As the Dubai summer approaches and temperatures soar, having an effective air conditioning (AC) setup is no longer a luxury – it’s essential. But did you know that how your room is arranged around your AC unit can dramatically impact how well it cools, how much energy it consumes, and how comfortable your space feels?

In this guide, we’ll show you how to optimise your room layout depending on where your AC unit is installed – whether you’re dealing with a wall-mounted split unit, ducted ceiling system, or portable AC – and help you stay cool, cost-efficient, and prepared for summer.

The best AC unit placement (and why it matters)

1. Install on the longer wall (if possible)

In rectangular rooms, wall-mounted AC units should ideally be installed on the longer side of the wall. This allows better airflow across the full width of the room and helps maintain an even temperature.

2. Avoid direct sunlight

If your AC unit is exposed to direct sunlight, especially during Dubai’s peak afternoon heat, it will have to work harder to cool the space. This leads to higher energy bills and a shorter lifespan. Install units in shaded areas where possible or use thermal blinds.

3. Allow for airflow

Whether it’s a wall unit or a ceiling cassette, make sure there is adequate clearance around the AC. Leave at least 30 cm (1 foot) on each side, and never block the vents with furniture, curtains, or decorative panels.

How to arrange your room based on AC location

The placement of your furniture should complement the AC’s airflow, not obstruct it.

1. Keep air vents unblocked

Avoid placing large pieces of furniture – like beds, wardrobes or sofas – directly in front of the AC unit. This blocks airflow and results in poor cooling across the room.

2. Create a clear cooling path

Make sure that cool air can flow freely across the room. For example, if the unit is above the door or window, avoid positioning your bed or desk directly in the line of airflow.

3. Use reflective and light-coloured surfaces

Incorporating light-coloured or reflective materials in your décor – such as white curtains or pale-toned rugs – helps reduce heat absorption and improves the room’s cooling effect.

Extra tips to stay cool in summer

1. Set your thermostat to 24°C

As recommended by DEWA, keeping your AC at 24 degrees Celsius strikes the right balance between comfort and energy efficiency.

2. Use ceiling fans together with AC

Ceiling fans can help circulate cold air more efficiently. Make sure they’re spinning anticlockwise in summer to push the cool air down.

3. Block heat with curtains or smart blinds

Install thermal curtains or smart blinds to block direct sunlight from heating the room – especially in spaces with south- or west-facing windows.

Checklist: Get your AC summer-ready

Before the hottest months hit, do a quick maintenance check:

  • Clean or replace filters – Dirty filters reduce efficiency and airflow.
  • Clear debris from outdoor units – Ensure at least 60 cm (2 feet) of clearance.
  • Test the thermostat – Set it a few degrees lower than room temperature to check if it’s responding accurately.
  • Book professional servicing – A yearly check-up ensures your system is ready for continuous use.

Example room setups based on AC placement

Here are a few diagrams to illustrate how to optimise your room layout based on where your AC unit is located.

1. Living room – AC on longer wall

  • Unit placed centrally on the longer wall
  • Sofa positioned to face the unit without blocking airflow
  • Curtains to shield against afternoon sun

2. Bedroom – AC above bed headboard

  • AC above the bed but angled so cold air flows over, not directly on, the sleeper
  • Bed centrally positioned with clearance around sides
  • Minimal items between the AC and the foot of the bed

3. Home office – AC on side wall

  • Desk placed adjacent to airflow path, not directly beneath
  • Shelving units placed away from AC vents
  • Use of bright walls and reflective surfaces for better cooling

Final thoughts

Whether you’re in a one-bed flat in JVC or a spacious villa in Arabian Ranches, how you set up your room can make or break your cooling experience during Dubai’s long summer. Small adjustments in AC placement, furniture positioning, and material choices can lead to noticeable improvements in comfort and energy efficiency.
