Behind our two-family house is the air-to-water heat pump. Our new neighbors (three-family house) are very nice. The neighbors living on the ground floor are experiencing their first winter in the new building and hear the air-to-water heat pump running at full capacity.
They find it quite loud, especially in the evening when it operates at subzero temperatures (understandable since the house is being heated).
The heating engineer said that the air-to-water heat pump can be "turned down" during the evening or night hours to reduce noise, but he advises against this because
1 - The house cools down
2 - The air-to-water heat pump risks icing up since the heating elements are also turned down
What do you think about this? Are there any acceptable decibel levels?

Hello,
unfortunately, this is an inherent issue with these systems. At night during winter, they make a lot of noise.
However, the noise is unnecessary since below -5°C (23°F) they will operate purely as electric heaters anyway. The fan noise then just serves as a psychological comfort.
Honestly, I don’t really understand why you run them at night (even though almost everyone does). The efficiency of these heaters depends directly on the outside temperature. The higher it is, the better. So especially in winter, heating should ideally be done during the day. At night, the system should actually be able to stay off if your house is properly insulated.
I know almost no one does it this way... but at least that was the original intended use of these systems.
Best regards,
Andreas

hmm no idea

What exactly is supposed to freeze there??? The refrigerant??? 😉
When the unit is running, the outdoor unit gets colder because it is supposed to extract heat from the environment.
Sure, in freezing rain, a stationary fan might get stuck, but that’s more of an exception, right?
