Buying Guide for Duct Air Conditioners
Cooling Capacity and Room Size
When selecting a duct air conditioner, match the BTU rating to your room size. Larger spaces require units with higher BTU (12,000 to 16,000+) for adequate cooling. Smaller rooms do well with lower BTU units like 5,000 BTU window ACs. Accurately measuring room square footage helps ensure efficient and effective cooling.
Type and Installation
Choose between window air conditioners, portable units with ducting, or ductless mini-split systems. Window units are typically easier to install but require a suitable window. Portable ACs provide flexibility and usually need a vent hose for exhaust. Consider if you prefer permanent installation or mobility.
Energy Efficiency
Look for units with high CEER ratings or Energy Star certification. Energy efficient units consume less power, helping reduce electricity bills. Inverter compressors and dual-hose designs enhance cooling without excessive energy use.
Noise Levels
Operating noise is critical if the AC unit will be placed in bedrooms or quiet spaces. Units advertising noise levels below 50dB are better for undisturbed sleep and working environments.
Smart and Remote Controls
Modern air conditioners with app compatibility and remote controls offer better usability. Voice command features add convenience but are optional depending on your preferences.
Duct and Vent Maintenance
Maintaining clean ducts and vents using products like PermaSafe Kits and air vent filters extends the lifespan of your AC system and improves indoor air quality. Replacement filters and hose covers help keep airflow unrestricted and reduce allergens.
Additional Features
- Modes like dehumidifier and fan increase versatility.
- Timers and sleep modes adjust operation for comfort and energy savings.
- Dual-hose systems improve cooling efficiency by separating intake and exhaust airflow.
