Forced air furnaces are commonly used in North America because it has a unique method of heating which is best suited for the houses in this continent.
This type of furnace can produce heat in every room in the house with just one central furnace. With this furnace at hand, you don’t need to purchase an individual furnace for every room.
It can deliver heated air to every room without a doubt because of its ability to create air-conditioned air through double up.
To have a long lasting unit, you must be acquainted with its parts and components so you will know each of its functions and how to repair it if it got damaged.
The basic parts of forced air furnaces are:
a) Air handler which acts as a blower;
b) Burners that are gas-fueled or powered by electric-resistant heating elements, used for heating air;
c) 2 ductworks, one transports room air towards the heater and the second ductwork sends heated air to the rooms;
d) And thermostats which are used for turning on and off the unit.
The other components are the filters that clean the air, registers that manage the control of the flow of the heated air, and the flue where combustion gases pass through and finally emitted outside.
When buying a furnace that uses forced air, you must also consider its energy efficiency. There are already new models that give off heated air while trying to save energy.
There is also a model that can work even if the heating supply is from a steady coal or wood fire. If you want to help the environment then buy forced air furnaces, which have the highest annual fuel utilization efficiency (UFAE).
The unit should also have the ENERGY STAR label to assure you of a high efficiency furnace.
