Which one should I buy?
- Choose LETO if you're heating or cooling one room, your winters rarely drop below about 5°F (-15°C), and upfront price matters most.
- Choose AURA if you get cold winters, want the lowest running costs, need several rooms on one outdoor unit, or want the 10-year compressor warranty.
