Brrrr...is my heat pump doing what it should?

It's 22 deg. right now and my home is at 65 deg. (night setting) My heat pump is putting out 83 deg. air. Is this what I should expect? Although I've had a heat pump for 7 years I've never really paid attention to what heat it produces....that is until I got a new laser thermometer as a gift this Christmas. I know know the surface temperature of just about everything I own.............:laughing: I know the cooling differential can be anywhere from 14 to 20 degrees (return to supply air) and I'm guessing that during the heating season this would be the same. Am I on track with this? By the way, the house stays comfortable, but during this last summer when it stayed over 100, and a few times 110 deg. it had a difficult time keeping it at 73 deg.
Any other heat pump owners with some advice or comments?
