is a self-contained system that provides both heating and cooling for
particular spaces. However, the RTU HVAC system is different from other HVAC
systems because, in the traditional

packaged unit combining evaporator and condenser
coil, compressor, heat source, and a fan. Produced heat and cold air reach
the desired rooms by registers and ductworks. A question may come to your mind
