Ventilation and indoor air quality in Valencia
Conditioning well and ventilating badly means paying for cold air and throwing it out the window. The double-flow recovery unit renews your home's air — CO₂, odours, humidity — returning up to 90% of the energy of the air it expels.
We reply in writing — no calls unless you ask for one.
Quick summary
We install double-flow heat recovery ventilation in Valencia from €1,490: renewed, filtered air with windows closed, CO₂ under control and up to 90% of the energy recovered. Ideal alongside climate in renovated homes and premises. WhatsApp: +34 617 307 409.
Why ventilate with recovery and what does it cost?
Modern homes seal so well the air stagnates: CO₂ climbing overnight, humidity condensing on windows, odours that linger. Opening the window works — and expels every euro of climate you paid for. The recovery unit crosses outgoing and incoming air without mixing them: fresh air enters filtered and tempered, and the bill never notices. From €1,490 installed.

Why us
New air without paying for climate twice
The cold stays home
The exchanger returns the outgoing air's energy to the incoming stream — ventilating stops costing climate.
Pollen stays out
Air enters filtered: in spring, the allergy sufferers at home tell the before and after within a week.
Humidity and mould, braked
Condensation on windows and cold corners drops when air circulates at a measured rate.
Quiet and programmable
Flow rates by schedule, night mode and optional CO₂ sensors — the ventilation works alone.

FAQ
FAQ about ventilation
What is double-flow ventilation with heat recovery?
A unit that extracts stale air and brings in filtered fresh air simultaneously, crossing them in an exchanger that transfers up to 90% of the energy — you ventilate without discarding the climate you already paid for.
How much does a heat recovery unit cost to install?
From €1,490 installed with ducts and grilles in a home with accessible routing. In renovations with the false ceiling open the works are minimal — the best moment to decide.
Does ventilation replace air conditioning?
No — they complement each other: the recovery unit renews and filters; the climate heats or cools. Together they achieve what neither manages alone: clean air at the temperature you want, windows closed.
Does it help against humidity and mould?
It is its best weapon: constant renewal evacuates the moisture from showers, cooking and breathing before it condenses on cold surfaces. Mould loses its raw material.
What maintenance does it need?
Filter washing or replacement a couple of times a year and an exchanger check — we include it in our maintenance contracts alongside the air conditioning.
