It is now to hot outside to drive my black V8 around anymore. My a/c turns on but will not hold a charge. I have tried leak detector and stopper but I never find where it is leaking and it only holds the charge for about 3days.

Can anyone recommend a shop to take my car to? Im hoping its just something like a hose leaking. But if they can find it and fix it.. great... less work I have to do... LMK. Thanks....
