The standout elements include DC inverter technology for better efficiency and Alexa compatibility, allowing voice or remote control from anywhere via the app. VIEW ON AMAZON Performance The LETO Series impresses with a balance between performance and efficiency, offering reliable climate control for rooms up to 750–1,000 square feet. The 18000 BTU capacity is ideal for larger bedrooms, living rooms, garages, and even RVs. Cooling Performance Thanks to the DC inverter compressor, the unit adjusts its power dynamically based on current cooling needs, which reduces energy consumption and improves temperature consistency. It reaches the desired room temperature quickly and maintains it steadily with minimal noise or fluctuation. Customers report rapid cooling even on very hot days, and the Turbo function is especially effective when an immediate drop in room temperature is needed. Unlike traditional on-off compressor systems, the inverter keeps the room at a more stable comfort level without sudden shutdowns or noise spikes. Heating Function This model includes a heat pump system rated to work efficiently down to 5°F (-15°C), making it a great year-round climate control solution. In colder climates, while it may not entirely replace a furnace, it provides meaningful supplemental heating — perfect for spring and fall or regions with mild winters. Energy Efficiency With a SEER2 rating of 19, the Senville LETO Series is classified as a high-efficiency model, though not the absolute highest in its class. It strikes a smart balance between performance and cost. Many users noticed no significant increase in energy bills, even with regular use, which speaks to the value of inverter technology. Noise Levels The indoor unit is notably quiet, operating in the range of 24–38 dB, which is comparable to the rustling of leaves. This makes it ideal for bedrooms, nurseries, or offices where noise sensitivity is a concern. Outdoor condenser noise is also relatively low, thanks to its brushless DC motor and vibration-reduction design.
