Question: I have just bought house and deciding heatpump vs oil. We have an autistic person in the house hold that is very sensitive to high frequency noises and perpetual sounds in general. He is used to an oil furnace turning on and of.

I fear for sound pollution from a heat pump.

Will anyone share their experiences with this? Even just a shuttle humming would be a disaster for our spectrum case.

Can we get a completely silent setup ?

I don’t know whether you can get a completley silent unit, but I can say that our Mitsubishi heat pump does make a high pitched sound while running. Although I am used to it now, I found it annoying until I got used to it. It is very different than the intermittent low pitched rumble of my oil boiler.

Thanks. Yeah I heard others say the same. And that the sound can increase as the system gets older...
