Coleman® comfort is yours all summer long with our split system air conditioner design. This design has two parts: an indoor unit, such as a furnace or air handler, and an outdoor unit. The outdoor unit works by cooling a refrigerant, which in turn cools air in the indoor unit for circulation through your home. Indoor and outdoor units are designed to work together. When the air conditioner is properly matched with a furnace or air handler, you get maximum efficiency and longer system life.

Here's what makes it work

A "split system" central air conditioner includes a compressor, fan, condenser coil, evaporator coil and refrigerant. The system removes heat from indoor air and transfers it outside, allowing the indoor air to be circulated and cooled (which is measured by SEER, Seasonal Energy Efficiency Ratio). A central air conditioning system uses electricity as its power source.

The basic components of an air conditioning system are:

• A condensing unit (the outdoor section) and the evaporator coil
• A matching indoor air handler or gas (natural or propane) furnace with coil
• Ductwork to transfer the cooled air throughout the home
• Furnace design has advanced in recent years to be far safer and more efficient than older designs. This is the result of improvements in the burner, the ignition, and the blower motor. Furnace heating efficiency is measured by an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace.
  
  The Echelon™ 9.C is one of the highest rated gas furnaces in the industry (up to 98% AFUE). The EnergyGuide label outlines the energy use and efficiency of major home appliances. The Echelon™ 9.C EnergyGuide rating exceeds government standards - insuring exceptional quality and low energy use.
  
  The basic components of a furnace system are:
  • A burner, where gas (natural or propane) or oil is delivered and burned
  • An ignition source, which is typically an electronic hot surface igniter that supersedes the old-style pilot light
  • A heat exchanger, where the heat from the burning gas is transferred to the air distribution system
  • Blower motor, such as the highly efficient electronically commutated motor (ECM) to propel air through the ductwork
  • Filtration and ductwork to circulate clean, warm air throughout the home
  • A flue or vent pipe to exhaust by-products of combustion (such as water vapor and carbon dioxide) outside. High-efficiency furnaces use special, corrosion-resistant vent-pipe materials.
