76 Scamp A/C

I stated doing auto A/C back in the late 60's early 70's. Then I branched out into residential and commercial/industrial A/C & R. I also still do R-12 systems. I can also rebuild most hose assemblies. I am certified in both 609 and 608. Have worked on everything from little under the counter refrigerators to multiple hundred ton industrial chillers. But I am cutting back on the work. The newer cars have the A/C systems controls tied in with the ECM, and it is just too expensive to upgrade my diagnostic equipment, to use on a part time basis, and now that R134a is going to be phased out for 1234yf, that will mean buying all new equipment, again. So, I will just stay with the older cars, untill I put my tools away.
