My unit has emitted a slight cigarette smoke odor since I got it a year ago. It seems to be getting much worse lately.
At first I assumed it was normal odors of a new unit (as in new car smell) and have gotten used to it to the point that I don't notice it much. But the past few weeks I have noticed that the odor is quite a bit stronger and the whole house is starting to have the odor. If I turn the unit off for a day the odor is gone. Can someone contact the manufacturer and find out if my unit is safe for constant operation in my home?
