What to consider when choosing an air conditioner
Compare room size, noise level and service options with a simple rule.
An incorrectly sized air conditioner reduces comfort and can increase energy use. Consider sunlight, ceiling height and heat sources as well as floor area.
Match BTU to the room
Floor area is a useful starting point for standard rooms, but an installer should confirm the final calculation.
- Often 9000 BTU for 20-30 m²
- Often 12000 BTU for 30-40 m²
- Allow more capacity for sunny or open-plan rooms
Review inverter and noise performance
Inverter systems hold temperature more steadily. Low indoor noise is especially important in bedrooms.
- Energy efficiency
- Night and quiet modes
- Operating range for heating
Treat installation as part of the purchase
Pipe length, outdoor-unit position and drainage directly affect the final result.
- What standard installation includes
- Extra pipe and cable cost
- Service and filter maintenance
