Heating and cooling split systems are the most common types of HVAC systems used in residential buildings.
They consist of two separate components — one for heating and one for cooling
use a traditional thermostat to control the temperature for the entire structure.
In most buildings with split systems, the heating unit is located in a basement, utility closet or other indoor storage space. The heater is gas-powered and uses an evaporator or fan to push heat through a building’s ductwork. On the other hand, the cooling system is located outside and connects to a building’s ductwork through a series of tubing. It uses compressors, coils and refrigerant to create cool air, and a fan directs hot air out and away from the building.
