When I change the setting from A/C to FAN does it draw the air in from the outside or only move around the air already inside my condo? If not, is there any way to draw in the air in from the outside rather than just pushing around the air inside? I live on the first floor and have no windows aside from the four sliding glass doors. This place is notorious for thousand leggers and I can't stand those quick moving critters. I notice whenever I open up the sliders to get fresh air I will start to see those little buggers inside the house. Yuk!! They just totally creep me out. I have sprayed bug spray around the doors to inhibit their entrance, to no avail. I'm also a smoker so it's really important that I get some FRESH air inside my house. Any advice would be greatly appreciated! Thanks.

Just moves it around

Call a local HVAC contractor and see if they can add a outside air intake to your system. It will cost you more $$$ on your utility bill since you will have to heat and cool the air you bring in from outside.

I`m sorry,and I know its none of my business, but,if you stopped the smoking you would
1. be healthier/feel better
2. not have to air out the stink in your house
3. have more money in pocket
4.by not having to let the little buggers into your house,you would have more peace of mind.
(again I know its none of my business,but I`m an ex-smoker,after 15 years I am still paying dearly for my mistakes from when I was younger) and will for what's left of my life

Seems like a contradiction... a smoker wanting fresh air... apparently you really don't want it.
