Key Considerations When Choosing a DIY Mini Split Unit

Before you dive into the world of DIY mini split units, consider the following factors to ensure the best investment for your specific needs:

1. **Cooling capacity**: Measure your room size in square feet and choose an appropriate cooling capacity. Foraccuratecooling, follow the rule of 20: a room measuring 150-200 sq. ft. would require a 14,000-16,000 BTU unit, while a 225-300 sq. ft. room would need a 18,000-22,000 BTU unit.

Efficiency and Energy Savings

Look for units with an Energy Efficiency Ratio (EER) rating. A higher EER value indicates better energy efficiency, saving you money on utility bills. Also, consider units with multiple operating modes like cooling, heating, and fan-only to maximize flexibility and reduce energy consumption.
