Can heat pump and air conditioning covers effectively minimise engine noise?

The growing use of heat pumps and air conditioning systems in households has highlighted the issue of noise pollution stemming from these devices, causing inconvenience for users and sometimes affecting nearby neighbours. While modern devices are progressing towards improved discretion, many users seek solutions to mitigate the acoustic disturbances caused by their installations. You’re asking about the acoustic performance of Outsteel covers. Here are your answers.


Aesthetics and acoustics - two different approaches 

It's crucial to differentiate between aesthetic coverings (such as air conditioning covers) and acoustic boxes. Products labelled as "acoustic" or "anti-noise" undergo distinct design and aesthetic considerations, often accompanied by a higher cost compared to conventional coverings. Subject to specific standards and laboratory acoustic tests conducted under controlled conditions, these products offer users measurable noise reduction. Examples include sound screens, anti-noise walls, or boxes lined with sound-insulating materials placed in front of technical units to absorb and control noise propagation. These installations are typically bulkier and visually distinct. If noise reduction is a primary concern, ask the heat pump or air conditioning unit supplier about their commitment to this aspect.


Outsteel - aesthetics and protection first 

Outsteel prioritises aesthetics and device protection in its six models of heat pumps and air conditioning covers. The focus is facilitating device integration into the environment through a robust and durable design. Importantly, none of Outsteel's models amplify the operating noise of the engine or produce a resonance effect. While there may be a slight reduction in motor and/or fan blade noise in certain situations, the primary function of these models is to dress and protect technical units while ensuring optimal operation.

Tips for Reducing Operating Noise

For those prioritising sound volume, begin by selecting a heat pump or air conditioning unit designed for minimal noise. Manufacturers have made substantial improvements in recent years, resulting in quieter devices. To further minimise noise impact:

  1. Choose the device's location carefully to reduce noise pollution for both yourself and your neighbours(do not install the device under a window, do not direct the outdoor technical unit towards your neighbour, leave space with the wall, avoid corners, take advantage if possible of "obstacles" such as shrubby hedges, low walls, etc.) 

  2. Follow the manufacturer's installation recommendations, incorporating appropriate anti-vibration systems or silent blocks.

  3. Maintain the heat pump or air conditioning unit according to recommended guidelines.

Finally, it is strongly recommended not to customise or modify heat pump covers, as these solutions are designed to optimise air flows and altering them could compromise device functionality and accelerate wear on specific parts.
