Jim taught me more about my home, energy use and current systems in a few hours than I've learned in the 17+ years I've been in this house!

One of the nicest people you'll ever meet.
He sold me on GSM!
Where I'm losing the most heat/air and simple ways it can (and could have been) be fixed. I'll have them back for more work to make my home more energy efficient.
