Try getting rid of dampness with a dehumidifier. Most HVAC units would not "pull" air from your basement, they recirculate air already in the house. If your basement is unfinished and unheated, there is no reason that your air handler should be pulling in any of that air, unless there are leaks in the basement duct work on the intake side of your air handler.So you could check for leaks there.

Any part of the house that is heated/cooled is inevitably going to have it's air mixed with the air from the rest of the house, because that is how air handlers work. If your HVAC heats/cools your basement, it would probably have a return air duct in the basement, and this is normal and necessary.It is hard to diagnose and cure the problem without knowing more, but here is a suggestion: "musty" may come from the basement being too damp. If that sounds like your basement, you might consider putting a portable dehumidifier down there and see if it eliminates the smell.

I have used these and they are not too expensive, and they remove a huge amount of water from the air. If that works and solves your problem, you can have a dehumidifier with a permanent drain installed in your air handler. Last of all, check if you have any kind of mold or mildew anywhere in your basement.

These also create a smell. If so, this would be something probably connected with moisture and humidity. Dehumidify, and try to eradicate any visible mold or mildew.

Check the drian hole. Chances are the smell is caused by a clogged drain hole. If you can locate the hole in the unit use a bent wire hanger to clear away any dirt or debris.

Next check the bottom of the unit to see if water is pooling underneath. Try and mop up the escess water.

When my husband and I moved into an older house it had a really bad musty odor. We could not figure out what was causing the odor. We tried doing repairs, but nothing worked.

The neighbor across the street (also with an older house) told me about an odor eliminator that she uses. It's called Room Shocker and it worked great! It is environmentally friendly too!
