    We had a wonderful experience with Jamison Heating & Cooling when they installed two heat pump…read moresystems for us, so when it was time for our one-year maintenance, they were the obvious choice. I called to schedule the service, and fortunately, due to a cancellation, Janette was able to get us in the very next day. Our appointment window was getting close to ending, and I completely understand that service calls can sometimes take longer than expected. Cesar called to let me know he was going to take his lunch break and wanted to check whether we were still available. I really appreciated that he took the time to keep us updated rather than simply showing up later. When Cesar arrived, he first asked how our heat pump systems were working and then explained what the maintenance service would include and whether we had any questions. He was extremely thorough and walked us through his findings along the way. When he finished, he again took the time to ask if we had any questions and made sure we understood everything. We really appreciated Cesar's professionalism, knowledge, and friendly customer service. It's clear that Ryan, the owner, has built a team that genuinely cares about its customers. If you're in Orange County and need service or maintenance for your heat pump system, I highly recommend Jamison Heating & Cooling. And if you have the opportunity to have Cesar come out, you'll be in great hands!

    Ryan I did get a hold of the company that installed it and they repaired it a couple days later…read more The real focus here is how your company handled the situation from the start. Your reply should speak directly to how you plan to improve future customer experiences, especially around communication, responsibility, and follow‑through. My recommendation is that you avoid deflecting the issue or shifting the conversation toward promoting your company's warranty or services. What matters most is acknowledging what went wrong and outlining how your team will prevent similar situations moving forward.

    This family business is fantastic! From the moment I called, they walked me through every step of…read morethe process, explained all of the different insulation materials, and gave pricing right over the phone! The four other companies I called had someone come out and give me ridiculous high pricing and barely explained what insulation is best for my attic and WHY!!! The crew, Juan and his assistant, came out and cleaned everything out! Jose and Richard came out the next day on time, installed blown in insulation in 2 hours. They were quick, super clean, and friendly. They even took pictures before and after. I'm happy I found this company. The price saved me around $2000 compared to the other quotes I got. I enjoyed talking with Cynthia and Emi in the office. I will call them again for my walls next year after a few more projects I got to take care of. Highly recommend!

    Terrible experience with this company. The original invoice they sent me was for $1,060. Cynthia…read morein their front office called me six weeks after the work was performed and told me I owed an additional $424 for a radiant barrier they never completed. When I said my invoice was paid in full previously and that I needed to see an invoice showing me what she was saying, she hung up and created a new invoice showing I owed an additional $630. I paid the invoice but when I sent the company all of the correspondence showing their mistake and asking for a refund for the overpayments they ignored me. There are hundreds of insulation companies in LA. Stay away from this one. I have all the images and voicemails saved if anyone wants to see them. Please don't use this company.

Old wood, minimal insulation, general chaos. Our HVAC contractor recommended pairing the new setup with fresh insulation and a radiant barrier to get the most out of our AC, so we got several quotes. 911 Attic Insulation came in mid-range on price, but they were the only company to include crawl space rodent proofing as part of the package, which pushed them to the top of the list. Daniel, the owner, was easy to reach and responsive throughout. When we talked numbers, he worked with us to fit our budget, which we really appreciated. The crew came out and handled everything in a single day. I'll be honest: our attic was a genuinely rough starting point. After the work was done, we noticed a recessed light had come loose. I reached out to Daniel and, without any hassle, he had someone out the very next day to fix it. On a weekend. That kind of follow-through says a lot. Overall, a great experience from start to finish. Competitive pricing, willingness to work with you, a thorough scope of work, and a company that stands behind what they do. Would recommend without reservation.

    I needed some attic and crawl space insulation and Beni K. (Project manager) came over the next day…read moreto assess my situation and give me a quote. He stayed for a couple hours because I had a lot of questions and he provided me with insightful information to help me make my decision. He provided me with a quote on the spot and worked with my budget. I went with Pure Eco because of Beni's experience and his transparency. The next day Armando (Foreman) came by in the morning with his team to begin working on the attic and crawl space. They were efficient and were very careful walking around the house while working. Beni came by in the afternoon to check on the project and to make sure everything was up to my standards which made me feel reassured that I was getting a good installation. I checked on the attic and crawl space while they were working and it looked great. After the job, Beni and his team sent me a link to all the before and after photos to ensure that the installation was done.

    I asked for a rough estimate online without an inspection for a typical 1100 square foot house…read more They told me it it was illegal for them to give a rough estimate without an in person inspection because they are licensed. A few of the places I checked with didn't want to give a rough estimate, but none of the them lied about their reasoning, so they didn't get reviews. Some even gave me a rough estimate right here on yelp. Based on some of the other reviews, it seems like this sort of pressured sales approach is their business model, instead of helpful answers and good work.
