“They were fantastic. When Pascale came out, she did a great job of explaining everything that was going on in the house. It wasn't a hard sell at all. The installers did a great job. They were on time. They left the house cleaner than they found it. In the end, everything has been more comfortable since they finished their work. They did an energy audit, some insulation, and some other repair work. I'd give Energy Efficiency Experts an A+.”

“They did a thorough review of the energy used at my home in the spring. They did a good job. They did the energy audit, and then later, some work on the insulation in the attic. There were no problems—excellent.”

“They were very good, very thorough, and they followed up with the report and pressure studies. And they were very, very good. I had the insulation done after the fact. So, I kind of put the cart before the horse. I would give them the best. They were very thorough, and they came back twice to follow up. So, they were very good.”

“I liked that they were very social. Very pleasant and they smiled. Whenever I asked a question, they didn't dismiss me—they answered my question and basically said, 'we get a lot of questions like that.' They started with the audit, and then I had them do some of the insulation. I'd give them an A+. They kept in contact with me the whole time. I would recommend them.”

“There was nothing that I disliked. They really knew their stuff. They were really easy to work with and very professional. They also did the work. They gave the audit, recommendations, and then we picked what we wanted to do, and they did it. I would give them an A+.”

“Overall, it was a really good experience. It was efficient. They were responsive. They did what they said, which is—we got a rebate back from our energy company, based on the work that they did and that was as they had—it was basically what they said it would be, so that was positive. The only thing that was a little difficult, and this wasn't really their fault was that we were doing roofing work with another company, and we had to coordinate between the two, and that was difficult. But it wasn't really their fault, as much as maybe the other company's miscommunication. I was happy with their services. Everybody was polite, courteous, efficient. They did an audit, and then based on the audit we did—sort of most of the itemized list that they had found on the audit—so there was some insulation work. I'd give Energy Efficiency Experts an A.”

“They came when they said they would come, which is always nice, and they did good work. They did insulation on my attic, and I've just had some guests staying up there, and it's been warm—for Washington, DC—and they said it was pleasant there. The temperature was pleasant and not overly hot on the third floor, which is usually pretty hot without the insulation. They cleaned up well afterward. I think they did a good job. They insulated my whole attic of my townhouse. I would give them an A. They did good work, and I had no complaints.”

“They did an audit at our house. She was easy to work with, very responsive. They did insulation and an energy audit. Overall, I would give them an A.”

“They were on time. It was good. They came in and did the efficiency check for our home. They did the insulation on the roof. I'll give them an A.”

“They were professional. They were on time. Energy Efficiency Experts just did a professional job. They did insulation work. I'd give it an A.”

“They were very diligent and preserved in finding everyway they could to fill places where outside air could get into the house. They did insulation. I would give the experience an A.”

“Pascal, the owner, was really easy to work with. They were pretty flexible with their scheduling, and I shopped around for comparable rates, and they had the lowest quote. They added insulation to my attic and sealed some air openings to the attic that air was seeping through. They contracted out a company to clean my air ducts and to seal them. I would give them an A-.”

“The staff were all good, thoughtful. I felt like Energy Efficiency Experts knew their material and were experts. They were pretty responsive. They did the audit, and later on, they did the insulation and sealing. I'd give them an A-. There was a little bit of extra clean up that they could have done.”

“They're pretty clear on what they're going to do. I needed extra work they couldn't do, and they helped me find someone to do it. They didn't fix all the issues because—just the way house is built there were issues they couldn't fix, but other than that they showed me the other issues and told me who to call to help fix those issues. We've been pretty happy with what they've done. They did energy audits and insulation, and the Pep-Co rebate thing. I'd give Energy Efficiency Experts an A-.”

“It was fine; nothing stands out. It was done, and that's great. They did insulation, I would grade them an A+. They have finished it, but it's insulation—I have to wait 'til Winter goes by to find out if my cost could have been reduced.”

“They did a very good job. Their estimate came in accurate, and their efficiency was quite high—they finished the work quickly. And when we noticed things we weren't sure about, they answered all our questions immediately. They did wind up doing a fair amount of insulation. I think the total cost was like $9000. I'd give them an A+ overall. I would recommend Energy Efficiency Experts.”

“Energy Efficiency Experts was definitely an A+. They did an energy audit and insulation work. They were very thorough—it was impressive to me. The report that they gave me was specific and very detailed, and their overall approach to the work was highly professional.”

“They were fantastic. I've already recommended them to my neighbors, and they've used them. They did insulation and an audit for me. I would give Energy Efficiency Experts an A+ rating.”

“They were very knowledgeable and worked with my schedule well. They did a good job as far as I know. They did attic insulation and put an exhaust fan on the roof. I'd give them an A grade.”

“They did what they said they were going to do. They were very pleasant to work with, and what they did is working very well. They did a bunch of insulation work and some venting.”

“They were very good. They were very pleasant and efficient. They got the work done in a short amount of time. I have no complaints. They just did insulation for me. I'd rate them as an A.”

“They came to install an attic fan. A few months ago, they did the audit and insulation work. I'd rate them as an A. The work they did was in the attic, and they said they would take pictures. I didn't actually get pictures that showed a clear image of everything they did, but I trust them. They did a great job. I can't imagine that they did a poor job. I'm waiting for customer service to answer one question that I had, and it's been a week. They were right on time. I would definitely recommend Energy Efficiency Experts.”

“They explained what they were going to do and why they were doing it, so I felt I had a pretty good understanding of what we were looking for. They did both energy audit and insulation work. They deserve an A. The work seems pretty good. They were very positive, and they were punctual. I had no problems.”

“As I recall, they were prompt and clean. They did the work that was in the contract. They did both energy audit and insulation work for me. They were fine.”

“Energy Efficiency Experts were just no fuss, no muss. They just knew their stuff. They weren't trying to sell me anything; they were just giving me the facts. They did an assessment and home energy audit, and then they recommended improvements to decrease our energy consumption. And then, I believe using subcontractors, they performed the work. They did insulation for me as well.”
