[Greenbuilding] Basement dehumidifier vs window AC with dehumidifier function

[Benjamin Pratt]

I run a dehumidifier in the basement all summer. However, it does get
uncomfortably warm down there. I have an office that I use about one a
week for several hours, and exercise equipment that use 3 times a week
for an hour at a time.
I was thinking about putting in a widow AC (potentially with a
dehumidify function). Should i use this only when i need it, or
replace the dehumidifier. Which would be more efficient? If I am only
going to use it when i need it, i can will put in an AC that I already
have. IF not, I will buy one with an AC dehumidify function. IT would
obviously be preferable to keep the basement at a comfortable
temperature.
