Advanced Air Technologies was utilized to set up a Kaishan Compressor that they are listed as a certified service center for. After the start-up, we immediately began having issues. We brought in Advanced Air twice, and then had a professional come out for a second opinion, it was determined that Advanced Air had improperly wired the machine. The wiring job was unprofessional and the service tech jammed the ring terminals on the ends of wires into contactor ports instead of mounting them properly. This shortcut led to temporary motor failure on the compressor and, according to the professionals who cleaned up Advanced Airs mess, very likely premature failure in the future. This revelation has yet to be acknowledged by Advanced Air Service Manager George, who has argued that they will not warranty their work and that any additional services regarding their failures will be billed to our company. Thanks for nothing Advanced Air.
