Abstract

Apparatus for heating or cooling the levels of a multi-story building. A single furnace-air conditioning unit is utilized to heat or cool the levels as dictated by the settings of thermostats in each level. An arrangement is employed to direct heated air from the upper level to the lower level during the heating cycle to lessen temperature differentials between the upper and lower levels.
