You light a fire expecting warmth and ambiance, but instead smoke billows back into your living room. This frustrating problem happens more often than you'd think, and it's usually not about your fireplace being broken. Cold air sitting in your chimney creates a downward draft that pushes smoke into your home instead of letting it escape.
