- 460 volt Copeland Scroll compressor sorted to ground after just 2 years. Replacing a 95 Lbs compressor on a high tall roof can be challenging if you have to lift it manually. My ultimate HVAC Ladder Crane made it easy.

Here is the full video of this HVAC Crane lift I posted a while back. czcams.com/video/6G95R3krvmc/video.html
Day - month - year = perfect
I built an A-frame style 4 pc. lift frame that mounts on top of the curb hatch frame. Used it recently for lifting a heat exchanger replacement up through hatches at a job with no permanent ladder recently. Built it to lift a compressor up to a roof before Covid and has been rusting on on a shed floor since then. My employer did not contribute to its fabrication and it still needs an electric winch but it got the job done and no bodies were injured.
You need a helper for the heavy lifting.
ingenious winch arrangement! it would have been handy the other week for hauling roofing material on the shed. those rolls are heavy as
Rick, I am really impressed by your work knowledge !!
Another great video Rick! This trade needs more techs like you.
Your to kind! thanks man!
I dig your work smarter not harder ideas. You will stay healthy much longer too! My dad taught me this a long time ago. You can work smart or be dumb and tough, and Im not that tough.
Yes sir!
Awesome video from the PRO
This is why i left the trade after 12 years and went to the local gas utility company, my back could not handle compressor changeouts anymore, now i jut do gas leaks and turn peoples meters on and off, deff miss that type of workout but my back dosent, love your videos keeps me fresh even though its been 6 years since ive changed a compressor.
u are the macgyver of hvac nicccce
😂👍
Great job Rick.
What you really need is an XtraMan hoist. Unfortunately they don't make them anymore. I set a few hundred refrigeration and A/C compressors with mine over a three year period. You could make your own if you could find the specs and a drawing.
I’m convinced he made with channel to show off all his cool tools 😂 keep up the good work 🤙
winner winner,,,LOL
Very strong suggestion. Get yourself wing nuts. Another alternative is expandable lock pins. (or Clevis, or Slide-loc, or possibly PopPins. )
BluVac micron gauge definitely agree with you 100% the best micron gauge hands down in its own category.
Remember i ordered some coil cleaner with Tru Tech, they dropped one of these in there for FREE so thought it wouldn’t be much. Things a trooper🤣has survived many oil logs and stupid moments of a young dum tech & she’s ready for more tmr lol
I've been very happy with Blu Vac
Muy bueno maestro, desde argentina saludos excelente el procedimiento realizado en ese equipo ojala vean acá como se trabaja a ese nivel con esas herramientas que poco entran al país
Thanks for letting me know where you are and supporting the channel!
Great video as always Rick. You have all the cool tools!
Shopping list for Mr. HVACR survival longer rope and a pulley (work smarter, not harder)
You are simply a badass. Great job.
You're too kind, thanks for watching! 🤜🤛
Very good setup. I like your thinking 🤔
very nice work,would love that ladder crane,at my age,thanks for sharing
2- 6 ft ladders and a 4x4, with a chainfall works well
Proper engineer 👍🏻 top bloke
Great Video . Thank you for sharing
Great job Rick!
Thanks Steve! 🤜🤛👍👍🙏
Nice work Rick
Thank you!
Awesome, as always 👍
Thanks so much🙏👍👍
No bubbles, no troubles.
I prefer buddie its easier
@@ryanisaacson118 ???
They taught us in school, using a belt tension tool, that if you can roll a belt on, it is too loose. "Bell & gosset"(?) Or someone big like that did a study and over 90% of techs put belts on way too loose.
Rick used belt tension measurements many times, mainly on ice machines. I guess sometimes you’re feeling / experience is enough. Especially when the tool is 15 minutes away to get it. 😏
@@brauchmernet ya, I have the tool in the truck.
Cool video
Thank you!
4:20 I use the same winch but I have a bracket that hangs on the strut for when I hang kitchen hoods. That’s a good idea though. Yet I’m still trying to figure out a portable gantri for lifting rtus but good video Rick 🫡👍 keep up the work.
If I'm doing a full size unit that's when the real crane is coming out.
1st class video 👍👍👍👍👍🇺🇸
Much appreciated 👍
Keep it great job
Thank you!
I just bought a miller electric 11-1116 it's a tiny little torch handle and it comes with a bunch of tips and stuff. It's freakin awesome, it makes the big torch handles obsolete in my opinion. Don't get me wrong the big handles work fine especially with big stuff. But for 90 percent of what we do especially reach ins and prep tables and stuff it's the tits.
i feel the same👍
👍👍👍
Makes me depressed thinking about how bad my vaccum rig is compared to what you guys have ...
The one thing you could do to make the job even easier is to rope up a little foldable trolley/platform and wheel all the heavy stuff up to the unit .
Avoids having to carry it all the way there .
I lowered most of it off the roof, my rope nearly reached the ground, I got another rope this weekend so I can trigger the hook next time on tall roofs.
Honestly would had it brazed in by the time I would set up crane old school I guess
👍👍
👍👍👍
Great video man. Just wondering how much your crane weighs in relation to the compressor. that would be a good comparison. Seems like you ropped up the winch anyway and if they’re similar in weight what’s the difference. Also Seemed like a little bit to set up. I’m not knocking it, I think it would be great for a lot of applications, too many steps for others
It's in Three pieces, the the brackets are probably 15 to 20 lb each. The compressor weighs 95 lb total. It's a lot more manageable to take up the three small pieces. Let's also take into account what happens if you drop the $2,000 compressor? Who's paying for that and who's paying for the damage to your body if you pull something in your back?
where is your hand truck? the best lift i have done when i did refrigeration work. i had a convenient store and it had a bad comp on a rtu cooler unit. i took some thick unistrut and made sort of a upside down L PUT A 45 DEG support connecting the angle then bolted it to the steel ladder on the back of the building, the unistrut was fastened using a pipe to the ladder so i could turn the L bracket. i lifted the comp with a come along then turn the L bracket and set the comp on the roof. left it on the job site for next time
My fold up trucks wheel broke last week. This Lyft does three different ladders plus a trolley. Check it out. czcams.com/video/6G95R3krvmc/video.html
Dang that’s the 3rd compressor in there ?
Says who?
@@HVACRSurvival well I thought so because it had that writing on it and for some reason I thought original one failed and you wrote that on the new (2nd) one but then I realized you probably wrote that for warranty purposes
@@joeshearer1247 correct, I thought I would be back shortly after finding the fault but they waited till spring the next year.
Are there any channels like this for the hot side

Hey Rick a question there bud have you ever had any problems pulling a vacuum with the c&d core depressor? I bought a set but always having problems with them
They have been better than Appion core tools for me. You can buy new seals.
NAVAC CRT's are the bees knees
Wait, you guys pull vacuums?
We just installed a similar model on an older Carrier unit with a b tank. Struggled to heat the suction line. If you didn't use the rose bud, what else would you recommend? Thanks, Rick.
I have used a number 2 tip for years and years with no problems. I'm just looking for better and faster ways of doing things.
paint the gasline for godshakes
Telling the wrong person.
Curious Rick, I see you and others on the net using a true oxygen / acetylene torch; why?
All of our trucks are equipped with an acetylene only torch rig and we have no issues.
Oxy acetylene torches run way hotter, more expensive to use though. The benefit is in the difference in heat the flame produces. Air acetylene cant compete in speed, especially on larger pipe. They both get the job done!
It's what I use mainly because that's what they gave us, I used to love the turbo torch when I didn't know how to use an oxy acetylene torch. Once I learned how to use it then I didn't like the turbo any longer because it's slower as far as the speed at which it gets hot and the heat concentration is very broad.
305 thumbs up
🤜🤛👍👍
Honestly, I have found that it is way easier to just carry Sporlan brand bi flow filter driers, you can’t install them incorrectly, I know it seems kinda dumb but it helps protect from dumb actions which we all do on occasion. And seriously, what is this talk of pulling vacuums? Lol
Vacuum, that's just suggested😆🍺🍺
blow and go!
Are 460 motors always 3 phase?
Always is a big basket but I believe they are. I haven't seen any that weren't.
there are a fair bit of single phase 460V motors out there, they're mainly lower power devices like condenser fans, blowers, draft inducers and such, in big commercial refer/hvac.
the whole reason is that big three phase RTU's/racks rarely have a neutral wire to use 277V single phase. so they most always use two of the 480V phases.
you have to be careful on that in 480V units, it's easy to accidentally(head up rear) put a 208/240v draft inducer on an 480V unit. 🤣 in which goes smoke emitter pretty fast, someone just recently did that on one of the HVAC channels, I forgot which one.
Nice video but you could’ve had the compressor on the roof in a fraction of time that it took just to set that device up. Not to mention that when you add up the weight of the motor and the brackets, it probably totals as much as the compressor itself. I could see using it on larger compressors, but not on that tiny little thing. No disrespect intended. Just my opinion.
95# was the total weight, how much money do I lose if I drop it? It doesn't look very big but it weighed a lot more than what it looked like and pulling that straight up a ladder kind of sucks. The winch weighs 20-25 lb and the bracket weighs maybe 20-25 lb.
What winch is that?
Harbor freight 120v
I need that hook
Buy or build it. That's a major time saver if you're working on roofs.
@@HVACRSurvival where you buy it
@@SoutheastHVAC amzn.to/3nFwCUy use this link to support my channel
That panel being off while checking pressures needs some explaining.
Pretty simple to explain when you weigh in the exact charge, it was cold outside so it's not going to be off by much.
@@HVACRSurvival As long as you understand that you were totally bypassing the condenser coil, which is not how it was designed to run.
How is this not a 2 man job? Jesus Christ
What is a second guy going to do? Honestly, Lift it up the ladder? This was a small compressor. We might get a little help if it's a 25hp semi-hermetic compressor on a refrigeration rack.
Awesome video Rick. Thanks for sharing. I use an A17 tip for bigger copper. Had to sweat some copper on an Intellipak. Suction was 2⅛" and it worked flawlessly.
I have that one but I was told my torches are to small for that head.
