The Soleus Air has 12,000 BTU cooling with 10,000 BTU of Heat, extra efficient Inverter compressor, and Wi-Fi. Sized for extra-thick walls up to 12.5″ thick (including a sill). The Wi-Fi App gives you the ability to cool or heat your room anywhere. Due to Soleus’ industry-exclusive Saddle design, the unit sits low and over the wall, eliminating the chances of the unit falling out of the window and any need to drill holes in the window for support. Sleep Mode automatically moderates set temperatures at night to conserve energy. Featuring a washable filter, which captures dust from the air and keeps your air conditioner working efficiently.
