How can I raise the output temperature of my air conditioner for better comfort?
There isn't too much refrigerant in the unit. It doesn't work that way. Check your thermostat setting and verify its accuracy with another cheap thermometer. Readjust the directional settings of your AC registers so they're not blowing directly on you. Restrict their flow by closing them a bit, they are fully adjustable. Be thankful it's cold; most people complain their AC doesn't get cold enough.
