since you said warm air is coming out we know the inside unit is running….is the outside unit running…if yes….is compressor and fan running or just fan…there is only a few reasons for an ac to blow warm air…1 compressor not running A bad capacitor B brunt wires where they connect to compressor….2 condensing unit not running..A bad contactor B no power C high or low freon pressure switch kicked out, low pressure is automatic, high presure will have a manual reset buttton where the linesets come out of condensing unit…3 could possibly be bad thermostat or broke thermostat wires at condenser , an easy check is to touch the yellow wire to the red wire and see if it starts ….4 if you have power but unit is not running and you can hear contactor buzzing…then bad capacitor
