Why the noises in the new furnace?
Called Carrier and talked to a technician. They said it could be transformer or fan motor. They need to be replaced. Will see the company tomorrow.  Keep my fingers crossed.
A technician came. He found out there was a screw between new unit and the return of air duct. He took it out and screwed the two parts together at the base and taped them also. The noise has disappeared since then.
