Services Ventilation

Ventilation and fresh air systems

Air conditioning treats the air that is already there. Ventilation brings in fresh air from outside. In a space with people, you need both.

  • Extracts stale air

    Stale indoor air — with carbon dioxide, humidity and odours — is removed from the space through extraction grilles connected to the duct, and released outside.

  • Brings in fresh outside air

    Exhaust without supply is not ventilation: if air comes out and no more comes in, the space falls under negative pressure and doors become difficult to open. Air intake is half of the system.

  • It carries away odours and moisture with the air that leaves

    Don't mask them, remove them. Steam from the kitchen, work products and perspiration escape with the flow, and the windows stop fogging up.

  • Sized by occupancy, not just floor area

    Airflow is calculated from occupancy and how the space is used. Two rooms with the same square metres can require very different flow rates.

We work in your home and your business.

How we work.

  1. Visit and flow calculation

    We go to the place and see how many people come in, how long they stay and what is done there. This is where the flow comes from, and not from the square metres alone. You leave with the fixed price, in writing.

  2. Installation of ducts and grilles

    Fans, ducts, extraction and intake grilles, with the route designed to see as little as possible. clean installation work, on the agreed day.

  3. Rehearsal with the working space

    We measure with everything turned on and with people inside, because that's how the space will live. If there is a lack of flow in a place, we fix it before we leave.

Questions we are often asked.

The air conditioner cools or heats the air already in the room, in a closed circuit. Ventilation changes the air: removes the stale air and brings in fresh air from outside. A full air-conditioned room feels cool and stuffy at the same time — the second part is missing.

From what people say. Heavy air after a while, smells that linger, foggy windows, heavy head at the end of the afternoon. With the air conditioning working and the sensation remaining the same, the problem is the air, not the temperature.

Something, yes, and that's why the two work together. There are systems with a recuperator that use part of the heat or cold in the air that leaves.

The ventilation we provide is designed for public spaces — stores, offices, restaurants, gyms. For housing, talk to us: the team confirms what they can do in your case.

In most cases, yes, in phases and outside of busy times. Agree before you start, so there are no surprises halfway through.

It's the same principle: changing the air instead of cooling it. The acronym VMC is used mainly in housing, with ducts throughout the house. In commercial spaces, we talk about air extraction and renewal, which is what we do.
