As far as I know the only thing that HI of LO effects is the speed of the fan. It is like the fan speed in a vehicle, the faster the fan the quicker it should cool as it is moving more air. Coils usually will freeze up for three reasons, either the coil is dirty and it traps moisture which will then freeze, or system is low on refrigerant and that makes it a bit more efficient before it quits. Also there should be a T-stat on the coil that senses the temp there, so it should not freeze up. If your coil freezes up either sensor is out of position, or it is not working right.
