- Space. Some buildings are built too close to one another that installing it on the ground is near impossible and bothersome to neighbors.
- Appeal. Installing the unit on the roof removes one unattractive element around the structure. Rather than an air conditioning unit, it could be a garden or other landscaping.
- Covers a bigger area. Major advantage of a rooftop unit is its ability to cool multiple rooms. Compared to a window unit or a wall unit, where it’s limited to one area, a rooftop air conditioning is normally attached to ducts that distributes the air to the rooms in the house.
- Freedom from debris and vegetation. Units placed on the ground have a tendency to require more maintenance because of the vegetation and its trimming. Without regular maintenance of the area around the unit, it could potentially reduce the unit’s efficiency
