How can we support the growing use of air conditioning systems and heat pumps while preserving harmony in our buildings and outdoor spaces?
This is one of the questions addressed by William Danizet, founder and CEO of DECOClim, a guest on Focus Business, hosted by Thierry Cabannes and published on LeFigaro.fr.
The interview offers an opportunity to share his perspective on market developments, the expectations of HVAC professionals and the challenges of integrating equipment into its surroundings – areas in which DECOClim has built expertise since 2013.

Integrating outdoor units: A challenge beyond aesthetics
As air conditioning systems and heat pumps become more widespread, outdoor units are increasingly visible on building façades, balconies, terraces and in gardens.
While these systems provide thermal comfort, they also raise questions of architectural integration, particularly in apartment buildings and settings subject to aesthetic requirements.
William Danizet highlights this shift during the interview: a successful installation no longer depends solely on technical performance, but also on how well the equipment fits into its surroundings.
In some jointly owned residential buildings or municipalities, architectural requirements can affect installation conditions. Outdoor unit integration should therefore be considered at the design stage rather than after the equipment has been installed.
For William Danizet, this challenge reflects a broader transformation of the market as equipment becomes more common and expectations evolve.
A vision shaped by hands-on experience since 2013
When William Danizet founded DECOClim in 2013, solutions specifically designed to conceal outdoor units were still relatively uncommon.
He recognised a need and chose to address it alongside HVAC professionals, convinced that visual integration must go hand in hand with the equipment's operating requirements.
This collaboration with installers helped shape DECOClim's louvred air conditioner covers, designed to combine an attractive finish with proper airflow.
This focus on equipment performance also led to a pressure-drop study officially documented by a judicial officer, aimed at measuring the effect of DECOClim covers on airflow.
Over the years, conversations with professionals and real-world installation conditions have guided the evolution of the product range.
Asked by Thierry Cabannes about the company's strengths, William Danizet sums up this philosophy:
“We are pioneers. We always try to stay one step ahead and listen closely to what is happening in the field.”
This practical understanding is now central to his vision: offering solutions suited to real-world needs without setting aesthetics against technical requirements.
Better equipment integration as the market evolves
Beyond DECOClim's growth, William Danizet's appearance on Focus Business highlights a conviction that has guided him since the company's early days: integrating technical equipment should be part of the wider conversation about homes and the built environment.
Neighbourhood concerns, shared-building requirements and architectural harmony are far from secondary issues. They can influence whether an installation is accepted and call for appropriate solutions from both HVAC professionals and manufacturers.
As William Danizet puts it in the interview published on LeFigaro.fr:
“We are not trying to hide the energy transition; we want to integrate it more effectively into our everyday surroundings.”
This conviction goes beyond air conditioner covers alone and reflects a commitment to better integrating equipment into buildings and landscapes.
Shaped by experience and dialogue with professionals, this vision continues to guide William Danizet as DECOClim develops in France and internationally.
Key takeaways
William Danizet's appearance on Focus Business in Le Figaro highlights an increasingly important challenge as air conditioners and heat pumps become more widespread: integrating their outdoor units into the surrounding environment.
Beyond aesthetics, this requires consideration of the equipment's technical constraints, occupants' expectations and the architectural characteristics of buildings.
Since 2013, DECOClim has supported this evolution by developing outdoor unit covers in close collaboration with HVAC professionals.
An approach built on one conviction: integrating technical equipment more effectively also helps preserve harmony in our living environments.
