In North Carolina you would see prices that range from $95 to $165 depending on access and other factors that determine how long it would take or risks involved.

Most gas furnaces do not produce enough soot to accumulate on the liner walls. When gas combusts it mainly produces moisture. Sooting can occur when the burner gets fouled and does not combust completely, thus producing soot. I mostly end up removing leaves and other debris (like mortar and stuff that fell in at construction) from the masonry thimble where the B-Vent connects to it. Often that debris can clog or inhibit draft for combustion gases of the furnace.

If your flue ever vented oil prior to gas you should consider making a direct connection from the furnace to the top. This will eliminate future cross contamination and terra cotta flue spalling from said exposure. Also todays high efficient furnaces (above 83% AFUE Rating) should be sleeved with aluminum connection directly if they cannot be vented with PVC out a foundation wall. Hope this answers your question.
