There are four different types of furnaces that include oil, electric, duel fuel and gas. The gas furnaces that are the most efficient types are those recognized by EnergyStar®. With the help of the outside’s fresh air, as much as 98% fuel efficiency is achieved in modern furnaces. Today, we at Air Supply Heating & Air Conditioning would like to elaborate on the basic parts of a gas furnace.

Basic Furnace Components

There can be a single-stage, two-stage, or modulating furnace, depending on the type of gas furnace. When it comes to the mechanisms and parts that combine to deliver clean, warm air in the home’s rooms, all furnaces share similar components. To help better understand the mechanics of how the unit works, below are the basics components of a gas furnace.
1) Thermostat: The temperature inside your house is designed by the thermostat and will signal the ignitor when to turn on.
2) Supply Plenum: Distributing heated air throughout your home, the supply is a duct that is attached to the furnace.
3) Return Ducts: Cooled air from home is retrieved by the return ducts which is then air is returned to be reheated via the furnace.
4) Flue: To channel the unwanted exhaust that contains carbon monoxide outside, the flue channels are responsible.
5) Hot Surface Ignitor: Following the thermostat signaling to turn on, initially, an electrical current is sent to the ignitor in order to light the burner.
6) Heat Exchanger: After the heat from the gasses is absorbed into the walls as the combustion gasses enters the heat exchanger and the combustion gasses are cooled and vented into a pipe.
7) Burners: Before the heat passes to the heat exchanger, the fuel is sent to the burners, they are ignited by the hot surface ignitor to produce a consistent, controllable flame.
8) Blower Motor: The air is pushed past the heat exchanger into the supply plenum by the air blower motor for air distribution throughout your home.
9) Air Filter: The air filter catches debris, dust, and particles in the air prior to the air entering the blower motor.

Furnace Maintenance Checklist

In order to preserve its longevity, performance, and overall efficiency, no matter how efficient the furnace is, however, the furnace will need to be maintained by owners and professionals.
1) For at least once every 90 days, replace the furnace filter.
2) About every month, periodically check the furnace flame color. An indication of a serious problem that requires a professional is the furnace flame is orange, red, or green, if the furnace is healthy, the flame will blue with perhaps a small yellow.
3) Optimally performed at the end of summer, early fall, schedule a professional tune-up at least once a year. Professionals will inspect the ventilation system, clean your pilot light, and test your heat exchanger for cracks, clean, and more.
