Why would your AC be running outside but inside very little air is coming from the vents and it sounds like it does not kick on inside the house?

you need to check to see if the lines or outside unit has an ice build up. unit is probably working too hard, keep it at an even tempature, don't turn down and then turn up constantly. ====Aswer==== Better yet, check to see if the indoor fan motor is running. It could be a bad fan motor, bad capacitor, or bad fan relay.
