Dehumidifier exhaust

Might not be any use now, being a year later reply. But think your exhaust run from your ac unit to outside is probably too long . You need to add a booster fan in the middle or end of the dryer hose. It’s way better to use straight ducting pipe and replace the plastic coil type or use less as possible. As each coil (bump) in the dryer hose loses cfm. Making the ac not efficient. The heats not getting exhausted out to make it run properly. Though getting the bigger ac was good. Better to have more than not enough. Each 1000w of power = roughly 3,300 btu to cool it. To give a guide.
