Do Heat Pumps make a lot of noise?

Modern Air Source Heat Pumps are designed to operate quietly and efficiently, making them well suited for residential properties. While the outdoor unit does produce some sound during operation, today’s systems are significantly quieter than older heating technologies. All heat pumps installed by EPC Improvements are MCS certified and selected to meet strict noise and performance standards. In most cases, the sound level is comparable to everyday background noise, allowing you to enjoy efficient, low-carbon heating without disruption to your home environment.
