Buying Guide for Attic Window Air Conditioners
Cooling Capacity and Room Size
When selecting an attic window air conditioner, BTU (British Thermal Unit) rating is a critical factor directly related to the size of the space. Small attic rooms under 150 sq ft usually require units from 5,000 BTU, while larger attic spaces may need 10,000 to 12,000 BTU for effective cooling. Overpowered units can waste energy, while underpowered units struggle to maintain desired temperatures.
Noise Level Considerations
Attics often serve as bedrooms or work areas where low noise is essential. Look for units rated below 55 dBA ideally. Specialized designs, like Midea’s U-Shaped model, significantly reduce noise by insulating external sound and mechanical vibrations, making them excellent choices for noise-sensitive users.
Energy Efficiency
Energy saving features, such as inverter technology and high CEER ratings, ensure your attic AC runs economically without inflating electric bills. Look for ENERGY STAR-certified units or those highlighting energy reductions over conventional models.
Installation and Fit
Window size and type in your attic will determine installation options. Many modern window air conditioners come with easy install kits that help seal and secure the unit properly. Units like the GE models come with comprehensive mounting kits suited for quick setup.
Smart Features and Controls
Smart controls allow temperature and timer adjustments via smartphone or voice assistants, improving convenience for attic users. Wi-Fi-enabled units like the GE AWCS12WWA and Midea U-Shaped enable remote usage, which can be helpful if the attic is not frequently occupied.
Maintenance
Air filters that are washable or reusable extend the lifespan of your unit and improve air quality. Regular maintenance via easy-to-access filters is necessary to keep your AC efficient, particularly in dusty attic environments.
Additional Accessories
Consider adding weather stripping or insulation tape around the window or door frame to ensure minimal air leaks around the air conditioner. Products like the Dualplex High Density Foam Weather Stripping provide effective sealing, enhancing the AC’s overall efficiency and preventing draft.
