Do you have a heat pump? Is it noisy?

Riffing off the earlier post about heat pumps in cold weather (lemmy.world/post/10270502), how much noise does your heat pump make?

We’re sandwiched between houses with traditional AC units and in the summer the noise level from each is oppressive. Would I be producing the same amount of noise, year round, if I install a heat pump?

EDIT: the AC units to either side of us are old (at least 10 years) and probably cheaper models. Maybe newer/better ones are quieter?

fritata_fritato,

Heatpumps are in par with AC. I’m noise sensitive dye to poor hearing and sometimes turn it off to help me hear better.

Drusas,

Mine isn't especially loud but my nextdoor neighbor's is.

At my mom’s place — air-source heat pump, double-paned windows — I can’t hear the thing at all from inside the house, and can only hear it if I go on the side of the house where it’s operating, which doesn’t get a lot of foot traffic. You can hear the fan there.

Generally, I haven’t heard people complaining about it in the US. I have seen some people talk about it recently in the UK, which is in the middle of a push to transition to them, and I’m wondering if that’s because townhouses are more-common there, with houses packed closely together.

I understand that you can get noise-reducing enclosures:

There are also water-source heat pumps. I don’t know how the noise differs, but I’d bet that it’s quieter, because you’re moving water through a pipe rather than a lot of air. However, their installation cost is considerably higher (though their energy efficiency is also higher).

Hello_there,

I talked to a tech about it. His advice was that it depends on the type. Heat pump water heater is about sound of a stove exhaust fan, with a higher pitch. No bass.
Heat pump for room heating is lower pitch. Not bassy. But there are regs in some cities about how close to property lines they can be.

PonyOfWar,

I have one a drinking water one in the basement. When I’m in the basement, it’s fairly audible, otherwise can’t hear it at all.

MooseLad,

We have a heat pump. It’s a little louder in the winter, but not by much. It’s very quiet other than the odd hissing sound it makes when defrosting the unit.

uint32,

Mine is not bearable from the inside and only hearable on the same side of the house, but I guess it depends heavily on the model. I. The summer it only runs for hot water - maybe 4 times a day.
