"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."

"Have a problem with cold basement and hired Home Energy Saving Solutions, LLC to do home energy audit. Energy consultant Mohammed El-Ghoul came on time and after short inspection suggested that we do need more specific HVAC audit, not whole home energy audit. Mohammed suggested a company which can do this, also made some very useful suggestions, and checked couple of things for free. We were not charged for service despite fact that Mohammed spent almost an hour at our home and provided useful advices. Very professional and honest service and I strongly recommend Home Energy Saving Solutions, LLC and especially energy consultant Mohammed El-Ghoul!"
