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?
It’s as noisy as an air conditioner. Because it is an air conditioner — just run in reverse. Some AC compressors are noisier than others depending on manufacturer and quality.
13 year old heat pump owner here. It sounds like a normal AC running outside. It gets a bit loud in certain moments when it runs some exhaust cycle - not sure of the term for it - but that just happen sporadically here and there and lasts no longer than a few seconds.
The “exhaust cycle” is defrost. When running in winter heat pump mode the outside coils will freeze over and must be periodically defrosted by warming them back up, else the system will stop moving heat effectively.
Varies by heat pump but some simply have a valve that self recirculates the refrigerant without entering the house, as all the compressor power turns into heat work to melt the ice, and is also why they get noisier.
I moved into a place with a heat pump for the first time recently and mine is definitely noisy, or more noisy than I would prefer. It’s not terrible when you’re inside near where it is but it is noticeable. It’s also around 10 years old and I believe newer ones are supposed to be quieter.
Heat pumps only last about 15 years so yours may be noisier due to wear and age. I just had a really old one replaced and my new one is a lot quieter.
That’s what I’m thinking, it also may not be installed very well which could be a factor. It’s not quite level, which is supposedly not good for them. I’m planning on replacing it within the next year or three depending on budget and how well it holds out. It seems to work great otherwise, it definitely is much more efficient than anything I’ve had previously.
We just got 2 new Carrier Infinity 24 heat pumps and I don’t think I’ve ever heard them running (except for the fan pushing air through the ducts, but that’s part of a traditional furnace too). It’s an expensive system that is advertised as being particularly quiet, and I think they deliver - I haven’t noticed any change in noise levels. One of them had an issue for a while so we ran the backup gas furnace instead, and I couldn’t tell the difference between the one that was using the heat pump and the one that was using gas.
So it’s possible to get a quiet heat pump, depending on the model.
I had a heat pump and you could barely hear it outside. I had to be within 10ft to hear it running. It could be an age thing too. Mine was installed within the past 3 years, so that probably helps too.
