My Honeywell Vision thermostat (retail version from Lowe's) won't let me adjust temp swing or cycles per hour. Will I damage compressor by lowering fan speed to medium to increase run time/humidity removal. Hopefully that would bring up split temp 20 degrees or more. I have noticed that my Carrier compressor is very loud when running. It has been this way since I bought the home new two years ago. Are they loud by nature or could there be a problem there?
