Hey guys!
Did you know that ventilation it's a crucial part to avoid mold or other worst pathologies on walls and ceilings?
To avoid those pathologies, nowadays it's possible to install a heat recovery air unit to recirculate the air on our houses or building services.
It's also possible to connect it a VRV (variable refrigerant volume air conditioning) unit, to perform not only air recirculation, but also climatization.
Nowadays, Portugal have strict legislations that obligates all the new buildings to have ventilation in order to improve the quality and confort for building users.
What about your countries?
Do you also have or do you know someone who has those issues?
