The salesman, Paul Nicholson, was very professional, knowledgeable, and helpful with setting everything up and helping us pick out what was right for what we needed. The windows are the right price for the quality of product and professionalism we received. They came out again before Installation to double check measurements and know exactly what had to be done. We used Illinois energy twice, and both times the group of gentlemen that did the Installation definitely exceeded our expectations. They were quick, cleaned up after themselves, taught us how to use them, friendly, and communicated their time arrival and met they time window. I would absolutely recommend Illinois energy!
