I’d scheduled my annual furnace clean and check for 8 this morning and got a call a few minutes prior from dispatch advising me that the tech who was to come over was out sick and they were reassigning the job to another technician in the area to come over as soon as he completed his current job. He was at my house by 9:30 and did a great job. I appreciated the heads up from the dispatch center too. Glad to be a Black Diamond customer.
