When I had an issue with my Sub-Zero refrigerator in San Diego displaying an 'EC 20' error code, I contacted Deluxe Appliance Repair, and I couldn't be happier with the service I received. The technician arrived on time, was very courteous, and quickly diagnosed and repaired the problem. He also provided me with some useful tips on how to prevent similar issues from happening in the future. Overall, I was very satisfied with the service, and I would definitely use them again!
