Buying Guide
What should you consider before buying a mini split?
- Capacity: Match BTU to room size. Most 12,000 BTU units cover up to about 750 sq ft, but actual needs vary with ceiling height, sun exposure, and insulation.
- Efficiency: Look for SEER2 and HSPF2 values. Higher numbers generally mean lower ongoing energy costs.
- Climate control features: ECO or sleep modes reduce energy use. Inverter compressors improve efficiency by avoiding on/off cycling.
- Sound: Sleep-friendly models can run as low as 26–30 dB in low or sleep modes; consider placement to minimize noise impact.
- Installation considerations: Outdoor unit placement, pre-charged systems, and refrigerant type affect performance and cost. Some models are pre-charged for easier DIY setup, while others may require professional installation.
- Controls and connectivity: APP control and remote access add convenience but verify compatibility with your devices and Wi-Fi networks.
