How to read this page
- The smaller unit usually costs less to run, but sizing should still match the room rather than chasing the lowest wattage only.
- The 12000 BTU option can be worth it if undersizing would force longer runtime or worse comfort.
- Use the same cooling hours on both sides before judging the tradeoff.
