This is our second summer since Comfenergy upgraded the attic insulation of our 1999 Cape Cod and we couldn’t be happier! When we purchased this home almost 5 years ago, the second floor temperatures were consistently in the mid 80s and our kids’ bedrooms were very uncomfortable. We replaced the original AC unit and installed an attic fan with no relief. We needed someone to do a thorough inspection and come up with an effective plan, and that’s exactly what Comfenergy did…. -added foam board insulation over existing insulation on the back of the knee walls, blew cellulose in the angles, sealed all cracks and crevices with foam -removed old insulation on the floor of the attic, sealed all floor cracks and crevices with closed cell foam -sprayed closed cell foam on air conditioning ducting that was in the attic. They also found and repaired a section of ducting that had torn and was letting conditioned air out of a gaping hole. -sprayed cellulose over the entirety of the attic floor to meet current standards The upstairs temperatures now hold steady at whatever we set the thermostat to, and we’ve seen a change in our electric bill. It was a thorough, multifaceted approach that has been extremely effective and worth every penny. I ABSOLUTELY recommend Comfenergy!

our second floor during the summer was pretty much an oven. Comfenergy came in, did a great comprehensive check up of our place, and then give us a plan to move forward to fix the issue. There is no pressure, everything was really explained well and easy to understand. We went forward with the work, and now it’s like we have a totally different house. The upstairs is so much cooler and comfortable. And I know we’re gonna see some savings as well in our energy bill. Can’t recommend these guys enough. Carl was great.

Great company, very knowledgeable and friendly and explained everything clearly in a way I easily understood. Provided multiple options and price points and recommendations tailored to my specific use case, Robert was thorough and answered all my questions when doing the estimate. Day of work, Carlos and his crew were fast and on time and protected everything and cleaned up after themselves, couldn't even tell anything was done (aside from the beautiful newly encapsulated attic). 10/10 would work with again and highly recommended!

Scott provided our home with a complete energy audit. Focusing on a plan to remove and replace our existing attic blown in fiberglass insulation with cellulose insulation. Expertly explained the details of removing old insulation, decontaminating both attics, sealing all exposed areas with a sealant and installing new insulation. Answered all my questions and concerns and provided us with the best solution to address our issues. He is a very excellent representative for Comfenergy.

Melvin and his phenomenal team air-sealed and insulated my entire attic assembly - including R60 on both flat and sloped surfaces. The team also encapsulated the duct system and applied a radiant barrier. I am already noticing considerable changes in ambient temperature and air circulation on the top floor, as well as in certain rooms. I also want to thank Jason for the thorough review and discussion of options and for describing the costs and benefits of each solution. I learned a lot in the process. I look forward to further improvements with this team. Thanks again.
