Buying Guide: Key Considerations For Attic Mounted Air Conditioners
Choosing the best attic mounted air conditioner comes down to understanding your specific cooling needs and home setup. Consider the following factors thoroughly:
Cooling Capacity & Room Size
Select a unit with adequate BTUs to cover your attic or room size. Undersized units will struggle to cool effectively, while oversized units may cycle too frequently, wasting energy.
Installation Type
Determine if a through-the-wall or window installation is feasible. Through-the-wall units require wall cutouts but provide permanent, efficient cooling without obstructing windows.
Energy Efficiency
Check for models with high Energy Efficiency Ratios (EER) or ENERGY STAR ratings. More efficient units reduce operating costs and environmental impact.
Smart Features & Controls
Smart connectivity such as Alexa or Google Assistant integrations, remote controls, and programmable timers enhance user convenience and control.
Noise Levels
Quiet operation is key in living spaces. Units specifying noise levels below 55 dBA are generally suitable for bedrooms and offices.
Additional Functionalities
- Dehumidification: Some models remove excess moisture to improve air quality.
- Heating Capability: Dual-function units offer year-round comfort.
- Filter Maintenance: Easily accessible, washable filters extend the lifespan and improve HVAC performance.
Space & Design
Compact designs and oscillating fans can enhance airflow distribution without occupying much room, an important feature for tight attic spaces.
Evaluating these elements in combination will help you select an attic-mounted air conditioner that provides efficient, consistent cooling while meeting your lifestyle and space requirements.
