    After receiving several quotes, Insulation Commandos stole the show. They have a slick…read morepresentation explaining the process...almost too slick, lol, but we couldn't be happier choosing this company to install Rock Wool Insulation in our newly purchased home. Considering the access they have to your house, it was important that everyone was trust-worthy, courteous, and passed the German Shepherd sniff test...all passed with flying colors. The crew did a great job sealing everything and making it look as pretty as it was effective. Their pricing was also extremely fair, literally coming in at half the price of at least one other competitor. I do not predict needing their service for many years, but when I do have an insulation issue, these guys will be the first call I make.

House was built in 1999, and definitely was stuggling in the summer like most do. Plus I have been in the HVAC industy 23 years so I understand R values and the importance of insulation for efficiency standards. Wally came out to look everything over and take measurements. He recommended that we top off the existing Rockwall insulation with 10" of new blown-in Rockwool Premium Plus, resulting in a new R value of R-40+ as there was nothing wrong with the existing so no need to remove it. Two man team came a couple weeks later, very professional and quickly blew in the new insulation, let me take a look in the attic to make sure it looked good, cleaned up and left. Even came back a week or so later to install an attic hatch for even better efficiency. Martha was who I dealt with the most via text and phone. She's very timely and will keep up with everything to make sure all goes smoothly. Just all around a great experience which seems to be lacking these days with many companies. Highly recommend using Insulation Commandos. Very fair pricing and amazing customer service!

There was no attempt to upsell and the promotional rate was offered. Paul Boyd, who is the owner is a certified and knowledgeable gentleman who is an expert in his field. He did an energy audit and identified areas to improve efficiencies. He also highlighted areas that were good, which is not something most businesses do. At no point was there a push to sell or upsell. His main focus was to ensure that the customer got the most from his visit. Will be using their services to fix some of the issues identified. The duct cleaning was scheduled for a different day. The techs arrived early and were very efficient and thorough in the job they performed. The work and cleanup was completed to my satisfaction. The pricing for the duct cleaning is competitive in comparison to other companies in the market. I highly recommend the services of Climate Doctors for your duct cleaning and sanitation. The superior ratings online are totally reflective of my personal experience with them.

I received a follow up from the actual owner of the company after hours, who was eager to share all of the finer details of the service. He then proceeded to offer to come out and do a free energy audit at my home. This is the company you wanna do business with. Great service excellent follow up and they had a better price than the other company I had been contacted by.

    Chances are if you live in an older home not built up to today's building codes, and even if you…read moredo, the insulation & ventilation in your attic may not be up to par with the current standards. My home was built in the late '70s, and the previous homeowners did nothing to rid the home of its original rockwhool insulation. The minuscule 6-8" of insulation that was once in my attic was ridden with rodent feces/urine, turning to dust, and wasn't as effective as it once was. This not only caused my home to have imbalanced heating/cooling, but also strained my HVAC system, making it work significantly harder than it otherwise would. Combine the lack of insulation with improper ventilation, and you set yourself up for a home that's not comfortable to live in, while in the process of taking precious dollars away from your pocket, all due to increased electric/gas bills. I called Energy Attic back in 2019 to see what they had to say about my attic, and they came out to do an energy audit. They filled me in on everything that was wrong, and what I could do to fix it. The estimate they provided was very insightful, breaking down the cost of every service, and allowing you as a homeowner to do what's best for your house and pocketbook. At the time I was unable to afford the job, so I decided to hold off on the project. Fast forward to early 2022, I gave them yet another call, and due to a mishap in getting the square footage of my home incorrect (was overestimated due to some vaulted ceilings), we decided to have them come back out to my house to give things a look. I spoke with their sales representative Mike for a decent amount of time, making sure I understood what was best. Mike's insight was incredibly valuable, and I ended up going with a whole host of things to improve my attic space: - Removing all old insulation - Sealing any air gaps - Spraying in fiberglass insulation to R49 (16") - Installing a radiant barrier - Upgrading existing fan with a solar fan Energy Attic ended up scheduling the job for the next week, and three of their employees ended up working for nine hours, knocking everything out of the park the same day. I've had a lot of contractors & such work on my home, and these gentlemen treated my home with dignity, cleaning up after themselves, and ensuring the job is done perfectly. Almost immediately I was able to notice the consistency in temperature throughout the home, and not just that, but also my HVAC system kicking on less. I'm stoked that the days of dealing with certain rooms being colder/hotter than others are gone, and my attic space can properly reflect any heat thrown at it away with the radiant barrier, and push any heat out that did get in with the solar fan, regardless of wind conditions outside. While a job like this is costly, making your home comfortable to live in year-round is very much worth it. I wouldn't hesitate to contact Energy Attic for any of your attic or HVAC needs. I'm pleased with what they have done, and I can't lie, my attic space sure does look better than ever!

    I should go edit my Google review. I'm very irritated and…read moreeven after days of giving myself to calm down, I'm still angry. I know for a fact that I asked if the quote and payment we gave for attic insulation, included over the garage. I was told yes, and I know I asked at least three times, and was told yes. The two other people in the home, heard it as well. The over the garage was not insulated. Now I understand, that I should have checked before I left the other review. That's on me. I shouldn't have taken anyone else's word, and I should have gotten the ladder and looked. When I texted the man who came here, I was told yes "no, it only includes over living space". The insulation over the living space is nicely done. I am very pleased with that. Just very irritated that, what I was told was going to happen, and included, turns out it's not.

They had a four hour…read moretime window for completing the project however they rushed and damaged my ceiling by walking too fast and aggressively on ceiling joists to swiftly complete the job, cracking my ceiling drywall in multiple locations. I would understand as I am a licensed structural engineer. Before they were about to leave I had to remind them that I also paid for installing batt insulation, if I hadn't, they would have left. My request to the estimator of making sure not to add insulation over my exhaust vents were not communicated to the workers so I asked and they were not aware of this ask. They were nice and fixed the very apparent crack, but weeks later a second one formed nearby due to the worker initiated the cracking by compromising the ceiling gypsum. I did not ask for them to fix this because how I can prove it? No one has walked up there since but enough time has passed to leave doubt on how it was caused. I would not recommend them.

After they had removed the old insulation Able, the crew chief, had me come look at what they had done. Next they sealed around all the light fixtures etc. Again, Able got me and I checked their work. Then they blew in the new insulation, which didn't take to long. I did a final check and they were on their way. During the process, Christal, I believe that was her name, call to see how things were going and again after the job was done. Also, they salesman, Ian, called to see how it all went. I might add that their price was considerably less that the other quote I received. This company is really worth using. I'm impressed! Keep up the good work, Green Attics. I hope you are around for a long time.

    Like some of the others, this is a bait and switch. The quote that they gave me was way too low…read more($129) and when the guy came in, Jerry, he quoted me $900. So, the background, I have an older furnace that had some black soot coming out of the vents and he said it was mold and mildew. He assessed the furnaces in the attic, and told me what he had to do. Sounded reasonable, so I agreed. This was on a Thursday. After he left, the problems were 1) the blower stopped working after he finished so I had no AC during that heat spell in May 2) there was a small gas odor after he finished 3) he didn't do the dryer vent cleaning because he had to be somewhere in the afternoon, at 2:30pm! He was telling me all the things wrong with my HVAC system as though he didn't want to do the work, but was completely interested in talking about the house that he was building and how great the HVAC was. But what's disappointing to me, especially, was his unprofessionalism. He didn't complete the job at 2:30pm because he had to "go to downtown to talk to the painters for his house that is being built." Like you are on company time, how many other jobs has he not finished or completed for his company to tend to personal matters? I paid in cash, so he likely didn't even report this job. I called another HVAC team and they fixed my furnace blower to just get the AC working but also gave me a great deal to just replace that old furnace upstairs. They were also the ones that explained all the bad work that was done prior, and the lack of work that Jerry did! When they ripped out the junction box, all the mold and stuff Jerry took a picture of was still there! The major thing was the gas leak, and fortunately my new HVAC guy found it. That could have been very dangerous. After the work of the other HVAC company was done and I had time to think about all that Jerry for NOA didn't do, he called me and said that he could come on the Saturday for the dryer vent cleaning. When I asked him what time, he said he'd check and get back to me. Then he never called me back. Then he calls me randomly on Sunday, the next day, and I cancelled on him at this point because I don't trust his work, or this company. Beware of NOA, and how they take advantage of you not knowing about HVAC. As a nurse, I naturally just wanted the best for my family in terms of air quality. But to damage the system I had in place, despite the age, and potentially cause more danger with a gas odor and leak, I don't think I can trust this company. Plus the fact that Jerry, was more concerned with his own personal project than helping me was a real turn off. He said it'd only take 10-15min, but didn't do it? Because of traffic to his paint match appointment? Bad value, bad customer service, bad work. Response time was good, but the only reason why I had to leave a star is because you can't leave a '0' star review.
