Key Features
Real-World Texas Examples
Houston Application
For a 550-1,000 sq ft master bedroom in Houston, the 18,000 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 18,000 BTU size handles 550-1,000 sq ft effectively, especially for rooms with good insulation. West-facing rooms may need the next size up (24,000 BTU).
