This is one of the most common myths you’re likely to hear about air source heat pumps.
Modern heat pumps are compact, energy efficient and make very little noise.
Independent research from acoustic experts found that heat pumps are about as noisy as a gas boiler or your fridge. And in interviews with those who own heat pumps, residents were more likely to notice the sound of nearby traffic over the sound of their heat pump.
The noise you hear is from the pump’s fan pulling air into the system. If yours is installed correctly by a certified installer, you shouldn’t be able to hear the sound indoors.
