Thank you for this video!! I'm 71 years old and your video solved my problem. One of my rooms was almost 10 degrees colder in the winter and very hot in the summer. I didn't think anything inexpensive would solve it. I hated to call a repair service and pay a fortune. Your video worked!! I had no dampers on any of my vents. I used other videos and installed four dampers and the heat and AC in each room are balanced within 1 or 2 degrees of each other. Yes, I had to crawl through my "crawlspace", but your video inspired me and convinced me this was the answer. Total cost: $29!! Thanks buddy.

Purchased: August 2023 - still works GREAT!I kzread.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

Thanks Man . I found the dampers and it was totally closed to one side of the house. Once I opened it. Every thing fixed and heat went out to all the house again. Your video is estremely helpfull

Man I have to thank you so much for this video, I thought there was something wrong with the air duct or some how kinda clogged not allowing much air. The other rooms upstairs the air was wide open and blowing strong except the master bedroom, master bathroom & closet. I tried closing other vents to redirect the air flow but nothing. I'm kinda familiar with how the ducts are run and came on KZread for instructional videos and your was the second one i saw. I was about to go to Home Depot and buy the equipment to add 2 extra vents on the master bedroom to help it cool down. I never knew about the levers until this video. After watching this I went right to my attic where the ducts are near the furnace and found the dampers, adjusting levers that was wrapped in orange string hanging down. I never know what they were until now. There are 2 giant ducts leading to smaller ducts branched out. Right at the beginning of the duct were the lever aimed in a diagonal angle upwards, I turned them completely horizontal and success, strong blowing air!! I'm so happy and thankful for this video, you saved me money 💰!!!!

Fantastically useful. I bought my funky 70s house 3 years ago in a place that has all four seasons - a brand new experience for me and my family. It has 4 levels and the airflow is a huge issue. Every winter we have roasted upstairs and worn sweaters in the lower levels. In summer, the opposite. Plus the bathroom vent blows out what seems like most of the air, leaving little left for the living room and kitchen. Trying to close that vent led to poltergeist levels of shrieking. Dreadful! I never knew about those nifty dampers until seeing this video. To my shock and delight, my retro house has them exactly where you said they'd be.

Thanks for the video. Explains clearly what many servicemen over 15 years wouldn't take the time to do. My case is a 1994 construction two story in New England with finished basement, garage under... and everything is in the walls. It's all floor registers (except the two gems in the basement) and there are two returns, both in the living room, the most central room in the house, also where the thermo is. I have two rooms diagonally opposite from the air source that are easily 10-15°F difference from the rest of the top level (minimal if any air flow) even with their d does wide open. Also a prior owner cut directly into the main branches in the basement to source two registers in the finished area down there, which is easily stealing 5° or more and a TON of airflow from the rest of the house right out of the gate. Adjusting the round registers does nothing noticeable. "Best" of all, there's only one thermostat for the 3000SF of finished space on three levels. Can baffles possibly be retrofit right at the furnace where everything branches out? Any way to permanently close off one of those basement registers (even if it means pulling sheetrock) Any ideas that don't involve tearing into other walls or floors would be appreciated.

Great help thank you im going to go find the dampers .. because all the cold stays in the basement

Great video! I had a technician come out because I wasn't getting heat in 3 bedrooms. He told me I needed to a damper installed. He said my house (built in 2006) didn't have any in the duct work.

Every homeowner should watch this video ! Or at the very least, be told about the damper controls at the trunk line ! I've been 'suffering' for 23 years in the hot master bedroom of my house -- closing other vents, fans outside my bedroom blowing in, etc -- all with minimal effect. Lately, I've been thinking about adding a power-linked booster fan, another vent, etc -- what a pain compared to this solution. Great how-to video in general, especially on adjusting the dampers w/o even breaking through the insulation.

This is very useful (even though I'm late to the party). I have a single story (ranch) with all of the duct work fairly easy to get to from a full basement with drop ceilings. None of my ductwork has the insulation around it...I'm wondering how useful it would be to try to retrofit it with insulation. The finished basement is a pretty consistent 68 degrees regardless of the temperature outside. Would you suggest going through the effort of trying to add insulation where possible? At least I have dampers to adjust. Thanks!

thanks for upload ...

This video and information is golden. I have been having major cooling issues upstairs in my home. I've tried closing off a few vents to try to balance out the air, I've turned on all of the ceiling fans upstairs but the three rooms on one side of my house will not get cool enough. I was told to get smart thermostats and sensors to help. The sensors help me see that there's really a problem. The difference in temperature is 5 degrees so I know for sure this is definitely the issue considering I feel very little airflow on all of the rooms on that side of the house. I've called out professionals and they say that I need a more efficient unit which was going to cost about $20,000 since my house was built in 2004. I will take the time to go into my attic this week to do this for that side and I'll tape up any leaks that I find. I can assure you that you're saving people a ton of money with this information.

From that trunk duct you will most likely have flexible ducts, probably around 8 inches in diameter. Where the flex duct connects to the trunk duct is where you should find the dampers. I doubt the dampers will be at the air vent.

I am a certified HVAC contractor with over a decade of experience. While I do find this video educational and informative I do believe that this video doesn’t talk about return air problems and in my opinion return air deficiency/luck of return air is the major issue with residential construction. I can safely say that ~95% of residential properties don’t have enough return air ducts and for 2 stories houses it is a case of 100% deficiency. During construction people use inside of drywall space as a return duct/pathway. Standard space between two studs can route ~100-120 CFM of air.... so, if your house has 5 ton system , your house should have 23-27 of these returns........ now, go ahead and count how many inside of drywall return your house has. You are lucky if your A/C unit gets more than 30% from what it designed to have. What does it mean?...... It means that ~50-60% of your electric bill goes to....... goes to..... utility company for nothing! So, look for a HVAC contractor that is able to do simple math and can calculate air flow correctly. You will be glad to see your electric bill after when air flow will be improved. I can help you with this issue if your house is in greater Memphis area.

I don't have the dampers in my house. Not required by code when it was built in South Florida in 1986. My problem is that I have a vent right above the air handler going into the living room that is taking all of the air and leaving none for the bedrooms. I think I am going to "damp" it by placing a section of AC filter in the vent grille, probably trying a few different filter material types to see if this makes a difference. My only thing is that I do like more air to the living areas during the day at the height of summer and more the the bedrooms at night so I may have to figure out an easily adjustable solution.

Well, very informative video but my home has NO dampers. It was built in 2002 in Florida and is 3500 sq. ft. living area. I suspect that depending on where you live and the local codes that you may, or more likely, MAY NOT, have dampers installed. I am very savvy regarding HVAC as evidenced by my videos. I can only say that I wish I had dampers, but alas I don't. The most common way of alleviating imbalances in a home is to mitigate pressure imbalances from room to room. That's done by adjusting the return air that's routed back to the HVAC unit. There are many videos showing how to do that. The usual remedy is either to add a return to a room, or rooms or add 'in door' return grills. The problems with temperature imbalances is almost always in the return side of the system and not the supply side. Once you've got the pressure return balances mitigated then you can go about using your REGISTERS as a throttling mechanism to do what Kris has done using the dampers. Almost all ceiling or floor registers have one, or sometimes more, levers that allow you to open, or close off, the register to some degree to control airflow into the room. This is the same as using a damper. It does exactly the same thing and possibly better because if you have multiple registers in one room and you have an area that's say colder than other areas of the room you can fine tune the room to your liking by using localized registers. I have lived in several places in my lifetime and this is the first time I've heard of them installed. I've lived in the following states: New York; Illinois; San Diego, California; Alameda, California; Chesapeake, Virginia; and a few places I no longer recall. Never did I have a home with dampers installed in the ductwork.

I have one room that doesn’t get good air flow I noticed that it’s ran from the trunk right next to another duct. That duct is a short run to my bedroom an the other is a longer run to another bedroom. Assuming that airs taking path of least resistance. I closed my vent a bit to get more air in the other room. I notice a difference but that room still seems a bit warm when I walk in there. My room now since I closed the vent slightly has the air blowing directly down instead of evenly across.

In terms performance, what's the difference between adjusting the dampers as oppossed to the floor/wall registers? Seems like it would effectively accomplish the same thing?

Hi Kris, great video! How would you manage a 2 story home where in winter and summer 1st floor is cold so that 2nd floor can be comfortable.

Is your house a split system? Meaning 1 unit for up and 1 unit for down? Each thermostat will maintain it's set temp but rising heat can trick the upper tstat. The biggest issue i see in balancing across different units is thermostat location. My house the upper tstat sees the rising heat and does not come on enough to warm the far most back rooms--generally tsats are near the intake but i may have to move mine to get more even temps up and down. Have a look at where your tstat is. I'm guessing it's nice and warm in that location. If your house is a single system, reverse dampening will help, but a pain to set them 2x per year--and throttling them back too car can cause excessive back pressure on the system and cause other issues. Unfortunately with a single system, balancing across floors is not an easy solution.

@@KrisKasprzak Thank you. Unfortunately, it is a single system with tstat at lower level which must be set at lower temp to keep upper level comfortable. I will explore motorized dampeners and separate tstats.

I went to my attic to check the air-leaking and I wanted to replace the entire air-ducts. I found one "triangle duct box connections" with branched out about five lines. This is too many lines mounted on one small triangle duct box. Should I separate them?

Great video thanks for posting! Question, I located my dampers, only 2 slightly off so I turned back parrallel with duct for now to see if that helps. I have a 2nd floor bedroom over a garage that gets very hot in the summer. If I closed dampers all the way on other side of house where its cool will the air be redirected to the other side to go up to 2nd floor? Looking at where and how many dampers I have they aren't labelled where they feed, how can I find this information out? Thanks in advance!

Closing other dampers will force air to the open ones. It's hard to say how much air increase you will get due to duct pressure drops etc. without seeing your duct system. However rooms above garages are very challenging to heat/cool. Unless all walls, ceiling and floors are very well insulated--which they never are, you will get higher temperature swings. How hard would it be to add an additional vent in the room above the garage? Adding vents may sound hard but if you have reasonable access, it's not too bad.

@@KrisKasprzak I'm not sure, built in 2004 and i have 4 if I include the walk in closet....feels a little cooler already . So if I semi close one on other side of house should help push some air up ?

Yes it will but you will need to give it several days for the room temperature to stabilize

@@KrisKasprzak Honestly I'm not sure, appears there is a duct in drywall in the ceiling in the garage. I have 2 returns and 4 vents total already in the room.

This is great if you have an attic access or a basement. How do I find my duct work on a house built on slap?

Do you have a forced air system? Then you will have ductwork up in the attic it may be a tight squeeze though.

I am hoping this is my issue, I have a crawl space. My daughter's room is 15° warmer than anywhere else. But in the upstairs it has two vents but it's almost cold, so I'm guessing the duct through the dead space is not covered up.

How do you insulate the cold air duct (very cold when it’s -40 outside) it’s exposed in the unfinished basement. (Making the basement cold 🥶)

Seems like an easy fix. My AC unit won't kick off once it reaches the desired temperature. Often, it struggles especially when temps go above 85 degrees. I live on the second floor in a condo so my unit is in the attic. I've been up there to look at things and I didn't find the dampers. I saw in another video that you might have to feel around for them or even make a slight tear in the duct work to get to them. I'm afraid that there won't be any dampers due to this being an old building. I'll report back with the results.

Thank you for the video! I recently experienced the same issue as the master bedroom getting much warmer than the other side of my ranch home. The HVAC guys came in today and the dampers were like the second one you shown in the video, covered underneath the insulation. Instead of adjusting a bit at a time without tearing the insulation, the guy simply used his finger and torn the insulation wrap around the damper lever and then adjusted it. So now it looks like the first one you shown. My question is, does this concern you that the insulation was torn and it may cause problem in the future (heat/cool air leak, condensation built around the damper since the vapor barrier is cut etc)? I am a bit pissed of how these HVAC people did the job and how much they didnt care about the owner's concern, and i hope to get a bit advice from you?

+MyPandaPunch I don't think having the cover torn will really hurt but I would spend a few minutes and cover the hanldes up with insulation and the wrapper (or even tape)--but only after your room temps are balanced. Most of mine are torn but covered up and I never see any condensation--and I routinely check my unit. The most important thing is to make sure there is no exposed duct work. Heat loss is not the issue, condensation as you point out is.

Thanks Kris. Didn't expect such a quick reply! I am a first time home owner and still have many things to learn. It's a bit hard for me to routinely check on all ducts as all my ducts are in one side of my attic with whole bunch of blow-in insulation, and but i will keep an eye on the two damper they torn and adjusted (they can be accessed relevantly easily). I am hesitant to tape it up because as you mentioned, they might needs to be re-adjusted again in the summer. Have you pay some pro to do seasonal tune up of your HVAC system and stuff? I called a local company for a quote and they told me balancing air is not included in their tune-up service. I've no idea how much it could cost me if one day i decide to call someone to do a complete check of all duct work, as i honestly don't trust much about the builder's workmanship.
