The number one reason we get the question of, “Can I install a furnace in my attic” is because the customers asking want to save space. And we get it! It is possible to do this, however, there are a number of factors to consider.
Usually, a furnace is going to be installed in the basement, or garage area if a basement isn’t available. If there’s no garage or too little garage space, that severely limits your options, taking up too much space that would otherwise be usable.
