    I had a great experience from Brenda and her crew at Comfenergy to fix a problem that has been in my attic for many years. My townhome is in Leesburg, VA and the air handler is high up in the attic, so every time it is hot and humid outside, the AC cool air forms condensation outside of the ducts and then drips down three flights to the basement, pools on the drywall and ceilings, that led to rot and mold. Comfenergy explained and educated me in full detail how to fix by closing up all the small gaps around the ducts, bathroom and kitchen exhausts, reduce heat in the attic from the roof with a heat barrier, and put in cellulose insulation to fill all areas that help reduce energy bills. I would recommend Brenda and Comfenergy for anyone experiencing a similar problem.

    Cyrus came to quiet a fan that had been recently installed. My wife and I were both very impressed with his problem-solving ability. As he determined, the noise had nothing to do with the fan. He also removed some water from an outside vent which he thought, and correctly so, was causing the noise. He reattached the wallboard to the ceiling when he had finished. The problem has been solved and the fan is quiet again.  Further, Mr. Toby demonstrated excellent interpersonal skills. He was able to explain, in terms we could understand, what he was doing and gave us some choices for solutions along the way.  We will recommend your company to others and certainly come to you first, if we should need your expertise again.

    Good Afternoon Everyone Brent Bevens and Carlos Ramirez did the insulation of our Fireplace today. Yippee!!!! Their friendly Customer Service coupled with their hard work certainly was appreciated. They came around 9:00 and completed the task at 3:30. Before starting they shared pictures to let us know exactly what they were told to do. They worked fantastic as a team to ensure the job was done properly. They ensured the trash was picked up and put in garbage bags while they were working. They walked the yard to ensure everything that was blown by the wind was picked up. HOA cannot complain one bit. We look forward to receiving a telephone call from Brenda to schedule the blow in insulation for the bottom flooring. The inside floor gets extremely cold during the Winter. We truly appreciated the excellent Customer Service and enjoyed having Brent and Carlos taking care of the job. We took pictures of the work and can be assured the air won't be coming in anymore. Hopefully, our heating bill will decrease. Thanks to Comfenergy our home is much more insulated and our utility bills sure have decreased.

    "I wanted to comment on the wonderful job your team did in my home yesterday. Robert, Patty and Danny were all very professional and friendly. They set up quickly and prepped my home to eliminate the potential for damage or making a mess. They worked efficiently and kept in communication with us as needed. We can already feel a difference int he areas of the home that they worked in. I wished we had called Comfenergy sooner than we did. We are recommending the same service to several of our neighbors who have similar concerns in their homes."

    "We had two teams come to our home in Warrenton to update the insulation in our attics and to encapsulate our crawl space. Mayra (team lead) and her crew did a great job removing our old (very old) loose fiberglass insulation and then they fixed improper bathroom vents ducting, air sealed the attic and blew in cellulose deep enough to encase our flex ducts and "can" light covers. The next day the came out and upgraded the insulation in our cantilevered floor (2nd level) using 4" thick insulated foam board. Pedro was the team lead for the encapsulation system. His team was also outstanding. Both Mayra and Pedro took special care to cover floors, put up dust barriers and the clean up was perfect. They explained the process and showed us their teams progress along the way.Within 24 hours we noticed that our HVAC system isn't coming on as often and the house is holding it's heat much longer than before. $$ well spent on this upgrade."

    Our salesperson, Tim, explained what the job would entail, but also the science behind it. He informed me of what I needed to do to improve efficiency while working within my budget. The scheduling department was wonderful! I requested to have my install day moved up if there were any cancellations and they were able to get my project done sooner. The production crew did a great job explaining the process and took great care with my property. I will definitely use Comfenergy again!

    "We had Comfenergy do some closed cell spray foam. Stephen was extremely knowledgeable and a joy to do business with. We originally got a quote last fall and they did a professional job following up. Luckily our project was delayed and we had not made a decision yet. When Stephen saw my original quote with a rep that is no longer there he wanted to come out and see the project again to requote to make sure it was correct. Naturally I was hesitant because I didn’t want it to go up. When he came back he toured the job, asked the right questions and after learning what I was doing he was able to update his recommendations, find adjustments that actually came back with an even better price for more accurate work I needed! Who does that!? Only a company with integrity! We proceeded with the job and it was a great experience from start to finish. They are extremely knowledgeable and responsive to any questions. I highly recommend them and look forward to continuing to do business with them."

Each day she shared pictures of the progress as I was not interested in going into the attic myself! The crew cleaned up before leaving each day and set up quickly each morning. I would highly recommend!"

    Mike was very helpful and explained many details to me as I had forgotten some of the variables since the previous installation and service by Chad, who also had to teach me so I could understand the system he installed and why. They have both demonstrated the needed patience, professionalism and talent not only to do their job, but "to teach" and "to review" with me, those nitty gritty details so it makes sense, from year to year. It takes time to do this and they were both generous with their time. Both very thorough and very careful - and it is much appreciated. Thank you.

    Dear Mr. Tetreault: Your company just completed to projects in our crawl space, a “conditioned crawl space” and a joist repair. I don’t often write letters to a company’s leadership commending their employees. With your company, I will make an exception. Our first contact with your company was with Mohammed Saeed, one of your salespeople. He answered all our questions…and we had a lot of questions. In fact, he made a second visit and amended some of his design based on our concerns. He was able to explain his design as well as the process and was very flexible in working with what we already had in place in our crawl space. The next person I had contact with was Sylvia Gatewood who explained in detail the basics of what would happen and told us exactly how the job was scheduled. I called her many times. She was always polite, efficient and always very prompt in returning my calls. The first crew that showed up was the trenching crew headed by Eric Pass. I’m not sure I’ve ever seen people work as hard as Caleb, Alex, and Eric, all three of them never seemed to stop. Not only that, but Eric seems to know something about EVERYTHING! The next crew was the crawl space crew, Adel, Omar and Mohammed II. These three people were amazing to watch as the ripped out the old insulation and tied it up in huge bundles. Kevin Reis then showed up and had the same crew finish up the job. Keven is exemplary; his standards and his attitude are amazing. Everyone I’ve had contact with has been extremely professional, hard working and really good at communicating. It was refreshing to see not only how the crew members got along with each other but how the different crews seemed to respect the work of the others. I never heard one employee ever criticize the other. They all seemed to just want to do a good job. It really seemed to be that simple……to work hard and make the homeowner happy. In fact, when Kevin was under the house with the second crew, Mohammed [Saeed] came by (to have me sign the papers for the second project). While he was here, he (Mohammed) went under the house and helped them finish up the job. I understood later that Kevin showed him something about insulating the area under the bay windows so Mohammed can incorporate that into his future designs and estimates. I’m sure no company is perfect, but your company has some of the best people I’ve run across with the best work ethic and level of professionalism I’ve just about ever seen. I’m sure no one ever commends you, just your employees, and they deserve their accolades, but corporate culture starts at the top. I admire what you’ve managed to build……….a team, a real team. Thank for the work and for the finished product!!
