How warm should heat pump air be?
Heat pumps usually produce air that is 85-92°F. This is plenty warm to heat your home to your desired 72°F. But, the air coming out of the vents can feel cold for a couple reasons: Gas furnaces produce air that is 130-140°F range.
What to do about cold air coming from heat vents?
You MIGHT be able to turn the furnace on to a warmer temp, let it run for some period of time (10 minutes?), then take an infrared thermometer and shoot the chase to see if/where there are warm spots… And/or do a visual inspection to find openings…
