There’s quite a laundry list of things you need to go through when it comes to selecting a new furnace. It can be pretty easy to lose certain details while working your way down the list, but there are a few things you absolutely should not skip. Size is one of those things. A furnace that is not properly sized can cause a whole swath of issues for homeowners, and can even lead to a need for early replacement.
(Keep in mind that when we refer to the size of the furnace, we’re primarily talking about the level of output the system creates.)
