Unbelievably wonderful company. Cut our heating and cooling by more than 50%. Very courteous efficient workers, and no pressure sale. Free inspection and estimate. Go for it!

We used attic wise to get new insulation. We originally didn't think that is what we needed, so they had to explain to us how it would work and benefit. We gave ot a try and ot has literally paid off our energy bill went way down and the house temperature is way more pleasing. It's cool when it's hot and warm with its cold.

Installed attic & garage insulation that has saved us a lot of money here is Yuma AZ. They were very receptive and reacted quickly to some minor issues with install, so we were really impressed with warranty fixes. Highly recommend.

Prior to install the temperature in the house would easily rise to 87° by 2pm and the air conditioning would never keep up. After the install the temperature would sometimes get to 78° - 82° by late afternoon. Our a/c is in the attic and the although the ductwork is insulated. We opted not to wrap the ductwork. We are now looking to have Attic wise come back and do what I should have done the first time.

Peter O’Neill was scheduled to come out on 10/30/2025 @5:00pm to do an inspection on our home and didn’t show up or call. I called and he wanted to give us a quote over the phone, I said how can you give us a quote when you haven’t even inspected the home. I would not recommend this company and we are very disappointed.

Several years ago, I reached out to this company because the upstairs of my home is frequently uncomfortably hot and my power bills are very high. They recommended and installed radiant shielding and an attic fan. They said that this should make my home more comfortable and lower my energy bills. I want to be clear: As best I know, the products were installed exactly as promised and my attic looks similar to the attic photos provided by satisfied customers. I have described the service provided to others and been told that I was charged a reasonable price for all of this. However, I'm not getting the results that I was told to expect. I just got hit with a nearly $300 electric bill. My "energy use report" from Xcel says that I'm using about double what similar homes in my area are using. I received the exact service I was promised, but the performance is not what I was told to expect - that is the reason I am an unhappy customer. I am editing my review for clarity in response to the owner's response to my original review. Also, like many other people, I do not always use my legal name on the internet.

Professional service from folks at home show to salesman to installers. All promises have been met. This winter season will be the true test. Price was fair, service was on time and scheduled at a time that worked for us.

I met Tim at a county fair and he was very knowledgeable on this product. I have to admit, I was a bit weary at first however I decided to go ahead with the install of this product. The install employees were awesome!! They explained everything before they started, kept me informed and had pictures for me at the end of the install I just started turning on my fireplace for a few hours in the evening (to warm up the house). From 9 p.m. to 5 a.m. there wasn't any additional heat in my home and the thermostat only lost 2 degrees from the previous night. Tim was great as well as the installation crew!! Well worth the investment!

So happy we went with this company for added attic insulation. We were looking for a way to reduce the warm temperatures in our second story home, and the attic seemed like a great place to start. Pete lived up to his promises, as the worker showed up on time, worked diligently to install in a 100+ degrees attic space, and cleaned up any mess before he left. We were really happy with the work completed and in one month alone, our electricity bill usage has gone down by almost half compared to the previous years usage. Only regret is we wish we would have done it sooner.

Pete is AMAZING! My husband and I just bought our home last December and quickly noticed the shift in temperature from ground level to upstairs. We came across the Attic Wise booth at the fall home show in Denver and we’re so glad we met them. Excited to go through this process and will update once installed!

Our house is 45 years old and the attic insulation has deteriorated over the years. We knew it was time to add some new to bring it up to the current code. We came across AtticWise at the Denver Home and Garden Show and spent some time talking with them and learning about their product. We decided to have them come out and take a look at what we have. Mitch, the sales rep was very courteous, stepping through the process if we decided to buy. No high pressure at all. We decided to purchase more blow-in insulation and the Radiant Barrier. The installers came 2 days after we signed the contract and got right to it. They were also very courteous and cleaned up after themselves. It was just installed today so don't have any stats on how it is performing yet, but based on what I have seen, I think it is going to make a big difference in our heating and cooling bill. Stay tuned. ----------------------------------------------------------------------------------------------------- Adding to this review 6 months after the installation. Our home did not originally come with AC so when it was eventually installed the 2nd floor did not cool as well as the ground floor. It was pretty miserable to be up there in the heat of the summer days even though the ground floor was nice and cool. When walking up the stairs you could feel the transition about half way up. Now after adding additional insulation and the attic blanket it is a whole different story. Though not as cool as the ground floor it is still comfortable to be up there during the heat of the day. When the smoke is in the air at night and the attic fan cannot be used it, is cool enough to sleep with just the AC on. No more sleeping in sweat puddles. WHAT A BIG DIFFERENCE THIS HAS MADE. ONE OF THE BEST HOME IMPROVEMENTS WE HAVE MADE. I HIGHLY RECOMMEND IT!

We had the best experience and noticed the difference in temperature in our house IMMEDIATELY! Justin on the initial visit was very thorough and went over all of the options for our attic. Once we decided to move forward, the crew who arrived was very professional and Junior (The Crew Chief) went over all the details as they did them. We had a consult on a Tuesday and the job was finished by Thursday! Amazing service and product!!

They had an event at rib chop house, food was tasty, service not the best, after listening to the presentation we decided to have them come examine our attic. We moved into this house in 2020 and didn’t use the A/C because it wouldn’t cool the upstairs! The AC would run all day and the upstairs was like an oven anyway! Mitch came over and showed us pictures of the lack of insulation in the attic, even bare spots! We ordered the service, (the dinner was on Tuesday, and by Sunday night the work was done. Monday afternoon it was hot upstairs so I turned on the AC and cooled it down to 76 degrees, on Tuesday afternoon (on an 86 degree day) the upstairs had only risen to 77, and I didn’t need AC.

I hired Attic-Wise after visiting their booth at a home show in Denver. I have a tri-level home and was having extreme cold issues in the winter and suffocating heat in the summer in one of the bedrooms, specifically where my attic access is located. They installed the specialty blanket in my attic in February, and also reattached insulation that had fallen down, added new venting and baffles and added some plywood at my request to create additional storage. After the blanket was placed, I noticed immediately the first time the temperature dropped below 20°. I even kept that bedroom door closed just to test whether or not the blanket was working. That bedroom stayed noticeably warmer and consistent with the rest of the house, even with the door closed. The real test came when summer arrived, especially since that room has extreme sun exposure most of the day. Again, the temperature of that room is now consistent with the rest of the house… It does not heat up like the sauna that it used to be and the only thing that I have changed is adding the blanket in the attic directly above that room. And that is with keeping the door and window closed, with no airflow. I am stunned that the blanket made such a huge difference immediately. My experience with all of the representatives of Attic Wise was delightful. Pete is friendly, professional, highly knowledgeable and very reassuring, and just a great person in general. The 2 gentlemen that did the work were punctual, friendly, very respectful and answered all of my questions and did an excellent job cleaning up afterwards. I highly recommend Attic-Wise and their product! It has made my daughters room comfortable again, without needing a space heater or a portable AC cooler.

Mitch was fantastic in explaining the product and what it could do. The installation crew came the next day and expertly installed the product. They were so efficient and quiet; we hardly knew they were there. We were so impressed with the professionalism of everyone we worked with at Atticwise. 5 stars for sure!

Great crew, everyone is super nice. Any concerns or issues were promptly fixed and now my attic is sealed with available access if need be. It's BRILLIANT! I love it, five stars and thank you for the speedy set up!

We are very happy with our e-blanket that was installed in the attic and the solar fan on the roof. The crew was excellent, very efficient and did great work. In less than a year, we have already noticed savings on both our heating and electric bIlls. We highly recommend AtticWise!

AtticWise did a great job improving my attic insulation, as well as in my garage. Can't wait to see how much better my air conditioning works this summer!

Great people and great company!! Very flexible with schedule issues. Already can tell the attic blanket has made a difference; furnace doesn’t come on as often as it used to. Highly recommend this company and their products.

Pete and Mitch were great! And I lowered my nest by 2 degrees and it feels the same! Would definitely recommend the insulation!

We own a tri-level home. It was very difficult to maintain an average constant temperature on all three floors. The upstairs was always very hot in the summer, and it was freezing on the lower level. Pete advised that we put insulation in the attic above the two upstairs bedrooms. This helped tremendously. The air conditioning/heating system now is not working so hard and the upstairs was cool in the summertime. We were also losing heat in the bedrooms upstairs in the winter. The insulation has solved that problem also. Highly recommend this company.

Couldn’t be more pleased with the service we received from Pete with AtticWise! We had our home including garage installed with Radiant Barrier in October. Now in the middle of November, our garage hasn’t gotten below 58 degrees when we work out in the early morning!! Temperature outside is about 32 degrees. Yeah.. we’re happy 👍😀

I was happy with my experience with AtticWise. The sales team worked with me to find product options that fit my needs and my budget. The installation crew was fantastic and got the work done quickly.

During my meeting with Pete we discussed our challenge to keep our home cooler in the summer and warmer in the winter. Pete conducted an on sight evaluation, provided product education optional solutions to resolve our primary challenge. Pete then provided us with investment estimate. Later that evening (9p) we had additional questions. We contacted Pete to seek answers. As we continued with our conversation, Pete asked Randy (an owner) to join the conversation. When we ended the conversation all our questions were answered. Because we felt there was of a sincere desire to provide great customer focused service, we decided to use AtticWise to resolve the heating/cooling challenges in our home. Finally, just as Pete and Randy described, the crew arrived on time to start their work. They kept us informed throughout the install process. We also had a visit from Randy during the installation. When the job was completed…we knew we made the right/smart decision to choose AtticWise.

My husband noticed that the air conditioner wasn’t cycling all night, and definitely comes on much less frequently. The installers were amazing! So professional and polite. One of them even changed our air conditioner filter. They went the extra mile, getting some popcorn spray to use in a couple of places. They even coated the back door window, which is west facing and gets a lot of heat. Great experience from sales through installation!

Oh people are extremely nice and sweet. But their product does not work. The only warm room in my house was my bathroom. Now it's just as cold as the rest of the house. There has not been a single change in my electrical bill except I pay more now for it. I do not advise you to do this unless you do not like having money in your wallet.

Insulation was laid in my attic and the swamp cooler casing that came thru the ceiling in the hall was removed. The hole that left was repaired. The workers were friendly and very professional and cleaned once done. The temperature in the house has stayed where I have it set. Has not varied all day or night without the airconditioner running. Fantastic results.

All the people I've come in contact with from AtticWise have been amazing: professional, polite, positive, and happy! I decided to buy the product yesterday; it is completely installed today!! I can already feel a good difference in the temperature of my home and I know it will just get better. They gave me a great price; fast financing; professional installation - all with a smile and no pressure. I'm excited to see the energy savings as the months go by, and I feel good that these products are guaranteed for the life of the home!

We had the Radiant eShield installed in our attic of our multi level home and immediately noticed that there wasn't as much temperature variations between the 3 levels of our home. We are also very pleased with installing process and our installer Reyes. He did a very thorough job in both attics and wrapping the water heater.

Don Schuld

Tim and Reyes were great to work with. They accommodated our very short window of time. It appears that the work was exceptionally well done as well as the clean-up afterwards. We can highly recommend their services. The product has very good reviews although we'll need a bit more time before we can measure its full impact.

I previously lived in north Texas with a similar radiant barrier system installed. My energy bills were more than 50% less than neighbors without the same system. Today I had the system installed by AtticWise in the north Colorado Springs area. From first contact with Peter through installation was a quick process. While Peter was very interested in my business, he was not pushy and was very accommodating working on a price we could both agree with. The installation team was courteous, fairly expeditious, and cleaned up after their work. Hopefully I’ll soon see the same positive results I experienced in Texas.

Very friendly and helpful with any questions and suggestions for locations of solar roof fans and insulation.The team of installers were very friendly professional and cleaned up any mess while vacuuming at the end leaving no sign of work performed.

I've got to say Attic Wise has been an amazing company to work with from the dinner presentation to product install. We got a reflective blanket, fan, and ceramic ceiling paint. These folks are great! The presentation was clear and honest. The folks that came to our house were friendly and knowledgeable about the products. Worked with us for a fair price. The guys who came out to do the install were fast, efficient, and friendly. I would recommend Attic Wise company and product hands down. Anyday! Thanks guys!
