We needed to have some work done on our sub-zero refrigerator and after reading a couple of reviews from our neighborhood app, we called BBR Service to schedule an appointment.  My call was on a Friday afternoon and I was surprised when David said he could be at our house at 1:00 on Saturday.  He came, determined the issues with our frig, told us what parts needed to be replaced, that he would have them by Thursday, so we scheduled him for that afternoon. He sent me a text Thursday morning to let me know he could be at our  house about an hour earlier if that was ok, which it was. He was very thorough in his work, all our issues were resolved and our sub zero is working like it should.
David is very courteous, service and customer oriented and product knowledgeable; I highly recommend him.
