Types of Systems
There are many system variations, but depending on which part of the country you live in, and the construction of your house, some may be more appropriate for your comfort needs. The most common configuration is called a split system because it requires both an outdoor unit and a unit inside your home. Typically, a split system is composed of an air conditioner, furnace and coil, or a heat pump and air handler. Or it may use a heat pump and furnace, or even an air conditioner and air handler. The opposite of a split system is a packaged unit. Instead of an outdoor unit and an indoor unit, all system components are housed in a single cabinet.
