Choosing the correct mini split size is one of the most important parts of comfort, efficiency, and long-term system performance.

That’s why we built our Mini Split Sizing Guide Center to help homeowners, garages, workshops, additions, cabins, and whole-home applications better understand proper HVAC sizing before purchasing a system.

Our sizing guides include:
✓ Single-Zone Systems
✓ 2-Zone Systems
✓ 3-Zone Systems
✓ 4-Zone Systems
✓ 5-Zone Systems
✓ 6-Zone Systems

Inside the guides, you'll find:
• BTU sizing recommendations
• Square footage guidance
• Garage & workshop sizing tips
• Ceiling height considerations
• Oversizing & undersizing mistakes
• Multi-room planning advice
• Real-world HVAC sizing insight

Whether you're installing a system yourself or working with a contractor, these guides were designed to help simplify the process and provide a better starting point for choosing the right system configuration.
