Types of AC Units
Window Air Conditioners are a type of unitary system that can be easily mounted on a window or through a hole in an exterior wall. All the refrigeration components are in one compact box, making them a convenient option.
The condenser coils are located on the outdoor side, where the unit ejects heat out, while the evaporator coils are on the indoor side, where the appliance blows cool air into the room. Window ACs also come in various sizes, from small units that cool a single room to large ones that are capable of cooling an entire floor.
Some very large units are even capable of cooling an entire home, if it's a single-story small house.

Window Air Conditioners
Window air conditioners are a popular choice for cooling individual rooms or small areas, and they're often referred to as unitary systems because they're a self-contained unit that can be easily mounted on a window.
These units have all the refrigeration components in one compact box, with the condenser coils located on the outdoor side where they eject heat out of the unit.
The evaporator coils are on the indoor side, where the appliance blows cool air into the room, making them a great option for rooms with limited space.
Window ACs also have a tray on the underside of the compact box where the moisture that condenses on the evaporator coils drips, so it's essential to install them slightly tilted towards the outdoor side to prevent water from dripping onto the floors.
Some window ACs are designed for small rooms, while others can cool an entire floor or even an entire home, depending on the size and layout of the space.

Ductless AC Units are also known as mini-split units and are popular in homes without forced-air HVAC systems. They're perfect for homes with hot-water or steam radiator systems, or electric heating.
Split AC units break the system into two terminal units: the condensing unit on the exterior and the evaporative unit on the interior. The condensing unit contains the compressor, condenser, and fan.
The evaporative unit handles the air cooling and distribution, containing a circulation fan, expansion valve, and evaporator coils.
