Key Features
Real-World Texas Examples
Houston Application
For a 400-550 sq ft master bedroom in Houston, the 12,000 BTU unit works well, but ensure proper dehumidification. Houston's humidity requires systems that can effectively remove moisture while cooling.
Dallas Application
In Dallas, the 12,000 BTU size handles 400-550 sq ft effectively, especially for rooms with good insulation. West-facing rooms may need the next size up (18,000 BTU).
