Duct Tightening

You want to condition the air where you are but your ducts are probably leaking it before it gets to you. The average house has duct work that is so poorly installed that 25% of the air is escaping through gaps before it ever gets into the living space. Your duct work is passing through your walls and attic where there is a lot of dust and other contaminants. Poorly sealed ducts will allow this air to enter the living space. If you haven't checked your ducts you're probably throwing money away.
