This most likely means that you have a clogged filter which is reducing air flow. When the filter is partly removed, air is allowed to flow freely. Try cleaning or changing the filter. Another possibility is a problem with your air ducts, either being too small or somehow restricted.
If you change the filter and still have the same problem, you should have your furnace checked out by an HVAC professional. If you'd like to have a contractor take a look at your furnace, we can help you find one, here.
