"I did have Davis & Son repair my Heating system and they did a very good job. When I called to have them install a gas line (about 10 feet), they were going to get back to me with a quote and timeline. That was a month ago - nothing. I called and had another firm complete the work in 3 hours. Disappointed that they never called back."
