To determine the appropriate BTU rating for your space, start by measuring the square footage of the area you want to heat or cool.

• Insulation: Poor insulation may require a higher BTU rating.
• Climate: Extremely hot or cold climates may also necessitate additional BTUs for optimal performance.

• 9,000 BTU: Suitable for spaces up to 375 sq. ft.
• 12,000 BTU: Ideal for areas between 350–550 sq. ft.
• 18,000 BTU: Covers spaces from 550–800 sq. ft.
• 24,000 BTU: Best for areas measuring 800–1,050 sq. ft.
• 36,000 BTU: Designed for larger spaces between 1,050–1,550 sq. ft.
