- The day begins with a stark realization-1 unit on the first floor is down, disrupted by a manual reset high limit switch trip. Witness the troubleshooting process as we reset the switch, coaxing the unit back to life. Little did we know that this was just the beginning of a day filled with HVAC mysteries.
The saga continues as we discover that all units on the second floor are down for an unknown reason. Dive into the perplexing journey of identifying the root cause. After a strategic power cycle, a moment of triumph ensues as all but 1 unit springs back to life. The lone non-compliant unit, as it turns out, shares the same ailment as the ground floor unit-a loose blower wheel.
Experience the meticulous process of tightening the blower wheel, breathing life back into the struggling unit. The race against time intensifies as we prepare for the impending winter storm, ensuring that all HVAC systems are operational and ready to combat the elements.
As the day unfolds, we shift gears to address the final challenges-2 boilers in need of a gas valve change and a new float vent. Join me in the intricate process of enhancing the performance of these vital components, ensuring their reliability in the face of the approaching winter storm.
Through this storytelling, my aim is to provide viewers with a firsthand glimpse into the unpredictable nature of HVAC work. Whether you're a seasoned professional seeking relatable experiences or an enthusiast eager to understand the intricacies of the field, this video promises an engaging and educational journey through the challenges of "HVAC Nightmare: Units Crash Before Winter Storm."

You run with a backpack but NO DRILL!!
On your 20 ton York RTUs, the blower motors need to be greased with blue grease, just a couple pumps on each grease connection annually. For the blower pulley you adjusted to tightened, don't do that unless the amp draw is fine. It widens the width of the blower pulley making it closer to the blower wheels pulley width, causing it to do more work (move more air) increasing amps. Next time, adjust from the plate the motor is mounted to. Other than that, they should maintain their units more to avoid the limit issues from dirty filters and small issues like this. I know the struggle, some customers just want band-aid fixes and get annoyed when the equipment breaks down. You're doing great!
I don't know why but its so entertaining to watch someone else struggle with this work i did for 45 years 🤣🤣🤣🤣
The video, the music, the humor and the drama all rock! Doing a slide on that ice roof? Priceless. We love your videos! All the best!
If you see a high limit trip, take a temp rise. That would be the quickest and easiest way to determine an airflow issue
did you check the current draw on that blower motor after you tightened the pulley? You can't be sure that you had it back like it was originally. You may get a callback if the motor burns out from being loaded too heavy.
sorry have to point this out, you don't close or open the pulley to tighten the belt, you are changing the speed of the blower and (possibly) changing the air balance of the building, you should be moving the motor to tighten up the belt
Yeah somebody seriously failed this dude
I can't believe this comment is this far down and that there are so many "good jobs" above it. This dude seems like a really nice dude but damn, he needs an experienced Jman to train him. @@cameronblades2394
Exactly. Could cause the motor to over amp as well.
I would generally agree but since the keyway had fallen out there is a good chance its probably where it was supposed to be now, although an amp draw should have been done after, also the driven pulleys split taper bushing was also loose and never got tightened at least not shown in the video.
@@Byron88 The keyway fell out. Maybe the sheave is in its original position. Maybe it’s not. Should check amp draw.
Set your pulley to motor amps and check temperature rise. You’re doing great, but slow it down a bit. I’ve been in the same position that you’re in and remember to take it slow and if you’re not checking you’re guessing. Keep up the good work and videos
I seriously love your channel. I'm 44 and starting a new career in the HVAC industry from industrial sales after some bad life choices. Your Informative and I feel your duh and omg moments.
Hey cuz - great channel so happy to see you doing well
It’s pretty obvious the first unit you looked at was low gas pressure. The flame should never be going back the far
Good vid. Experience + Logical Problem Solving skills = a pretty much guaranteed fix!
The way you use that teflon tape tells me you’re a rookie fr 😂😂
Adjusting the drive pulley in will increase the motor speed and amp draw so you could cause some issues by adjusting your belt tension that way. Loose set screws from all manufacturers are becoming more common these days.
@theapprenticesurvivaIguide I'm happy to discuss anytime. I'm always down to chat with other techs in the field.
Good old York! We've had multiple York RTGP Units come from the factory with the pulleys not tight, and eventually the whole pulley comes off. Quality control just isn't what it used to be! Keep up the great work brother!
Experienced the same thing on a rooftop sweep with all new York units pulleys came loose
Yes. We've had thousands of dollars in damage to brand new installs of Yorks where the shafts along with pulleys needing to be replaced from coming loose. They must have a toddler that tightens down all the set screws.
I had that happen at a location with a bunch. I retightened them and they came loose again. Ended up damaging key way in pulley. When I called them to order a new one, they had switched to a tapered bushing design. I think the torque from the huge motors were loosening the set screws. Bad design on their part
They make a little 12v impact it’s a helluva tool. My hands would be cold if I was removing panels by hand. Also gloves are pretty great
Nice work really enjoy your videos
Really enjoying your videos - great production, great editing, great music. I had a hydronic system in my last house and wish I had it again now. Very helpful information about how to maintain them for when I build my next house with either hydronic or steam heat system for under floor. I'm in Asheville, North Carolina. Hit me up if you're ever visiting this area. I owe you several high quality craft beers that Asheville is famous for.
Love this channel ❤
I watch your vids while im running Hvac service calls on Arkansas, keep up the good work!
💪🏼Good stuff
Had a hot air furnace that would intermittently die. Took 2 years before the gas valve finally failed in a way that wasn't intermittent. I suspect the gas valve had a defect that would only prevent it from working in certain temperatures and only intermittently. Unfortunately the temperature range was when it was really cold out ! Replaced the honeywell gas valve and hasn't had any problems in almost a decade. You almost need some kind of data logger that you could hookup against the 24v contacts and record the history so you could see what is happening. Now that the cost of electronics is pretty minimal I am surprised there isn't built in data logging for all sensors - maybe the newer stuff has it. The LCD display telling you the issues with the roof units was pretty interesting - beats having to count flashes !
Where are your gloves dude? It's cold outside ; )
numnuts goes on roof top jobs no wintr gear unreal he will learn lol
I always clean the flame sensors, and remove and clean the burners.
Great video. I am curious about the gas valve. Do u usually carry different kinds of gas valves in your truck? or only certain types. If u dont mind sharing.
Key for the key way
York 6 flash is almost, always a loose belt or cracked belt
For a whole minute I was saying "PLEASE don't touch the pulley" to myself... The 4 screws on the motor mount might be loose as all hell and now a new problem is introduced and the old one will also come back
Tightening the pulley makes it bigger in belt diameter, the motor will spin at a higher torque and amps, the blower will spin at higher speed and the air balance of the building will be out.
nice job rookie....your good... i love my klein multi bit nut driver-you a union guy?tech tip you may like-get those mamba gloves united sells and put hot hands in them-works awesome and you can still do wiring work-double the gloves up and they last all day
"Gotta act fast"
Home Depot said otherwise.
If you suspected a gas problem, why didn’t you check the pressure? Also, you don’t adjust the belt tension with the pulley. The pulley adjusts speed. Tension is adjusted with the slide bracket on the motor.
Oh man.. you should get yourself some of those milwaukee insulated gloves for outside winter stuff.. they will really save your hide.. literally.
Roof top units in Winter ❄❄❄ are so much fun ! We have 14 on our Church ⛪
I wouldnt reset power before you start troubleshooting. If anything is in error you may reset it, you'll get a call back when the error happens again.
I like the production quality tho, very good. The recent chiller video was good too.
Can’t agree more with this comment. Resetting and walking away without doing anything usually will result in a call back. He’s learning and has the drive, in a few years he’ll be more understanding. I
1:23 i guess you owe me a drink :D
A double scotch neat please.
I'm pretty sure you owe me a drink now 😅
I had a same model York yeet the keyway like that before. It threw the belt and wouldn't heat. Seems to be a common problem. Makes sense because York rooftops are trash.
God Bless America
I find HVAC and the like fun to watch! Better than pranks and crap. I also watch electrical, electronic repair. Wired up my big shed and the pro looked it over and stated it was factory safe since i use laser cleaners, soldering, welding for retro repairs and restorations for a hobby that makes pocket money
May take up repairing HVAC boards for old systems with no parts.
heck yea
Buddy, you need to get yourself a drill for all of those panel doors. You can be saving so much time.
Too low of gas pressure snd burners need to be scrubbedd along with pilot tube.
That switch tripped for air reason. Weak switch. Low airflow, ect.
the pully is upside down, thats why the pin came out
you are the NUMBER 1 HVAC U TUBER
thank you brother!
Use vice grips on that thermocouple m8. Banging on stuff to get it unstuck is fine, but do something to prevent it from happening again (oil, lube, wd40, ky jelly). Also, please get some power tools. :)
Vice grips are a must ! Ever tried pbblaster ? Have some brass integral shutoffs on 94 moen shower mixers that are not interested in moving - already stripped one set.
All that black stuff around the fan motor is from that belt
What bag do you have I am going into HVAC and that bag would help me out a lot
Time to replace equipment
1st unit, maybe plugged filters?
It’s called a key… that’s not how you tighten a belt buckwheat…. You changed airflow.. you should slide motor over to tighten belt not change ratio.
Need some Free All brand spray or pb blaster for rusty crusty pipe fittings
Them yorks urgh. Keep the update on a usb drive to update that simplicity board when ever u see 4.1 or 4.0
Same bag same meter in same spot lol
While it is quick and easily accessible, the exhaust is NOT the best place to warm yourself up.
Why?
Because it is full of moisture/condensation and will end up making it worse.
Whenever possible, pull the panel that you would inspect the heat exchanger from. This is straight heated air and no moisture/condensation.
funny , looking for the limit first instead of what could cause it first
Well hey at least they aren’t Reznor .
its winter gets gloves and cold gear on man ur on the roof very cols
gloves make it harder to do stuff
Crash before a storm of course it does it’s an unwritten rule!
man what happened? no videos in awhile
That not a pin it’s called a key. You are so green bro but your videos are good.
Oh and get some damn gloves bro!!!
No offense… lose the ridiculous background music. All of the best content creators have done so
And by doing that with the pulley. You just raised the amp draw on that blower motor. Vice grips would’ve got that off. No need to replace the gas valve unless it’s bad.
I hope you charge hazard pay for working in the snow
Why are these things happening? Cold .... cold causes metal to contract a bit ... could have just been that mil difference enough to cause things to behave in weird ways...
This guy really has no clue what he’s doing does he?
Worked on one of those exact piece of shit JCI units
Good video but the music is very annoying, way too loud compared to your talking
Frozen regulator
Your no rookie, that owner of that company you work for better be damn happy he’s got you working for him. Please tell me your W2 is at least 75 to 100K per year!!!!!! Plus benefits.
He threw the air balance of the building off to adjust tension when there's a system for adjusting tension RIGHT THERE! He's 100% a rookie and needs to be working under a trained JMan.
Man.. you don't have a drill? Complaining about your cold hands and doing that as slow as possible lol
Not worth crap have step thru, in union hvac shop!
What?
First video of yours I've seen. Not sure how long you've been in the field but it doesn't seem like you should be out running service calls on gas fire equipment on your own. If I was the first customer and found out you just walked around and reset all the units and said they're fine now I would not be paying that bill. Can't even adjust a belt properly. I'm not saying you're an idiot but you need much more training before being sent on your own for your and the customers safety.
Whole lotta guessing going on here. These are basic problems.
Those York RTU's are such a shit design 😂
