Certified performance rating data from virtually any air-to-air, air-to-water, etc., system sold in North America is available here [1]. This includes capacity, COP, and sound data. It also includes integrated performance rating metrics like SEER, HSPF, IEER, etc.
As-engineered and as-installed/configured figures have the potential for a wide spread. Both are useful, but as a homeowner, I’m interested in seeing my as-installed figures more than the manufacturer or test lab’s figures.
As a shopper, I’d want to see a nearby house’s figures as-installed by my prospective contractor.
A big factor for the total energy consumption besides the heatpump is the rest of the heating system.
For our house the yearly energy consumption of the heatpump is around 1.4MWh/y (for floor heating, warm water and cooling of the bedrooms in summer;this number is reported by the heatpump control system) but the hole heating system including all the pumps and so on is 2,55MWh/y.
It's important to note that those ratings are all tested under specific conditions that includes a rather short (~3m IIRC) lineset and other parameters of installation that in the field can lower the capacity as more energy goes to the pumping of the liquid refrigerant. Particularly the lineset length.
Also, the testing varies between "traditional style heat pump" and inverter driven "VRF" equipment.
That's not to say that the AHRI information isn't useful, but the numbers can be a little subtle to get to an apples to apples comparison and you should have a selection done based upon some real estimated line lengths and installation conditions.
