When installing an air conditioner or a heat pump, the outdoor unit often becomes one of the only technical elements still visible on a façade, balcony or in a garden.
To improve its integration, many people consider a custom AC cover, assuming it is the most suitable solution.
Custom-made solutions do offer advantages. But in most cases, a well-designed modular solution can deliver an equally precise result, without the constraints of a bespoke product.
Before choosing, it is worth understanding what the idea of a custom AC cover really means.

The benefits of a custom AC cover
A custom AC cover is generally considered for three reasons: precise sizing, aesthetic customisation, and handling specific installation constraints.
- Adaptation to exact dimensions: Every installation has its own characteristics: height, width, depth, brackets, wall clearance. A custom-made solution theoretically allows centimetre-perfect adjustment.
- Design customisation: Some manufacturers offer specific patterns or cut-outs. The cover then becomes a visible element, sometimes embraced as a decorative choice.
- A solution for unusual configurations: Corner installation, significant depth, a unit visible from several angles… in some cases, a dedicated product may seem relevant.
However, like any bespoke product, this approach often involves a higher price and longer production times. And one essential criterion is sometimes underestimated: airflow.
Airflow: a criterion that should not be overlooked
One of the attractions of a custom AC cover is the freedom to choose the design: custom patterns or graphic cut-outs can be visually appealing. But a heat pump or air conditioner works first and foremost thanks to controlled airflow. And the design choice can directly affect that airflow.
A very graphic pattern may look visually open while actually creating a series of obstacles that restrict and divert the air. The airflow then becomes uneven.
By contrast, a louvred design naturally supports the movement of air. The openings are oriented in a way that is consistent with how the unit operates, encouraging smooth and continuous airflow. From a technical point of view, this design is particularly relevant for preserving the performance of the unit.
Custom-made solutions are attractive because of their design freedom. But an AC cover must first and foremost preserve airflow, which is essential for both comfort and long-term equipment durability.
Custom or modular AC cover: which solution should you choose?
While a custom-made solution allows extensive personalisation, it is not always necessary to achieve a precise and technically consistent result.
Between a fully standard product and a bespoke build, there is a middle ground: the modular AC cover. This solution is based on a range of sizes and accessories that allow the cover to be adapted to the real constraints of the installation.
This is exactly the logic behind the DECOCLIM range. Structured around 11 sizes, from XS to XXL+, it covers both compact units and the largest heat pumps. It also offers 10 colours suited to built environments.
Adjustment accessories make it possible to fine-tune height and depth according to the installation, while ensuring a clean and consistent finish.
In the vast majority of cases, this modularity delivers a result that is just as precise as a custom heat pump cover, while keeping both budget and lead times under control.
Check your air conditioner dimensions before choosing
Before making any decision, it is essential to measure:
- the total height (including brackets)
- the actual width
- the depth of the unit only
- the total depth back to the wall
Depth is often the criterion that makes people think of a custom-made solution. However, some modular solutions allow the installation to be adjusted by up to +40 cm in depth, without changing size. This is notably the case with our “depth rails”, which add up to 40 cm to the minimum depth of our AC covers. Discover this accessory here in white (RAL 9010).
Precise sizing helps achieve a more harmonious integration and ensures your installation works properly. To find the most suitable model for your project, without resorting to a bespoke solution, use our configurator below.
Wood or aluminium: choosing based on your environment
The material plays a role in visual integration.
For a natural or landscaped environment, a wooden AC cover brings warmth and discretion.
For a contemporary façade or urban setting, an aluminium AC cover offers durability and architectural consistency.
Which professional can help install my AC cover?
In many cases, a modular AC cover can be installed by yourself when the outdoor unit is easily accessible. In certain specific situations, such as a high-level installation, rooftop installation or a hard-to-reach façade, calling in a professional helps secure the installation.
Ideally, however, the cover should be included from the moment the air conditioner or heat pump is installed, directly in the installer’s quote, ensuring a coherent and optimised finish from the outset.
To find a professional familiar with this type of installation: find an AC cover installer.
Why a modular solution works for most projects
A bespoke solution remains relevant in some very specific configurations. But in most projects, the goal is not to obtain a one-off product, but to find a solution that is genuinely well suited to the installation.
A structured range, combined with adjustment options and a choice of colours that fits the environment, already covers the vast majority of situations.
Before opting for a bespoke product, it is therefore worth assessing whether a well-designed modular AC cover already fully meets the need.
FAQ: custom AC cover
Is a custom AC cover always necessary?
No. In most cases, a well-sized modular AC cover provides a precise result without requiring a bespoke product.
What is the difference between a custom AC cover and a modular AC cover?
A custom-made cover is produced specifically for one installation. A modular cover is based on several standard sizes and adjustment accessories.
Can an AC cover affect how the unit operates?
Yes, if the design does not properly respect airflow. The cover must preserve air circulation around the outdoor unit.
How can I check whether an AC cover is compatible?
You need to measure the total height, width, the depth of the unit only, and the total depth back to the wall.
Can I install an AC cover myself?
Yes, if the unit is easily accessible. If the installation is high up or hard to reach, it is better to call in a professional.
Should I choose a wooden or aluminium AC cover?
Wood integrates well into natural environments. Aluminium is particularly suitable for contemporary façades and urban outdoor spaces.
