    "We hired them to replace our Air Ducts and add Air Blown Insulation. We re very happy with the outcome!. They re very reasonable. In summer the house never cooled off under 86 and the a/c never shut off. Our PG&E bills were $600-$800 during summer months and we paid on it all year. The Air Ducts required a lot more work than originally anticipated ( was originally built with several different sizes when it shouldn t have been plus an add on room. They showed us the old stuff they took out and there were holes throughout so most of the cold air was going into attic not house!) They paid special attention to the back part of the house that always is hotter than the rest of the house. Even putting extra thick insulation in that room. I spent the first 3days saying It s set to 74 and it s 74 in the house! It shut off! Highly recommend them if you need work done!"

    "I hired Americool to insulate the attic and walls of my exsisting home. Scott's bid for the job came in lower than what other companies wanted for just the attic. He and his crew showed up right on time and took only 6 hours to complete the job. They were pleasant,professional put down plastic to cover my floors for protection and thoroughly cleaned the jobsite when they were finished. Two days later and we already notice a big difference in the balance of temperatures and noise reduction. Great Job!"
