When considering an air source heat pump for your home, noise concerns often top the list of questions. Modern heat pumps typically produce between 40 and 60 decibels of sound during operation, comparable to the ambient noise in a quiet library. To put this in perspective, an everyday conversation occurs at around 60 decibels, making most quality heat pumps relatively unobtrusive.


Factors Affecting Noise Production


Several elements influence how much noise your air source heat pump will generate:

Installation quality plays a crucial role in sound management. Professional installers can position units optimally to minimise noise impact. The location of your unit matters significantly; placing it away from bedrooms and living areas reduces the perceived noise.


Heat pump technology has advanced considerably, with manufacturers now designing units specifically for quiet operation. The newest models incorporate sound-dampening technology and improved compressors that work efficiently without excessive noise.


Solutions for Noise Reduction


If sound remains a concern, several effective solutions exist:

Acoustic enclosures represent one of the most effective noise-reduction options, potentially reducing sound levels by up to 32 decibels—effectively cutting perceived noise in half. These enclosures can be customised to match your home's aesthetic while providing substantial sound dampening.


The strategic placement of your unit makes a significant difference. Installing your heat pump on a noise-absorbing surface or using anti-vibration mounts can further reduce operational sounds.


The Quiet Reality


The truth is that modern air source heat pumps are remarkably quiet compared to older heating systems. Many homeowners report that after installation, they barely notice their system running. As technology continues to improve, heat pumps are becoming even quieter while maintaining their exceptional energy efficiency.


By choosing a quality system with proper installation, you can enjoy comfortable, sustainable heating with minimal sound disruption—making air source heat pumps an excellent choice for environmentally conscious homeowners seeking peaceful living spaces.

Air Source Heat Pumps: How Quiet Are They?

By Charlie Clark • June 6, 2025
Noise issues are frequently the most important consideration when choosing an air source heat pump for your house. When operating, modern heat pumps usually generate noise levels of 40 to 60 dB, which is similar to the background noise in a quiet library. To put this into perspective, most high-quality heat pumps are not really noticeable because normal conversation takes place at about 60 dB.

Air-source heat pumps have completely changed the way we think about heating and cooling in homes in terms of energy efficiency. These amazing devices deliver up to four times as much heat energy as they need in electrical energy, transferring heat instead of producing it. However, what if you could increase the efficiency of your heat pump system even further? Thermal curtains are useful in this situation.
