All heat pumps have a sound rating number

The lower the number the quieter the heat pump

All municipalities have a growing concern surrounding noise pollution and are regulating the amount of sound that mechanical equipment, including heat pumps, can emit.

Accutemp’s policy is that the outdoor unit must be located in the quietest location for all
concerned - most importantly, the neighbours.

Sound levels are highly subjective.  What is quiet for some people could be noisy for others.

The HVAC industry has a standard numbering system for sound rating numbers, rated in accordance with ARI standard 270 section 5.3.6

A typical sound rating number for a 3-ton heat pump would be 69 - 76.

The sound that the outdoor unit makes is directly related to the volume of air and the performance of the indoor coil.  Poor air flow over the indoor coil results in a high head pressure condition and will directly contribute to a noisy outdoor heat pump.
