Buying Guide
What should I consider when choosing an air conditioner for Chinese homes?
- Room size and BTU capacity: Match cooling output to your space. Smaller rooms (<150 sq ft) typically do well with 5000 BTU units; larger spaces may require 8000–10000 BTU portable units.
- Window vs. portable: Window units save floor space but require a window fit; portable units offer flexibility but can be louder and take floor area.
- Energy efficiency: Look for units with energy-saving modes, sleep settings, and efficient refrigerants to minimize electricity use in hot summers.
- Maintenance needs: Washable filters simplify upkeep; consider units with easy filter access for frequent dust-heavy environments.
- Climate suitability: In dry climates, evaporative coolers can be effective; in humid climates, dehumidification-focused units may perform better.
- Installation and compatibility: Check window kit compatibility and whether installation is straightforward without professional help.
