A split HVAC unit is a type of heating, ventilation, and air conditioning (HVAC) system that consists of two separate components: an outdoor unit and an indoor unit. The outdoor unit contains the compressor, condenser, and expansion valve, while the indoor unit contains the evaporator and fan. The two units are connected by refrigerant lines, which allow the system to transfer heat between the two units. Split HVACHVAC units are a popular choice for homes and businesses because they are more efficient than traditional HVAC systems, as they allow for more precise temperature control and zoning. Additionally, they are more aesthetically pleasing than traditional HVAC systems, as the outdoor unit can be placed away from the building, out of sight. Split HVACHVAC units are also more reliable than traditional HVAC systems, as they are less prone to breakdowns due to their two-part design.
