A central air conditioning system utilizes two fans. One is located inside the home and brings cool air in through the ducts. The other, located outside the home, blows onto the condenser coils to remove heat from the air. Without both of these fully working, you won’t have the best cooling possible in the home.

Why is my AC unit so quiet?
Stuff cooling elements down that box and turn on the fan, you get cold air. Much quieter than a “real” AC unit too, because this has no noisy compressor. The point is to blow air across something frozen. It will of course thaw, but the thawing pulls heat from the air, making the air a bit colder.
How does an air conditioner work?
Air conditioner is a sealed system to bring cool pressurized refrigerant through the evaporator cooling coils through your room whereby the air is cooled through a blower. In a typical bedroom split unit, air is pulled in through the evaporator coil and blown out through the lower vents.
