What is HVAC commissioning?
HVAC commissioning checks and tunes an installation so it actually works as intended : balancing air and water flows, commissioning AHUs and ventilation, testing control sequences and clearing snags. It is the step that turns a merely « connected » installation into a high-performance one.

What's the difference between air and water balancing?
Air balancing sets the distribution of airflows (AHUs, ventilation, grilles and diffusers). Water (hydronic) balancing sets the water flows (chilled- and hot-water networks, fan-coils) using balancing valves. The goal is the same : deliver the right flow to the right place.

Why balance an installation that is already running?
Over time flows drift, dampers and valves go out of adjustment, some zones become uncomfortable and pumps and fans over-consume. Re-balancing restores comfort and cuts consumption, without major works.
Is a BMS mandatory?
Yes, in many tertiary buildings, under the French BACS decree : for existing buildings, HVAC systems over 290 kW since 1 January 2025 and over 70 kW by 1 January 2030. New buildings over 70 kW have been covered since 8 April 2024.

What does the French tertiary decree require?
Tertiary buildings over 1,000 m² must reduce their final energy consumption by 40% by 2030, 50% by 2040 and 60% by 2050. HVAC commissioning and a BMS are direct, low-cost levers to get there.
Do you operate throughout France?
Yes. Based in the Paris region (Île-de-France), we operate across the whole of France, on tertiary, industrial, hospitality, healthcare and public-access buildings.
Do you offer emergency callouts?
Yes, we mobilise quickly, including for refrigeration and air-conditioning emergencies. An « Emergency? » WhatsApp button is available on the site for a quick callback.
Should high-GWP refrigerants (R404A, R410A) be replaced?
These refrigerants have a high global warming potential and are targeted by the F-Gas Regulation. Depending on the case, we prioritise leak-tightness and maintenance, or retrofitting towards low-GWP refrigerants. We carry out the diagnosis and leak detection.
