  • Product Overview

    The Soleus SG-TTW-12ESE is an efficient, durable though-the-wall air conditioner. It offers 12,000 BTUs of cooling power, making it a great choice for rooms up to 500 square feet. This Energy Star-qualified Soleus model earned an Energy Efficiency Ratio (EER) of 9.4 thanks to its efficient design and features. A fully-functional remote control, 24-hour programmable timer, and digital thermostat make this a convenient thru-wall AC for individual rooms or small apartments.

    Energy Star-Rated Design

    All through-wall ACs are extremely efficient since they seal your room, but Energy Star models have been recognized by the government as efficient, money-saving choices. Features that save you money on energy costs include a programmable timer that ensures it only runs when needed and a digital thermostat that maintains your set temperature without over-cooling.

    The Soleus SG-TTW-12ESE Thru-Wall AC also features 2 modes to conserve energy: Its Sleep mode uses a low fan speed for quiet operation while you sleep. Energy-Saver mode turns off the compressor once your set temperature is met and only kicks back on once it's needed. You can also use fan-only mode to circulate room air on mild days when cooling isn't needed. 

    Simple, Secure Installation

    The Soleus SG-TTW-12ESE is designed for through-wall installation, which provides powerful cooling in rooms without an available window. For a new in-wall installation, this model easily fits inside the Soleus Air SG-TTWSL Universal Through-the-Wall Sleeve (sold separately). If you have an existing wall sleeve, check the dimensions--you may be able to use it for your new Soleus window AC. 

    *Note: If you don't have an existing through-the-wall sleeve, the Soleus SG TTWSL sleeve must be purchased to install this model correctly.

    Additional Features

    • Four Fan Speeds: Choose between low, medium, and high fan speeds. You can also select Auto speed, which chooses a speed based on your set room temperature. 
    • Remote Control: This impressive remote control lets you set your room temperature, fan speed, and change the mode. 
    • Moisture Control: The Soleus Air 12,000 BTU AC provides cool, dry air by removing up to 81.6 pints of excess moisture per day.
    • Washable Air Filter: A reusable air filter saves you money and ensures efficient operation. Rinse the air filter every month to remove collected dust particles.
    • Adjustable Airflow: Four-way air direction control lets you guide cool air to any location in your space.​
    • Auto Restart: In the event of a power failure, the Soleus SG-TTW-12ESE Through-the-Wall AC will automatically restart and resume operation in the last programmed settings once power is restored.​
    • Digital Display: The digital display screen shows the current room temperature and the remaining operation time when the timer is set.​
    • 24-Hour Timer: Program your AC to start up or power down in 30-minute intervals for up to 24 hours. This is commonly used before bed time or right before customers arrive home from work.


    Packed with features for both convenience and efficient operation, this popular Soleus model will make replacing an old thru-wall unit an easy decision.  

    What Customers Love

    • Effficient Design Saves Money and Energy: A 9.4 EER, multiple efficient modes, and programmable features help this model earn an Energy Star-rating for energy- and money-saving operation.
    • Powerful Cooling: This 12,000 BTU thru-wall air conditioner can cool areas up to 500 square feet so is ideal for large rooms or small apartments. 
    • Endless Features: You won't find many room ACs with more programmable features and modes than this one. 

    Things To Consider

    • Permanent Installation: While thru-wall ACs are extremely efficient, they also require permanent installation, a wall opening, and sleeve for proper installation.
    • Voltage Requirements: This powerful model requires a 208-volt outlet and NEMA 6-15P plug, so make sure your space is wired appropriately before purchasing.
