We hired Eco Friendly Insulation and were so impressed with their entire process. From the start, they educated us on sustainable material options like recycled denim and cellulose, helping us choose the best one for our home and the planet. The crew was professional, incredibly tidy, and took great care to minimize waste. Not only is our home now perfectly comfortable and energy-efficient, but we also have peace of mind knowing our choice was environmentally responsible. A fantastic company that truly walks the talk.

What struck me wasn’t just the result, but the intelligence behind it. Every detail seemed intentional, never ornamental.
Choosing Climate Guard was one of the best investments we've made. They handled a whole-home insulation upgrade with seamless professionalism. The project manager kept us informed at every stage, and the field crew was expert-level in their skill and coordination. They didn't just install insulation; they built a comprehensive climate guard around our living space. The improvement in daily comfort and energy efficiency is significant and immediate. Highly recommended for serious, long-term results.
We hired Climate Guard Insulation after enduring another sweltering summer with an AC that couldn't keep up. Their team provided a comprehensive assessment and designed a system specifically to guard our home against extreme outdoor temperatures. They installed a radiant barrier and upgraded our attic insulation significantly. The crew was professional, efficient, and spotlessly clean. The difference is profound; our home now maintains a comfortable, stable climate inside no matter the weather outside. They truly are climate guardians.

Their work shows not just experience but taste. It’s elegant without being excessive.
We had a great experience. After getting a couple of estimates that seemed high, Save Smart Insulation offered a sensible plan that fit our budget perfectly. The team arrived on time, worked efficiently as a group, and left the attic area spotless. The improvement in our home's ability to stay cool in the afternoon sun is remarkable. They helped us save money on the installation and will help us save on energy for years to come. Highly recommended.

I had Ram Insulation help with my attached garage project. They showed up on time with three-man crew and completed my 20' by 20' garage insulation within a day. They have done very nice and detail-oriented work and my garage looks brand new and ready for the next step.
Miguel and his team were referred to us by our HVAC vendor. We had them remove and replace the insulation in our home. Miguel, Adolfo and the crew were punctual and professional throughout the project. The entire project took 3 days and they did a great job of prepping our home, covering areas to protect and keep clean, removing the old insulation, and cleaning out any remaining debris before installing the new material. Adolfo took the time to explain what would happen during each part of the process including what things I can expect from having the work done. They were also good about the cleanup work when they finished. I already notice the difference in how much the new insulation is helping block out the heat inside my home. Hard working and dedicated crew. Would highly recommend using RAM for your home insulation needs.
Miguel’s team, Hector and Alfonso did an outstanding job of insulating our attic. They came bright and early and blew in insulation as well as laid rolls of insulation throughout our space. They were professional and courteous. They even had to deal with sharing space with a painting crew that was at our house to finish up a project. Super good folks and the insulation project was priced very competitively. Give Miguel a chance to bid for your business. You won’t regret it.

The crew was respectful of our property and their clean-up was impeccable. Our home is more comfortable, and we have peace of mind knowing the space is clean and well-ventilated.
We had a wonderful experience. The consultant from Fresh Breeze was honest and pointed out that our existing insulation was restricting vital airflow. Their removal and replacement service was seamless. The crew worked diligently, contained all the dust, and left the attic looking brand new. The improvement in our home's thermal efficiency is matched by the noticeable freshness in the air. It's clear they specialize in creating a healthy, high-performance attic environment.

Outstanding job on a timely repair and upgrade. We had a small roof leak that damaged some insulation. Lake Forest Attic Insulation responded quickly, removed the wet material, checked for mold, and then reinsulated the entire area to match the existing coverage. They went above and beyond to ensure our attic was healthy and efficient. The crew was professional, the price was fair, and the work was perfect. A reliable company you can count on for both projects and repairs.
I was particularly impressed by the integrity of this company. During the estimate, they pointed out that our main issue was actually a lack of ventilation, not just insulation. They provided a solution that addressed both, ensuring we wouldn't have moisture problems down the line. The installation crew was equally honest and hardworking. They transformed our attic into a properly functioning space. Since the upgrade, our HVAC system runs less and our home is consistently comfortable. Lake Forest Attic Insulation is the definition of professional and trustworthy.
Very knowledgeable and patient with all our questions. We are first-time homeowners and wanted to understand the process. The team from Lake Forest Attic Insulation took the time to educate us on the importance of R-value, air sealing, and ventilation. Their installation matched their explanation—meticulous and thorough. We now have a much more efficient and comfortable home, and we understand why. A fantastic educational and service experience.

We’ve always had amazing experiences with Total Comfort, and yesterday was no exception! Their technician, Ricardo, came out and quickly resolved our heater issue. He was incredibly professional, super attentive, and just an all-around great guy. You can tell he genuinely cares about his work and making sure everything is perfect. Highly recommend Total Comfort—Amazing Customer Service!
Total Comfort came to my house (via my new home build warranty). After explaining issue to the tech Ricardo, he quickly got up in the attic, diagnosed, fixed the problem and explained what he had to do. It seemed like only a few minutes and he was gone. I wouldn’t hesitate using Total Comfort again, even after warranty expires with builder . Thanks again to total comfort and my tech Ricardo.
Ricardo showed up to perform a warranty repair on the heater on my new home. He was able to identify and repair the issue on the spot, and corrected a wiring issue left by the contractor who performed the original install. He was efficient, professional, and skilled at his job.
