I was wondering if anyone can offer any information on why this unit seems to be on the low-end of moisture removal though? It seems like the highest efficiency units also seem to be the least capable at moisture removal. Looking at the specs in the picture, the models most capable of moisture removal (pints per day) seem to be the lower efficiency ones. This unit is as low as they go at 51 pints per day. The lower efficiency ones go as high as 81 pints, a big difference.
I'm in S. Florida, and the humidity is pretty brutal! I'd love to run the most efficient unit, but not if it can't also do a good job in lowering the humidity. The humidity is a huge factor in indoor air quality in places like FL.
Thanks for your feedback. This seems like a great deal on a 24 SEER unit!

This is the theoretical driver for the issue. There could be other practical manufacturing reasons too.

Higher SEER2 systems do often get efficiency by using larger coils, lower compressor lift, higher evaporator temperatures, more optimized airflow, inverter/variable-speed operation, and better overall metering. Those things can improve efficiency but yes its a valid worry that those changes may reduce latent removal per hour in lab test conditions because the coil may not be as cold.
But real-world humidity control depends more on runtime, airflow, staging, coil temperature, dehumidification mode, and whether the system is oversized. For Florida where I live and work, the big issue is that a lower-efficiency SEER2 17 system can remove more moisture while it is running, especially if it has a colder coil. But if it satisfies temperature quickly and shuts off which most would, it may not remove as much total moisture over the day. A SEER2 22 variable-speed or communicating system may show lower moisture removal on paper, but in real life it can often do better because it runs longer at low capacity, keeps air moving across a cold coil longer, and some even have a dehumidification setting that slows the blower down to increase the effect.
