A-Advantage's Testimonials

Friendly technician, courteous and quick service! I needed a routine cleaning on our older HVAC system. I was so relieved to have a technician who did the job without pushing a “new” system even with the age of the HVAC. He carefully explained all the service process and tests performed to make sure our system was working properly. He assured me the “old” system was in great working order. I will use A Advantage again and highly recommend them. Not many HVAC service companies like this who are not also looking to make a big sale.

Tiffany N Valued Customer

I had a minor issue with my HVAC heating unit. They talked me through the issue over the phone at no charge, instead of sending a repairman who would have cost money.  I really value and appreciate A Advantage for their honesty and expertise. If I ever have a serious issue, I would not hesitate to contact this company. Thank you!

Matt K Valued Customer

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.
