You would do well to install a 2 stage unit there.
But your unit is over-sized or it would not short cycle.
If you installed a dehumidistat to bring the strip heat on (reheat) then the compressor would run longer and bring the humidity down. High humidity is not good for electronic stuff like computers.
A dehumidistat would be a cheap fix up front, but expensive to operate.
Doing what beenthere said would be the best long range solution.
