ok. Please don't flame me. My test system is one that I own and it's a ancient POS. I don't mind blowing up a compressor or trashing it.

The system is from the 1980's and used capillary tubes for regulation and is 2 ton. The condenser is way way under sized and placed on top of the unit so Hail could tear the hell out of it.

I have replaced the horizontal A coil with a 2-3 ton York unit and setup a R22 TXV. I just saw a cool 2 ton R410a condenser on craigs list for a easy $150 that looks new. The 410a system has a way over sized condenser for high efficiency. I may put that one in ..

My plan is to mate this to the A coil, Install a dryer/filter and let her rip. Will perform the usual sub cooling charge and tweak the TXV after it has settled in.

I have been using BBQ gas for a while now and I must say it works great! I use driers because I don't know how pure it is but I am very impressed so far. Got a adapter on E-bay so I could hook my gauges to it.

Thoughts?
