Technical Clicking when adjusting climate

[Joelgreenbaum]

Hi, when I turn my climate control on or off I can here a click sound from behind the climate control unit. When I adjust the air temperature to hot or to cold, again but I hear 2 clicking noises coming from behind the climate control. It's intermittent. Does anyone no if this is normal or if not what the fault is? The aircon and heater both work. Thanks

Hello,

I'd say it's the compressor that is turning on/off. But not sure about the exact sound.
