"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."

"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."

"Great. The energy audit identified the source of the humidity infiltration. And the audit report identified adjustments needed to the exhaust fan."

"This probably the most professional service organization I've worked with in any capacity. They did a comprehensive audit and we discussed issues that could be remediated prioritized by the biggest bang for the buck and then they did the fixes we agreed upon. I always felt like I was dealing with an expert who had my best interests at heart - work that they could have done that they advised could be deferred. Ended up increasing the insulation in the attic which I'd known for years was a problem and sealing the ducts which has made a noticeable difference. I'd happily recommend Atlas to anyone who thinks they might benefit from a home energy audit and efficiency upgrades."
