furnace Heating 101


A Residential Furnace keeps your home warm during the cold months, and can be an integral part of a central air conditioning and/or indoor air quality system.

The basic components of a furnace system are:

  • A burner, through which gas (natural or propane) or oil is delivered and burned.
  • A heat exchanger, where the heat produced from the burning gas is transferred 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) to the outside.

    The efficiency of a furnace is rated using a percent of AFUE.

    To help you better understand the cooling process, please look over the material below. This is general information that you will find helpful when working with a dealer.

    Central Air Conditioning
    A Residential Split System Central Air Conditioning system keeps your entire home cool in the warmer months, while it helps lower indoor humidity levels.

    System elements include a compressor, a fan, condenser coil, evaporator coil, and a refrigerant. The unit extracts heat from indoor air and transfers it outside, leaving the cooled indoor air to be re-circulated. The efficiency of central air conditioning systems is shown using SEER ratios (see below).

    Three elements make up a central air conditioning system with electricity as its power source. They are:

  • An outdoor section (the condensing unit).
  • A matching indoor gas or oil furnace with coil, or air handler.
  • Ductwork to transfer the cooled air throughout the home.
