Buying Guide
What size do I need?
Choose a 24,000 BTU unit for spaces up to about 1,500 square feet. For open-plan layouts, consider a mini split for targeted cooling in specific zones or multiple zones for even comfort.
Window vs. mini split — which is easier?
Window units are typically easier and cheaper to install but are limited to a single zone. Mini splits offer zone control and year-round heating, but require professional installation and higher upfront costs.
How important is energy efficiency?
Look for inverter technology and Energy Star labeling. These features reduce operating costs by varying compressor speed to meet cooling demands, rather than running at full power continuously.
What features should I prioritize?
- Smart controls: App or voice control for convenient scheduling and remote operation.
- Multiple modes and speeds: Auto Cool, Dry, and Sleep modes enhance comfort and efficiency.
- Filter accessibility: Front-access filters simplify maintenance and airflow.
- Auto Restart: Useful for spaces prone to power interruptions.
Installation considerations
For window units, ensure window sash dimensions match the unit and verify electrical requirements (voltage, circuit capacity). For mini splits, plan for inner wall mounting, condensate drainage, and professional commissioning if needed.
