You’ve probably come across air-conditioners and have heard the ‘fan-coil’ unit whirring away on a hot day. Heat pump systems are similar and care should be taken when choosing where to locate a heat pump, for example, away from bedrooms or places where the noise might disturb others.

Some heat pumps also come with a noise reduction function where they can be programmed to reduce the speed of the ventilation fan between certain hours. In most instances, this function will not be necessary, but it’s an option in case the unit is installed close to a bedroom window.
