1) Open the windows as much as possible, this helped air the house out, but I've also heard the UV rays will help breakdown the oils and air pollutants.
2) Removed all carpet in the home.
3) Cleaned all the ducting with a mop and soap and water, reached as far back into the ducting as I could.
4) Replaced the return air filters, placed charcoal on top of the filters.
5) Left the central air fan on to circulate air through the filters, so it passes by the charcoal.
6) Washed all walls and ceilings with TSP/water solution (nicotine streamed down the walls), rinsed afterwards.
7) Primered all walls and ceilings with Zinnsser's BIN primer, this stuff is caustic smelling, but works like magic.
8) Painted everything with finish coats.
9) Mopped floors, installed carpet.
Now you can not even tell anyone has ever smoked in this house!
It was a LOT of work, and knowing what I know now, I would knock off about 10-15% off a houses price for the labor and materials to do the job.
