Can't seem to find anyone to service my a/c with R-12 in the Greater Toronto area. They tell me it is now "illegal". Is R-12 still available in the US? If so, can someone suggest a competent & honest shop that will not take my arm off for R-12 service (preferably less than $50/lb)? I would prefer NOT to convert to R-134a.

My vehicle is a 1992 300E. a/c works fine except takes longer to cool. I think it just needs a recharge / topup.

US cities I can access easily and would be willing to drive up to 1 hr from these points...
Buffalo, NY
Pt.Huron / Flint / Saginaw, MI
Toledo, OH
South Bend, IN
Boston, MA
Dallas / Ft.Worth, TX

Thanks in advance,
