Last month I had a new ac/heat pump installed..it's a great unit. I had the installers install one return register and Two supply registers in the basement. It's real cool in the basement now.
Outside temp is 80 F and outside Humidity is 82%
I just purchase a Acu-Rite Indoor Humidity Thermometer, it's reading 75% humidity in the basement.
1. Is this very high?
2. if so, how do I get the Humidity down?
3. What should the humidity be in the basement?
