A/C Masters Heating & Air Conditioning Inc. had previously done a service call for me so I decided to use them again. This time I had them repair a condenser coil and a piston that was in the air conditioning unit. The technician seemed to be very knowledgeable. I felt that the pricing was a little bit high but I guess that is to be expected for this type of work. The job turned out just fine and seems to be working satisfactorily. I would recommend A/C Masters Heating & Air Conditioning Inc. to others and plan on using them again when I need to.
