What temp is it in your house.

What model 14 SEER is it, and what model is the indoor unit.

How long is the defrost timer set for. That varies how often it goes into defrost once the coils temp is below 28F.

Ok. Now if you posted the indoor coil info that would help.

But, if its 30 outside, and its 70 inside. maybe 90 to 94 depending on CFM through the coil.

Running on only heat pump no aux (elec, gas, etc.) and 30F outside temp out of register will be a blistering 95F if you are lucky!. The one we had in new jersey a few years ago would give 82-85F at those temps. remember it is taking what heat is outside ( heat is anything warmer than the refrigerant in your Heat Pump can transfer from outside to inside your house). In winter it takes a long time to accompligh this. A Heat Pump will naturally run a long time in witer. Only when it can't keep up will it finally bring in the aux heat to maintain the temp. Let it run, let it reach top efficiency and as long as you are "comfortable" you can save money. Don't play with the thermostat. Set it and forget it. Or be very deliberate when you do change the settings. NEVER ever go more than 2 higher at a time if you want to bring up the houses temperature. Otherwise you will turn on the electric coils or the gas( Exception to all this is if you have a hybrid system and have very cheap Natural Gas available, cheap propane around or electric is cheap. Probably not gunna happen so put on a sweater and don't sit close to the register and remeber you are saving money and the world by conserving.

That unit will do 90 to 94 at 30 outside, if the indoor is 70.

That is a good performing heat pump. The one you had in NJ probably wasn't a 14 SEER.

yeah, that one was a few years old as I mentioned so it probably was more like a 10 or so SEER ( changed out the first one in the late 1980's. so this replacement R-22 was built about that time) Heck our first one that we bought was back in 1976 used R-12 yes R-12 just like the old car air conditioners. Name brand state of the art for the time, a Carrier. Just goes to show how much the technology has advanced. So yes today a temp of 95 at the register from outside temperature at 30F and indoor temp of 70 to me is a "blistering" number if you consider what older units put out. I wasn't critizing just letting the poster know that he shouldn't expect it to perform like a conventional fossel fuel furnace that belches out 110F+ from the registers. Heap Pumps are a great way to heat and cool. just have to understand that they are a "little" different in their performance.
