All my comments here relate to my experience with Allen. Allen is a very knowledgeable technician who ensures that the work he does is accurate and complete. He was patient enough to let me stay in the garage with him and answered all my questions. The company is fortunate to have Allen as a technician. Note in the following ratings, I assume that the cost of labor is not set by Allen, but by the company. Also as a note--when a customer needs a furnace repair in winter, G&S should order parts with overnight or at least 2-day shipping to get heat back to customers as soon as possible.
