Jerry was very professional, yet casual. I expected him to come in with grand tales of saving me 40% a month on my energy bills and the typical spiel, but instead, his focus was on "here's the problem areas I see, here's what I can do, here's how it may improve." He even entertained other ideas and questions I had and he provided honest feedback on the returns I could expect, and steps I could take to do the work myself to avoid a costly job that wouldn't provide adequate results.
