“First, timely response by the service technician. Jonathan, (the technician) was courteous and knowledgeable. Easily diagnosed the problem (a mechanical issue) and had unit working within a short time period. Finally, extremely pleased with a fast and accurate diagnosis, providing an explanation regarding the problem, and having the unit back on-line. Would request Jonathan again as the service technician should I need servicing/maintenance in the future. I give him 5 Stars. Thanks again, G”
