The single hose units are not very effective as all the hot air they vent outside is replaced in the cooled space by air leaked from outside into the space. IE if its 100 deg outside, you are using cooled interior air to cool the condenser and exhausting it outside. This air is replaced by 100deg outside air. The dual hose units use outside air to cool the condenser just like your roof unit does. Single hose units are VERY inefficient and approach 0% as the temp differential from inside to outside reaches 20 degrees or more.
