Contributing to the good quality of indoor air, our ventilation systems, like VMC or CTA (Central Air Treatment), must be imperatively maintained to guarantee the good treatment of your air, and therefore, of our health. A poorly maintained ventilation network is a network conducive to the development of microorganisms, which can degrade the quality of our indoor air. Namely, the accumulation of dust in our systems generates energy overconsumption and premature degradation of these.
