Have you checked your filters? If you have - and they're clean - then it's possible you have a blocked coil. If that's the case you'll need to clean the coil with a good evaporator cleaner. It could also be a return-air sizing problem. Or a multi-speed motor that needs to be sped up. lol Not a lot of help, I suppose...

Most units a multiple speed motor. If your not having any problems with your heating or cooling then I would say its part of the design. If you are having problems then there might be a function in your t-stat to control motor speed. Otherwise your going to have to read your wiring diagram.
