How loud is a heat pump?

The sound level is around 45 – 50 dB for most heat pumps, which is about a light background voice. If the unit is being installed against a brick wall you should be fine, if you have a bedroom next to the heat pump you may be able to hear it.

If you suspect your unit is too loud, consider downloading a decibel measuring app on your smartphone to confirm if it falls outside of the expected range. If it is too loud, record a video next to the heat pump that shows how loud it is and share the video with your installer.
