Window motor and repair A/C

I received quotes for both repairs: $143.00 and $1200.00 to replace A/C compressor. We had received quotes for the A/C at 2 other companies. To my surprise, John called to say there wasn't a problem with my window! They had repeatedly opened and closed the window without it sticking. He told me he could replace the motor if wanted him to, but there wasn't a reason to. Later that day, John called once again. The A/C Freon was very low! He filled the freon and I drove away with an $80.00 bill. Furthermore, John told me if the A/C stopped working within the next 2 weeks, he would replace the compressor and deduct the $80.00 from the bill. How's that!! An honest and trustworthy mechanic!! Thank you John and all the great people at AMERICAN MALL AUTO!! Sam & Kathy Pettigrew
