"Absolutely wonderful experience from beginning to end. Mohammed is a true professional. He walked me through the entire energy audit process and answered emails and questions quickly. His team arrived on time, completed the work quickly, and left my house spotless."

"Edge Energy did an energy audit for us, then sealed the house, installed a new roof with excellent insulation, and an ERV fan to ensure fresh air. They were a delight to work with throughout, very friendly and professional. We needed some follow up work due to quirks in the house, not bad work by Edge, and they did it promptly and without charge. I couldn't recommend them more highly."

"Atlas Home Energy performed an energy audit in my home, and based on the findings corrected all issues over a four day course. Their workmanship is flawless and their employees are pleasant and courteous. The bulk of their charge was reimbursed by BGE and my energy cost has declined. I recommend them highly"

"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."
