Services Ventilation

Ventilation and fresh air systems

We sell and install ventilation and fresh-air systems in shops, offices, restaurants and industrial premises across mainland Portugal. They take out the stale air and bring in fresh air from outside.

  • The air inside becomes fresh air.

    It is not the same air going round and round. The heavy air of late afternoon goes out, the smells go with it, and that shut-in feeling stops turning up. In a business with people in it, that is what gets everyone through the whole afternoon.

  • Less moisture and less condensation.

    The steam made inside goes out with the air instead of staying. The walls and the windows catch fewer drops, and the corners stop growing mould.

Ducting, installed by us.

  • The ducting is built for the place it goes.

    We install ventilation ducting, in galvanised sheet or pre-insulated panel. The trims and the supports are made for the place they go: a low ceiling or a beam in the way changes the whole route.

  • Warehouses, industrial units and industry.

    Ventilation and extraction for warehouses and industrial units, where ceilings are high and the air has a lot of space to travel before it is replaced. The airflow is worked out from the volume of the building, not the square metres of floor.

We work in your home and your business.

How we work.

  1. We look at the space

    We go to the site and look at where the air comes in and goes out today, how many people are in there and what goes on.

  2. We propose and quote

    We tell you what we are proposing to install and why, in words that make sense. You end up with a fixed price, in writing.

  3. We install and balance

    A clean job, on the agreed day. At the end we put everything to work and balance the airflows, room by room, before we leave.

An example of a real job

After

The same roof parapet, with two runs of new aluminium-clad pipework

  • The new aluminium ductwork feeding the air handling unit
  • Wide view of the roof with the new circuit and the ducting installed

This is not a quote: the team confirms everything with you before there is a price.

Questions we are often asked.

Air conditioning cools or heats the air already in the room, in a closed circuit. Ventilation swaps the air: it takes out the stale and brings in fresh air from outside. A full room with air conditioning ends up cool and stuffy at the same time. It is missing the second half.

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 do is designed for premises open to the public. Shops, offices, restaurants, gyms. For homes, talk to us and the team will confirm what it 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.

Yes. The equipment we supply and install carries a three-year warranty. After the job we are a phone call away for any questions that come up.
