The newest version of the A. O. Smith app, available for iOS and Android devices, features three core functions that make this digital tool a must-have for contractors who install water heaters. Its water heater selection tool helps contractors guide a customer through their water heater purchase by asking short, simple questions about hot water usage. After weighing their answers and several local considerations, the app produces a variety of models for customers to choose from. The app also features a cross-reference lookup to match existing units to a replacement and a warranty check.
