I have nothing but great things to say about the service GAC performed. From the service tech, to the quotes for a replacement system, to the installer, everyone I dealt with was a consummate professional who took the time to explain my options and what would need to be done. The price to replace my AC system was reasonable and the work was done in a timely manner.
