Balanced Air Flow TIps

[@brettbarager9101]

Glad you highlighted using aluminum tape rather than "duct" tape! Huge difference. I took the time to seal all seams throughout the whole system. Much better. Amazing how such a small thing can make such a big difference. I also insulated all of my plenums and runs so that heat or cooling does not radiate into my unfinished basement. I agree with the other poster about removing the music (or send it more to the background.

[@JoeW-f8i]

This is the best tutorial I've seen. Thanks Dave!

[@tsnstt]

The intro was an overkill but the tutorial made up for it. Thank you sir and have it a thumbs up! Great vid

[@johnnyjj2009]

That was the best part 😂😂

[@76TomD]

The intro scared the crap outta me!

[@ulisespico8219]

Super useful tips! The music is a little distracting while you’re talking, hope it’s okay to leave that feedback!

[@gidagorfen8947]

No issue hearing Dave talk with the music in the background. Good tips to start with! I've got one large room not getting the strong furnace airflow for cooling I want, so this was a good start. Thanks Dave!

[@rudolfrojas]

Very useful tips and effective presentation, i will try some on my own place that is quite inefficiently constructed.

[@andremedallion3378]

hay Dave!!! great tips and great great intro. dude you are dancing to the beat in a stop motion. classic old school gumby style. good vid man!!

[@SergeiVasilyeu]

Great tutorial!!! Thank you brother. Going to do the inspection today. Be well.

[@EarthtonesCymbals]

Thanks Dave. Best wishes.

[@maayongaga729]

Very informative...you're the only one that make sense.

[@flamefurnace]

This video is helpful. Great tips, Mars!

[@WoundedEgo]

Mars is the best HVAC teacher out there that I've seen.

First check before sealing duct-work, is to determine if the blower is delivering proper airflow. The simplest check is taking a total external static pressure reading and comparing it to the manufactures fan curve chart. If the duct system is undersized, and that's often the case, then sealing the duct-work makes matters worse.Undersized duct-work= low airflow, sealing undersized duct-work= making duct-work smaller=lowering airflow=more system issues.

[@sunnyd6019]

What are your thoughts on using the stud space for R/A? My house has this and I am not thrilled with idea of air coming from leaks in the studs, any holes will allow dirty air from maybe attic or such which is not great. Is it possible to use a liner inside the stud like ductboard or something to allow for better sealing to eliminate bad air/dirt Thanks!

[@MahdiBanners]

Please next time don't add music so we can hear what he is saying

[@jeevesso]

Agreed. Was perfect until the music obliterated his voice. Or keep the music quieter.

[@howardtoob]

I think maybe the cigarettes did that :)

[@oscargoldman85]

MahdiBanners I put on subtitles so I could get every word, but after about a minute, little graphical musical notes started drifting past and covering the words... Life is weird.

[@san1eong]

Why everybody has to screw a good educational video with stupid music that distract your attention? Nonsense.

[@michaelcollins735]

I thought the music was perfect.

[@Lockersss]

Ok, my only question is, when did John Kerry get into the HVAC business?

[@Fontari]

That was funny! I thought the same thing except Kerry isn't that eloquent.

Hi. I have a 110,000 btu oil furnace with a .85 hp blower. Originally all the intake air was supplied at the blower on the basement floor were there was a 14" by 20" opening for the filter. The furnace had no return duct at all. I had work done by a professional and a 8" x 18" duct was added to extend across the basement and two returns were added to the first floor. The two returns grilles about 6 by 12 inch in size are coming from 7" oval duct off of the larger 8" x 18" duct. My question is: Isn't this going to seriously restrict the return air volume to the furnace and also effect efficiency? I read that 7" duct has a cfm of 150, so total with the two returns is just 300 cfm for the furnace

[@lvvry1855]

I have a finished basement apartment. Can I redirect the cold air INTO the return system before the filter in the furnace?

[@HobbyOrganist]

I have a really hard to duct house, with basement ceilings only about 6' to 6'2" high, and being of a cross tee design, so the floor joists run in opposite directions. I did the best I could but one room is real warm in winter and the others are chillier, the real warm room has a return in it, only one of the others has a return, maybe I need to figure out how to add returns to the other rooms.

[@1990pommie]

great delivery.

[@Barnabas45]

My thermostat is located in the furthest (away from the furnace) room in the house, It gets the least amount of air flow and the central air is constantly ON because the room takes forever to cool?, Should I close off other rooms to increase the air flow?

[@chuch52]

I have one return vent on the upper floor of my house that has no suction what is causing this and how do I fix it?

[@raysrcsandtech]

Great video, got some foil tape and went all over the basement

[@eipekili316]

Great advice from the Janitor from Scrubs!

[@bekawzofhim]

Given your choice of a new Ruud Or Goodman heat pump which would you say is the better system overall?

*Sir....i usually don't thumbs down videos but you EARNED this one. What possible reason did you add the Revenge of the Needs type music for? Just why?*

[@lucasmiller7185]

Revenge of the needs?

[@hollywood2108]

I have new duct work I’m not getting any airflow in my upstairs bedroom can you give me a tip

[@defiantlion231]

Too long of a run with too many bends. Never pay in full until you are completely satisfied your getting your money's worth.

[@Dilllonm]

To any ac or hvac guys out there , I recently got my ac blower motor changed and this new variable speed blower Blows pretty slow compared to the last one but my house still cooled , I was wondering is it gonna be more efficient or not as good ? For comparison of the old one blew at speed 7/10 the new one blows at 3/10 ( how hard the air comes out all vents )

[@LubaLuba1]

Could increase airflow of cold air in other rooms by closing vents from rooms I don't care to cool. Because my central air system is on continuesly.

[@andyyy6307]

Is this only for single zone HVAC?

[@KB4QAA]

This really did not address 'balancing air flow" at all. It covered unblocking vents, checking for airflow into returns and sealing system leaks.

[@julianbrodie3994]

Pelican1984 k

[@jessepierce9833]

If you address the possible leaks in the duct work, the balancing should follow. It becomes unbalanced when the system has leaks throughout.

[@timholla7014]

0:50 why did the music started playing

[@nurgul4497]

Thanks but is not working

[@billro6665]

You did not cover balancing system at all. Why

[@David-kf8fr]

thank you for the tip

[@markeez2373]

I was fine till the music started then I couldn't hear the guy.

[@thomash.l.9382]

how did a commercial from the early 90's end up on KZbin

[@dogsareawomansbestfriend]

With the furnace on, the air return, one on top and one on the bottom, don't even suck in the tissue!

[@INTERNA9]

THANX

[@clairvoyantbren]

I would love to hear what you saying, but the music was distracting and loud.

[@MarcusFryTheQualityGuy]

Dave is so cool!

[@criticalreasoning2129]

Duh, code violation of CSST passing into furnace. This is against code because the all furnaces have some normal violation movement and the CSST can easily flex down to be cut by the moving sharp edges of sheet metal. Only Black Iron Pipe should pass through the walls of the furnace cabinet.

[@mdv5845]

Not a good video. He didn't address the closing of the doors to all the rooms to make the system more efficient. Do they have a 1 inch clearance between the bottom of the doors and the floor surface when closed? If not then the system is unbalanced.

[@defiantlion231]

What about if the supply vents are on the ceilings & not 1inch on the floor. There are going to be various set ups for a/c & heating units. So your 1 incher is cancelled out of the equation here!

[@mdv5845]

@@defiantlion231 If the return vents and supply vents are in the ceiling then that system is bad. Why? Because the supply air goes straight to the return vent and does not heat or cool the room efficiently. Whomever invented that type of a 'air conditioning' system is an idiot! Question for ya. What do the letters in the acronym HVAC stand for?

[@tstatech]

Call a contractor that specifically states that they deal with air distribution problems.

[@deiadraper512]

I agree the music on these videos are too loud stop with the music we're not listening for the music we're listening for what you're trying to say

[@freewoodencrosses]

The 25 second intro was too long. I agree , that most evaporator coils are hard to get to and this is probably by design so you can call those HVAC people back and pay them lots of money to do nothing as they do very little cleaning (maybe they spray some solvents on the coils).

[@acoustic4037]

Your effort is appreciated but no sense sealing floor joists. They're not code. Redo the duct right.

[@bootyman234]

Oh, I also want to say that this was an outstanding segment. I learned a truck load! cheers!

[@angelogoreham4155]

They actually have a device that looks like A balloon that measures the amount of cfms that is coming out of the vent so this guy isn’t telling you anything to do with balancing the system properly.

[@kijijiallin]

dudes voices is on point

[@themothershipp]

Good informative video but barely talked about balancing or balanced airflow tips. More about checking for leaks.

[@tochase0141]

The flex pipe inside the furnace is against code!

[@palillo2006]

Not really air balancing but rather making the system more efficient.

[@yimmeistaryimmeistar7239]

Music destroys what little imfo is available

[@WindedDragonn]

I feel like people how can't hear him over the music have selective hearing and anger towards music.

[@grebbx]

huh? nice audio mix

[@abdorakeebnaji1527]

Music music music that's all i hear from this video !!!!

[@mcanally5940]

Nice voice

[@parkrow777]

cut the music

[@PJMDValley]

I have never heard the term "pucker" when it comes to duct work.

[@ultrafaga1947]

Really???

[@suziemley]

good content but the music is very distracting and overpowers your voice.

[@grassthief1280]

Damn whats with the music cant here anything

[@aprilforslin2058]

the back ground music is distracting from being able to listen to your voice

[@cookytrix]

6 minutes wasted

That music ruin the video!!

Why tf is this in my recommend

[@matutealmanzar]

Can't take that music

[@pexto8003]

He doesnt even know the difference between a plenum and trunk duct. He is not a sheetmetal guy otherwise known as a Tin-knocker.

[@theboydyke]

Music playing over talking is crap

nothing really new, background music is annoying !!

[@larrymoongoldski2638]

Eliminate the music in the back ground, very annoying and highly unnecessary. Facts not fluff informs.

[@FM-nk1zh]

Jesus crist! The dumb music over speaking. How ridiculous 🙄

[@gmess38]

If this helps you then you know absolutely nothing. If you are a DIY with a basic working knowledge of you HVAC then this video provides virtually nothing to help you balance your system.

[@John-ny2cq]

George Messier why so negative? People are at many levels of knowledge and I’m a handy guy around the house but found lots of good tips to get me to the next level. Good grief, the internet is not one size fits all. That’s what makes videos like this one or the one you will make all so great.
