used plastic drywall anchors for this project, but backer wood would have worked also.
is that a condensate pump inside the cold air return?
Yes it is
your return vent is to go into the furnace.. not the furnace room..efficiency is to have 3 of those.. into return air duct for a home of 2500 sq ft..
I need to replace mine too to allow more air.
Hope your project goes well!👍
@@DIYProjectsByDave HVAC guy will seal my return air box when he installs my new HVAC system. I will buy a new t-bar grill and replace it myself as the guy will charge $100 for a new grill lol.
Having the return box sealed is great. Yeah installing new bar style vents throughout on all the vents including the return will also help the efficiency and are easy to install your self. Thank you for watching!
Would doing this reduce the noise level at the vents?
This helps with better air flow but probably would not change the noise level.
I don't get it. Where's the ducing? Is this vent going anywhere? Also, unless the venting restricts the positioning, the grill could have been centred on the wall for aesthetics.
Thank you for watching. It is hard to show on the video but they furnace is located on the other side of that wall. It is on a plaform and the open space under that platform is being used as the cold air plenum. This vent lets more cold air into that open space.
Yes I could have centered it on the wall, but I thought it looked better being evenly spaced with the original one around the corner. You can move it to where you think looks best
@@DIYProjectsByDave I would've glued some mesh inside the vent for bugs
Why does your return not have a filter?
The filter is on the furnace which is behind the wall.
Good question. Maybe its in the bottom of the furnace. WOuld have been nice if he answered
This is what I was just wondering but that makes sense. I have a similar set up but in between 2 rooms instead of being in the corner. Tempted to add a new return in each bedroom
Why aren't there any filters here?
The filter is in the bottom of the AC unit. I would have still put filtered covers in... in fact that is my project for today.
No filter?
Filter is located at another location.
If the hot air is at the top, shouldn’t the vents be placed at the top?
That's a great question. Well in our case, that's how the house was built. There was one already on the bottom, so when we added this additional one, we match it to the other side. Thank you!
Do you think it’s enough to trim the bottom of the doors , they 3 are within 4’ of the main ac Unit in hallway. New carpet seems to have closed that gap ? Ty
OK, your opening 30” x 10” is rated for 2200 CFM of air flow at 0.1 friction rate, which is enough for a 5 Ton system or 120,000 BTU furnace. What maters most, is the size of your filter, that’s where the restriction is. What a waste of time and energy, misguided effort.
So is the key a low restriction filter?
samlol23 Multiple returns. 300 sq inches of minimum total return filter grill area per Ton of system capacity. 5 Ton system requires 1500 sq inches of filter filter grill area.
If you want to read in to it, you will find it in the Title 24 compliance criteria, Table 150.0-D That is if you have any inclination to do the job rite.
Josef Brunclik -thanks.
Is it ok to leave the closet door open and don't put those grills
It depends on where the furnace is located and how air flows into the unit. For example, ours wouldn't work even if we leave the door open because the vent needs to be in the bottom.
It's located on top of the water heater, ten inches separate.....in a closet close to the kitchen. It has acordion doors with vents
This not not a return. Change the description so you don't waste more people's time.
You put in a vent not a return
I completely did not understand this video and the purpose. 🤦♀️
The purpose of the return air duct vent is to promote better air flow. With proper air flow, the furnace would be working much more efficiently and that in turns save energy. Thank you for your comment!
noise barrier, air filer - not a case! Who cares!
