A plenum is a box or chamber in a ventilation or air conditioning system where the air ducts connect 🔧 It helps distribute air evenly through all the ducts or collect it back so the system works efficiently and quietly 🤔 If there’s no plenum: Air will blow stronger through some ducts and barely reach others; The system will be noisier; Cooling or heating efficiency will drop; Vibrations and air leaks may appear. #plenum #hvactech #hvacservice #hvacproject #ventilationtips #LAhvac #LosAngelesHV
