A split system for heating and cooling is a type of HVAC system that uses two separate units to provide climate control. The first unit is an outdoor unit that houses the compressor, condenser, and evaporator coils. This unit is responsible for taking in outside air, cooling or heating it, and then distributing it throughout the home. The second unit is an indoor unit that houses the air handler, which is responsible for circulating the air throughout the home. This type of system is often used in homes with limited space, as the two units can be installed in different locations. Split systems are also known for their energy efficiency, as they are able to use the same amount of energy to heat or cool a home regardless of the size. Additionally, split systems are easy to maintain, as they have fewer moving parts than other types of HVAC systems.
