Durron at Onnit, LLC, gave outstanding service during his inspection of my initial problem, and also suggested some improvements to my HVAC heating system to help prevent further failure. His pricing was fair, and he was very patient and informative of what exactly he was doing/suggesting, and why. Will use him again for any future HVAC needs.
