I called on a Wed afternoon and booked the first available appointment - Fri a.m. Was called Thu morning and offered a cancellation slot later Thu morning, which I really appreciated (snow in the forecast Thu eve ... might have cooled off inside.) Received a call around 30 min before Seth arrived. Seth was right on time, and was very professional and pleasant. He was able to restart the furnace almost immediately, but he still took the time to check for any possible sources of the failure, and he patiently explained a lot to me about how the unit functioned. While he wasn't able to discover why the furnace quit working, I felt confident he'd done a thorough check. He also took the time to talk to me about my concerns about a whole-house humidifier that had been installed by the another service provider. I would not hesitate to work with Westin, or Seth, in the future.
