We recently installed an XL16i system with variable speed ahu and all new ductwork.The condenser has a two stage compressor. We did a manual J. and wired it to manufactuers specs. The humidity levels in the home are between 60 and 70% ! The tstat is in the auto mode. We noticed that there is more water left on the coil after the tstat is satisfied than we would like. Why is there residual water left and is that the problem? The ahu is pitched correctly.
