How to Choose Mini Splits
Cooling Capacity
Look for the cooling capacity measured in BTUs. A 12,000 BTU unit is suitable for about 450 to 600 square feet. If your space is larger, you may need a unit with a higher BTU rating for effective cooling.

Check the EER rating. Higher numbers mean better energy efficiency. Aim for at least a 15 EER rating to keep energy costs low while remaining comfortable.
Inverter Technology
Choose mini splits with inverter technology. This technology adjusts the compressor speed based on the temperature needs. It results in less energy use and longer-lasting units.
Heating Capability
Make sure the unit can also heat if you need year-round comfort. Look for a mini split that can maintain heat in temperatures as low as -4°F for reliable winter performance.
Noise Levels
Consider the noise level of each unit. Look for models with a decibel rating below 50dB for quiet operation, especially if it’s going into a bedroom or office.
