What are the disadvantages to oversizing a dehumidifier? Is it even meaningful to say that a dehumidifier is oversized? With A/C, I want longer run times because they lead to better dehumidification. But if a dehumidifier quickly brings the RH down to where it needs to be, what is the problem with that?
One clear disadvantage is that larger dehumidifier cost more up front. What isn't so clear to me is whether an oversized unit costs more to run.
