I am having humidity problems with Carrier 5 ton system. House is 2 years old and 2400 sq ft in size (2 story). My system seems to be short cycling anywhere from 8-10 minutes on time and 8-10 minutes off time (during the heat of the day, which is low 90's here in South Texas). The short cycling gets worse at night (3-5 minutes on 10-15 minutes off). The RH inside the house stays at 60-65% with thermostat set at 76-77 (Honeywell Vision 8320-retail version). I was wondering if I could lower blower speed to lower setting without harming system? I have looked at schematics on blower and it says nothing about CFM only that black wire is "high", blue wire is "med/lo", and red wire is "low". From reading posts I know you are looking for 350-400 CFM for max humidity removal. Does anyone know what the CFM is for each speed on my particular system?
