Why professionals trust DECOCLIM — the AC cover that respects airflow

Pioneer of air conditioner and heat pump covers (PAC) since 2013, DECOCLIM has made airflow preservation its top priority.

Because a cover should never affect the performance of a unit, each model is designed to protect and beautify — without compromising efficiency. This constant commitment has made DECOCLIM the benchmark in AC covers and the No. 1 choice of professionals in the field.

1. Independent study on the airflow of DECOCLIM air conditioner and heat pump covers

When technology speaks for itself

“You shouldn’t enclose the unit”, “the motor will overheat”, “it voids the warranty”...

We’ve heard these objections dozens of times. So instead of arguing, we decided to put them to the test.

In December 2023, we commissioned an independent engineering firm to measure the real impact of a DECOCLIM cover on the airflow of various units — under the supervision of a bailiff.

Results:

  • Air-to-air (monosplit) air conditioner: average pressure loss 2.06%
  • Air-to-water pool heat pump: average pressure loss 2.85%

Values perfectly compatible with optimal operation — no overheating, no overconsumption, no malfunction.

“I’ve been installing DECOCLIM since 2015 and never had a single performance issue. They’re the only covers I install with complete confidence.”
— Alexandre D., HVAC installer – Marseille

2. A technical design focused on performance

Persian-style slats and 7 cm spacing: the key to controlled airflow

The secret to preserving airflow? A unique design developed from the start with HVAC professionals to meet their standards of performance and reliability.
Every DECOCLIM cover features:

  • Persian-style slats angled precisely to promote smooth air intake and exhaust.
  • A rear offset of 7 to 22 cm, ensuring natural and unrestricted airflow.
  • A proven one-piece design, free of decorative cutouts or perforations.
  • 8 sizes for an ideal fit with any AC or heat pump model, leaving minimal distance between the compressor and front panel for optimal airflow.

Result: smooth ventilation, preserved efficiency, and impeccable aesthetics.

“A well-fitted cover means a motor that breathes better. With DECOCLIM, I’ve never noticed any performance loss, even in compact installations.”
— Romain P., installer – Montreuil

3. Installers’ testimonials: AC covers tested and approved in the field

7,000 partner installers and hundreds of thousands of DECOCLIM units installed

“I’ve never had a single service call because of a DECOCLIM cover. Customers love the final look.”
Stéphane L., HVAC technician – Aix-en-Provence

“DECOCLIM has become a reflex in my quotes. My clients find it cleaner — and I know the airflow stays perfect.”
Michael V., installer – Le Muy

“On-site, we look for reliable, tested, and easy-to-install products. DECOCLIM ticks all the boxes.”
Loïc C., installer – Lyon

My name is William Danizet. I designed the first air conditioner cover and heat pump cover in France in 2013, more than 10 years ago. Since then, hundreds of thousands of DECOCLIM have been installed across Europe. The key to this success? I created DECOCLIM by working closely with air conditioning and heat pump installers. DECOCLIM is thus the first air conditioner cover and heat pump cover which, in particular thanks to the design of its large shutters, its 7 cm recess at the rear... make it possible to hide, protect and insulate the exterior unit while allowing the outdoor unit to operate with optimal ventilation. Only DECOCLIM is today certified by studies carried out under the control of a bailiff which attest to this performance.
