20 comercial ac units - Page 2

12,000Btu = 1 ton of refrigeration

After one is scrapped you will know how long it will take to do all or sell whole.

I will personally thank you, since I'm on the smf app

Where are they located ? Will you crane down or will you just receive? Can you transport easily . What is the total weight whole. One unit. I'm bad at math but the numbers and equipment decide. Got a crew ?
Stop .....This hole is deep.
Now ! Details!

Ok let's go over this, are the units on building roofs tops where you have to meet the crane and remove the units as they come off the roof ? Or are they in a storage yard? There are lots of important factors in these questions, I do this type of work regularly,

The building is going to be torn down to make room for a condo development so I'm just going to leave the shells on the roof. It also has 3 stage power. Building had a lot of equipment in it so there are a lot of thick conduit cables running all over the place.

Ok so you will have to hire a crane at your own expense is that right?

In the Mechanical world one ton =12,000 BTU best I remember

What is tons referring to?

Forget about all the BTU NUMBERS THATS NOT IMPORTANT WHAT IS IMPORTANT IS THAT YOU HAVE THESE UNITS DO YOU HAVE TO PAY FOR THEM?

Good luck 1956.

Does this mean that you will strip the units of components; coils,motors,refrigerant lines,switches,wire,contactors,relays,etc. and leave the unit housings on the roof curbs? If the power has been disconnected from the units than any "thick conduit cables" should be of no consequence to you regarding removal. If power, whether single or three phase, is still connected to the units I hope you will use proper electrical safety precautions.
I have done very well removing and scrapping HVAC equip. there's a fair amount of money to be made in the right circumstance.
Best of luck to you!

Wow, wish I had that deal myself. I have a 32 ft flatbed trailer I was hotshotting with, and could fit 10 - 16 of those on there (depending on width). I have hauled many new units for Lennox, and wished I could get in with the AC companies that install them, but all of the employees scrap them for extra bux (cant blame them). I personally have only taken two commercial units apart, and the worst thing about them was messing with the compressor in taking it to the yard.

BTUs is a unit of temp, a ton is a size.

12,000 BTUs = a ton.

When you are figuring how big of an AC you need to install you use BTUs.

Properly Sized Room AC : ENERGY STAR

Once you figured out how many BTUs you need, you then would decide on how big the AC unit needs to be.

If you need 36,000 BTUs to cool a home you would need at a min, a 3 ton AC unit.

This is just a general rule of thumb and certainly an oversimplification. There are many other factors that change an AC size. Such as climate, shade, insulation, amount of windows, direction the house is facing, amount of rooms, layout, ect.. Many homeowner try to purchase their own AC units and buy the wrong size just because they look at feet/BTU.

I was trying to walk you thru the right way to scrap these machines on the forum so other people could see how it should be done. First I pay my contractors for these units, most of the time they would be swapping out the old units and replacing them with new ones. Ok I pay for these large commercial units a rate of ten dollars a unit ton, meaning a 10 ton unit I pay $100.00, a 25 ton unit would be $250.00 each and so on.Talking in general terms, you have to be on the job site early the reason being the crane will usually take down a old unit first, because the contractor will want to put the new unit in the old ones place so when doing a job with multi swap outs make sure you have enough trailer or truck space to remove the scrap units. So when you get them back to your yard, the first thing we do is remove all the side panels/ covers, once that's done you can see what you are working with,most of the sets of coils are set in a tin molding that allows them to slide one side of the units coils in place at one time when they are manufacturing them. We are demanufactors and want to remove them the same way, doing it this way allows you to pull several coils out at one time we just hook up a long chain to our fork lift and pull the set of coils out.Now before that's done you will have to cut all the copper lines and any wires that would stop you from pulling the coils out, after you have the coils out you would cut all the copper lines and wire out, then we would remove all the electric motors that control the large fans,that would be easy to remove now instead of pulling them out they would fall to the ground.The compressors are the heavy pieces that we remove by using a touch or a 1/2 inch drill bit once lose we hook up a chain to the compressor and the fork lift does the rest.The rest of the shell we load on a flat bed and they go to the scrap yard, the tin is the area of the unit you want to spend the least amount of time on for obvious reasons so try not to waste a lot of time on if you do not have to.Most of the time the freon would have to be removed before you start stripping out the unit. These units are gold mines to scrapers and they are pretty easy to scrap out. The bigger the unit the faster we scrap them out, Once you do a couple of them it's pretty easy.Go for it Good Luck it hope I helped you out a little.
