Robert's was not the lowest though it was clear to me that he had the experience, expertise and straightforward communication style that I wanted to work with. I also liked that I could work directly with a (small) business owner vs a sales employee at a large company. Robert is easy to trust, very responsive, and helpful at every turn. I am very pleased with how everything runs and it's been a smaller impact on my energy bill than expected. Future maintenance is (unfortunately for us) out of scope for his current services but he also provided a recommended tech to work with, so I'm glad to have the referral. Highly recommend working with Robert.

Robert was incredibly professional, providing thorough suggestions and even teaching us a few things about our home's efficiency that we didn't know. He was extremely patient while walking me through the quotes and helped demystify the confusing catalog numbers for the various heat pumps. Beyond just the install, the team made genuine improvements to our setup, including a better duct arrangement and adding an extra vent. As parents of a toddler, we were worried about the mess, but the crew left the workspace clean and organized every single day. The project hardly disrupted our daily life. One year later, the system runs perfectly--the house cools down significantly faster than it used to. We will definitely be using them again!

The quoting process with Kevin was smooth and competitive, and the installation went well. We got another quote from another company that came in a little lower, but we were much more comfortable with the professionalism Kevin showed. Well, Kevin ended up matching the quote, making it an easy decision. After scheduling the initial install, I had to reschedule due to some things that came up on our end. When I called, the person I spoke with (I think it was Kim) was understanding and made it easy to adjust the dates without any hassles at all. The whole installation crew, including Eric, Osvaldo, and Andrew (and anyone else I may have missed!), were knowledgeable, efficient, and professional. They checked in to make sure we were happy with the placement of equipment and were proactive in giving us a heads up about any loud noise or strange odors. We are very happy with the end result and highly recommend the entire team!

In August 2025, we contracted with Super Green to clean and replace the insulation in our attic…read more Everything went well at the beginning. The workers were on time and they were very quick to start and finish. They cleaned up after themselves and were done within 5 hours. Bad part was they missed cleaning an area of the attic, didn't clean off the top of the heating system unit that they said they would do and there were areas that could of used more insulation. I tried to call the site inspector Avi , no response. I called the main office and was told he was on vacation and to call him the next week. After two weeks, I finally received a call back from Avi. Avi asked me to climb up into the attic and take pictures to send to him. I told him that I was not going to climb in the attic and that I was surprised he did not come after the work was complete to ensure it was properly cleaned. He said he would call me back and set up a time for him to inspect. It's now October 2025 and still no site or response from Avi. My advice is that before the workers leave, if you are able to climb and check the attic, do it, because you will never see them again!

We've worked with Rudy across both residential and commercial properties, and he has consistently…read moredelivered top-tier work every single time. His professionalism, responsiveness, and attention to detail truly stand out. What impressed me most is the quality of his installations and repairs -- inspectors have repeatedly recognized his work as exceptionally clean and done to a very high standard. That says a lot. He is timely, honest, knowledgeable, and takes real pride in his craft. Whether it's a service call, a complex install, or a larger commercial job, he handles everything efficiently and professionally from start to finish. It's rare to find trades professionals who combine quality workmanship with strong communication and integrity, but ACMAN absolutely does. Highly recommend to anyone looking for HVAC work done right.

The job involved removing old ductwork using a crane and replacing it with a Fujitsu mini split system featuring four indoor units. Rudy also updated the ducting for the existing swamp cooler and worked closely with our roofer to ensure everything was sealed correctly during an active reroof. He and his crew returned multiple times throughout the process, staying hands-on and involved at every stage to make sure the work was done right. Since then, I've brought Rudy onto a residential project in San Marcos, where he's replacing an outdated AC and furnace with a new Bryant system at a very competitive price. We also plan to have him install a new system on another upcoming project in Vista. Rudy is honest, hardworking, and has a dependable, professional crew. He takes the time to explain the work, is always punctual, and consistently goes above and beyond. I'm not an easy client to win over, but Rudy has absolutely earned my trust. He's now my go-to for anything HVAC. Highly recommend!

We have a home that has a basement. It has three opening with about 3100 sq ft of storage. During…read morethe 23 years we have lived here it became an area filled with everything that we brought from our prior house and a dumping ground for anything else. It also became to home to rats, rodents, urine, feces and chewed up belongings. It became obvious that this was a real hazard. Trying to find a company that could perform all the services that would be needed was difficult until I contacted Advanced Insulation System. There are not enough superlatives to describe this company. Everyone I have had contact with is professional, personable and hard working. First they had to empty the contents of the basement, which was an enormous job. I will show photos. Once emptied, the hazardous things, rats, rodents, feces, urine, chewed up belongings were removed. All the areas were sanitized and sealed against any intrusion by creatures. Heavy insulation plastics were used on the foundation and floors and insulation was blown in to seal the entire basement. They assigned workers to assist me in sorting out the contents of the basement. The things that I wanted to keep were sorted and placed in the basement, charity items were separated and they loaded up anything that was not salvageable in their big truck and took it to the dump. It seemed overwhelming until the fellows, who are very organized, helped me make decisions about what to keep, give to charity and throw away. This took many days and the crew were spectacular. They left everything clean and organized. I really appreciate the dedication and expertise they showed in dealing with this unhealthy and messy condition. The employees all represent the company in a positive light and I wouldn't hesitate to recommend them. I feel that their pricing was fair and everything was done to perfection.

Install went very smoothly and they installed a thermostat of my choosing, even though they mostly support nest. They even fixed an issue with my downstairs vents where they weren't getting airflow (One of the splitters came undone in a wall). Post install is where this company shined: Both the AC and Furnace went awry shortly after install. Marco came out promptly and spent a good chunk of his time investigating the AC to see what went wrong and got it working again. I did end up finding out post install that the AC cut-off box switch was failing and needed replacement. The heater had a manufacturing error where they had to reduce a part twice. Overall.
