How to Choose the Right Mini-Split System for Your Space
BTU, zone count, SEER2, voltage, features — here's everything you need to make the right call without guessing.
Shop All Systems »Step 1: Match BTU to Room Size
| Room Size | BTU | Best For |
|---|---|---|
| 250-450 sq ft | 9,000 BTU | Small bedrooms, offices |
| 400-600 sq ft | 12,000 BTU | Average bedrooms, studios |
| 600-1,000 sq ft | 18,000 BTU | Larger rooms, open layouts |
| 1,000+ sq ft | 24,000+ BTU | Large areas, light commercial |
Step 2: Single-Zone or Multi-Zone?
Multi-Zone
One outdoor unit, several indoor heads. Each room has its own thermostat.
Shop multi-zone »Step 3: Account for Insulation and Sunlight
Poor insulation, vaulted ceilings, or lots of west-facing windows mean you should size up. When in doubt, use our free load calculator.
Step 4: Check the SEER2 Rating
Higher SEER2 = lower monthly bills. For rooms you use daily, 18+ SEER2 is worth it. See our full SEER2 guide.
