Hello, pls don't flame me on this post! Recently (on & off), we've
been smelling some smoke odors in our 2-story house. There are NO
smokers in our house. There is no odor in the mornings nor
afternoons, only in the evening/nights.

I scanned some posts here and it appears that smoke odors may be
related to the A/C components, correct?

One thing I have yet to determine is if a walking neighbor (who is a
smoker) could smoke around the perimeter and the odors would
permeate our house. I don't know if this is posible with the A/C
off.

Thanks for any info!

It's certainly possible. I can usually smell when a car in front of
me has a smoker in it.

Either my nose is getting better or cigarettes are actually smelling
worse over time.

I'm the same way. I ran past a smoker sitting on a park bench and
could smell her smoke and perfume when I was down wind, 200 yards from
her. Smoker's don't realize how stinky they are. As for OP, nose
should be able to differentiate between cigarette smoke, wood smoke and
electrical component. I sometimes get some transient fireplace odor in
my house due to furnace draw.
