At the recommendation of several people, we had ADI Heating & Air Conditioning replace the entire HVAC system in our home in the summer of 2007. This is a two zone system and the work also required the relocation of some ductwork. We were well educated by Mr. Chazoom, the owner of ADI, on the various manufacturer’s and their systems and guided in a direction that has turned out to be an excellent choice for our needs. ADI was very competent and thorough throughout the work performed. They worked well with our general contractor; making themselves available when needed and also worked quickly in an effort to cause the least amount of inconvenience. We plan on using ADI for our annual service. It was a pleasure working with Mr. Chazoom and we would highly recommend his company.
