Best practices call for placing the outdoor unit away from windows and adjacent buildings, and install the unit on a solid base such as a concrete pad or block with a vibration-absorbing mat to reduce noise. When having a heat pump installed, ask your contractor about the best location for the outdoor heat pump unit and how that placement may impact the noise levels of the system. Reduce noise by looking for these features when purchasing a heat pump: The fan model and speed, as well as the airflow and pressure flow of the system, affects the level of noise that the fan will produce. Noise is created by the fans and compressors. This rating is specified by most manufacturers on the system’s technical specification sheet, and represents the sound, measured in decibels, generated by the heat pump when it is working at full capacity.

Heat pump indoor units generally have sound level ratings between 18 and 30 decibels.Įach heat pump system has a different sound level rating. Some ultra-quiet models attain lower sound level ratings. On average, most modern heat pump outdoor units have a sound rating around 60 decibels, equivalent to a moderate rainfall or normal conversation. Both the indoor and outdoor components of a heat pump make some noise.
