How loud & noisy are air source heat pumps?

Air Source Heat Pump Noise

Air source heat pumps (ASHPs) are often perceived as loud. However, modern models are significantly quieter than earlier versions. The actual noise level of an ASHP can vary based on the specific model and the quality of its installation. Ensuring the pump is installed correctly is key to reducing noise emissions. Understanding these noise levels is important for homeowners to determine if an ASHP is a good fit for their living environment.
