How an AMANA Central Gas Furnace Works

Simply put, a central gas heating system creates a cycle of increasing the temperature of cooler air.

Here is the simple version:

  1. Burning propane or natural gas generates heat in the furnace’s burner.
  2. The heat produced passes through a heat exchanger, making it hot.
  3. Air from the home’s ductwork is blown over the heat exchanger, warming the air.
  4. The furnace’s blower then forces the heated air into the supply ductwork, distributing it throughout the home.

Parts of a Central Gas Furnace

Of course, the central heating system components must work together to keep you comfortable.

  • Temperature Control – The temperature control, which is regulated by the furnace control board, turns on the ignition switch and starts the heating process when the thermostat or control system calls for heat.
  • Draft Induced Fan – The draft induced fan draws air into the burner assembly. The air also allows the burners to warm the heat exchanger then is exhausted outside of the home.
  • Gas Burners – When the thermostat or control system calls for heat, the gas burners valves are open to deliver gas and burn fuel.
  • Ignition switch – Gas flows over the igniter to establish a flame. This flame is drawn through the burners and used to heat the heat exchanger.
  • Heat exchanger – The part of a gas furnace that adds heat to the indoor air. The gas combusts inside the heat exchanger, creating heat that is used to heat the passing air. The design of the heat exchanger can add energy efficient operation of a gas furnace.
  • Draft-Induced Fan – Draws air into the burner assembly. The air allows the burners to warm the heat exchanger.
  • Blower Fan – Uses the return venting to blow air over the hot heat exchanger. The conditioned air is then sent throughout your home via ductwork. Some furnace models offer a blower fan that can run at multiple speeds to improve efficiency.
  • Flue – A flue or chimney acts as an exhaust for gaseous by-products of combustion used to create heat.

Gas Furnace Categories

Gas furnaces come in a variety of shapes to fit your space. However, they can also be categorized by one of the following:

  • Non-condensing furnaces – vent exhaust gases out of the home, typically through the roof.
  • Condensing furnaces – uses a second heat exchanger to heat the air from condensed exhaust gases to reach higher efficiencies.
  • A modulating gas furnace – continuously regulates the amount of fuel burned to maintain the set temperature of your thermostat. This modulating component can minimize indoor temperature fluctuations.

 

How an AMANA Central Air Conditioner Works

The Refrigeration Cycle

  1. Using electricity as its power source, the refrigerant flows through a closed system of refrigeration lines between the indoor unit and the outside unit.
  2. Warm air from the inside of your house is pulled into ductwork by a motorized fan.
  3. The refrigerant is pumped from the exterior compressor coil to the interior evaporator coil, where it absorbs the heat from the inside air.
  4. This cooled air is then pushed through connecting ducts to vents throughout the home, lowering the interior temperature.
  5. The refrigeration cycle continues again, providing a consistent method to keep you cool.

Parts of a Central AC System

A typical central air conditioning system is a two-part or split system that includes:

  • The outdoor unit – Contains the condenser coil, compressor, electrical components, and a fan.
  • Evaporator coil – Which is usually installed on top of the gas furnace inside the home.
  • Refrigerant – The substance in the refrigeration lines that transfers heat into or out of an interior space. It is circulated through the indoor and outdoor unit.
  • Ductwork – A network of metal, fiberboard or flexible material that serves as the air tunnels to deliver conditioned air to the various spaces inside your home.
  • A thermostat or control system – A wall mounted device that monitors and controls the output of your conditioned air.

Benefits

  • Indoor comfort during warm weather – Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air – As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to rooms.
  • Quieter operation – Because the compressor-bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.
