Blower fan noises

Hello all,

When I turn on my heater/ac fan it makes a lot of noise. If I turn it up for a little while it goes away. I was just wondering if anyone else had this problem and what can be done to fix it.

Thanks,

LTK

probably a dead mouse. when you first turn it on, the mouse keeps falling to the bottom. when you turn up the speed, the mouse just keeps flying in circles with the fan and that's why the noise goes away.



LOL true story.

could also be leafs. the only way to really tell why a heater fan is making noise, is to pull it and see what bouncing around in there.
