Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or fan coil units. A larger air handler that conditions 100% outside air, and no recirculated air, is known as a make...
As is the case with mini splits, a central air system works by circulating refrigerant between the indoor unit and an exterior condensing unit. A chemical refrigerant circulates through the system, absorbing heat and humidity from indoor air and releasing it outside. Advantages of Central Air ...
