Just had a heat pump added to our propane furnace as a dual fuel setup. Works as expected until the outside temp goes below the switchover point. Until the outside temp gets back above that switchover point, the blower/fan runs nonstop. Outside unit is not running. The propane furnace is running intermittenly, I guess as needed, but the blower doesn't ever cut off.
Is this normal or do we have a problem? Doesn't seem right to me, but I'm not the expert.
