Window ac units - Page 9

The compressor on the portable was a little bigger but otherwise it's about the same as a window ac. The main reason it took so long was because it was a busy day with customers coming in. All the people who work for a living come in on a Sunday cause it's their only day off. They keep me pretty busy between running the compactor and answering questions about what goes where. The workday goes by fast when you're busy.



I bet you'll be banging those ac's out like nobody's business once you've done a trailer load. The main thing is to stay focused on the task at hand. I've found the less i talk ... the more my work on the bench gets done.

Those are called PTAC Units, or an Packaged Thermal Air Conditioner. They are used in aprts, hotels, schools, ect. Pretty much widow Ac unit with a heating coil thats permanently mounted threw the wall, but its still like a window unit with around 80 - 100 screws

Thanks for posting gt. I know they've been around for quite awhile but i always thought they made heat by running the ac in reverse like a heat pump. It's a good day when one learns something new.

That's exactly what I had probably older. I'm going to cut ends off of rads today.

I did a couple ptac units from 1972 last year. those were awesome. they were from an aprt building that use to be a hotel. My contact that seen them (the UPS guy) thought they were mini rooftop units when he text me about them. "What can brown do for you?"

Neat mine was smaller and no blower motor of course haha. Both of them with ends off was 12lb. I did what was left of the radiators I had I got 280lbs so that would bring the total of clean ac rads to 679lb clean ac rads with 91 acs to go ��. So far I have taken in 29lb num 2, 40lb num 3 wire, 19lb aluminum rads,30lb num 1. With some more num 1 in there somewhere and then all the noodles to pull out haha I'm going to put those in a bucket and see how full it gets from these I have done ��. I still have fan motors and I'm debating to either take compressors in as is or cut em open I'm going to count the tanks to see how many acs I have done some of them didn't have rads on them just the fan motor and compressor I didn't account for that.

I would sell the compressors as is and be done with them. less work you have to do

Yea I was thinking that just do like the guy said cut the contaminated copper off of it the cylinder thing and take the res in as is.

Good plan then you wont have to deal with all that oil.

Right to catch ditty they should have put the box trap with the stick and some oil as bait lmao lol. I usually cut the tops off of the AC compressors from window units above the weld then just cut the wires then pull them out lol. No oil mess. Not sure how many sawzall blades takes to cut compressors open never figured that out yet. Blades can be costly. Especially diablo. Blade cost can quickly put a dent in copper profit even at 100lbs. Maybe someone has done compressors with a sawzall and figured this out???.

Lol ... a box trap ! Good one. Maybe a pretty womans called Peggy and a bottle of baby oil would be even more enticing for old diddy ?

Not sure if that's legal though ..... it's called entrapment.

==================================

On a more serious note: You might try cutting a bit below the weld. Maybe half an inch or so. The metal close to the weld is wicked hard. That will wreck your sawzall blades.

There are times when the right tool makes all of the difference in the world. Greytruck has been using a portable bandsaw for some of his work. It's all forward motion at slow speed. It makes sense that the blade would hold up a lot longer by doing it this way. Especially if it was all lubed up with baby oil while you are doing the cutting.

LMAO .... scrapper porn. Check out the action at about 4.02 minutes into the video.

Another possibility for doing some types of sealed units would be a large tubing cutter. No saw blades or torches involved. It might be worth investing in the tool if you had a steady supply and were doing the ac compressors on a regular basis.

Wow how would I use that???.

This is how to use a steel pipe cutter.



This is the fancy machine that the big boy recyclers use for processing sealed units.



Both tools work on the same basic principle. I looked on ebay and saw a couple of used pipe cutters for sale. Still not cheap to buy .... but i think it would mostly get you around having to buy sawzall blades all the time. It should be good enough for doing most of the compressors you're likely to run into that are coming out of window air conditioners.

If you think about it ... the stator you want to get at is just press fit into a piece of steel pipe. Cut the pipe at the top and the bottom and the whole stator falls out in your hands. You could process that just like any other electric motor afterward.

You never know. It might work out to be an easier way of doing the job. It's all trial and error to figure out the best tools and methods for doing the job. The only difference between a novice and a master tradesman is that the master knows how to make it look easy.

Right haha. I'll look into that. Might be easier. Might be faster to.

The guy with the fancy machine in the second video is making more money than we are. He makes it look easy.

Here's another guy to think about. This man is exceptionally good at banging out the sealed units. He's got it right down to a science.He's got all kinds of specialty tools. You probably won't see him in the video actually doing the work though. He's the guy sitting up in the office that doesn't have to get his hands dirty anymore. This factory owner is a wealthy man.

Right the steel pipe cutter thing is like 800$. That's crazy. Anyone do window ac units that have a big fan motor with 3 rivet things on it ? What would be the best way to do those?. A drill bit?.

I think i know what your talking about. Use a hammer and hatchet and cut threw the rivet between the flanges. only thing is if its aluminum wound, you cant put it back together and sneak it in with the reg electric motors. here alum motors go as shred

I'm looking on ebay right now. The 6" to 8" pipe cutters are about $ 300.00 new and $ 200.00 used. You take some of the money you make from scrapping and re-invest it back into the business by purchasing tools and equipment that help you work more productively. It's true what they say .... you have to spend money to make money.

There's another way of looking at it too. You might say to yourself .... gee .... i saw on the video that there's this man over there in Pakistan that's set up to do the job a whole lot better than i can. Maybe i will just sell my sealed unit at the scrap yard and farm the work out to him. It makes more sense for him to do that kind of work than for me to do that kind of work. That will free me up do do something more profitable than struggling with the sealed units.

Basically .... i'm just trying to say that you have different options. You just have to decide what approach works best for your own particular situation.

I usually use my angle grinder on rivets and screw heads that have stripped. Gt's hammer and hatchet sounds like another good way to do the job. I've recently started using a meat clever to split stators apart.
