Buying Guide: Key Purchase Considerations
- BTU sizing: Select a unit close to the room size (roughly 400–750 sq ft for 10k–12k BTU). Oversized or undersized units reduce comfort and efficiency.
- Energy efficiency: Look for SEER2 ratings and inverter technology to minimize energy use over the long term.
- Electrical requirements: Some units require 208/230V or specific circuit capacity. Verify your electrical setup before purchase.
- Climate suitability: If you experience very cold or very hot seasons, ensure the unit supports heating at low temperatures and cooling at high temps.
- Smart control: Wi‑Fi, app control, and compatibility with voice assistants can simplify daily use.
- Installation kit: Check if the installation kit is included and whether professional installation is recommended or required in your area.
- Dehumidification and multi-mode function: If you want year-round comfort, ensure the unit supports dry or dehumidify modes in addition to cooling and heating.
