We were very happy with the work that Freschi Air Systems did for us. They installed a new heater and air-conditioner in our home at that time. They were very professional, prompt and efficient, and completed the job in the time they had allotted. At the same time, we had them install a new thermostat with technology that we were unfamiliar with, and they took the time to teach us how to use it. I would recommend them to a friend.
