I am writing to express to you my gratitude for the outstanding job that you and your team did in dealing with my home performance upgrade project. When I initially contacted you it was because I my home was drafty, frigid cold in the winter, and blistering hot in the summer. I am happy to report that as a result of your team’s hard work my home is now more comfortable than it has ever been! In addition to the added comfort, I have also already noticed a significant reduction in my energy bills in comparison to this time last year.
