    house is about 2000 sqft, basement and 2 floors, basement isn't heating, my question is do i need to have a return (on a second floor) high up on the wall for better air circulation or ones by the floor will do. thanks

    Leave it alone if your comfortable.I'm sure you have other things to worry about.Let the system do it's job,and until a problem ;not sufficient heat or cooling occurs,don't sweat it.

    I'm not quite sure what's going on with this post.
    You have a new system installed recently and the basement is not heating. You were asked if you are having a problem with your system and you posted a reply of no.
    If your basement is not heating, I am assuming that it will not meet the temperature set point you have chosen....is that correct?
    If it is meeting it's temperature setting requirements, you can assume that the design is adequate and you need not worry about it as suggested by Jeff.

    heat rises and your returns on the second floor should be near the cieling in each room and the hall if this can be done. on the first floor returns should be near the floor to pull back the cold air in winter
    this is ideal but not always applyabe

    "basement isn't heating"
    Do you mean basement is not heated ?
    Any way yes you need a high return and ceiling supplys, for a preimum system use "b" boxes in the cieling with curved blade diffusers and zone your system with over sized ducting to the zones so you dont have to bypass much airflow.

    Common misconception but the location,high or low ,for returns has very,very little effect on operation or comfort.

    You do need a return on each floor and a return "path" from all rooms .back to the main return ,as a minimum .

    Hmm Return Air placement is important

    Dennis here is a reprint of one of my posts that may help you.

    Air Flow
    Chip where are the returns? How many and in what rooms?

    It is very difficult to heat or cool a room that does not have a return in it. Here returns are in all rooms except Kitchens, Bathrooms and Laundry Rooms. In my home, I have High and Low Louvered Returns. That way for the Winter, on Labor Day, I close the top and open the bottom. Then in the Spring on Memorial Day, I open the top and close the bottom. I can also adjust the flow in the rooms by how much each return is opened. For example on the East side of the home, the returns are reduced for the Summer and on the West side, wide open. This way I do not have to adjust the supply side. I call it Xs Return Air Balancing!

    P.S. Booster Fans DO NOT increase Flow!
