The unit is designed to be energy efficient, with a SEER rating of 17 and a noise level of 53 dB. It also has a 36 pint capacity that can cover up to 750 square feet.

This mini split air conditioner features five working modes for all year comfort: auto, cool, dry, heat and fan mode. It also has four available fan speeds low/medium/high/auto as well as sleep mode, ECO mode, iFEEL turbo function. With these features you can customize the unit to your specific needs and preferences. In addition, the handy remote control allows you to control the unit from your comfortable bed or sofa conveniently. Plus, the smart 0.5 24 hour timer and low noise operation ensure a peaceful sleep time.

The outdoor unit also features an auto defrost function to avoid damage and improve energy efficiency. This powerful and energy saving split AC unit is perfect for home, office, business or commercial use. Another great feature is its self cleaning function at high temperature of 134.6 and a washable filter which automatically cleans its interior this is an important feature since it helps keep your AC unit free from dirt build up which can reduce its efficiency over time.
