Hello all -

I am new to home ownership and have a room I would like to convert into a man room, complete with a ventilation system that would allow me to smoke cigars inside during the colder months. I am clueless as to how much such a ventilation project would cost to have professionally done. I am thinking I would need an exhaust fan and duct work and a mechanism to replace the removed air with fresh air. I would also need a way to heat the incoming fresh air, again for the winter months. If anyone knows or thinks he/she knows how much such a project would cost, or any other ideas I should consider, I would appreciate the insight.
