Ventilation and air quality in Marbella

Mould in the wardrobes, condensation on the windows, a musty smell when you open up after winter. Sea air and sealed, shut-up houses cause all three. We fit ventilation and dehumidification that deal with the cause.

Dehumidification

For basements, wine rooms, garages, indoor pools and homes that sit empty, a fixed dehumidifier holds the humidity at a set level and drains itself.

In lived-in rooms, the dry mode on a correctly set-up air conditioner is often enough, and we’ll tell you if that is the case.

Heat-recovery ventilation

Modern windows seal a house so well that stale, damp air has nowhere to go. A heat-recovery unit brings in filtered fresh air and extracts the old, passing one across the other so you keep the cool in summer and the warmth in winter.

It runs quietly all day and all night.

Filtration

For pollen in spring and dust during a calima, we fit fine filters and purification modules to ducted systems, or standalone units where there are no ducts.

Extraction for kitchens and bathrooms

Bathrooms without a window, internal utility rooms and commercial kitchens need extraction that actually moves air to the outside. We replace tired fans, fix ducts that end in the ceiling void and design extraction for restaurants and bars.

Duct cleaning

Ducted systems collect dust and, in humid houses, mould. We inspect with a camera, clean and disinfect the ducts and grilles, and seal any leaks we find.

Questions people ask

Why does my house smell musty after the winter?

Because it has been shut for months at 70 to 80% humidity with no air moving. Mould grows on the walls, in fabrics and inside the air conditioning. Background ventilation or timed dehumidification while you are away prevents it.

Is the dry mode on my air conditioner enough?

For a lived-in room, usually. For a basement, a closed-up house or a room without a unit, no. We measure the humidity over a few days before we recommend anything.

Will ventilation make the house hot in summer?

Not with heat recovery. The incoming air is cooled by the outgoing air on its way through, so you get fresh air without throwing away what the air conditioning has done.
