Living Room Air Conditioner Guide
Your living room is one of the most used spaces in the home. This guide explains what size split system you may need, which features matter most, and which brands are best suited to family rooms and larger living areas.
What Size Air Conditioner Do I Need For My Living Room?
Living rooms generally require larger systems than bedrooms due to their size, usage patterns, windows, occupants and connection to other areas of the home.
| Living Room Size | Recommended Capacity | Typical Use |
|---|---|---|
| Up to 25m² | 3.5kW – 5.0kW | Small lounge rooms and enclosed living spaces |
| 25m² – 40m² | 5.0kW – 6.0kW | Standard family rooms and medium living rooms |
| 40m² – 60m² | 6.0kW – 7.1kW | Large living rooms and semi-open spaces |
| 60m²+ | 7.1kW – 9.5kW | Open living, dining and kitchen areas |
Why Living Rooms Need Larger Systems
Larger Floor Areas
Living rooms are usually much larger than bedrooms and require more cooling capacity.
More Glass
Large windows and sliding doors can increase heat load, especially during Perth summers.
More People
Family rooms often have more occupants, which increases heat and comfort requirements.
Appliances
TVs, sound systems and other electronics can add extra heat into the room.
Open Layouts
Living areas often connect to kitchens, hallways and dining rooms.
High Ceilings
Higher ceilings increase the amount of air the system needs to condition.
