Riffing off the earlier post about heat pumps in cold weather (https://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?
Like with AC units, there are quiet heat pumps and loud heat pumps.
I would look online for reviews that talk about sound. Look for information about decibels and or sones. A lot of manufacturers publish that info.
You might also want to see if anyone has published anything about the sound your models put out. That way you have a baseline number to compare new unit specs to.
