Best BTU Options for 1,000-1,250 sq ft
For 1,000-1,250 sq ft rooms, start with 24,000 BTU for 1,000 sq ft spaces, but 30,000 BTU is often necessary for rooms closer to 1,250 sq ft. Commercial spaces or rooms with high ceilings may require multiple units.
For 1,000-1,250 sq ft, you have several BTU options:
- 24,000 BTU: Ideal for 1,000-1,250 sq ft with standard conditions
- 30,000 BTU: Ideal for 1,000-1,250 sq ft with challenging conditions (high ceilings, poor insulation, extreme heat)
Texas-Specific Considerations
1,000-1,250 sq ft spaces in Texas benefit from multiple units for zone control. Single large units work but may struggle with air circulation. Consider multiple 18,000-24,000 BTU units instead of one 30,000 BTU unit for better comfort.
