Our furnace and air conditioner were on their last legs after 15 years of operation so we decided to replace them proactively. We received quotes from Air Quality Dunrite and 3 other companies. Air Quality Dunrite has been servicing our old equipment for over 10 years. Marcello was the only person who actually asked questions, heard our problems, listened to our answers and inspected the equipment to find a solution. He suggested zoning our system with automatic dampers and although it was a bit more expensive, it appears to have solved the problem of heating and cooling the remote house areas. An excellent job with great installation and a very happy customer.
