HVAC System Break Down

[injunjoe]

Equipment; Carrier 3 ton Condenser/heat pump and 3.5 ton air handler with 7.5 Kw emergence heat.

Total Weight; About 300 lbs

Steel; 150lbs

ACR coil; 57lbs

Copper; 10.32 lbs

NiCR; .45lbs

Compressor 58 lbs



Aluminum; Did not weigh

Insulated #2 wire; Did not weigh



These weights are without cutting open the compressor yet and I saved the blower assemble to make a exhaust hood to help keep my shop and lungs a little cleaner.

I also forgot the reversing value and other Brass. I'll just chalk that up for fuel costs.

Are there a lot of heat pumps down there?

[injunjoe]

Yes there are! Being the winter temps don't get to cold here. Seems they have been getting colder the last few years though!

Some on the A/C units we get are from roof tops. A crane takes it off the roof and sits it in our utility trailer. The big units we call a flatbed tow truck company. These are relatively easy to get but you'll have to pay the installer $100 but you'll receive $300 to $750 depending on the size.
One day we got two $900 units but we paid $350 each and a $100 tow. Stripped them do at the scrap yard with our saw and drills in 3 hours.
Got to grease the palms to get the good stuff up here in Canada. Everyone thinks the have gold.

That's the great part, I'm the installer and the scrapper! Win Win!

[Ptscrapper]

Thats like cheating injunjoe lol.

[KzScrapper]

Ever have a dej'a vu moment?

[Scrap Master J]

Having a efficient, well thought out plan, is not cheating. They are characteristics that lead to a success.

Have an opportunity to buy a 7.5 ton rooftop unit. What should I offer and expect to get from it?

This thread is just in time. I just scored a commercial ac compressor. How does one cut these open, or what is the easiest way? Torch, grinder or reciprocating saw?

[ryanw]

I used an angle grinder to open one up once. Just my luck the steel was 1/4" thick, and this was a tiny unit...very old I guess. It took me 20 minutes to do it, and I've never done it again

[Enduringlion]

Thanks for the info Ryan. This unit appears to have a thick shell as well. I was thinking reciprocating saw.

ive tried all three, the easiest is the torch but the oil is going to burn, plasma cutter is best but only if you already own one

I don't own a plasma cutter but have access to a torch. Thanks.

[KzScrapper]

Some yard will let you drill a hole in it and drain the oil. Price is better then shred but not as good as motor and certainly not as good as recovering the copper.

Freonjoe uses a table saw with a cutoff blade and it seems to work well for him. You need to drain the oil first though.

[Enduringlion]

I have already drained the oil. The table saw idea I will pass on for now. I may use an old circular saw with the blade set low. Thanks Kz.

I believe he cuts the cases with the plasma, then cuts the windings with the table saw.

OP, get a 4 1/2 grinder and some cutoff wheels. It's just about the 2nd easiest way to get them open. Plasma being 1st choice. JMO.
