Installation of mechanical ventilation in Braine-l'Alleud

Ensure the air quality in your Braine-l'Alleud home

A well-installed ventilation system protects your home from humidity and maintains healthy air year-round. In Braine-l'Alleud homes that have been well insulated and sealed, it is the essential link that many forget to plan for. Avenir Rénovations integrates ventilation from the design stage of the project. Request your quote for the system suited to your home.

Maintenance of a ventilation system in Braine-l'Alleud

A ventilation system is an electromechanical device that requires regular maintenance to maintain its airflow and quiet operation. Here is what this maintenance includes.

Cleaning of vents and filters

Extraction vents (in the kitchen, toilet, bathroom) should be cleaned at least twice a year. On double flow ventilation systems, the filters on the air inlets and outlets should be replaced every six to twelve months depending on the level of outdoor pollution and the presence of pets. A clogged filter reduces airflow and forces the motor to work harder, increasing electricity consumption and noise levels.

Motor and airflow check

The centrifugal motor of a single flow ventilation system generally lasts fifteen to twenty years. An annual check of the airflow at the extraction vents allows for the detection of an imbalance before it becomes a problem. For double flow systems, the annual check also includes inspection of the heat exchanger to prevent any accumulation of condensate or legionella.

Cleaning of ducts

The ducts of a ventilation system accumulate dust over the years and can harbor nests of insects or birds if the exterior grilles are not properly protected. Professional cleaning of the ducts every five to ten years is recommended to maintain the quality of the air being circulated.

Ventilation and air quality in Braine-l'Alleud: indoor pollutants to evacuate

Mechanical ventilation is not only used to evacuate humidity. It dilutes and extracts many indoor pollutants that many homeowners are unaware of in their homes.

Volatile organic compounds

Paints, glues, new floor coverings, cleaning products, and furniture made from wood panels emit volatile organic compounds (VOCs) for months, sometimes years after installation. In a well-insulated and poorly ventilated home, these compounds accumulate to concentrations that can exceed the guideline values for indoor air quality. The ventilation system renews the air and keeps these concentrations at an acceptable level.

CO2 and respiratory discomfort

A family of four produces several kilograms of CO2 per day just from breathing. In a well-sealed house, the CO2 concentration can reach levels that induce feelings of fatigue, headaches, and drowsiness. This is often what occupants of newer homes feel without understanding the cause. The double flow ventilation system with CO2 detector automatically adjusts the airflow to maintain a healthy concentration.
