Gas Forced Hot Air seems to be blowing extremely hot air

Gas forced hot air. The floor registers are hot to the touch after 6 minutes heat running, if left hand on register would burn quickly. Don't remember it being this hot before.

Check the return air -- ensure the filter is clean and the flow through the return grille(s) is good. A furnace should have high temperature cut-out and possibly even low airflow safeties, but I suppose these could be absent, failed, or bypassed.
