"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."

"I had a full house evaluation. Elite Thermal was able to use that to get me a significant discount. They came and did the service in in one day and then returned a few weeks afterwards to find tune and the leaks that were identified on the follow up blower test. They changed the wrong exhaust fan and then did the right one at no additional charge. I would definitely work with them again. Actually, they have done an evaluation and an estimate on my second home and I expect to have them start soon."

"Arrived timely. Finished work quickly. Left behind trash. Recommended a unit that was larger than my ductwork could handle, although they alleviated the issue by adding extra returns."

"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."
