I took advantage of the Angie’s List offer to have IES do an energy audit. They contacted me right away. IES could not have been more professional or helpful and took the time to explain what they were doing. We then discussed different options and picked several that would fit my price range. A quote came right away and a time was set up; he is very responsive to any questions. Miguel and his crew were great. I had attic air sealing done to fill gaps and an attic ladder radiant barrier installed, as well as a water heater jacket and gaskets (weather stripping) for all the windows. I could not be more pleased and would definitely both use IES again and refer friends to them.
