I had Michael and his crew replace my heating and air systems as well as removing and replacing the insulation and full duct sealing in the attic All of the equipment and insulation met or exceeded the standards to qualify for rebates from SMUD and PGE. They completed the job in two days and Michael was always accessible for questions or problems. I was very satisfied with the work that was done and believe that Airsmiths provided the best price for the job.
