The best location for your air conditioner at home – indoors and outdoors

Deciding where to place your air conditioner — both indoors and outdoors — has a major impact on comfort and energy efficiency. Correct placement allows cool or warm air to circulate properly, helping your system reach the desired temperature faster while reducing energy use. The best location depends on factors such as room size, airflow, sunlight exposure and home layout. In this guide, you’ll learn the best positions for air conditioners in living rooms, bedrooms and outdoor spaces to maximise performance and comfort.

Air conditioner systems and how they affect placement

Placement depends largely on the type of air conditioning system installed. A single-split system cools one room, while a multi-split system connects several indoor units to one outdoor unit — which directly influences where indoor units should be positioned.

Single-split system – one indoor AC unit

A single-split 'pair' system consists of one outdoor unit connected to one indoor unit. This setup is ideal for smaller homes or apartments.
If you’re wondering about the best position for an air-to-air heat pump in a living room, it is usually best placed high on a wall, where air can circulate freely across the room.

For bedrooms, placement is also important for comfort. The best position for an AC in a bedroom is often above the bed but not blowing directly onto it, ensuring even cooling or heating while supporting a restful night's sleep.

Ultimately, if you install only one unit, choose the largest or most frequently used room to get the best return on your investment.

While high-wall units suit many spaces, the Daikin Perfera floor-standing unit offers a great alternative for rooms with limited or angled wall space. Its sleek, low-level design is discreet, easy to access, and simple to maintain. Its ground-level placement makes it easier for elderly users or those with mobility issues to access the controls and perform routine maintenance like cleaning the filters.

Multi-split system – up to five indoor AC units

For larger homes or multiple rooms, a multi-split air conditioning system allows up to five indoor units connected to one outdoor unit. This setup lets you control temperatures in each room individually while saving space on exterior walls.

When planning split AC placement in different rooms, prioritise the areas where people spend the most time - living areas, bedrooms, home offices.

A professional installer will also help ensure the system meets local regulations for outdoor placement, drainage and electrical connections.

Five factors that affect indoor air conditioner placement

Positioning your air-to-air heat pump unit correctly maximises cooling and heating efficiency while helping extend the lifespan of the system.

Consider the following factors before installation:

1. Easy access for filter cleaning and maintenance
2. Good airflow — avoid curtains, furniture or obstacles blocking vents
3. Natural airflow direction — avoid placing units directly opposite doors or windows
4. Distance from heat sources — keep away from appliances and electronics
5. Avoid direct sunlight — heat exposure makes the unit work harder

If you are considering the best position for portable air conditioner models, the same principles apply. Ensure unobstructed airflow and access to a nearby window for ventilation.

Where to install your outdoor air conditioner unit

The outdoor unit plays an equally important role in system performance. Its location affects noise levels, efficiency and maintenance accessibility.

Four tips for locating your outdoor AC unit:

1. Install the unit in a well-ventilated and shaded location
2. Keep the surrounding area clear of bushes, debris and obstacles
3. Ensure easy access for maintenance and servicing

Avoid constant direct sunlight, which can reduce efficiency

Seek professional guidance for air conditioner placement

These are some of the key factors to consider when determining the best placement for your air-to-air heat pump. However, there is rarely a single solution that works for every home. A professional installer can assess your home layout, construction and ventilation needs to determine the most suitable placement for both indoor and outdoor units. Their expertise ensures optimal performance, safety and compliance with local installation regulations.

Choosing the best air conditioner placement for comfort and efficiency

Choosing the right location for your air conditioner is essential for comfort, efficiency and long-term performance. Proper placement improves airflow, reduces energy consumption and helps your system reach the desired temperature faster. By considering factors such as room layout, airflow direction and outdoor conditions, you can ensure your air-to-air heat pump works efficiently year-round. A professional installer can help determine the best solution based on your home and installation requirements.
