    Customer Testimonial

    Michael F.
    Pawleys Island, SC
    This homeowner from Maryland has been completing some home improvement jobs throughout their home. They decided to convert their garage into a second living space for when their family comes to visit, to include a new double sided fireplace. To insure the conversions comfort, the home owner had new blown in attic insulation installed, along with an insulated attic hatch. We also placed fiberglass wall batts before the sheetrock was completed. His video testimony was a treat because as a business owner himself, he was blown away by our appointment center. "Jill's kindness really did set the mode of our whole experience!"

    I am very satisfied with your company, from the sales rep to the installers. Everyone was very professional and thorough. Another thing that was very professional was the follow up from the sales rep and his supervisor. I would recommend your company to anyone that needed a new unit or repair of their own existing unit.
