They showed up early and did a quiet job and can’t wait for my A/C to get a break.
Great experience! Insulated the attic of my home at a great price! Lowered my electric bill. I recommend National Insulation of Waco!!
They came out, looked in the attic, gave me a fair price, and did a great job. They even let me inspect their work when they got done. No muss. No fuss. No doubt this will pay for itself within a year.

⭐⭐⭐⭐⭐ Irvin and his team at Aerodyne Insulation provided exceptional service for my parents' barndominium in Liberty Hill. Their professionalism stood out from the start—knowledgeable, thorough, and meticulous in prepping and cleaning the site. While their bid was the second cheapest, their work ethic and attention to detail were unmatched. I’m already planning to hire them again for my workshop walls before winter. Highly recommend!
these aerodyne guys are great, a friend recommended them... did my whole house including attic. clean work, on time, easy to deal with... and actually located in waco (not far away)
After using these guys my power bill went way down. It saved me so much money it pays for itself. Definitely recommend you insulate your house with these guys.

I had a great experience from start to finish. Estimator/Service Advisor Jeffrey Stuart accommodated my schedule by coming out when it was convenient for me. I had an afternoon open, so rather than pushing it out a week so it wouldn't be so hot while he was measuring(I wouldn't have blamed him, summer's really been hanging around this year), he came right over. I was impressed with his manner, professionalism, and expertise, so much so that I pulled the trigger and accepted the proposal shortly after he left. Next up was scheduler/coordinator Gie. She was pleasant, courteous, and responsive, and made me feel that she was going to be super accountable and diligent. She did what she said when she said without the typical misses or postponements/excuses so common these days. Project manager Tyler clearly laid the process out, and stopped by before and after. He made sure I was pleased and had no unanswered questions or concerns. I was lucky enough to get the install done by the team of Aldo and Armando. Prompt, competent, tidy and as quiet as circumstances/machinery allowed. They were just great and I was super comfortable to have them working at my home. Price was very reasonable too. AC is running less and garage is outside temp+ 3 or 4 degrees; it had been +20-25. Top notch job and I couldn't be more pleased!
Our experience with Superior Attic was fabulous. We had Jonathan out to check out the attic and provide us with different options for keeping the home very cool. We decided to go with the spray foam insulation between the rafters. We have just completed a full week with new insulation and so far have noticed a difference, cant wait to see our bill lower. We also had duct cleaning done which was needed. Seamless process!! Had another project done, came out great!! Love the process.
Superior Attic did a wonderful job from start to finish on our insulation replacement. I was impressed with the level of professionalism displayed by the entire team, including Steven, Tyler, Aldo, Jamie and office staff. Great communication and on time. The day of the job, the team worked hard all day, no loud music, no shouting or lounging around - just worked hard and finished the job ahead of schedule. They insulated areas that our builder had not, so this was well worth it! So happy with the work they did!

Carlos Lopez and his crew did a great job with our home and guest unit! I'd called several insulation companies but none of them offered to clean out the old rockwool and other old insulation, though our home had virtually none as prior owners had left it bare. Carlos was the only one who offered it and this was perfect! It took only 1 Saturday to clean out the main home and the guest unit. Then they came with foam and filled our main attic and guest unit attic with it in 1 day, so a total of 2 days to clean our main home and guest unit and then fill the attics with insulation foam. Now our home looks like a little winter wonderland on the inside as it keeps the house evenly warm (and cool in winter) and it has helped to muffle a lot of the noise from animals scurrying on the roof, debris hitting the shingles, and overall noise. My wife and I also noticed that we are sleeping better and deeper now without late night roof noises affecting us as well as the even insulation and temperature of the home. Also the price was very good for what we got. Would recommend him to anybody! Including the before and after photos.
I couldn’t be more impressed with the service I received from Lopez Pro Insulation. From the initial consultation to the final inspection, every step of the process was handled with professionalism, expertise, and genuine care. They took the time to explain all our options, answered every question with patience, and provided a clear, detailed quote. On installation day, they arrived on time and worked efficiently. The quality of the insulation is outstanding — I noticed an immediate difference.
Carlos and his team did a great job on my attic insulation. Very knowledgeable and helped me decide which option was best for my needs. Quick professional communication and scheduling. High quality work at a good price. I highly recommend! In fact, I've already hired them for additional work.

Every single employee is extremely professional, I'm shocked at the difference between Thermo Dynamic and other companies. Very prompt and friendly staff, very detailed prep work, amazing foam job. Price was right in line with competition but considering the quality and finished thickness, it was an outstanding price.
Simple, easy and fast unloading Justin the unloader was super nice. Will come here again. 💯
Picked a load from here to Houston area, very nice place, fast loading less than hour.
