🚀 "The time for being simple technicians is over. From now on you are all engineers, degree or not. You must be able to design, model, calculate, install, start and maintain all HVAC, AC, ventilation and heating equipment; in short, all HVAC.

This is the mindset we're going to develop right now. You're able, we're able. Alone we are strong; together we are unstoppable. »

There you will see the main elements of the system:
• the entrance of new air
• filtration
• the energy retriever
• vacuum and blow fans
• hot and cold batteries
• electrical resistances

• the regulation shutters
