It's 14 degrees outside and balmy inside our house now. I am tempted to wear a Hawaiian shirt and pair of shorts. Really, it's quite a change from before. The house is much more evenly heated across rooms and across floors, we don't feel the drafts anymore or see our breath in the closets, and the furnace seems like it hardly cycles on anymore. Really impressive job by you and your team. We can't get over what a difference it has made - thanks!
