Captive Aire makeup-air water leak
HTML-код
- Опубликовано: 15 окт 2024
- This was a service call on a water leak from a make-up air unit. We found that the unit's evaporative media pad was frozen solid due to a stuck water solenoid valve. I let the unit defrost fro a few days and returned and diagnosed the unit, all togather we have high airflow, a bad motor pulley, a stuck water valve and some bad metal mesh filters.

You say it blows your mind that we watch your videos, but your service calls blows our minds. If I lived out your way I would love to work with you on weekends as a part time job.
I'm a student in a HVAC school in dallas. I watch your video's some mornings while driving into class.
I really enjoy your real world situations, diagnosis and follow up analysis post completion of jobs.
I will continue to wat h your videos and thanks for sharing and not hoarding your knowledge.
Big two thumbs up !! I never encounter this unit before. I got offer from company that owns 32 restaurants from A.V. , SF, and Ventura for HVACR
maintenance. I'll find out by Monday for interview with owner. this might come handle if I visit this unit like yours. You know you're our mentor. Keep it up with your good work and share. Big thank you Chris !
I work on these units all the time in Canada. Every single one of these captive aire units with the yellow rtc solutions amplifier (temp control for the modulation gas valve) and discharge air sensor in the blower section has been faulty. They will all run too high of a discharge air temp when the heat is on due to this, as they can not properly modulate the gas valve. I have replaced the amplifier and discharge air sensor with a maxitrol 1014r and a ts114 sensor and have had no issues since on about 10 units so far. The gas valve itself is a maxitrol so it makes sense to control it with a maxitrol amplifier.
Interesting, honestly we dont use the heat but for 1 month out of the year so that is probably why we dont encounter your problem
Hey man I don't even work in your industry, I actually work on cranes haha but I just enjoy watching and listening to you do what you do. I quite appreciate the way you explain everything 👍
Thanks bud I actually had an employee leave us a few years ago to go work for Bigge crane
I believe your pressure was jumping around because you had the evap door open allowing it to suck in a lot more air than it was balanced for. Did you try measuring the pressure after closing things up?
Always great stuff. I work on a crew that repairs cafeteria equipment & refrigeration at BYU and have gotten a lot of great tips from your videos. Thanks for the time you put into making them.
Same here Geoff. We are Horeca (hotels, restaurants & cafés) + Refrigeration here and Chris helps a lot. Doesn't matter if we know about the video, it's always a pleasure to watch and listening to the methodical troubleshoting skills he has. From minute 0 to the end.
Thanks Juan
@@HVACRVIDEOS You're welcome.
I'm always impressed with the quality of your diagnosis and troubleshooting. I have no doubt it's due in large part to the time you take talking with and gleaning information from the customer. Excellent. I'll remember that. That time you invest seems to pay big dividends.... Well done!
Awesome video. I service 5 direct fire make up air units at a prison here in Missouri. They are heat only, no swamp cooler. When I started the job, not one of them would 🔥. They had a major air pressure problem due to them not running them during winter. Mold everywhere from all the steam and water in food service. The ignition module was like nothing I had ever seen. It was a board with about 6 relays plugged into it. I can't recall the maker of the ignition module. I couldn't find any information on the make up air handler itself. I ended up ordering all new relays for every unit. Bingo, we had heat! Ended up with employee of the month for saving the institution an estimated 7k in repair costs. There is a push button circuit breaker on this particular control module. Every once in a while one of them will trip. I still haven't figured out what causes it.
Worked on a 5 million btu make up air today, weather-rite. Same air flow issues. Found the dampers not in a great position, left and right side need to match. Making the pressure differential so big it would lock out. Happy hvacing!
Thanks bud mine is tiny compared to yours! :-)
It’s all the same no matter how big! (It’s for a yacht building company) there’s actually 3 of them. Interesting, it defends on how big the yacht is when it’s being painted. The boat could be the size of the building and needs less airflow. Pretty cool stuff. Wish I could make videos like you but I’m clueless on technology..
That burner looked crazy, I would like to see that thing running
I will see if I can get a video when I repair it
Looks like the flame tube out of a jet engine.
MrTurboturbine It’s in the next video (which RUclips showed me first)
Thanks you. I went on a journey watching this video. It started with DUCT BLASTER and duck leakage test science. Then I fell into RESNET and HERS Rater certification.
Usually when caught in a RUclips loop you end up with something like cat videos in the end
That's some fancy equipment there bud. Good job...
Thanks bud
Nice video. I listened to your podcast the other day on HVAC school, very informative
The temperature control podcast?
HVACR VIDEOS yes that one. Thanks for sharing
I used to work on the north coast of Alaska- we had some 5 million btu direct fired heaters - they were trashed when I got there but I resurrected them. I was surprised to find parts still available for them - even burners. They had 2 inch fuel gas lines coming to them... they did keep things warm when it was -50 outside. There wasn't much makeup air needed in the winter lol
Another solid and through video, Thanks Chris
Thanks bud
Always through been watching you and nw Ohio HVAC. Thinking of making a career change and trying hvac out
Do it HVAC needs more techs
Been really thinking about it past few years
All your videos are great,
Thank you,
I learn a lot from your work.
Millions times thank you.👍👍👍👍👍👍👍👍👍👍👍👍😊😊😊😊😊😊
The burner may have locked out because the water pad shouldn't have frozen inside the box but definatly can on the outside, does it need heat tape added to the waterline? I myself would call Captive Air and run everything by them, there great to work with and I don't see these every day, so I need a reminder every now and again on jumping out the Maxi Troll control. You might also check your low and high fire temp rise, clean your flame rod, and punch out your burner orifices, basically run a drill bit in the hole by hand (no drill) to get any rust that may have accumulated in the orifices. If low fire is not adjusted properly it could lock out on a flame sense issue and if the high fire is too high that also could cause a high temp limit to trip and shut the burner down. The one I did a video on this summer didn't have burner doors that had Springs? that's kind of odd. But I adjusted that in the summer and we had issues with it this winter because the characteristics of the air has changed.( Heavier vs. Lighter air go figure.) Great video as always Chris👍👍 Thanks for the recommendation, I appreciate it!
The burner never actually goes on lockout (indicated by the control board with the led's) the board has lights that show the sequence
CaptiveAire is very helpful as NW said..looked like a fireye contol. Worked with these for years up to 50hp blowers..
The swamp cooler could use heat tape.. service a few in SW Ohio on top of Huge bonded warehouses by the Cincinnati International airport. A few on assembly buildings usually in paint shops.
You're the guy! Logical,analytical and reading a book!
Great great video as usual sir. I was actually wondering if you could make a video on how your company goes about doing their preventative maintenance? Procedures, dos and don’ts things like that. I think that’ll be awesome
Always interesting hearing about your work..
Thanks bud
Awesome video, I have never had the chance to work on or even see a make up air like that (not much of a demand for evap cooler here in MD). Enjoyed seeing some new. Keep up the great work.
Thanks for all your hard work,,,, kudos to you!,,
Thanks bud
Good vid Chris ... Young'ens learn from you and other's in these trades ... Enjoyable ...
Great job again
Thanks for watching bud ,I will be going live this evening 2/25/29 @ 5:PM (west coast time) on RUclips to discuss my most recent uploads, answer questions from emails received and the chat. Come on over and check it out if you can

Never seen anything like this before. Great video learned something new today!
Thanks for watching bud!
Looks like a buffalo wild wings had a control board go bad on one . Captive air support where very helpful to. Miss doing HVAC since I am disabled.you know your stuff that is for sure.
Nice repair video 👍
Doing this work all my life,and watching your vids its like a moth to the flame cant help it. Problem solving is in the blood.
Thanks bud
Never seen one in North East North Carolina. Very good video
Thanks bud
you got yourself a new subscriber! i really enjoy watching your videos :)
Wow thoss are some cool looking units. Cant wait to see next vid on these...good work
5:44 First time I've seen a customer name revealed, lol. "Marinello Schools of Beauty". Shut down in 2016. Either this was a neighboring building, or maybe a new customer buying that building. 😁 Now we know what kind of customer gets fancy humidified air.
Do to the ambient air into the mua unit you might want to suggest TAB BALANCE to the unit. You can adjust the Bolemo damper mtr to correct air inlet. Due to temperature drop it might be worth suggesting. I like those units best in industry.
I have no idea what you talking about but yet I can't get enough of your vids you seem like you would be a great teacher thanks for helping a bumblefuck out!!
Thanks bud
Yes your right your tips sharing with us help us to do perfect job
Great attention to detail man. Love it. I know where you did this job. Its like 5 minutes away from me haha. Hope they agree to the fixes.
Great Video! Keep them coming! As soon as I seen you video I clicked instantly... I know its alot of work, slowing down you Job and having to edit your videos but we appreciate it!
Thanks bud
I've serviced a bunch of those make up air in Minnesota snow gets in them and shorts out the burner control
Love your videos. ⚘
Good stuff! We don’t see many direct fire make up air units either.
Thanks Tersh
Dude, I'm not even in the business and I watch the videos, I'm a Lighting Designer for concerts lol. You have interesting videos.
Thanks bud!
Im not a hvac guy. I do enjoy your videos. What is and what does a make up air unit do?
I've never been a big fan of direct-fired MAU's. They just seem to be far too finicky at times. I've used them in warehouses and industrial applications, but usually not kitchens.
Freaking amazing work and troubleshooting. Question how long have you doing HVACR. I love watching ur videos brother u leave me speechless
Officially since 2002 but I grew up in the trade
@@HVACRVIDEOS Wow brother I envy you. I went to school for hvac In 2009 9 month course. Ive worked for 2 ac companies and the majority of my work and knowledge has been in apartment complex. I know nothing about HVAC Refrigeration all my knowledge is 5 tons and under residential I've done in 9 years over a hundred fifty installs and troubleshooted I don't know maybe 300 units. I've been wanting to further my education in the HVAC field for refrigeration commercial. I live in Jacksonville Florida so I seen some of your videos you live in California. Question are you the owner of the AC company or are you just an employee
Thanks for watching, I will be going live this evening 3/25/19 @5:PM (pacific time) on RUclips to discuss my most recent uploads come on over and check it out if you can... ruclips.net/video/Bqx-RSJsidY/видео.html
Couldn't you just build a small wall a few feet in front of the unit to stop the direct air flow, I feel like that would be one of the cheaper options.
Those side dampers for the profile plate on the burner should open in cases of high airflow by passing the Burner, it would change your discharge air temp but should still keep the burner on.
yap its been cold the last few weeks here in the desert. its been as low as 27. right now its around the mid to low 30 for night time. normal temps for this time of year.
Have some of those on Chicago running with ac drives and potentiometer for the gas valve and the ac drive that all the time affect the building pressure affecting the burners of the ovens inside the area do to the crazy wether in Chicago the occupants have to be adjusting those potentiometers causing some other issues on the productions machines
High 20's what the hell,I thought I seen Palm trees in your vids....lol......cool vid !!!!!
Yeah this is up in the high desert
The burner burns directly into the stream of air that enters the building, or has some heat exchanger? I would think it is the second. But don't see it on the video. Also would love to see the burner in action !
The burner is in the direct stream of air entering the building, so all the products of combustion enter the building so it is absolutely critical that this unit not run unless the exhaust fans are running too.
@@HVACRVIDEOS that sounds crazy! Is it usual to find that configuration?
Yeah it's pretty common for a makeup air unit, especially back east and in the midwest.
Out your van widow shows chemtrails everywhere, that's air conditioning on a global scale. Love your videos brother; Peace

Good stuff, as usual 👍
Thanks
Classic push-tab bug bombs are very very bad for cell material. Any acidic gas of any kind is going to hit that moisture and turn into acid. Cell Deck claims they're self cleaning and in the end they are... right down the drain. Cheap is the operative word tho, supposed to be thrown out regularly... like that ever happens.
Love your videos!
Thanks bud
What’s a good cheap leak detector that’s affordable?
How did having the heat on help defrost it, the burner is downstream of the Cell?
The heat was on to help the cooks stay warm while I defrosted it with the outside air. I realize I implied the heat would help defrost it but i meant the air would defrost while the heat helped the cooks stay warm
Great video
Those need to be winterized every fall that way this doesnt happen. I have seen the water distributor freeze before.
man how do you know so much? do you read the mannuals? or what is your best tip?
Yep I'm just curious so I read as much as possible
Great video 👍
Thanks bud
much appreciated good stuff thanks again
Those damn solenoid valves
Yeah what a trip huh!
What was the name of that cellveck media? I probably butchered it. I’d like to know how to properly spell so I can research
CELDEK
I hadn't realized when you said Direct Fired that it is literally a burner right in the air stream until you showed it. Interesting. So the products of combustion go in with the air. Quite an eyebrow raiser for the ignorant among us. I guess dilution is the solution to pollution! ;) Mostly just carbon dioxide and water I suppose but still seems odd. You're right in my area. I live in Mission Viejo and have friends in Hesparia and Phelan.
Yeah direct fired units have interlink switches that ensure all the exhausts are on before the mua can turn on. I actually used to live in the high desert but now I'm down in riverside
Ah, even more safety factors built in than I had imagined. I used to be a commercial electrician but never got further into the HVAC equipment than connecting power to them. ;) My brother lives in Riverside lol. Small world.
Yeah it sure is a small world
Is it possible that the springs on the damper are simply going bad? Not opwning properly and messing with the pressure, cause it seems like you were pretty damn close to your .80 in. target
Good one.
Don't you find it sketchy to working with a ring on? even if it's not metal we work with moving parts
I feel fine with the silicone ring because it will break really easy
oh interesting. I had never heard of those before
Www.qualo.com
Have you worked on anything by Governair?
No I havent
Loved it👍👍👍👍
was this recorded at the UK?
No sir I am in the U.S.
@@HVACRVIDEOS oh sorry i saw some parts of the AC that was also used at the UK
Man that ambient air gets cold
🤣 I wish that was all the colder it got here.
Were a bunch of babies here
How much does the hood in the kitchen draw out?
Soo, direct fire is carbon monoxide going into the building?
Yep, there is usually an interlock with the exhausts to make sure they're pulling air out to keep the co levels in check. More efficiency that way
I dont think so..looks like there's no contact with the flame so it's the same principle as your stove top..make up air has so much volume it doent let carbon. Monoxide levels accumulate to be a problem
weird, I've never seen a furnace like that. Normally there's a heat exchanger. But I guess with enough fresh air it's fine??
Not CO by design. But yes 100% of the flue gas is blown into the building. As said before they are usually interlocked with exhaust fans that will make sure there are enough air changes.
Also things to think about, due to the burner design and the fact that there is so much combustion air, they design them that way as to make it very unlikely to have poor combustion. Also the chances of recirculating the flue gasses into the combustion air is low because it’s pulling in the combustion air from outside.
Remember CO is a product of incomplete combustion.
Yeah apparently water, carbon dioxide and maybe nitrogen oxide are the only emissions. And with tons of fresh air going in it's probably fine.
Why not have DX cooling coil installed if outside air can get that cold to freeze water, seems like a dumb design?
it is a very dumb design, they also have humidity issues in the summer
More videos please
Lil knowledge stop it bro don't down play ur self like that ur a guru to diz hvac/r life keep up the good work I don't know you personally but ur my Batman no homo n I feel like robin lol hopefully one day I'll reach ur level
