D T Mccall & Sons

At Westinghouse, we take great pride in our heating and air products, and build each one to provide years of worry-free comfort. We do this through a manufacturing process called Demand Flow Technology (DFT). We are the first and only heating and cooling manufacturer certified in DFT. With DFT, we test each and every air conditioner and furnace we make. In fact, each product goes through our "check, check and recheck" process at every station during the process. Before our heating and air systems leave the factory, gas furnaces are checked about 234 times and air conditioners are checked about 144 times. The final analysis is at our quality control station where we perform 100% computer automated testing to eliminate human error. The confidence we place in our manufacturing process allows us to offer an extensive warranty and Quality Pledge. All Westinghouse heating and cooling products are proudly designed and assembled in the United States. Our plants are located in Missouri and Tennessee, the heart of the Midwest.
