Living Room Air Conditioning
A living room is usually the largest space in the home, so it needs real capacity — 12,000–24,000 BTU depending on floor area, ceiling height and how many people use it. A split system is the popular choice for permanent, whisper-quiet cooling that also heats in winter.
For open-plan living, a multi-split or ceiling cassette spreads air evenly. A high-BTU portable is the quick fix if you can’t fit an outdoor unit.

Living Room Air Conditioning — frequently asked
How many BTU for a living room?
Typically 12,000–24,000 BTU depending on floor area, ceiling height, glazing and occupancy. A large open-plan living room may need more — size it with our BTU calculator.
Split or portable for a living room?
A split system is the better long-term choice: quieter, more efficient and it also heats. A portable unit suits renters or a room where an outdoor unit isn’t possible, but expect more noise.
Can one unit cool an open-plan kitchen-living room?
Often a single split struggles with the heat from cooking. A multi-split with a second indoor unit in the kitchen zone, or a higher-BTU cassette, is usually the answer.
