A heat pump always generates more or less noise depending on its nature, model and age. If you are not alone in being exposed to this volume, you must make sure that it does not disturb your neighbors, as they may complain.

A heat pump generates more or less noise

Of all the heat pumps on the market, the noises generated are varied, and some are silent while others will appear to you noisy.

In any case, always check that the heat pump you have chosen has the NF label, or the Eurovent label.

In general, be aware that indoor units heat pumps installed in dwellings have a sound volume of approximately 22 decibels, while that generated by outdoor units is around 45 to 65 decibels: this volume can be more annoying, especially since the noise generated by a heat pump is continuous.

When does the sound of a heat pump become a nuisance?

Know that the judgment of the Court of Appeal of Paris of September 2, 2014 considered that the noise generated by a heat pump could actually constitute a nuisance, giving reason to a couple who complained about the noise of their neighbor's heat pump, who heated his pool for 8 months of the year continuously.

Thus, to find out if your heat pump generates a noise that could cause noise pollution for those around you, you must take into account the sound volume of your heat pump, related to ambient sound volumewhen it is off.

More generally, be aware that there is a rule setting the threshold volume that you are allowed to generate in addition to the ambient sound volume:

  • From 7h to 22h, you must not cause noise exceeding 5 decibels;
  • From 22h to 7h, this threshold is set at 3 decibels.

Limit noise pollution of a heat pump

To prevent the sound volume of your heat pump from annoying your neighbors or yourself, you can take some precautions:

  • If possible, install your heat pump away from the living areas, windows, and possible party walls that you share with your neighbors.
  • You can isolate your heat pump by placing it in a shell or by installing a noise screen around this one.
  • Instead, place your heat pump high so that the noise does not spread through the floor.
  • Do not install it in a small space such as an angle, as noise will be more important.
