These types of sounds are often the result of the fan blades hitting something that has ended up inside the unit, such as a chunk of ice or another component.
Why are heat pumps so loud in the winter?
During the cold season, the heat pump shifts to defrost mode, and the valve reverses and produces a whooshing noise that lasts for several seconds. After the whooshing sound comes a slightly louder sound from the compressor. The sound is normal and may seem louder during winter since the heat pump works the hardest.
Is a heat pump supposed to be loud?
Both the indoor and outdoor components of a heat pump make some noise. On average, most modern heat pump outdoor units have a sound rating around 60 decibels, equivalent to a moderate rainfall or normal conversation. Some ultra-quiet models attain lower sound level ratings.

The air can produce noise when passing through the heat exchanger, with a variable intensity depending on the pressure. This causes buzzing sounds to be emitted and it's this constant hum that proves to be the most disturbing to homeowners and neighbours.
What is an acceptable noise level for a heat pump?
between 50 and 90 decibelsMost heat pumps produce sound between 50 and 90 decibels. The higher the decibel rating of the heat pump, the more noise it will make during normal operation. The quietest heat pumps on the market run as low as 50 decibels, which is equivalent to the sound of a conversation at home or light traffic.
What should my heat pump sound like?
