Juan Guevara Sorto and his team did a wonderful job sealing our crawlspace. It is truly a night and day result. We are very happy with the service that Comfenergy provided, from initial consultation to job completion.

I highly recommend Comfenergy. Our home is almost 40 years old. Certain rooms were cold in the winter and our fireplace could no longer keep our family room warm and comfortable. In the summer months, the sunny side of our house was so hot, even with the AC on a lot.

Eric came out to complete a comprehensive home energy audit for us and provided us with detailed, thoughtful, and sensible recommendations for how we can make our home more energy efficient and comfortable. Notably, the proposal was clearly articulated and broken down into projects so that we could choose which recommendations, if any, to implement. We felt absolutely no pressure to do anything, but we ended up implementing all of his recommendations. The process was professional from start to finish, and we found the entire team to be highly knowledgeable, informative, and friendly. Comfenergy employs their crew - they do not hire contractors - with one exception. We scheduled an air duct sealing service and Comfenergy arranged this work with one of their partners.

The Comfenergy crew, led by Carlos, did an outstanding job! They showed up on time, worked constantly hard and communicated well! Carlos went above and beyond because there were a few pieces of insulation that were in bad shape (not part of our scheduled work) and he replaced them for us because he seemed to genuinely want us to have the best outcome. They cleaned up very nicely!

I wish we would have done this 5 years ago instead of suffering unnecessarily. Comfort, peace of mind, and knowing I have clean, sanitized, pest resistant insulation everywhere in my house and no leaks in my air ducts is priceless!

Mr Guzman and his team did a fantastic job removing the old insulation and upgrading the insulation in our attic. We couldn’t be happier and without reservation recommend them.

Great job by Comfenergy. Melvin was the team lead for all the work done. Him and his team were very professional, helpful, and nice. There was a lot of work done all over the house (mainly the attic) and they were able to keep everything clean and tidy. The best - well worth it!

We recently had Comfenergy insulate our attic and garage, and we couldn’t be happier with the results! Our house is noticeably warmer, and the difference in comfort is incredible. From start to finish, the process was seamless. Aaron, the salesman, was fantastic—so personable and easy to work with. He took the time to explain everything clearly and made sure we were comfortable with the plan. The team was professional, efficient, and delivered top-notch quality. We couldn’t have asked for a better company to handle this project. Highly recommend Comfenergy for anyone looking to improve their home’s insulation!

Used Comfenergy to add insulation and sound reducing insulation to a room above our garage. Very professional, from the front office to the job crew. Great communication; punctual; and services delivered as promised. Room is now comfortable temperature wise and noise has been significantly reduced. Crew left room clean. Will use this company again should need arise!

We had an all around great experience with Comfenergy from initial visit to job completion. They removed our insufficient attic insulation, then sealed the attic, foam coated the duct work, and sprayed in new insulation. The on-site team was friendly, kept the job site as clean as possible and then cleaned up after. I highly recommend.

We had a great experience with Comfenergy during a comprehensive project that included insulation removal, radiant barrier, full air sealing, and blown insulation in our attic space. The crew was on-time, knowledgeable, considerate, thoroughly professional, and courteous throughout the job. The job site was orderly and well-cleaned after all service was performed. I am very pleased with how well the project turned out!
