Buying Guide: Key Considerations for Selecting a Split AC System
- Space and zoning: Determine the total square footage and whether you need one-zone or multi-zone cooling. Multi-zone units provide better comfort in evenly heated or cooled homes.
- Energy efficiency: Compare SEER2 and HSPF ratings. Inverter-driven models adjust power use for efficiency and consistent temperatures.
- Installation needs: DIY-ready units save time but may still require basic electrical work; ducted systems typically need professional installation.
- Climate compatibility: Consider operating temperature ranges. Units rated for very low or very high outdoor temps perform better in extreme climates.
- Controls and smart home integration: Look for compatibility with WiFi, Alexa, or Google Assistant for convenient management.
- Maintenance and warranties: Check what parts are included in the warranty and whether self-service features are available without voiding coverage.
