We recently moved into a new house and noticed a lot of cool air circulating throughout the house even when the heat was on 72 degrees. We just found a register in the laundry room low to the floor with cold air flowing at a high speed. Is this normal? The register is a stand alone. We contacted the builder who told us this is natural but we are questioning this since there is too much cold air circulating. Can someone help us?

No,this is not normal,, cal him back over and over till they get it fixed
