Even when the knob is off and I switch it to high it blows air out.

Did you put the Freon in...LOL.....
OK, so what are the pressures? no gauges? Take the low side pressure switch and bypass it and the compressor should cut on, if not you have to see why. of the compressor cuts on then you will probably be low on Freon.
