yeah, that or run long returns back to near the air handler. likely it was designed for engineered flooring and the thick carpet/padding choked it off far too much
Surprised the carpet isn't dirtier by the door. Normally there will be a heavy dirt line under the door because the carpeting is filtering the room air as it exits towards the return. If I remember right Lennox even had a bulletin out about it back in the late 90's early 2000's. Good tip.
bill j I though the same but found out these tenants have only been here for just over a month so I'm sure the carpets were steam cleaned. Thanks for watching Bill
now, try explaining that to folks with hot water/steam heat. it super duper doesn't register with them :)) furthermore, give them a bid or $3500 adding zone valves and thermostats per 2nd floor room (six of them) or thermostat per rad, but that has downfall of thermostat calling and rad thermostats all off and boiler short cycling/wasting fuel, due to no thermal load/output! >_
You can also add a retrofit above the door return air pass-through. Example: A Tamarack Technologies TTi-RAPR12.4 which is 12" x 4" and has a honeycomb mesh to reduce sound transmission.
noise transfer is an issue with above door grilles, better off with other solutions/longer duct runs or braveness of trying to use "interior wall cavity" for return. one vent near ceiling and other down low opposite side of wall, it requires open wall, which many times may be insulated now days! easy enough to drill a couple small holes with long twist bit, you'll know if you hit insulation it will wad up on the bit
lol @ polishtheturd mickelson . I fall in the over-engineering category, but also the type of "arsehatter" that tries to call foobar and keep all the junk/garbagey/chinesium on the market sane! why have all of it be pure junk that makes everyone look bad? even the best of best installers/technicians/workers/masters/super-techs look like bumbling idiots due to the garbage pushed out now days :(
I love when u tell them the easy fix just keep the door open their mouth drops like it's the end of the world that they just need to keep the doors open lol
I know this is an old video but it just started after another video I was watching. We are constantly tell our kids to keep their doors open. Our one kid gets frozen then ends up closing the vent instead of opening his door while the other is sweating with his door closed. I’m thinking of adding some sensors in each room.
Adding sensors to the room will only create a different issue. You can shave the bottom of the door about 2". You can add a louvered grille to the door, or add a pass through grille above the door frame. Each of these homeowcan do abd it will help the room breathe. That said my professional recommendation would be to have a contractor add a small return to the rooms.
I notice with no returns in the bedroom and teen's having tv, computer and some kind of gaming. The room Wil be hotter due to the electronics emitting heat. It's crucial to have a return in the bedroom.
one cannot remove humidity with out exchanging air, even if it's exchanged in a circle (dehumidifier). so technically air conditioning is beyond just dehumidifying. so neither of you are wrong! it require air in and air out in as balanced a flow as possible for optimal climate control =p

I enjoy your tech tip videos. Keep them coming.
+Harry Dejesus Awesome! Thank you for watching!
You are a really good tech. You know your stuff.
Sculpin Thanks but I'm just an average tech learning as I go.
Excellent
Awesome demonstration / find. I haven't had to do it a ton, but I like ducted jumper's (ceiling to ceiling) as it keeps privacy and noise down a bit.
Michael Housh Thanks Michael!
Absolutely! I completely forgot to mention the pass through option.
yeah, that or run long returns back to near the air handler. likely it was designed for engineered flooring and the thick carpet/padding choked it off far too much
WOW! That's a good find. I'll be sure to look for that in the future! Great Vid!
Blue Collar Thank you! Im glad it helped.

Thanks for watching Bill
smokers/non-smokers make a huge difference in that case!
Excellent tip
I have explained this to a thousand customers. Most of them act like they understand, but as soon as you leave they shut the door.
Family West All we can do is try and educate them the best we can.

Great info. Top shelf as always Brother.
Keith Howard Thanks for all the support Keith!
Great tip Brad
Great tip
Great video 😀
Great video and information thanks
Something we do at my work is we add jump ducts to every room that way they can have the door closed
Great tip!
Air Mechanical Thanks!

RJ how do handle a fart? Do you over engineer it? Or just let it slide out?
RJParker I failed to mention the pass through option but that would absolutely work too. Thanks for watching and the info RJ!

A passive return docked from inside the room to out in the hallway is much better
I love when u tell them the easy fix just keep the door open their mouth drops like it's the end of the world that they just need to keep the doors open lol
wait until you suggest adding zone valves and thermostat per "room" on second floor to the tune of $3500 :)))
Looks like you can see dirt stains on the carpet at the baseboards from the hall being in a negative pressure.
Neil Comparetto Good eye. That is absolutely the case here but that part of the video sucked... (no pun intended) so I didn't use it.
With the air return in the hallway it would seem a simple thing to add return in each bedroom ducted into the main return or is this a poor idea??

@@HVACinSC thanks for your reply.
😎👍
So you think that shaving under the door will help?
Its far from ideal but it can help. We've seen a handful of customers do this with noticeable improvement.
Is this in wild dunes ?
Nope. Palmetto Point
probably designed for engineered flooring, vs. the carpet and padding there now, which choked off the doorway gaps ;)
+throttle bottle Doubt it. Its just a very common issue that many overlook.
I notice with no returns in the bedroom and teen's having tv, computer and some kind of gaming. The room Wil be hotter due to the electronics emitting heat. It's crucial to have a return in the bedroom.
Ron White Absolutely! In a perfect world every room should have a return.
Thanks for watching Ron.
good point, electronics/other idiot devices all put off heat :))
wow
You said "Nest unfortunately." Why is that?
Yuppers see it daily and people just can't seem to grasp the idea.
JH HVAC & Plumbing Some do, some dont. All we can do it try our best to explain/educate. Thanks for watching Justin.
air in has to equal air out, many of us know that. even with water/steam heat and central located hallway thermostat...
That's why they call it air conditioning,can't return can't supply air changes per hour.
Michael Lee Its actually called air conditioning due to the process of removing humidity. (IE conditioning the air)
one cannot remove humidity with out exchanging air, even if it's exchanged in a circle (dehumidifier). so technically air conditioning is beyond just dehumidifying.
so neither of you are wrong! it require air in and air out in as balanced a flow as possible for optimal climate control =p
doors need to be open for HVAC to work
That's the tech tip bud.. 🤣👍
Very common. Unfortunately.
