HOMEOWNER REVIEWS

“Overall they seemed good. They were the most expensive quote and I was expecting top level service. The sales process was convincing (they fully mapped out the attic and used a heat camera to show me hot spots, etc.). The work crew were professional, respectful and on time (only problem is their truck scratched into my driveway and left a small hole). Where I think they fell short was the lack of follow up. I went with them because of the warranty and the flashy sales process. I was hoping they would come back after the installation and checked again with the heat camera.”

“Team lead and workers”

Review by

“I would like to thank John LeVan for his committed involvement in making sure that I was fully satisfied with the attic insulation Comfenergy installed at my house. They had initially installed cellulose in my attic, but I immediately detected a heavy, musky odor that permeated my entire house. John and I worked together to try to identify what could be causing the odor. He was wonderful to work with as he patiently answered my many phone calls and questions about how to resolve the issue. He provided superior customer service to try to identify the source of the odor that apparently only I could detect he even called in a representative from the manufacturer who took a sample of the cellulose for testing. There was nothing wrong with it, so in the end, we collectively agreed that I am allergic to cellulose or I am simply acutely sensitive to the product. After more discussion, Comfenergy removed the cellulose and installed Rockwool insulation instead, which resulted in the odor promptly disappearing! Throughout this several month process, I could tell that John wanted to make sure that I was 100% happy at all times. We spoke many, many times throughout the course of the project and he paid very close attention to my satisfaction to ensure that I was happy with all aspects of their work and the insulation. I am very appreciative to have had such a great person to work with and, as a result, I do not hesitate to fully recommend Comfenergy!”

“John for his attention to all of our needs. He went above and beyond for our family to make sure everything was done right so we won't have any future issues. Shayne for his initial diagnosis and testing, as well as his scheduling and work behind the scenes. Pablo (and crew) for all of the framing, drywall, painting and finishing. Really great working with them to get our desired outcome.”

“I chose Comfenergy after doing some research and also on the recommendation of a family member who had used the company. I was very pleased with the work they did in my attic last year and employed them again this year for work in the basement of my home. I found them to be informative, professional, and easy to work with.”

Review by

“They were very thorough in their initial quote. They provided evidence of the kind of work that we needed. They explained everything very clearly. They installed some insulation, as well as a new fan in our bathroom. I'd rate it an A. Their quality of work was great. We have really good quality insulation that's clean. We don’t have all the fluff going all over the place that you have with you know, the traditional insulation and our basement has been much warmer.”

Review by
10/24/2017

“They were in and out quickly and they did the job that they said they were going to do. It went fine. They insulated an exterior room in our house. It was a full insulation, not your typical insulation. An A is fine.”

Review by

“Comfenergy provided the service that they bid for within the budget that we had agreed. They were careful and they were quite professional. They put insulation in the attic. I'd rate the experience with an A.”

Review by
10/05/2017

“He was easy to get a hold of, and we did a lot of communication back and forth so I think communication was a plus. We had some heating discrepancy between the rooms, so they did some insulation and venting. I would give an A-. It was a tough problem. It wasn't something we were expecting a quick fix.”

Review by
10/05/2017

“I think the way they did the work and their customer service when they're here was positive. They cleaned up well after themselves, and they just got the job done when they said they would. They put in insulation in the attic area. I'd give them an A.”

Review by
10/05/2017

“It was very good. They did everything they said they were going to do. They were informative, and they handled themselves professionally, great deal of help. They used foam insulation. It was A+. They did everything they said they were going to do.”

Review by
10/05/2017

“Just the salesman and then the workers made it positive. They always kept me up to date on what was happening and got the job done pretty quickly. The most thing that I really noticed was the lack of water under my house. That was what I was really concerned about. The insulation, I really didn't notice because that is in my kitchen. I have tile floors and it just absorbs the cold anyway. My big thing was dehumidifying underneath and the two sump pumps they put in. I give them an A. The insulation experience, I do know that it has taken a lot of the dampness out of the house, inside the house and all. I have no complaints at all. A across the board.”

Review by
10/05/2017

“I did have my roofing and siding done. I'm not sure if it was the contractor that did the insulation, but if it was part of that then that whole experience was positive. Of course, my roofing got taken care of. It got damaged in the storm and my siding got damaged also. So all in all, I'm happy with the work that was done to the house. If it's the insulation, I would say A. I didn't have any issues with the insulation.”

Review by
10/05/2017

“They did their work quickly and did a very good job and all of the interactions with everybody was very good. They did some insulation repair because there were certain parts of the house that weren't insulated. I would give them an A. They didn't step into the house. They did everything outside and they cleaned up after themselves. It was almost like they were barely there. They were very knowledgeable.”

Review by
10/05/2017

“They did insulation in the attic. Their professionalism made it positive. I have noticed a difference in the comfort of my home and energy bills since it was completed. I'd rate it an A.”
