CD Shanahan quickly responded to my air conditioner failure to diagnose, order parts and install. I extremely pleased with the technician’s who diagnosed the problem and then remove and replaced the failed compressor. The technician’s were extremely professional and pleasant during all phases of the repair process. The customer representative was pleasant and responsive each timeI called. I am very happy with all aspects of interaction and service from CD Shanahan company and highly recommend them to anyone who needs service.Posted on Google![]()
