Wonderful experience! I just purchased my home and the new furnace had the Zenner and Ritter sticker on it…and since I’m unfamiliar with the area, I decided to go to them to add central air. The service was very prompt and courteous. The salesman came to my home on time and explained to me the various options and price points, as well as the importance of a “matched system” (same brand furnace and central air component) the installation went smooth and the guys were great. Explained the functionality and cleaned everything up. They even installed a new covered GFCI outlet to replace the existing one, even though it is not part of the cooling system. Next year I will be getting an air cleaner and humidifier. I highly recommend them!
