A-Advantage’s Testimonials

        Always have been very satisfied with customer service. Keep up the good work !

Karen C. Valued Customer

        Call handler was professional and courteous. Technician showed up same day shortly after I called. Problem was resolved quickly and under warranty. I could not ask for any more. Thanks!

Brian W. Valued Customer

         Thank You, Thank you. Our AC went out on Thursday night and you were able to fit us in for a Friday appt. Your technician narrowed down the problem to the thermostat and then noticed that the Blower motor in the furnace was not working. You worked to get us a new motor by late Friday afternoon. The AC is now working better than before. Your team was courteous and diligent in getting our unit back on line.
