Contact ventilacion.cat

You can write to correct a guide or describe a real ventilation, condensation or air-renewal problem. The first contact puts the situation into context; it does not diagnose the property or book regulated installation work. It is not a quote from photographs.

Published contact routes

The portal email is vik@ventilacion.cat. Aleksandr Prokofyev is responsible for the publication.

WhatsApp links open a conversation with +34 633 154 728. The message identifies ventilacion.cat, the page and its language. Assessment journeys add a few short prompts which you may complete, edit or remove. There is no second route or alternative official number.

Editorial corrections

Please include the page URL, the sentence that needs review and, if available, a source that says something different. Terminology corrections, updated official links and real situations that a guide explains poorly are also useful.

Each correction is checked against the source supporting the claim. If the source says less, the sentence is narrowed or removed. No response time is promised.

Describing a real situation

There is no long form to complete. A useful first message often includes:

  • municipality or approximate area and property or project type;
  • the main symptom and rooms affected;
  • the existing system, if any;
  • whether this is a new installation, a refurbishment or an existing-system problem;
  • whole-property project or small isolated repair;
  • general photographs or a short video, only where they add context.

You can start with less. The purpose is to see whether ventilation appears relevant, whether a visit within roughly 100 km of Barcelona may add value, or whether another trade is more appropriate.

What the message does not settle

A conversation is not an official inspection, remote diagnosis, formal design, technical report, certification or installation quote. A photograph cannot reliably distinguish condensation from a leak, rising damp or a building defect.

It also does not confirm that regulated work can be accepted. VMC, heat recovery, whole-property or commercial systems, air conditioning, refrigerant circuits, commissioning and legalisation require the applicable authorised company and professionals to be verified first. That authority is not attributed personally to Viktor.

Photographs and privacy

Send only what is needed to understand the configuration. Avoid identity documents, medical reports, contracts, faces and third-party data. WhatsApp sends nothing until you confirm the message. The privacy policy separates the content you choose to send from the limited page metadata that GA4 may receive only after consent.
