Window ac units

I'm going to be getting roughly 80 window ac units not sure what sizes they are but but that's a lot for me I did 28 once so this is a step up haha. Plus 6 central ac compressors 6 central ac fan motors and 6 of the control parts the part with the small transformer and the capacitor. I can kinda guess Going to be close to 1k in scrap if I break it all down I think. I usually do it like this radiators first then motors then the compressor tanks last cause they take the longest time. Wonder what a rough weight estimate would be?. Space is going to be a issue tho even if I stack them 5 high that's lots of acs haha.

Have you factored in the cost for evacuating the Freon AKA CFC's.

Link: U.S.A. Schnitzer Steel Inc. has agreed to pay a civil penalty of $1,550,000

LINK: Environmental violations results in $225,000 fine for CRC Canada Co.

That's already been done by HVAC guy. I didn't pay for it so it's not a factor for me. So what would I be lookinging at value wise ?'clean rads are 1.65 a lb num 1 copper is 3.10 a lb and num 2 is 2.90 a lb currently as of writing this.

The freon guy just did ours Mike. It's nice because he pumps the oil out of the compressors at the same time as he is removing the Freon. We get window AC's, portable AC's, and dehumidifiers. I break them down as they come in. All that's left after i do my breakdown is just the sealed units and the al/cu radiators when i'm done. The whole thing is intact with the freon still in it.

Having it all broke down makes it easy for the freon guy when he comes in. He bangs em' out in no time. I just did about 25 units.

Just my opinion but you don't really get all that much out of it. Especially since it's so time consuming. You get a little bit of oily #2 copper. A little bit of steel. A couple of cu/al radiators that have to be cleaned. A sealed unit and a fair amount of plastic & styrofoam trash that has to be gotten rid of. All in all ... it's a fair amount of work for not all that much gain.

I guess it's a sign of the times. The ac's & dehumidifiers don't seem to last more than a few years now. Most anything i see with an electric motor these days is aluminum wound. It's in just about everything you run across. Even the Generac portable generators.

Point being: You may find that a lot of the sealed units you get are aluminum wound. You would be better off not to bother with trying to break them down. Just sell them whole and be done with them. It's all around oily and time consuming work otherwise.

As for actual yields and values at the end of it all .... i don't actually know. I'm not seeing all that much value for all the work that goes into it. I would recommend staying with the central AC's if they are what you know. They're quality built and costs thousands of dollars to buy new. That means more scrap value when they reach end of life.

The cheapo Home Depot AC or dehumidifier that sold for less that $ 100.00 ? There's not much value left when they go off to the scrap yard. Even some of the CU/Al radiators are all aluminum with no copper these days. It's what you get with cheap consumer grade goods that were made in China.

Hills nailed it, aluminum has defiantly replaced copper.

Aluminum is a fantastic metal with my home foundry was able to turn my scrap cast aluminum into a useful product I was able to maximize my profits.

Good luck with the window AC's Mike1, hope you turn a profit, I would take Hills advice - take them straight to the yard.

These are old from 80s and 90s acs. I'm looking at close to 1k I think with today's prices. Maybe more. Rough estimate . If I was able to put up pics from my phone I would but won't let me do it haha. I forgot what tools you need to unbolt the compressor?.

I got 65 lbs clean rads from 2 central ac units. Packaged units with vents no A coil I guess the part with the blower motor is the A coil ?.

I hope it works out for you.

It took me awhile to develop a method for doing the teardown on window AC's. Hard to describe exactly. The two places i find the most difficult are the compressor bolts and the two phillips head screws that hold the fan assembly in place.

You'll need a really long phillips head screwdriver for the two phillips head screws that hold the fan. Sometimes they rust up. If that's the case .... flip the AC over and grind off the screws with an angle grinder. Take a pin punch and drive them through from the outside.

Most of the nuts that hold the compressor are either 10mm or 12mm. You'll need a socket,a wratchet, and a foot long extension to do those ones easily.

It just takes a little practice to get the knack of it. After awhile ... you can bang em' out without too much trouble. Most of the newer ones are pretty much made the same no matter what the manufacturer's name is.

Plasma.

Oh good I was wondering what the socket sizes were also is the thing that holds the compressor bolts in is that cast aluminum? I counted 36 acs in one trailer and either 3 or 4 rows of 5 high stacks of 15 each. Getting the rads off isn't to bad the hard part is as you said the fan lol. The compressor is easy enough if I had the right socket lol witch I didn't that's at home I was at work. I'm just going to have to transport 20 or 30 at a time can only fit 20 in the shed and probably 10 outside the shed being in a trailer park they don't like stuff siting outside or I would have them all there haha.

Also it's been a few years since I've done a window ac not since I did 28 of them in 2022 I think. This is the biggest haul I've ever had to do

It was a little quieter at work today so i started breaking down some of the AC & dehumidifiers for something to pass the time. Each compressor had a nut & bolt arrangement holding it to the base of the air conditioner. Most seemed to be metric. Somewhere in the 12-14 mm range. They aren't hard to do as long as you have a 12-16 " extension.

I've decided that the first thing i like to do with an AC is flip it upside down and grind off any small screws that are poking through the bottom. Then i take a 1/8" punch and drive them through. It makes it much easier later on when you open the air conditioner up. The fan assembly is already flippy flopping around. The whole works almost comes apart in your hands. No fussing with those small phillips head screws buried way down deep inside.

It seems like there's a lot of phillips head sheet metal screws holding an air conditioner together. I use a smaller battery powered impact driver for that job. You can buzz right through them all on no time with the right tool. It would be slow going with a screwdriver.

There's no aluminum to speak of in the air conditioners i've done so far. The base is steel. The outer shell is made of sheet metal.

The dehumidifiers i did today were almost entirely plastic. The only metal was in the compressor and in the rads.

You might not want to use a torch of any kind on an air conditioner compressor bolt. The compressor sits on rubber shock absorbers. Also ... there's a ton of plastic and styrofoam in that area that would catch fire and make toxic smoke with any amount of heat in the area.

All around ... the ac's and dehumidifiers aren't all that bad to do once you develop a method for the teardown. There doesn't seem to be a whole lot of value in there. The main reason i dismantle them is just to have them all ready for when the Freon removal technician comes in. He can bang out 50 or 60 units per hour if i have the job set up right for his arrival. It keeps him happy and saves us a ton of money on his labor costs.

extensions

I have MANY extensions of all sizes as I find that they are the tool you need sometimes.

I also believe that you can never have to many drill bits and saw blades.

Have a nice collection of punches and chisels also.

Has anyone ever gotten different types of window ac units that have a fat small radiator on one side ? I noticed there are different window ac types how many types has anyone come across? I think it's a 1988 ? What's with the ones that are all frilly and look like Christmas tinsel? I don't see those often.

I had an ac with the tinsel stuff a number of months back. It's hard to remember but i think it was harder to tear down. Also had a dehumidifier like that. I think the rad coil might have been made of steel tubing or something like that. Not all that good for scrapping purposes.

Rather than fuss with them ... i just opened them up enough so that the freon tech could reach in and do his part. The whole works went right on the junk pile after the freon and oil were pumped out.

Did the disassembly part with a backhoe on those ones. >:)

I had a all alum ac once. The base and shell were all aluminum and it had the weird tinsel coils in there. must have been from the 70s

I also came across 2 permanent wall mounted ac's from an aprt complex a few weeks ago and they both had 2 fan motors in them. weird

Well some window AC's have two motors in them or one big one that can be a pain to open haha. I think there is going to be a few with the tinsel not sure yet. Going to have a lot of loops when I'm done that's for sure a 5 gal bucket full I bet. I think it's going to be close to 80-96 window acs of different sizes. Some are heavier than others. Wow a all aluminum shell cool.

Haha a backhoe that's great I bet that is a site to see. I did encounter a coil that was steel didn't know they made em like that terrible haha.

The backhoe has a thumb on it Mike. It's pretty useful for doing the teardown on washers, dryers, fridges and stuff like that. The whole idea is to flatten them out and compact the metal so they can fit more on a truck when the scrap yard comes to pick up our metals.

The cooling lines that are built into the walls of a chest freezer are kinda weird. They aren't copper. I think they're some kind of steel. Maybe stainless steel ... i dunno. I don't see much copper in a household fridge or freezer except a little down by the compressor.

There was one thing about the rads i thought to mention :

You were asking about sawzall blades awhile back. It seems like different kinds are good for different jobs. The best ones i've found for cutting the steel ends off the rads are fine tooth sawzall blades. Look for 24 TPI. That's 24 teeth per inch. They give you a cleaner cut with fewer ragged edges. The steel ends come off a lot easier that way.

The finer tooth blades make it so the piece you're working on shakes a lot less when you're cutting it too.

I use 24 tpi blades for cutting catalytic converters off, the more aggressive blades don't last very long on pipe

I feel like i'm still figuring it out sometimes. They seem to recommend the finer blades for thin metal. Stuff like sheet metal and thin wall pipe. The coarser blades are for thicker wall pieces of metal like brass pipe and black iron.

Ya gotta figure in the hardness of the metal too. Brass and copper are pretty soft. The blades hold up pretty well. Stainless ... like what you would get around a cat ... that's a pretty durable metal that's harder to cut and harder on a blade. You have to take your time with it and not heat up the blade.

It's a long story but i was cutting a 3/4" stainless nipple off a stainless tank last week. Had a brand new coarse blade in the sawzall but i smoked it cause i was in a rush and being impatient. An angle grinder with a 1/16" thick cutting wheel would have been a better choice for that job.

Oh yea I did a fridge once lots of foam what a pain that was. So what makes more copper dust when cutting copper ? The smaller teeth or the bigger teeth?. I usually use a 12 inch carbide diablo blade for central ac compressors I used a DeWalt one a few times once I snapped it off near the base one I bent like a s haha. One thing with diablo blades I never have broke one it did bend a little but not like DeWalt why is that I wonder ?. Are diablo blades thicker or something?. I know they are made in Switzerland so that's cool. Now I just need to find some impact bits that are made in a European country most of them are made in China😕. What weighta do the clean rads come out to be on window ac units ? I was thinking 6 lbs when clean ? I think most of them are 8k btu does this impact radiator size of the tubes ? Or is the year what dictates the size of the tubes ?.

I hear ya on the fridges. They make a mess when i compact them. Foam and plastic all over the place.

Fine or coarse blades don't seem to make much of a difference in the amount of copper dust. One thing i don't much like is all the dust that gets thrown up in the air when cutting with a grinder. It's a messy job. Good idea to wear a mask, safety glasses, and gloves.

Some of the sawzall blades are more brittle than others. It all depends on what kind of metal alloy they used to make the blade with. The ones they make these days seem to be more bendy. I haven't had one break off down in the chuck for quite awhile. If they bend .... i just hammer them out flat again on a flat metal surface like an anvil. The main thing just seems to be using the sawzall the right way and not letting the point of the blade go crashing into something. It should stick out a couple of inches past the thing you're cutting on the shortest part of the stroke. The other thing would be not letting the metal bind the blade when you're cutting. It's kinda like cutting down a tree and not binding the chain saw bar. If you ever got a chain saw stuck in a tree and had the hassle of getting it free .... it would make sense. Sometimes a thing you are cutting will close up on your blade. You can feel it start to bind. It's at that point that you want to stop cutting, pull out your blade, and figure out why it's binding up on you. ( The instinct is to try and force it through but it's better not to do it that way.)

I've been using a Ryobi impact bit kit for over a year now. It's worked pretty good. I've only broken one nut driver bit. The thing about the screwdriver bit tips is that you want to find the one that is the exact right fit for the screw you are trying to undo. Once an impact bit slips .... it either boogers up the screw you are trying to unfasten -or- it boogers up the bit tip a little. You wanna remember too ... the bit tips do wear. Especially the ones like a # 2 phillips that you use a lot. They're just like a sawzall blade or a grinding wheel. They're disposable supplies. You throw em' away and replace em' with a fresh one every so often. All part of the cost of doing business.

No idea of the weights on the rads. They vary in size. Maybe a pound or two each ? Not a good money kind of thing but they eventually add up if you do enough of em'. Like most other kinds of scrapping ... it's just a quarter here and fifty cents there. Maybe a buck or two if you run across a good one. It's a lot like work.

Oh yes I no that all to well lol when I did 28 of em took me a month haha. Now I'm going to have 80-96 of them haha. I got a truck guy how many ac units would fit into a truck bed? They are 8k-8200 btu does that make a difference in size of the space it takes up?.

mike1 why would you cut up 28 refrigerators with a sawzall.

If your using a regular long box pick up truck, to increase your load capacity install some stakes in the pockets and pull a trailer to make the best use of your fuel.

The roof top AC condenser rads are about 6 / 8 inches thick, I use fine tooth blades to cut the copper ends off. The copper ends are soldered with an alloy with a percentage of silver. Easy to recover the silver via a copper parting cell.

Not all, I've seen some consumer grade AC's were they used epoxy.

I can see how it would take awhile to break down 28 window air conditioners. Breaking down 80 + will keep your hands busy for awhile.

It's hard to say on the truck. It used to be that we called in the freon recovery company once we had accumulated 50 Freon units. They would be a mix of freezers, fridges, window AC's, and dehumidifiers. They would come down and haul it all off to their shop.

After awhile ... they figured out that it was a whole lot less time & trouble to send out a freon technician with a van full of equipment and remove the freon on-site.

It made quite a bit of extra work for me. Now ... i do the prep for their arrival and deal with the scrap metal after they are done.

I try to look on the bright side. All the extra work that got piled on my shoulders makes it so i have to put in overtime to get the job done. Cha-Ching !

That's where the real money in scrapping gets made. ;)

I meant window ac units not fridges haha. I don't really do fridges.

Yea I did a quick count of the ones I couldn't see in the trailer stacked 5 high looks like 160 acs haha.

Whoo boy .... that's an awful lot like work Mike. I wish you the best of luck with it. You might make some money with that many rads & compressors.There's probably a bit in steel and electric fan motors too.

I know right haha. The rads are easy enough to pull out I did 10 at the work place on friday

Compressors after copper extraction is going to be 3,306lbs I have 6 central ac compressors to. 960 lbs of clean rads if they weigh 6lbs per ac, fan motors 166lbs of fan motor copper can't remember if the small fan motors were a lb or the two tiny motors since some have either one big motor or two small fan motors never figured out why. Either way it's going to be a lot probably close to 3k depending on price when I get them all done haha. I thought 28 took a while haha. 166lbs of loops I'm figuring 1 lb of loops per ac I might fill up a 5 gal bucket with loops haha.

Might want to sell the sealed units as is.... thats alot of time / work cutting all those. also then having to dealing with all that oil.

One good thing about having the Freon removed is that the tech usually pumps the oil out of the compressor as well. Still an oily job though. I think Mike may find that most of the compressor motors for the window AC's are wound in ali and not copper. 80 - 90% of all electric motors i see these days are ali wound. It's in everything. Even in generators. What a buzzkill to put in the work of breaking the motor down just to find an ali winding.;(

Every Condenser unit i get from the hvac shop, my tech buddy or a random find that have the freon removed always still have the oil. i wonder if removing the oil is an extra part of recovery that they leave the oil in to do the job faster.

I hear ya on the Alum units and motors. I had one of those 200lb S units i wanted to breakdown. i did 4 others in the past and when i did the last one it was alum windings. that was when i retired from opening sealed units. I also have found alum motors from generators. Its like i got 12lbs of copper coming to go to nothing but shred.

To remove the oil requires drilling and draining into a suitable vessel, quite often a bit of freon remains in the oil.

Hot sparks from a zip blade, cutting torch of plasma - nerve gas.

AET recommends that our clients have their HVAC units serviced annually in accordance with ASHRAE recommended maintenance prior to the start of the summer cooling season. Note: FREON release in close proximity to an open flame may result in formation of phosgene gas.

Ummm ... i dunno. My understanding of their part is limited. If i were to take a guess .... it might be that your HVAC shop and the Freon recycling company we're using have different end goals.

The HVAC shop and your tech buddy are just looking to vacuum out the Freon into a steel refrigerant tank and dispose of it somehow. They're prime gig is new refrigeration installation and repair. That's where they make the bulk of their money. Evacuating Freon at end of life would just be a sideline for them.

The Freon recycling company that we have been using is a different kind of animal. They're based two states away in Massachusetts and have a tech with a van full of equipment that travels hundreds of miles every week around the state of Maine. He goes from Transfer Station to Transfer Station processing fridges,freezers, AC's, and dehumidifiers once they've been sent to the dump. That's all this company does and they're pretty good at it. They bang the work out like nobody's business. He can tear through something like 50 or 60 units an hour if i have the job set up right for him.

I was talking with him the last time he came through .... about a month ago. All of the Freon and oil he collects goes back to their shop in Massachusetts. The different kinds of mixed Freon in his tanks gets run through a separation tower and sorted out. Each kind is lab tested to ensure purity and is re-sold to be used over & over again. Their shop is something like 50,000 sqft. It gets cold here in the Northeast here in the winter. All the compressor oil he collects is used as heating oil in their waste oil furnace and heats the building for free.

I guess it's a pretty big recycling outfit. They've got techs with vans running all over creation in this part of the country. The changeover to a newer way of doing things made for a bit more work on my end but i can't say i'm opposed to it. I try to support all of the different kinds of recyclers coming through the place as long as they're doing a good job.

AET recommends that our clients have their HVAC units serviced annually in accordance with ASHRAE recommended maintenance prior to the start of the summer cooling season. Note: FREON release in close proximity to an open flame may result in formation of phosgene gas.

It doesn't seem to be a big problem bro. We've been here for awhile. To the best of my recollection .... i've never heard of anyone being harmed this way. The few that have been doing sealed units don't seem to stay with it for a long time. It's quite a bit of work for not much gain. Especially now that so many of the motors are wound with aluminum and not copper. Some jobs just aren't worth doing. There's probably more money in making youtube videos telling people how to scrap than actually doing the work itself.

If I had as many evacuated compressors as Mike1 claims to have, I would cut the tops off just above the weld- removed the four bolts holding the copper windings then sell it as breakage.

Years ago made a rotary table to plasma cut items like refrigeration / AC compressors and propane tanks, my table is not as fancy as the one this dude made.

We're kind of getting off on a tangent but this would be the machine for processing large numbers of refrigeration compressors. I'm not sure about the tall thin ones that you often run across these days. They're like doing a regular electric motor. The stator is friction fit into the outer steel jacket. That kind needs one or two lengthwise cuts. They are harder to do.

All the more reason to just sell them whole at the scrap yard i suppose. There are times when the juice just isn't worth the squeeze. Just toss the darn things in the shredder and be done with them. Move on to something more profitable to do.

Ahh well ... we're all getting older and times do change. You kinda have to roll with it and adapt accordingly.

Joe's last post was in late 2018. The last time he logged in was 2020. You just don't know. Covid or something else might have gotten him. A lot of us have fallen by the wayside over the years.

I suppose the point of it all is that things have changed quite a bit over the last 4 - 6 years. Joe's numbers were probably based on copper wound compressors. He probably didn't get all that many aluminum wound clunkers back then. Nowadays ... the clunkers are far more common.

The copper yields would probably be even lower than what Joe's numbers indicated now that we are here in late 2024.

Don't mean to be the Debbie Downer it's just that you have to be practical minded and keep it real when you are scrapping. Sometimes the world around you changes. A thing that might have been worth doing years ago might not be worth doing today. I hate to see people needlessly chasing their tail in hopes of making a few bucks and a better life only to come up with the dirty end of the stick. :(
