Seems I did a decent job of insulating my shop. Tried to keep the load low. Put in a super efficient split system. Nice and cool. BUT, humid! Seems the variable speed compressors that are so super efficient don't always bring the evaporator cold enough for efficient de-humidification. Cool nights, so not running most of the time. When I set my temp down to 68, coils dropped to 50-ish from 65-ish. Probably more efficient to over cool than to add a dehumidifier. Back is the bad old days, coils ran 40 to 45 so they could really pump it out.
