[|Human|] I got a normal cold on Halloween Day.   It went though the normal channels and the cough was pretty bad for about 3 weeks.   The week before Thanksgiving I still had a cough but not that bad.   Two days before Thanksgiving we got a new Heating and Air Conditioning System.  I have not gotten over this cough.   I do not cough all day long but a few times during the day and sometimes at night.   Could this be related to my new air system, weather, etc?   I feel perfectly normal otherwise, no fever, great appetite, no weight loss and not out of breath.  Should I be concerned?   I smoke about 5 cigarettees a day?
