Fast turnaround time, I called Monday afternoon and was scheduled for a next day appointment. This was the fall checkup that is included in the service plan, and I really appreciate Luke's help with evaluating my furnace. With a 10 year old system, it was good to get an idea of what I should be looking at doing now, in the next year, and what kinds of non-critical items could help to increase the health of the system and the house as a whole. In addition, Luke helped diagnose a minor issue I'd been having with the system which was very much appreciated. As always, excellent working with you guys, I'd recommend you to anyone!
