A split furnace system is a type of heating system that utilizes two separate components: an indoor unit and an outdoor unit. The indoor unit is typically a furnace or air handler, while the outdoor unit is typically a condensing unit. The two components are connected by a series of ducts, which carry the heated air from the furnace to the condensing unit. The condensing unit then releases the heated air into the home. Split furnace systems are a great option for homeowners who want to maximize their energy efficiency and reduce their energy costs. They are also ideal for those who want to control the temperature in different areas of their home. With a split furnace system, you can set different temperatures in different rooms, allowing you to customize the temperature of your home. Additionally, split furnace systems are more efficient than traditional heating systems, as they are able to better utilize the heat generated by the furnace.
