"I recently had a Daikin gas furnace and A/C unit installed in my home. The salesman Chris was very helpful throughout the whole process. He was very easy going and knew his products. The two technicians Matthew and Jerson were very good. I was impressed by the quality of their work. They worked hard all day for two days installing both units. I would ask for them if I ever needed service. I would recommend this company to family and friends if they ever need units."
