York Furnaces


Most home comfort systems have two parts: an outdoor air conditioner or heat pump, and an indoor unit, a furnace. Furnaces heat and circulate warm air in the winter. They also take cool air from the outdoor unit and circulate it through your home in summer. The indoor and outdoor units are designed to work together. When the furnace is properly matched with a heat pump or air conditioner, you enjoy maximum efficiency and extended system life. Furnace heating ability is measured with an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace.

The Affinity™ 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 Affinity™ 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
  • A Head Exchanger, where the heat from the burning gas is distributed to the air distribution system
  • Ductwork to transfer the heated air throughout the home
  • A Flue or Vent Pipe, to exhaust byproducts of combustion (such as water vapor and carbon dioxide) outside

Affinity™ 9.C and 8.C Series high-efficiency gas furnaces are a step up for any home. That’s because York® Affinity™ modulating gas furnaces continuously adjust their heating level by 1% increments to match the degree of comfort you need exactly and efficiently. In fact, they can maintain indoor temperatures to within 1/2 degree of your thermostat’s setpoint. The variable speed, ECM, blower slowly ramps up and down providing quiet and efficient air distribution while reducing overall utility consumption. The Affinity™ 9.C is one of the highest rated gas furnaces in the industry (up to 98% AFUE), which means more efficiency and lower energy costs. Also, the Affinity™ Series 9.C Modulating Gas Furnace recently received high accolades from Consumer Digest—providing further assurance York is a brand you can rely on.
