Furnace makes a awful noise when I try to run central air. It seems to be the blower, as it seems to be making the most noise when it's turning[ I pulled the lower front cover to verify where the noise is coming from.] the model is a HEIL MODEL#nugk075dg01.
Can I replace the blower?
Thanks ,

Is the blower cage supported by a bearing? Check that as it may be allowing the cage To hit the housing. Some direct coupled units have had issues with the motor mounts cracking.
