Buying Guide
- Room size: Match BTU to space. Up to 400 sq ft (9,000 BTU), 350–700 sq ft (8,000–14,000 BTU) depending on layout and insulation.
- Portability and setup: Look for caster wheels, built-in handles, and straightforward venting; windowless or evaporative models offer alternative placement in tight spaces.
- Modes and features: Cooling, dehumidifying, and fan modes add versatility. Sleep, timer, and auto-evaporation reduce maintenance and energy use.
- Energy efficiency: Consider models with efficient refrigerants and CEER ratings; for long daily use, an energy-conscious unit saves operating costs.
- Smart controls: If you want remote access, Wi‑Fi connectivity and voice control can improve daily convenience but require stable network.
- Installation considerations: Ensure proper venting or window seal kits where required. In windowless designs, confirm the water tank capacity and drainage options.
