We chose this company based on some coworkers recommendations (I am a licensed realtor of 20 years in this area) and the crew went above and beyond expectations. Final product (new attic insulation) replaced what was most likely original insulation, is now to code for our county and will pass any home inspection. I had quite a lesson on attics from this company and learned a lot during the process. We also want to give a special shout out and thank you to Carlos on the install team. He noticed some electrical items that needed to be addressed in the attic before new insulation went in, otherwise we would not have known. I was able to bring in a licensed electrician to get the work done. Thank you Carlos!!

We contracted with Comfenergy for insulation removal, air-sealing, and new insulation at a historic hotel renovation we are managing while the building remains occupied. Access was difficult and we had to protect finished areas and Guests below. Their crews showed up consistently, worked clean, coordinated with other trades, and stayed on schedule. They installed an attic catwalk system, sealed penetrations properly, and completed the work without disrupting the hotel's operations. We had zero issues during the project and the Owners are extremely satisfied with the results. I would absolutely hire them again for future projects.

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.

We had Comfenergy install new attic insulation and insulate some in our basement. They were very thorough when walking through our home for the estimate. We received a detailed proposal and even steps we could take on our own to make our home more energy efficient. The work crew arrived on time, were friendly and professional, explained everything and showed us the work in progress and once complete. We're pleased with the results, as our home is much more comfortable now.

Plenty of other companies will do the same quality work — don’t use Comfenergy. After signing the contract, communication becomes difficult. Expect to chase them for answers if you have questions. You’ll get passed around a few times before they stop responding altogether. If your project is simple and you don’t need anything after payment, you might be fine, the installers will do the work correctly, but I recommend using someone else.
