This project was accomplished by Denair HVAC NYC in the shortest time. We furnished and installed two air curtains with door switches, exhaust fans, supply and returns grilles, diffusers as well as duct heaters, thermostats and drip pan with leak detectors. We also produced and installed stainless steel ductwork with all associated accessories and volume and draft back dampers. At the end of the project we performed system start-up and we kept the equipment under our maintenance for another year to make sure that HVAC system is working at peak performance efficiently.
