They're a wonderful company. I've come across a company like them very seldom in my life. Everything that they did was honest. They did what they said they were going to do, and they did it well. They're an A+ company. I can't say enough good stuff about them. I also met the owner, and he's why that company is the way it is. I certainly would recommend them.
Comfenergy got the work done efficiently. Everything was cleaned up beautifully. They did everything they were contracted to do. I'd give them an A. Their punctuality was fabulous.
I'm very happy with them. They were A+ people—super. I'm so pleased with the customer service.
I'd give Comfenergy a solid A. They were on time and did exactly what they said they were going to do. They did a beautiful job; it looks great. We're very happy.
I remember using them. We had them do some spray insulation in our garage area. We had some issues with freezing pipes above the garage—we had two burst in three years. They came in and confirmed some of our thoughts and concerns about the lack of insulation and the areas where we had issues. They came up with a game plan for how to execute it and correct it, and in a couple of months, they were completed. I would grade them an A+.
They were very responsive. They just put insulation in my attic after we had a pipe freeze—that's supposed to cure that problem. They were just very responsive; if you had a question, they would respond to it and answer right away. They're grade-A.
It was very good. They were one of the only companies that I could find to do the actual work. It was great. We had insulation put under a bay window. He showed us how he did it, and when he came, that's exactly what he did. I would grade them an A.
They were easy to work with, and they were fine. They installed insulation in my walls. My contractor dealt with them mostly, but everything was fine on my end. They get an A.
They were very professional—everyone that was here was professional, and they did a great job. I appreciated everything. They insulated a crawl space that had been giving me problems; it made a huge difference this summer, and I'm hoping it will make a big difference this winter. I would grade them an A.
They did the attic, and they were professional. I would rate them as an A.
