“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'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-.”

“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 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.”

Review by

“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.”

Review by

“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.”

Review by
02/16/2018

“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+.”

Review by
02/16/2018

“It was a mixed experience. They were putting in insulation in the back of my house and sort of filling in two windows. I would give the overall experience a C. I don't have enough expertise to judge whether or not they were doing the right thing.”

Review by

“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.”

“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.”

Review by

“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.”

Review by
10/04/2017

“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.”

“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-.”

“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 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.”

Review by

“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.”

Review by

“We haven’t seen any improvement in our energy. They did both the energy auditing and some insulation work. I would give my overall experience a C.”

Review by

“They were just very attentive and very detailed. I met with a lot of efficiency experts or insulation experts, and they were easily the best. They did insulation work and then they helped out with follow-up. They did a follow-up check. I’d give them an A rating.”

Review by

“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.”

Review by
06/15/2016

“The work was really good. The test results at the end of the work was high and good. They did a bunch of weather proofing. They did sealing, like the joints and lots of insulation. There was lots of sealing. I’d give them an A+.”

Review by
06/15/2016

“They came on time, and they were very clear about what it was going to cost. They filed the paperwork to get our rebates. They did an energy audit, and they did weatherization. I’d give Energy Efficiency Experts an A.”

Review by
06/15/2016

“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.”

Review by
06/15/2016

“It was great, and I liked everything about their service. The thing that stood out for me was their efficiency. The two young men were wonderful; they did everything. One went up into my attic and gave me a report of that. I was very, very satisfied. Energy Efficiency Experts earned an A.”

Review by
06/15/2016

“They’re professional. The people of Energy Efficiency Experts kept us informed at all times, every step of the way. They were trying to improve the thermal retention of the house, the insulation. They provided some additional insulation work for me. I’d rate them as an A+.”

Review by
06/15/2016

“They were definitely an A+. They did an energy audit and insulation work for me. A number of things stood out for me. The audit was very thorough, more thorough than I had expected. It was impressive to me that they handled all of the papers involved in getting rebates and so forth. They installed energy efficient light bulbs and shower heads under a Maryland tax program that I was not even aware of. The report that they gave me from the energy audit was specific and very detailed. Their overall approach to the work was highly professional, and I had the general impression that they were not trying to sell me anything. They were just there doing an audit and then making specific recommendations based just on the results of the audit. Those were some of the things that stood out.”

Review by
06/15/2016

“I definitely had a positive experience with them. They were punctual, and they did everything that they said they wanted to do. They explained everything in very good detail—exactly what they were doing. When we did the study and saw the result, they explained to me what needed to be done and the ways to go about that. They were just overall very good and were responsive. In addition to the audit, they also did some insulation work for me. I’d rate them as an A+. I can honestly say I noticed the difference after they did the work; the next winter, my house just felt warmer. I have recommended them other people to utilize them.”

Review by
06/15/2016

“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, 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. I’d give them a B+.”

Review by
06/15/2016

“I liked everything about their service. They were knowledgeable and cooperative. It was a little expensive, but probably not more expensive than anybody else. It was just sort of an expensive operation that we had going on here. They were responsive, neat, and I felt good about it. I’d give them an A. It was both energy auditing and insulation work.”

Review by
06/09/2016

“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. I’d give them an A-.”

Review by

“They were great. They were honest, they told me they could save me money on my electric bill and heating, and they did. They did both energy audit and insulation work. I’d say Energy Efficiency Experts deserve an A+.”

Review by
06/06/2016

“They just came out quickly, did the work quickly, and produced a good report. They also did some insulation work for me. I’d give them an A grade. They had a contractor come out, and they took care of all of that. They were here when the insulation work was being done.”

Review by
06/06/2016

“The number one thing that I liked was that they were very thorough. I guess that should come with an energy audit, but these guys were very thorough to the level that I was impressed. They did an energy audit and insulation. I’d give them A; I was very satisfied.”

Review by

“I was pleased with the work that they did. I thought that the cost was appropriate, but there is a lingering problem that I have had since they were there. That is that for some reason, my basement has gotten very, very cold in the wintertime, and they could not explain it. Right now it’s not a problem because we’re in hot weather, but I have no idea what the heck this is going to cost me to try to remedy this problem, which I lay at their doorstep. My experience with them is positive in one respect and very negative in another. If anything, I’d give them a C, but that does not cover both extremes. The insulation that was done, the work on the windows was fine, but they did something that upset the balance of delivery of warm air to my basement. If anything, I’d have to give them a C, maybe worse. I like the people, and they were responsive when I raised this issue but basically threw up their hands and said they didn’t know how to deal with it. So, I’m stuck with it. They don’t live there, I do. They knew what they were doing when they put the stuff in, but they don’t know what it is that is causing the lack of heat in the basement.”

Review by
06/06/2016

“They were very concrete about what they could do, and they did it. My house is more consistently heated, and I’m not having to run the air conditioner as much. They did a lot of insulation for me. I would give them an A. I assume the work was really good. They were very punctual, and they seemed both knowledgeable and clean. I’ve already recommended them.”

Review by

“One issue is that they had to pull out my dish washer to get behind it, and they crushed the tubing when they put it back in, so I ended up having a dishwasher leak. They caused my dishwasher to have a problem that required service which, of course, I didn’t figure out until way later. I liked that they accomplished what I hoped to be accomplished. It was insulation work. I’d give them A rating.”

Review by
06/06/2016

“I liked their timeliness and their guidance on specific efficiency recommendations. They were professional, and they knew what they were talking about. The goal was to reduce the amount of airflow out of the house, and they definitely achieved that. They did both auditing and insulation work. I’d grade them as an A-. I really didn’t have any issues with customer service, but we had some back and forth and there was some miscommunication on a few things that we had to clarify. It wasn’t overall negative, but there were some things we had to clarify. Customer service was a little bit lacking, but it wasn’t horrible.”

Review by
06/06/2016

“I liked Energy Efficiency Experts finding out what needed to be done to my house, but the one who actually came out, and someone has already come to do the follow-up—I didn’t like her attitude. It was like I didn’t have a big house and I wouldn’t have the money to take care of it, so I would definitely never use her again or recommend her to anyone. It was both energy auditing and insulation work. I would say I had slight issues. The quality of work was good, and they were very thorough. The woman that was actually doing the work was very thorough.”

Review by
06/06/2016

“They are very good and very efficient. They do what they say they will do and deliver. The people are very friendly, nice, thorough, and professional. The energy audit they did said we needed better insulation, so they did that. They said we would be refunded, so they did all the paperwork and we got the rebate back in a few months. I think they’re pretty honest. They also recommended an air conditioner company for us, and they turned out to be one of the best. I’d grade them as an A+. I have recommended them to many people.”

Review by
06/06/2016

“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.”

Review by
06/06/2016

“The owner is easy to talk with and very personable. She really brought a lot of integrity and went out of her way to explain exactly what they were going to do and why. When I got the results of the auditing, she was able to really explain it in a way that I understood just what was going on with my house. She then provided me with solutions for dealing with it. They did both audit and insulation work for me. They get an A+ from me.”
