Very dishonest business! I needed only 4 pounds of refrigerant and my leak soldered on my system that is only 18 months old. It took Frosty Air three days to even come to my house, and after a misdiagnosis the first time around, I was charged after four days without AC for his mistake and the depletion of all the refrigerant. NINE HUNDRED DOLLARS later, I still haven't received an invoice for the second day of work although I've called three times. This guy is a scammer!!!
