Coleman® Furnaces Echelon C Series Echelon™ 9.C Modulating Gas Furnace A cozy family gathering, a relaxing evening, a quiet winter’s morning—your comfort needs change throughout the day. And when a Coleman® furnace is properly matched with a Coleman® air conditioner or air handler, you will enjoy extended system life and maximum efficiency all year around! Here's what makes it work: 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. Coleman® "Split System" Air Conditioners Echelon™ 5T Air Conditioner Coleman® comfort is yours all summer long with Colemans 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.
