Fast shipping. Good products .
Not cheap refrigerant.. only DuPont freon recipe from what I can tell.
I'm licensed HVAC R technician and every customer including myself . I've used these products .. work flawlessly but don't overcharge system. Have technician install or check for leaks before installing.
Lots of people don't realize but the rubber o rings on Schrader valve fill port goes bad . So you'll eventually lose refer or burn out compressor. I recommend leak check . Cleaning coils .. and new valves .
Full vacuum test . Then charge system to vehicle specs . Usually between 12 and 20 oz ... . One 12 oz can will get AC going but better to have proper 16 oz charge . If needed? .... Do not vent or release into atmosphere by EPA guidelines. And use proper tools and PPE...
But you can't beat these products , or price from this company.. quality top notch refer , non recycled... I'm guessing.
