The definition of a split HVAC system is a type of heating, ventilation, and air conditioning (HVAC) system that uses two separate units. The first unit is located outside the home and is responsible for cooling and heating the air. The second unit is located inside the home and is responsible for distributing the air throughout the house. The two units are connected by a network of ducts, which allows the air to be distributed evenly throughout the home. Split HVACHVAC systems are becoming increasingly popular due to their energy efficiency and cost-effectiveness. They are also easy to install and maintain, making them an ideal choice for many homeowners. Split HVACHVAC systems are designed to provide efficient and effective climate control for the entire home, allowing for maximum comfort and energy savings.
