I needed an oven thermostat repaired on my pre-1995 Viking range. Ordered the replacement from Viking directly. Paul was the technician from VESCO who came to install the thermostat. AMAZING... maybe was here 15 minutes total! Watched him work. I have been doing home repairs for 50 years and Paul was the fastest repair guy I have ever seen. He obviously knew exactly what he was doing... no standing around trying to figure out what he was going to do. Was cutting wires, removing parts, as fast as anything I have seen. Then he had it back together in no time and tested all the burners and the oven. ALL in 15 minutes. I do not know what else they repair but I would use Paul again in a heartbeat!
