“They exceeded my expectations with timing. They did an upstairs hallway for me, because they had the paint out and they had the time. They did a lot of repainting when they had some paint that didn't take the first time. Even after they were done, they took out fixtures and redid it again just because it was not perfect. They went above and beyond. They did little things for me added on which was convenient and no charge. Everything was perfect.”

“A gentleman who did the follow up work went beyond the basics - there was an item (attic hatch) that did not make it on the project list, but was leaking air. He came up with a solution to address the issue and did the extra work.”

“Shayne Sandner was great. Cyrus and James (Sorry I don?t have there last names. Did a great job fixing some quality issues. If they would have been on the job from the start I don?t think there would have been issues. In addition all my communication with Justin Dobson was positive, helpful and reasonable.”

“it does seem that the insulation is making a difference in keeping temperatures more stable in the house”

“I had an absolutely terrible experience with this company. We ordered windows from the company in September 2020. Signed the contract and everything towards the beginning of the month. We were told that it could take 6-8 weeks for the windows to be ordered and arrive to be installed. We though, okay fine since timeframe for installation should be in October. Two weeks later the guy came to take the measurements, which pushed back our installation but still thought as long as they are in the by the winter, it will save us money on heating bills. The person they sent to take the measurements was unfortunately pretty rude and seems more bothered by the fact that two of the windows would require custom measurements due to the unusual size and shape. Again, thought whatever as long as we get our windows in before temps get cold. Then October rolls around I send an email checking the status of the order. At that point, I'm told that they need to revise the order since supposedly the factory said they couldn't make two of the windows, keep in mind this was well over a month since the measurements were taken. So at that point, our order I think was actually put in. Again, I thought okay end of November maybe beginning of December is when they should be ready. Those months roll around and with me being the one to constantly reach out to check the status. I have all of this in email traffic too to verify dates. Long story short, we did not receive our windows and have them installed until beginning of JANUARY!!!! 4 months after we signed the contract and paid our deposit. And all I received was maybe an "i'm sorry email". I will never use this company again and based on how we were treated as customers. I always had to be the one reaching out and sometimes I would get a response and sometimes I wouldn't. So I'd have to stay on top of it and if I had not, we would have maybe received our windows sometime in the Spring. Absolutely terrible customer service all around!!!”

“Our second floor level used to get hot in the summer months, up to 80 degrees with the AC running. We thought it was a roof fan issue, but Comfenergy recommended sealing all airflows into the attic and reinsulating. Their work entirely solved the problem. Now in the summer months, our upstairs stays at the temperature that we set, and our summer electricity bills are about $100 less than before.”

“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.”
