"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"Summary: The Comfy team did a great job b/c they know what they are doing however, they are not without faults. Work Completed: Full crawlspace escalation and turning a vented attic into an unvented attic by adding CC spray from on the roof deck. Time frame: July 13-17 2020 Results: We are only a month out from the work being completed, so the analysis is on-going but here are the numbers so far. My Aug electricity bill was down 26% in real dollars from July. That reduction is in spite of the fact that Aug had a 31% higher average Cooling Degree Days (base Temp 70F - [*** Link removed ***] In addition, the first week of my Aug billing cycle included this work. Again, this is very early on but that is a promising start. Other benefits include less variability in house temperature. Before I would see a temperature difference of 5 degrees Fahrenheit between my bottom and top floors. Now they are no more than 1.5 degrees apart (the thermostat is on the lowest level). This creates an overall more pleasant living environment. So while I’m looking at a return on investment that stretches out past 10 years, during that time it’ll be a more comfortable home to live in. Challenges: My only complaint is that there doesn’t seem to be a solid quality control program. To be fair, I have high standards of work quality. Especially when I’m paying for it. Comfy clearly understands the science and best practices. It’s always a challenge translating that over to the real world, which is messy. With that said I felt like I was the one that had to be pointing out the areas of poor workmanship. It sure would have been nice to feel like that quality control was being done for me. Now for the good news, Comfy is correcting all the issues I have pointed out (scheduled but not all completed). Bottom Line: Comfy has a talented team of people, who know the work. They will do a good job at a fair price. But don’t let the sleek marketing and science lull you into a false sense of security, make sure you get what you paid for."

"The work here in 2023 was a re-do of work done in 2016, of the top floor of this house, with a Mansard roof. It was basically uninsulated in 2016, and the work then had a big impact because at least some insulation was blown in. But large regions which I was told had been filled were not. I borrowed an IR camera, which showed that one wall that had been filled in was losing its fluff. The work this time here in 2023 was to fill in the parts of the wall not filled in last time, and restore any insulation lost during the pandemic years. They also added additional insulation to parts of a wall not covered the first time. It's had a very noticeable effect. The temperature before the re-do was sometimes sweltering—I couldn't keep chocolate up here, lest it melt—but after filling in the walls fully, even on those days that tell us climate change is looming, the upstairs is comfortably habitable. The total I gave of $3,800 includes the full project, including $1,500 for this round."

"After researching and obtaining quotes from a number of companies, I selected The Fifth Fuel to air seal and insulate my attic (blown-in cellulose), cantilevers, and rim-joist. From the initial consultation with Adam to email follow-up, the project and my options were clearly explained. When I asked about putting a higher R-value in my attic, Adam provided the price but explained why it didn't make sense for me. I appreciated that he didn't try to oversell me. The proposal laid out everything they would be doing. The cost was reasonable. It wasn't the lowest bid, but was less than 50% of some other bids. The day of installation, the crew arrived a bit early. Throughout the install they were professional, kind, and clean. They protected the inside and outside of our house and vacuumed afterward. They conducted a blower door test at the end to quantify the difference made by air sealing. Within two hours of them leaving, we've already noticed a difference in our comfort and our A/C is not even running half the time it was before."

"I am so impressed with Comfenergy. The sales rep explained why we only needed to improve the insulation at the top of our unfinished basement walls, not the whole thing as another company recommended. So it was considerably less money than we thought we’d need to do the job. Brent and his assistant arrived on time to do the work and were so quiet that we weren’t inconvenienced in any way. I definitely recommend this company."
