Robert Carroll, the owner, has 30 years of experience in the insulation and ventilation business. Attic Air has been in business since 1996 and specializes in insulating and ventilating residential homes. Attic-Air will come out free of charge to evaluate your home. Robert Carroll will be at every site to ensure a job well done and that you will be a satisfied customer. (No subcontractors used)
"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."
