The bedroom is where AC performance matters most. A unit that's too noisy, too cold, or inefficient can seriously impact your sleep quality.
Key Bedroom AC Requirements
1. Quiet Operation
This is the #1 priority for bedrooms. Look for:
- Indoor unit noise: Under 26 dB (whisper quiet)
- Sleep mode: Reduces fan speed and noise at night
- Inverter compressor: No on/off cycling noise
2. Sleep Mode Features
Good sleep mode should:
- Gradually raise temperature (body needs less cooling while sleeping)
- Reduce fan speed
- Dim or turn off display lights
- Maintain consistent, gentle airflow
3. Right Sizing
Bedroom AC sizing:
- Small bedroom (10-15 sqm): 9,000-12,000 BTU
- Medium bedroom (15-20 sqm): 12,000-15,000 BTU
- Large bedroom (20-25 sqm): 15,000-18,000 BTU
Don't oversize—larger units cycle on/off frequently, causing temperature swings and noise.
Best Features for Bedrooms
- Timer function: Auto-off after you fall asleep
- Gentle airflow: Indirect air distribution to avoid drafts
- Auto-restart: Resumes after power outage
- Mosquito deterrent: Some units have ultrasonic features
What to Avoid
- Window AC (too noisy for most bedrooms)
- Units without sleep mode
- Outdoor unit placement below bedroom window
- Oversized units (short cycling = poor comfort)
Installation Tips
- Position airflow away from bed (no direct draft on face/body)
- Place outdoor unit away from bedroom exterior wall
- Consider wall-mounted unit above bed headboard for indirect air
