I have all the tools and materials to repair and maintain automotive air conditioning systems.
I’m not going to lie… most automotive technicians don’t know a goddamn thing about refrigeration or air conditioning.
Anyone looking for leak testing, evacuation, charging, diagnosis or anything air conditioning related can get ahold of me.
I have plenty of N2, R12 and R134a in stock. Pricing is VERY fair.
PM for info.
BTW- PJB, You don’t need to retrofit to R-134a. That is a pain in the ass and not worth the effort. They make blended refrigerants that are “drop-in” on R-12 systems and compatible with the mineral-based oils. I have what you need.
