Can you install your own forced air furnace?

It is possible to install a forced-air furnace without the aid of a professional, according to home maintenance website DoItYourself. However, there are many steps in installing a furnace that can pose safety risks during the installation or in the future, making it a complex task.

Forced-air furnaces are somewhat easier to install than past furnace designs, in large part since most use direct-vent technology that allows exhaust gases to be expelled through a plastic pipe rather than requiring a chimney for exhaust. However, it is vital that anyone installing a furnace take care to properly route gas lines and ducts to avoid potential leaks of toxic or flammable gases.
