Split Systems: The most popular kind of central air conditioning system, a split-system A/C consists of two units. Its indoor evaporator coil strips the interior air of heat and moisture and circulates the cooled air via ductwork throughout the house. The outdoor condensing coil releases the heat into the air with the help of a compressor. The heat energy is carried by refrigerant between inside and outside. For homes with existing duct systems, split systems are usually the best option.
Heat Pumps: These air conditioner systems providing both cooling and heating. Like the split system, heat pumps consist of two units – one inside and one outside. During summer, the pump strips heat from the indoor air and releases it outside. During the winter months, it extracts heat from the outdoor air and pumps it inside the house. As with the split-system A/C, the heat exchange is accomplished with refrigerant that releases and extracts heat as it transitions between a gas and a liquid. Heat pumps are ideal for homes in with mild winters, though they can struggle to heat a home during prolonged cold weather. That's why they commonly come with emergency heating elements – either electric or gas – that kick on when the weather drops much below freezing.
Packaged Central A/C Units: In these air conditioner systems, a condenser, compressor and evaporator are contained in one unit that's installed either on the roof or on a concrete slab adjacent to the home. It’s attached to ducts that run from the roof or an exterior wall, through which hot air is removed from inside and replenished with cool air. With additional heating coils or a natural gas furnace, these systems can be used for both air conditioning and heating.
Ductless Mini-Split Systems: These are a great option for homes without a built-in duct network. This system involves both an outdoor compressor and condenser and one or more indoor air handlers. The indoor components are only capable of cooling the room or area in which they are installed. Refrigerant is circulated between indoor and outdoor components via tubing.
