When I reached out in May for an attic insulation project estimate, Francisco was so responsive and…read moreset up a time to stop by and take care of the estimate within a day. Unlike some of the businesses we'd contacted, he did more than pop his head into our attic space and give us a cost. He carefully examined our attic space so that he could not only gauge how much insulation we needed but also how to best air seal the attic to increase the insulation efficiency. His final quote for the project was reasonable, and we arranged for a date and time for the project to occur. Not only was the crew on time, they completed the project as promised and were respectful of our living space, doing their best to minimize attic dust and grime from escaping into the main floor where we live. Thank you, Francisco, and your crew for completing the project on time, as promised. Your professionalism and commitment to seeing a project through successfully speaks volumes about your business. I wish you all the best and have already recommended you to other people I know who are in the market for home insulation.

Every other company we called just wanted to do a total replacement which was going to cost a fortune. Jesus assessed what areas needed replacement and what areas were still viable.

I reached out to Colorado Eco Insulation for a quote and they were super quick to respond and came to check out our house within a day.

We popped our heads in the attic and sure enough, the job was done beautifully and we are very much looking forward to cooler summers and warmer winters. They did a phenomenal job from start to finish and we highly recommend them!

That is not the norm when interacting with the trades. My HVAC system had a pipe break and it was leaking water over electrical cords. This was an electrical hazard in the making. The leaky pipe was spilling water all over the play yard of my dog training facility. My team could not use the space, as the water was growing an ecosystem and the dogs wanted to lap it up like a kale fruit drink. Hello giardia! Sean noticed that our HVAC system was not sealed, so we were essentially heating and cooling the outside. They sealed what needed sealing and replaced our air filters. My understanding is that the team primarily does insulation in Denver, so they can help with that, too. Drug-free crew...no meth mouth. Hire these people.

I couldn't be happier with my choice to hire Mark and make this energy investment in our home. I…read morewish we would have contacted Mark before spending thousands on HVAC upgrades, thinking that would make our home more comfortable. As it turned out, we had lacking insulation in our attic and no insulation at all in our exterior walls. Mark presented us with several options and guided us toward the option that would have the most immediate impact and fit our budget. He filed all of the paperwork for the Xcel rebate. While Xcel took quite a while to process the rebate, it ended up being substantially more than I was expecting and certainly help offset the costs improving the insulation throughout our home. Before the improvements, the second level of our 2-story home was significantly hotter in the Summer or colder in the Winter, than the main floor. Now, we have consistent temps throughout the house and are seeing lower Xcel bills too. Mark and his assistant were courteous and professional throughout the 2-day job and very Covid conscious as well, which was appreciated. Highly recommended!!!

If you're looking for a company that grossly overpromises, barely delivers, strings you along, and…read morethen ghosts you completely, then look no further than Ideal Home Energy. They sold us $35,000 solar panels in October of 2022, installed them in December, and then basically ignored us until April without getting the panels inspected/approved by the county. That's when I was FINALLY able to get in touch with Forrest, the owner, to try to get this project moved along. Forrest is the one who has continued the practice at IHE of overpromising and delivering next to nothing, as he told me over and over again that he was personally handling our job and that we were THIS close to getting it over the finish line. That was in April of 2023. Fast forward to now (mid-November)... four failed inspections later (many of which were due to his electrician not showing up at all), and now Forrest won't return my calls or texts. We have a lawyer who has sent a demand letter five days ago - still no response from Forrest nor anybody at IHE. I'm guessing we will have to sue him for all of our losses and future losses. I'm also aware that we are one of MANY clients who have been burned by him, so I'd expect more of this to hit him. I'd be careful buying their other services as well, since this could all blow up in his face. Additionally, Forrest promised to pay the electrical portion of our Xcel Energy bills, since we've been paying the financing on this system since February (for panels that are NOT functional) and therefore paying double what our energy bills used to be. He reimbursed us for March, April and May, but then stopped.... I guess we just have to eat the June, July, August, September, October, November, etc. etc. etc. costs that HE put us in. Beware of the glowing reviews of Ideal Home Energy and Forrest - he's just a good salesperson that tells you what you want to hear. Don't get burned like we did.

I hired this company to do air sealing and new insulation in my older Denver house. They were kind…read moreof a case of over-promising and under-delivering. But, to be fair, they didn't charge me for the things they didn't deliver. On the day that the work was done, the techs ended up not doing any air sealing. It wasn't entirely clear to me why, either the house didn't need it or it couldn't be done. Of course they didn't charge me for it, but that also meant I didn't get the Xcel rebate, which requires air sealing to be done. This seemed like something they should've figured out when they came out to do a quote. I also have a room without attic space above it, but I knew for a fact that the rafter space between ceiling and roof can be accessed from the main attic. So I asked them to include that in the quote and blow some insulation into that space. At the end of the work, the tech said they couldn't because there was no access to that space. By that point it was too late to try to convince them otherwise, since they'd already packed up. They adjusted the invoice to not charge me for that space, but I'm still left with a room without any insulation above it. They also installed a solar attic vent fan. Initially when they arrived, they said they'd have to reschedule that work, since they didn't have a fan in stock, but ended up locating one and installing it. I understand that there are supply chain woes, but when I had to make the appointment 2 months in advance, it kinda felt like they could've worked those issues out. There were also a few other things they said they'd do but ended up not doing without much explanation, including sealing/insulating the attic hatch, and installing vent baffles. I hate to be ageist, but both the person who came out to do the quote and the two techs looked to be in their 20s, so I couldn't help but wonder if they simply weren't experienced enough to know how to do all these things in an older home, and were primarily trained to go into an attic with a hose and spray insulation til done. In the end, the work they did do was fine. No damage or mess, and plenty of new insulation in the attic. But I don't know that it was really worth it. They said I should see a reduction in energy bills of something like 10%, but that's hard to measure when a) my bills are already pretty low and b) bills will change by 10% or more month-to-month based on just the weather. I had hoped that at least the new insulation would help reduce the large temperature differential between the levels in my house, but thus far that seems to not be the case, and I can't say I've noticed the a/c running less than it used to. So I don't regret having the work done, since the previous insulation was desperately out of date, and hopefully I'll see bigger dividends in the winter. But thus far it hasn't really made much difference.
