"Not inexpensive, but worth the cost for energy savings and efficiency. We had received a much higher bid from another company, and were glad we chose Comfenergy. The technician was very knowledgeable and we felt a great difference in our upstair master bed and bath which were uncomfortably warm prior to the improvements. Also nice now to have "green" home for resale."

"I recently had an egress window installed in my home by JDS Home Improvement. I purchased the Rockwell Egress Window. This window brings in a lot of natural light and it's just beautiful! Jordan Jones put a hanger inside the cover of the window so I could hang a plant. Jordan,Joshua Jones and all of the work crew were very professional and kind. The quality of the work is superb. I even had a custom closet made that l am very pleased with. The installation of the window was completed in a few days. The staff cleaned up well. Due to the heavy equipment used,part of my lawn was affected. JDS planted grass seed and the grass has already sprouted in just a few days. If it were not for Jordan, this project would not have been possible. It is without reservation that I highly recommend JDS Home Improvement. I'm looking forward to using JDS Home Improvement for my next project."
