The technician performed the regular service on my heating system. On finding that a couple of vents weren't blowing warm air properly, he carefully traced along the duct system and found that the people who recently insulated my basement ceiling had forgotten to reopen a damper. Good, thorough service.

Also, the technician offered to teach me how to program my thermostat, or program it for me. I had already programmed it myself, but folks, if you haven't, either learn how or have Unique or someone do it for you. You'll reduce your carbon footprint _and_ you'll save money!
