Buying Guide
- Cooling Capacity vs. Room Size — Choose BTUs to match room size. Larger spaces need higher BTU units (e.g., 10,000–11,800 BTU) to maintain comfortable temperatures.
- Through-Wall Sleeve Compatibility — Most units specify sleeve width requirements. Verify sleeve compatibility (often 24.5″–27″) before purchasing.
- Dehumidification Needs — If humidity control is important, pick models with built-in dehumidifiers and a dedicated dehumidification mode.
- Energy Efficiency — Look for units with efficient refrigerants (R-32) and high EER values to reduce operating costs.
- Supplemental Heating — If you need year-round comfort, consider models with supplemental heat, but treat them as secondary heat sources in cool climates.
- Installation Considerations — Some models are not suitable for window installation and require a proper through-wall sleeve and trim kit for a clean finish.
- Quiet Operation — For bedrooms or study spaces, prioritize models marketed for quieter performance or night modes.
