Miami cooling What is the refrigerant your using for a replacement.

[icemeister]

This isn't about topping off R22, but it does pertain to the side discussion about recovering R22 mixed with another refrigerant.

While I'm no fan of leak sealers, I found that NuCalgon's Easy Seal uses 2 oz of a hyrocarbon as a propellant, so it may result in a failed recovered refrigerant ID test.

BTW...Cliplight's Superseal doesn't use a propellant.

r22a is explosive I don't think I would use that on anything.

You're twisting my meaning.

Pot = Kettle

Enjoying being on the other end this time...

Will the manufacturer warrantee the compressor with that replacement refrigerant?

Not sure if they care though, they don't even want them back any more. Just give them the Serial # and they get you a new one.

Topping off as in mixing the refrigerant? Hell I've never knew of any refrigerant we could mix in the field but some of the old dogs may know otherwise.

Manufacturers said not to top 12 with hot shot. Been doing it for years with no problems. Have not used any of the 22 alts but as soon as the boss buys me a jug I'm gonna try it on my old package unit. They us a different oil but if it ducked it up I can scrap it so its win win.

Yeah, it's a win/win for you, since you don't give a crap about rules or laws or correct procedure or anything. As mentioned earlier, though, it is not a win for that guy that follows behind you and gets to pay the charge for turning in the garbage mixture that you created.

Im going to be using dupont iceon mo99 (R438A) for retrofitting systems that have mineral oil. It has the lowest capacity loss of all of them aprox 5 to 10%. I will also be buying United refrigerations own private brand Thermal Zone condensing units, which is basiclly a rheem product. They are offering those units with polyoester oil. So I can then use R407c as my refrigerant. It is the closest to R22 with the least capacity loss.

Also what will be the going rate this season for R22?
We will be charging $70.00 per pound.

let me see if I have this right ,the 22 manufacturers probably are selling 22 jugs to dist for maybe 250 the dist sell it to us for about 500 we sell a jug to our customers for about 2000,wow no wonder nobody trusts us.

POE oil is compatible with all refrigerants, so you should be ok there.

I am looking for a cheaper alternative as well. I just have a problem with paying 4 or 5 hundred bucks for a cylinder of R-22. As far as selling new R-410 units goes. We've been doing that as well, But we've had a fairly large call back rate on those units. Mostly all leaks and when we finally find them they usually wind up being the evap coil. It does seem fairly limited to package units for some reason though. We put a new gas pack in for a lady about this time of year in 2010. It didn't even make it through the first season before we were back out there looking for a leak. Finally found the leak and replaced the evap coil under warranty in the fall of 2011. We had to go back out there a couple of weeks ago and charge it up again. She's probably got over $1000.00 just in labor and gas since we installed it. How are we supposed to sell that to a widow on a fixed income?

Should'a gone in on a few skids of 22 a couple years back...but some guys were just hoping the phase out would go away and the price would come down.

Now everybody is paying the price.
