I can tell you that my heat pump set up at my condo is absolute trash here in Northern Ohio. Running 24/7 it is unable to get my condo above 62 deg F. It blows cold-ish air under an outside temperature of 40 deg F. Windows are new, doors are weather stripped. I'm having it run it in supplemental mode just to get it above 65 deg F.

There are some very bad heat pumps out there. The difference in usability varies dramatically. Some heat pumps will produce heat even below 0F. Others are crappy at anything under 40F.

Something must be wrong. My heatpump will run you out of the house at 40F outside. Below 20F it puts out so so heat but can maintain. Below 10F electric heat is needed from time to time to maintain. Below 0F heat pump is worthless. Edit: Wanted to add my is air heatpump, not ground source. Also reading other comments looks like heatpumps range from amazing to utter crap.

1. Have an HVAC tech inspect it (~$100-150). 2. If it's not a coolant or compressor issue, you might need to replace it (either because it is undersized or end of life). Your local government or utility might have energy incentives for replacing it. There are also federal tax credit incentives [1].

Your heat pump just does not have sufficient capacity. It's not problem of heat pump per se.

Your heat pump is probably about 20 years old and on its last legs. Newer ones are amazing. We lopped $40 off of our electricity bill each month in the winter and $20 in the summer after we replaced ours. It pays for itself after a few years.

From what I understand, cold weather air source heat pumps are relatively new to the market, at least in the US. Previously they were designed more for cooling loads and were essentially space heaters with an COP of 1 in cold weather. Many manufactuers seem to offer warm and cold climate models. For example, pulling a random manufactuerer, Mitsubishi brands their cold climate line "Hyper" and specs out much better efficiency down to -13F temperatures.

My HVAC is utter crap ≠ HVACs are crap. This is a great example of a worthless anecdotal comment that distracts from the point. Give us some more detail like model number or install date? Is it a modern unit not coming close to its advertise performance? Is it appropriately sized for your condo?

A heatpump blows warm air not hot. Most people expect hot air from their vents and so are confused by not getting it. My heat pump in Iowa worked just fine to keep the house comfortable down to 14F (the system automatically switched to backup heat colder than that). Something is wrong with your system if it can't do that. I couldn't begin to guess what though.
