You can lower the blower speed however if the air flow is too slow the coil temperature will be too low causing it to freeze.

Have you tried diverting the air flow so it does not hit you directly? Air coming right at you creates a wind chill effect.

I did that it doesn't matter I still too cold 76 77 deg iI can handle buy wen input in 75 degrees at nihhg tgenthen it gers freezing as iI fall asleep my temperature drops have no choice to lower blower spped enless it has to much freon

Have tried setting the thermostat to 78 when you go to bed?

Y

So I take it that it's the draft cause by the airflow from the vents that's bothering you, rather than the actual temperature?

No

What is your location?

Does your thermostat have a dehumidify feature?

(what is it set at? humidity)

Set thermostat to 79. Still to cold? set to 80.

If the thermostat has a dehumidify feature raise it higher.
