It’s economizing and mechanically cooling. Lol. It all comes down to maintenance. I don’t know if you noticed but the outside air dampers are missing the metal mesh screen to keep the bugs out.
Nice vid. One thing I never do is use a brush on the coils. Simply I am not breathing that dust. Cannot be good for you and if your using coil cleaner, no need to brush. I can see in certain circumstances, but I have never run into a situation where coil cleaner did not get the coils clean with the need to brush the coil. Enjoyed the vid.
Is that coil cleaner microchannel safe. I wouldn't think so. The refrigeration Technologies yellow cleaner is microchannel safe....I tend to only use chemicals as a last resort on microchannel. Usually it's just water only.
Dawn dish soap (diluted with water) in a foam cannon works wonders, too, if you're lugging a pressure washer to the job site. The main thing is to break up the sap, oils and bug guts that get on the coils.
Hey JMT! I watch all of your videos and I really enjoy them all. I have a few HVAC questions. I really do not know this, and I am not trying to trip you up. Why is a p-trap used on condensation waste pipes? Will the condensation waste not flow out of a straight waste line? Is there an issue with odor?
You need to have a trap with water in it to keep the unit from pulling outside air into the cabinet via the drain line. I've seen units where the trap was dry, air was being sucked in through the drain, and the cabinet filled up with condensate and started leaking out in other spots, kind of like in this video where condensate was leaking out of the side of the unit. As soon as the unit was shut off, it lost that suction vacuum, and the condensate flowed out of the drain line like it was supposed to.
You need to lock into getting some trubul vacuum hose 3/4" ID 16 cfm of vacuum per hour through the hose it will cut your vacuum time by 80% or more TruTech Tools sell them
My question for you here as you are always back at this hotel. Is there not even a basic pre planned maintenance schedule in place or is everything run to fail. I get things like fan motors etc replacing when they fail but for filters to be in the state they are.
I tell people all the time if you knew what the AC system looking like in some places you would never go in. Restaurant ice makers are the worst, I have seen some with new life forms evolving in them. The microchannel coils are crap. York use to make good units.
And they say maintenance is a scam! Keep up the good work brother 👍
I usually remove the filters out of the unit with the power off,esier and all that crap don't fly all over the coil.
Great video!
i usually check the filters and airflow before checking charge on a frozen unit, or quoting the customer an evaporator change as well.
Excellent as always no other channel comes close very comprehensive, entertaining and educational top lad's 💯💯💯👍👍👍
JMT, congrats on the 100k subs. Great video as usual.
Jmt is the man for the job
I have the same pressure washer for cleaning coils. Idk about using the turbo tip on coils without damaging them but to each there own. Great video

Nice job & nice NY skyline ... Thx
Yo who else works on these bigass rooftop units. I'm learning a ton and RUclips University is the best thing next to sliced bread
I love that view
Yo yo! Helping out algorithm! Good stuff!

ABC… airflow before charging
Great video. Thank you for sharing. Have a nice weekend
where can i get that little air gun
I’ve seen it on TikTok shop
Nice work Jumper Man.
Great job bro.t shirts t shirts..lol
i thought you union guys were a step up on service techs
Hey JMT!

Oh! Okay, now I know.
Thank you so much for answering my question!
When the janitorial staff is busy having coffee.
I saw a comment already abut the mini air Gun I’ve been looking for the air gun in Amazon I can’t find it, where you got it
weren't you just on this unit a month ago?
didn't you change filters then ?
What was the year on the dollar!?
unfortunate for sure… at least the views make up for the mess
Can imagine what the ductwork looks like on the inside lol
The pink stuff on micro channel coils? You will destroy them.
Brother, do you use social media for work, too?
What area is that in? Beautiful sites. I believe y'all all the borrows?
did you spray that crap on the evap coil previously?
You need to lock into getting some trubul vacuum hose 3/4" ID 16 cfm of vacuum per hour through the hose it will cut your vacuum time by 80% or more TruTech Tools sell them
Those people killed that unit.
Hmmm. I'll guess. Somewhere around 14th street?

Aaaaasasa my worst pet pieve, how do you not no to change filter. Filters are the lungs of ac units
Crazy that I can see your videos and be like peed on that roof , peed on that roof and peed on that roof
NBC coils...never been cleaned
York design is difficult to maintenance.
What means tatoo on Your right arm?
Best practice is to NOT use cleaner on micro channel coils
top off the circuit that's running, it's a split evaporator, they're separate circuits

😻💚💜💚
That filter…. 😣
York RTUs are dogshit in all aspects
good job partner
