The service was exemplary. Christian knocked on the door, but prior to that acknowledged that he was going to be 15 minutes prior to arrival, which he was exactly on time. He was very informative, and even though I was working from home, he had minimal noise while doing his task, he was also very informative informing me that I had a part that needed repair quickly. Found the estimate for said part and let me know all of the options that were available to me. We definitely will use Robinaire when it comes time to replace our furnace.
