Report
Jason executed the repair of my HVAC system failure with superb logic. Being a well-trained and astute technician, he began by inspecting the numerous wire connections accessible in the air handler compartment, and immediately discovered a problem with a pin & socket connector. Although this was obviously the failure point, Jason took the time to jump onto the roof (Jasons humor) to complete a thorough inspection of the condenser unit of the split-system. The first-class services I received were much appreciated, and a reasonable service charge was the extent of my expenditure.

Report
AC unit went down last night. We have a home warranty and made a service request. The assigned vendor called and said the earliest he could get here was next week. Hey, it's only the desert in July right? Called LJ Refrigeration and they dispatched Jason that same afternoon -- very knowledgable, professional, friendly. Repaired my unit at what I considered a very fair price. Can't thank them enough. Excellent service. They are outstanding!
