All of them? Sure, some were clearly rattly old things with knackered bearings, but they are not silent and stick out like a sore thumb when they click on at night. However, in the daytime, they get drowned out by the general din of life.
But im sure I’ll be told my experiences are wrong.
I lived in a campsite with an old 9kw heat pump and I couldn’t tell if it was on from the other side of the garden (which was as long as the house). Anything that is mechanical and moves got a chance of making a noise but it doesn’t mean all of them do. We also had one inside the house for the hot water and when that was new I had to open the door to the utilities room to even know it was on.
maybe i got lucky to somehow hear them over my tinnitus. and no, if you live around them long enough, its not just a fan spinning (which will get noisy over time when they get manky and imbalanced, which in turn causes secondary vibrations). personally, i prefer air to air heatpumps i had when i lived in nz. not the noisy bastards i put up with in sweden.
that said, despite my hearing loss and tinnitus, i can pick up on annoying sounds nobody notices until i point them out.
Something wrong with whatever heatpumps you’ve seen.

All you can hear is a fan spinning.

I’ve only experiences the air to air heatpumps in aus and nz. I though sweden used the same?
Maybe, but i never came across them.
