A split unit heater is a type of heating system that utilizes two separate units to heat a space. The first unit is an outdoor condenser that contains the compressor and condenser coils. This unit is responsible for cooling the air and then transferring the heat to the indoor unit. The indoor unit is typically a blower fan that circulates the heated air throughout the space. This type of system is ideal for homes and businesses that need to heat a large area, as it is more efficient than a traditional furnace. Additionally, split unit heaters are often quieter than traditional furnaces, making them a great choice for areas where noise is a concern. Split unit heaters are also more energy efficient than traditional furnaces, as they are able to heat a space more quickly and efficiently.
