Soooooooo ... after 7 years in this house and around $200k in additions outside, I finally figured I'd clean the vents. They come with the big vacuum and then take a camera to show me what's in the vents. Long story short, my $30 special turned into a $400 deep cleaning.
I think that the most embarrassing part was when they pulled out the filter on the furnace which I was supposed to change a couple months ago and it was totally plugged in cat / dog hair! Whoops --> I told them to change that, too.
