Controlled mechanical ventilation, more commonly known as CMV, is an essential element in ensuring good air quality in your home. But how do you know if your CMV is working properly?
In this article, we offer you a simple guide to testing the efficiency of your VMC using a simple sheet of paper. You’ll also find practical advice on how to manage humidity in your home and improve your day-to-day comfort. So, are you ready to take the test? Follow the guide!
VMC, an essential ally in controlling humidity in your home
Excessive humidity in a dwelling can cause major material damage, such as deterioration of walls and mold growth. It can also have a negative impact on occupants’ health.
To alleviate this problem, ADEME recommends the use of a Controlled Mechanical Ventilation (VMC). This tool not only makes it possible toevacuate polluted air from your home but also to prevent dangerous fumes such as carbon monoxide.
What’s more, an efficient CMV helps you save on heating costs by keeping humidity levels between 40 and 60%. Here’s how to check that it’s working properly, and how to maintain it.
To check whether your VMC is working properly, a quick and simple test can be carried out using a sheet of light paper. Place the latter in front of your VMC grille. If it sticks, this means that indoor air is being drawn outside, indicating that your system is working properly.
On the other hand, if the sheet falls to the ground, it’s time to consider a more thorough cleaning or inspection for electric models. For humidity-controlled systems, point a hair dryer at the air outlet after removing the grille. If the grille closes automatically, your VMC is working properly.
Regular maintenance of your VMC: instructions for use
To maintain the efficiency of your CMV, regular maintenance is necessary. Start by removing the grates and cleaning them with white vinegar. Then vacuum the hole to remove any build-up of dust or debris. If your VMC is electric, don’t forget to turn off the electricity before starting these operations.
Once the grille is clean, make sure it is before replacing it. You can air-dry or use a hair dryer to speed up the process. To avoid excessive humidity in your home, this maintenance should be carried out at least once a quarter.
In addition, remember to check ventilation ducts regularly to make sure they are not blocked, which could compromise the proper operation of your CMV. Finally, if you notice persistent problems such as a or unusual noises, don’t hesitate to call in a professional for a thorough inspection and repairs if necessary.
