"Everyone I worked with, David, Julien and Mike were extremely professional. Knowledgeable and explained e everything they were doing and why. They cut the energy loss in my home by more than half. I live in a 96 yr old home. I had no idea how much outside air/heat/cold was getting into my home and thus making my energy bills higher than they should be. Thank you to the team for everything!"

"I highly recommend Lumeco Energy. They did my home energy audit and gave me some good recommendations. We chose to air seal our attic and add more insulation. They were able to get me some rebates from BGE so the pricing was discounted."

"Mohammed handled our project—sealing and insulating our attic. He was very knowledgeable about the best way to accomplish the task in an older home such as ours; and he also ensured that our project qualified for relevant energy rebates. He was professional and courteous in answering all our questions and completed the project in one day. We highly recommend HESS and Mohammed El-Goul."

"Atlas Home Energy performed an energy audit in my home, and based on the findings corrected all issues over a four day course.
