    I pulled the compressor and sure enough bad valves, when nitro is applied to the high side it blows right out of the suction side.

    I don't have problems with homeowners trying to do things on their own! While I don't encourage it, I'll fix it afterwards! I found a 1.5ton R-22 system pumped up to 500psi this weekend! So instead...

    Such as the plumbing solder? I'll use a 5% or 0% when I can on an R-22 system if there's no danger to overheating valves etc. But sometimes the potential collateral damage warrants the 15%.

    I second this statement! I currently have a 12k single hose and it barely keeps up in a 120sq ft room. It seems like most of it's cooling power is sucked right out the condenser hose.

    I just had an office body spaz out about the cost of 15% silver rods that I order. She could not understand why I can't use the 0% @ $30 vs the 15% @ $210. After a lovely debate about how I've had...

    I used polarbreeze brand bandannas while I was in the Middle East for a year. When heat gets over 120 nothing "fixes" it, but those certainly helped. I usually got about 1-2 weeks of repeated use...

    I'm convinced that Goodman, Trane and Nordyne louvered Condenser covers are the Devil! Today I started cleaning units with a 4 gallon backpack pump and simple green. I only have about 200 left!

    I know of several locations converting over to M099 and they have not had any problems with it. In the next month or so I am going to be starting the change over myself on about 300 units.

    I've used the Ps41-2a in tight spaces and every mm saved comes in handy. The LED lights aren't the best thing ever but they do come in handy while your hands or drill are blocking your light source.

    600k-1.2m is what I've dealt with most. 14m sounds like a bear, I can only imagine having to bleed that system.
