This self-adhesive tape is versatile for sealing door frames, windows, and air conditioning units, available in white to complement most window frames. Strong adhesion helps maintain a weather-tight seal, reducing lost cooled air and keeping your attic comfortable.
Buying Guide for Attic Window Air Conditioners
Selecting the best attic window air conditioner involves several key considerations to ensure effective cooling and energy efficiency.
Cooling Capacity & Room Size
The unit’s BTU rating should match your attic’s square footage for optimal performance. Small attics of up to 150 sq ft generally require 5,000 BTU units, while larger spaces may need higher capacity units. Oversized units waste energy by cycling off too quickly, reducing dehumidification.
Noise Level
Because attics are often used as bedrooms or workspaces, low noise operation is important. Units with noise ratings around 50 dBA or less provide quiet environments conducive to sleep or concentration.
Energy Efficiency
Look for units with high CEER ratings or ENERGY STAR certification for energy savings over time. Inverter technology also reduces electricity consumption by adjusting compressor speeds to match cooling needs.
Installation and Compatibility
Measure your attic window size to ensure the air conditioner fits securely. Many units come with installation kits for quick setup. Consider how weather stripping can seal gaps around the unit after installation.
Controls and Features
Mechanical controls offer simplicity, but electronic or smart controls provide precision and remote access. Features like multiple fan speeds, temperature settings, timers, and Wi-Fi connectivity add convenience.
Maintenance
Choose units with washable or reusable filters to keep air clean and the system running efficiently. Easy filter access encourages regular cleaning.
Additional Accessories
Weather stripping or insulation tape is useful to improve sealing and prevent cooled air from escaping attic windows around the air conditioner unit.
