I just had a new system installed in December, we have a 6500 sqf home, I have two units one is a 5 ton the other a 3 ton for the upstairs and we have 3 400 foot wells. It's closed loop. The units cool great, they are not doing much with the humidity though. I'll have the temp set to 70, the rh will be 59% and I have the rh set to 45%, upstairs is worse, I have it set to 45% there but it reads on the thermostat being 64%. I have a dehumidifier running and the rh reader on that said 81% so now I don't know what to think. I had the fan set to on for circulation but I just switched it to auto to see if that makes a difference, I have had the installers out several times I feel like I'm getting the run around. Is there a problem with these units for dehumidification?
