CAPTIVE AIRE MAKE-UP AIR UNIT REPAIR

[@jakedouglas5650]

So I'm 4 years in as a commercial tech, and videos like these do nothing but help guys with great tips. Appreciate it 🤟

[@Neckky]

Loved the B roll at the end!

[@HVACRVIDEOS]

Thanks bud I'm gonna try and add that more often

[@crforfreedom7407]

@@HVACRVIDEOS Yeah! Well done Chris, never realized how beautiful that area was. It's stunning! Nice job on the repair! Way to make it look easy!!

[@mickmclovin3020]

Love the driving scene and great music you put to it... !!

[@RayRay-nb7tn]

I have seen worse filters on a mua unit, to the point it was just flake dust when I pulled it out. Crumbled...what a mess. Good video on the prayer, timing, and what to look for on those units. Thanks man.HVAC ON!!

[@CHOMAHOMA]

Thank you for your videos again. They always help and I can't tell you how much I have learned since I started watching your videos. Keep it up. I will Keep watching.

[@1TrueDenesha]

Great Video! Covered everything nicely! Having a positive attitude on the job means you love what you do!

[@hvacsandiego]

I haven’t worked on this type of equipment with heat and cool MAU very interesting on mau that don’t require water and gas kept dropping videos great method of teaching .

[@joevinski1]

So amazing to see what other areas of the country work on , down here in Florida we do everything we can to get humidity out vs adding it in and almost no one uses gas down here for anything it’s all heat pumps and heat strips and great video too brother

[@HVACRVIDEOS]

Thanks bud, yeah it's very rare if our relative humidity is above 25%

[@joevinski1]

Wow it’s very rare ours is under 50 lol it’s so crazy that this country can be so different lol thanks for the reply brother

[@palamidi13]

Nice idea to add the route with the car in your video!

[@frontiermarvin71]

Extremely nice video ! I did not have a chance to work on a unit like that when I lived in Los Angeles !! Nice to see home on a video !! Love yours videos ! Thank you

[@xboxmaster555]

Honestly Chris (I think that’s your name sorry if I’m wrong) you deserve more subs everyone of your videos are so informational, you explain things well you least try to show/explain what you’re doing in a way that people like myself who don’t know shit actually sorta understand what you’re doing, the fact also that at the end of the video you do a recap of what the problem was and how you fixed it and explaining it in a way that really anyone with a brain can sorta get But anyways keep up the good work man Greetings from Vancouver bc

[@grashoprsmith]

I agree with this

[@christianybarra1116]

[@Jeepjones85]

That is a neat setup, I’ve worked on some direct fire equipment but they didn’t have an evaporative cooler

[@username9969]

Do i understand? No Am i entertained? Yes Subbed Edit: thanks for the heart🔥

[@DJSubAir]

Thanks Chris for the followup video 😁

[@scrambler350]

Very cool and very detailed, we don't have units like this down on the coast here in Texas.

[@gnasty30]

Your videos are amazing thank you!!!

[@HVACRVIDEOS]

Thanks for watching!

[@paulchristian8271]

I’ve never seen that particular modulating gas amplifier with the potentiometer built in. I like watching your videos to see what’s out there that I haven’t seen.

[@bradwilmot5066]

I've never dealt with a MUA like this... It looks like the burner flame is directly in the air stream... what happens to the CO and other combustion products?

[@engineer1793]

Nice Chris

[@Alex-yk6he]

Good stuff!! Great attention to details.

[@HVACRVIDEOS]

Thanks bud

[@jesussantos9192]

[@southsidecontrolsupplyco.3668]

I work on three of this units we are going to add are own cooling down stream of discharge and control with a t775 none Of the ones I work have coiling. But will be adding cooling to them

[@calebburns4346]

Are there any regulations concerning legionella with the evaporative make up air systems? I do facility maintenance in healthcare AMD they are all over us about legionella just in the last year. Not just for cooling towers, which historically is what they focused on, but for all potable water systems as well. The reason i ask is wouldn't introducing misted water be a potential hazard no different than a cooling tower?

[@sparkydave2783]

anonymous I’m not about US regulations, but for sure such an evaporative cooler is a credible legionella hazard. Water 20-40*C, organic materials for nutrients (rust, dust), potential for stagnation and an aerosol effect. That’s why one should have a proper risk assessment and management system in place.

[@calebburns4346]

@@sparkydave2783 exactly right. Those were my thoughts too that's why i was curious if the regulations have caught up with them.

[@HVACRDUDE]

Nice one bro bro! 💪👍🤙

[@1984juant]

Nice music at the end.

[@jorzer18]

Great video but turn your finished it with a NorCal Dave sequence!😃 Awesome

[@PracticalCat]

Just curious but how are direct fired gas heaters installed safely? What I mean is how are these beasts installed in a way that they don't pose a risk of raising the co levels in the building? I was at a shopping complex a couple years back where they had vertical mounted directly fired duct furnaces which used the fan from the large evap cooler on the roof. When I walked in the place (large warehouse) it smelled fumey. I was wondering how people weren't getting poisoned. I came to the conclusion that large warehouses with exhaust fan's are ok to use them because there is enough ventilation. Still not sure if I would like to work in a building all winter with them breathing in that fumey air but what do I know haha.

nice repair

[@memyselfandifarmer]

They're don't make belts like they used to, they don't last. Belt tip- measure the distance between both shafts centers, motor and blower, example 20 inches, 20/64", 5/16" deflection in the middle of the belt +-.

[@robertpeters9438]

Wouldn't a sediment filter help prevent screen plugging in the nozzle syrainers?

[@EnderMalcolm]

Wouldn't the open flame introduce carbon monoxide into the building? Or is there another heat exchanger?

[@HVACRVIDEOS]

Yes it can, systems like this have to be carefully designed and interlocked with the exhaust fans.... not my favorite setup for sure but it wasn't my design

[@Georges3DPrinters]

Highly recommend a set of left hand drill bits like the $15 left hand drill bit and extractor set

[@douro20]

Gotta love working with R718... Any idea how well CLR will work on evap misters?

[@HVACRVIDEOS]

I imagine it would work fine but be careful of the fumes blowing down in the building

[@HVACRVIDEOS]

I am gonna talk about your question on my livestream tonight, I will be going live on KZbin this evening 12/23/19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from emails, KZbin comments and the live chat, come check it out if you can kzbin.info/www/bejne/gWTMeGinlLaSZrc

[@steveblake8766]

Sweet # 7 Thumbs Up! Keep up the great videos

[@iangodshall5562]

Do you ever check gas pressures bc I have never seen it and even though you don't live where there is a lot of heat usage I would imagine you still cover your tail and examine gas pressure bc if not and like I said I've never seen you do it and I've watched almost all of your videos and it just is astonishing

[@iangodshall5562]

Love your videos dude wish I lived on the west coast and could learn directly from you but your videos are inspirational and I get as much as I can frome each one

How does mountain climate affect maintenance and care for hvac systems?

[@JuanTodoli]

For those of us who live in wet areas evaporative coolers are a rarity. How regularly must be changed a masive cardboard filter like this? Because the deterioration must be surely fast.

[@mrfrenzy.]

Did the water valve get damaged due to freezing?

[@HVACRVIDEOS]

Yeah it did

[@fitybux4664]

2:38 How do I get all this fancy outdoor air / humidified air for my home? ahahahaha. I guess just rip out existing stuff and put in nice stuff.

[@dandfgarage986]

Is the motor in that unit new

[@srrobinson07]

Can someone explain to me why these are allowed to blow combustion gas right into the building? Is it a matter of volume of air(including any CO) this unit provides vs all the other RTUs outside air/return air it mixes with just makes it inconsequential?

[@SuperUPLIFTER]

Where did you order the pad from?

[@leifhoganson4554]

Did you use matched belts?

[@HVACRVIDEOS]

Yeah

[@roylwchez]

s, Im not an hvac guy, can you explain what a make up air unit is and does.

[@HVACRVIDEOS]

Sure ... think of it this way say you take a paper bag and place it over your mouth, if you inhale the bag will collapse. But if you cut the perfect size hole in the bottom of the bag , when you inhale the air will pass right thru the hole and the bag wont collapse... So we use exhaust fans to pull the unwanted air out of a commercial kitchen because it is very smokey, and we need to bring air back into the building to make-up for what the exhaust fans are pulling out of the building. Hence why we call it a makeup air unit..... there is a term we use called air balance and that is the perfect equilibrium of exhausted air and makeup air. So typically when we perform and air balance on a restaurant we want the building to be in a slightly positive air pressure so that we dont pull unconditioned air into the building..... does that make sense?

[@roylwchez]

Yes totally does thanks for responding

[@texture6]

On the temperature control, what’s the minimum and maximum BTU.

[@HVACRVIDEOS]

The minimum and maximum btu out put would be set by the high and low fire settings on the modulating gas valve. And I do not know what those are set for you would need to do that by reading the manual and testing the gas pressure.

[@texture6]

Thanks 👍🏻

[@harrydickson4575]

👍👍👍

[@joevinski1]

One question what are those cell deck pads made of ?

[@HVACRVIDEOS]

Paper/cardboard is what it I think they are made of

[@joevinski1]

That’s what I was thinking , but didn’t seem to make sense figure that would grow mold or degrade rather quickly man absolutely fascinatinghow different then equipment is thanks again brother for the reply good luck out there

[@articairrefrigeration9142]

That music sounds like the same as my roku player

[@gaunerchen1729]

So does direct fired mean, that all the fumes get into the make-up Air?

[@HVACRVIDEOS]

Yes it does so it's very important that the exhaust fans be interlocked with the MUA unit

Those water valves fail open all the time. They can't handle even a modest incoming pressure for long.
