Types of Central Air Conditioners
Generally, a central AC system is comprised of a single packaged unit, or is split-system.
Split-system central air systems utilize an outdoor condenser and compressor, while an indoor unit contains the evaporator. On the other hand, a packaged unit contains all 3 of these components, outside or on the roof. Split units are more economical for homes that has a furnace, but not an existing AC unit. Combination package units often include electric heating coils or a furnace; so it acts in place of a furnace in the winter months.
