I got my 609 certificate and warming up to the idea of fixing the AC of my 83 SD. I'd like to get some quality tools at resonable cost. Here are a few that I'm considering:

R12/R134 manifold gage:

CPS MA1234 dual R-12/R134 manifold gage, cost $123
Robinair 48450 dual manifold gage, cost $107
http://thetoolwarehouse.net/shop/TTW220.html

Vaccum pump:

FJC 2.5 CFM 2 stage, cost $122
Robinair 15434 4 CFM 2 stage, cost $204

Any recomandations? TIA

This is the vacuum pump I own:

I'm not saying the other ones aren't any good or this one is better. All I know is it works great on cars. If you want something that will work on a home AC system you probably want some more CFM. Depending on size I would say a 4 cfm would do for just about any residential unit.

As far as gauges that gauge set is fine. You don't need the most expensive one. Sometimes simpler is better.

I'm only likely to use it a couple times so it should serve its purpose.......

I personally would never use a dual set. You should not contaminate a 134 system with 12 refrigerant and oil and vice versa.

A 2 stage vacuum pump is the way to go.

Your best bet would be to get Jims recovery machine. Having a recovery machine is THE way to go IMHO.

R12 is down in price now, so you can keep your SD on the good stuff for very little more money these days.

Have a great day,

Well I need to find the problem in my W123 A/C and fix it....and I want to retrofit my W116 back to R12.....per a label it has R134 in it now....and in the heat of summer its just barely able to do its job.
