23, less than half as large. Low air flow was probably a major cause of the problem. Too-Low Delivered Air Temperature with Heat Pumps In heat pump systems the delivered air temperature is usually quite a bit lower than it is with most furnaces. This is because the efficiency of a heat pump is maximized if the condensing temperature is kept low, whereas the efficiency of a furnace is not affected very much by the temperature of the delivered air. Heat pumps generally deliver air to the supply plenum at 85 to 110 “F.

Note once again that, for many customers, the dollar savings will be merely thefiostifzg on tlte cake. Once they realize the thermal comfort, health and safety benefits of a good duct system, they may be willing to accept that there will be dollar savings and let it go at that.
