What Is the Proper Position of a Window Type Aircon?

Placement goals

Good window-unit position balances cooling throw, drainage slope, outdoor heat rejection, and noise. A crooked install is a top reason units drip indoors.

Practical rules

• Slight outward tilt so condensate drains outside (follow the manual degrees).
• Outdoor side must have clear airflow — not sealed flush against a wall or aluminum shutter that traps heat.
• Avoid aiming cold air directly at sleeping faces for hours; slight angle across the room often feels better.
• Keep furniture from blocking the indoor grille.
• Upper-floor heat and west windows may need a higher HP — position can’t fix chronic undersizing.

Building constraints

Condos and rentals may restrict window-sash cutting. Confirm landlord rules before buying. Compare window vs split if outdoor space for a split exists.
