A central air conditioner combines the evaporator, condenser, and compressor in a single unit that is placed on a roof or a concrete slab near the foundation.
This is a good choice for houses that do not have ductwork. The ductless, mini-split systems combine an outdoor compressor and condenser with one or more indoor air-handling units.
These are the most common types of AC units for single rooms. All of the components are enclosed in a single box with a single thermostat gauge.
This is similar to a window system, but it can be moved from room to room. It's self-contained and freestanding on the floor so you can move it from room to room or apartment to apartment.
Hybrid type of AC unit systems alternate between burning fossil fuels and using electricity to save money and energy while running your system. In the summer, the heat pump works as it normally does, pulling heat from your home and distributing it outdoors.
As a newer method of heating and cooling, geothermal technology is able to extract the heat from below the ground and transfer it into your home.
