The new variable-speed, two-stage Tempstar SmartComfort™ 80V gas furnace offers comfort and quiet operation in a low-profile, 80%-AFUE model, says the company. The use of high-efficiency, variable-speed dc blower motors reduces electrical consumption up to 80%, the company says. With the same controls as the company’s other two-stage furnaces, a dc motor failure will not automatically mean a lengthy no-heat or no-cool situation, says the manufacturer. Replacing the dc motor with a properly sized PSC motor will put the unit back in service.
