I have a Coleman Model 7665 furnace in a 1982 mobile home updated/remodeled in 2003... I know nothing about this furnace and would like to know if it is electric or gas? Also, where can I get parts when needed and I'm located in Griffin, Ga.

I`m sorry, but if you can`t figure out if your furnace is gas or electric,you don`t need any parts you couldn`t figure out where to put them

Post a pic of the furnace with the covers off. We will let you know if its gas or electric.

With a furnace of that era, I would suggest getting in a hvac tech to look the unit over and explain to you the way it works. Don't expect a training course in heaters, just ask them the basic operation of the unit. And honestly, start thinking about putting a little away to save up for a newer, more efficient furnace. At least if you have a new furnace installed, you will know that parts are available for it from the person that installed it. And a warranty to boot.
