Cooling / Gas Furnace Split System
With conventional non-self contained split gas-electric systems the fan system which moves air through the ducts, the cooling coil module and furnace module are located indoors. Furnace sections and coils are available which discharge air horizontally or vertically. Also, the furnace section may be installed without other split system components to provide heating only operation. Furnaces may also be converted from natural gas to LP gas configurations with an accessory kit. The compressor and condenser (outdoor) fan are located in an outdoor weatherized cabinet called a condensing unit. Split furnace systems offer the advantage of greater variety in efficiencies and capacities which can be created by mixing and matching indoor / outdoor sections. Split systems are also a good option where there is not room to physically locate a larger packaged system outdoors. Air-cooled split furnace systems range in sizes from 1½ - 10 nominal tons cooling capacity (in larger capacities a "twinning" kit may be required).
