Buying Guide
What size should you choose? Measure the room and compare BTU capacity to space. Larger spaces benefit from higher BTU models (e.g., 24,000 BTU), while smaller rooms can do well with 9,000–12,000 BTU units to avoid overcooling.
Which features matter most? Look for inverter technology (higher SEER2 ratings indicate better efficiency), all‑season heating, and smart controls (remote apps or voice assistants). Self‑cleaning or anti‑mold features help maintenance but require regular filter care.
Where will you install it? Consider wall‑mount or ceiling‑cassette options and outdoor unit clearance. Pre‑charged units simplify setup, but some installations still require professional refrigerant charging and line‑set routing.
Energy efficiency versus cost. SEER2 and inverter performance directly affect energy bills. If you run AC year‑round, prioritize higher SEER2 ratings and features like Eco Mode and Sleep Timer to balance comfort with savings.
Smart integration and user experience. Alexa or app control adds convenience; ensure your home network supports reliable connectivity and that the app offers remote scheduling and temperature adjustments.
