"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. 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"

"Brian came out to perform an energy audit on my home. He arrived on time, was respectful of my home and showed me where my insulation was missing with his infrared camera! His report came two days later as promised with a reasonable quote."

"Wonderful, it was a very quick and easy process. Brian talked us through it and in no time we had a 3KW system mounted on a frame in the garden and the invertor installed in the basement. Brian talked us through working with our power company to get the system checked and approved and we now get credits from the power company for power we provide to the grid. In addition we are set up to get Solar Renewable Energy Credits (SRECs) payments for providing clean energy. We also got a free Energy Audit which helped locate some problems areas we were able to fix. The system has basically cut our energy costs in half. I have hesitation in recommending them to anyone interested in solar energy."
