Heat pumps do have the ability to tell you gas/oil furnace to "help out" - this is what I was really wondering. I am not sure there is anything wrong with my system, if the heat pump calls for aux heat because it cannot "keep up" then maybe mine is working as it should. I was under the impression that the thermostat controlled this and only called for Aux heat if the heat pump was not getting the house up to temp fast enough...
