Air & Heat Hospital have installed the central heat and air units in two of my properties. Their technicians are excellent. They are thorough and able to explain all of their work. I have never had any issues with their workmanship. One of the units had major complications, but it was the fault of the manufacturer. Air & Heat reached out to the manufacturer and replaced the unit with a new one. Now both units are working without issue. I will continue to use them, and recommend their service to others. I did some comparative shopping and their prices are excellent.
