We bought our house three years ago, and the tech, Hunter, not only remembers issues between visits, he knew our equipment from the previous owners and could answer our questions about the history of the system. He’s also patiently walked us through the things we can do for ourselves between maintenance visits. We also had a great conversation about our dogs and where we buy locally raised meat while he worked, but that may happen because I’m pretty chatty! He’s professional, on time, and personable, and I know that our heating and cooling system is in good hands. Knoechel does a good job and Hunter is a treasure.
