Buying Guide
- Room size and BTU: Choose about 20 BTU per square foot for small rooms (up to 150 sq ft). For larger small rooms or open-plan spaces, consider up to 8,000 BTU with portable options.
- Noise levels: Look for units with stated dBA ratings in low-speed modes (roughly 50–55 dBA for quiet operation). Consider sleep or night modes for steady, uninterrupted rest.
- Installation flexibility: Window units are compact and straightforward; portable units add flexibility but may require venting kits and have constraints on exhaust routing.
- Controls and maintenance: Mechanical controls offer simplicity; washable or replaceable filters support long-term efficiency and air quality.
- Energy efficiency: Inverter or energy-saving modes reduce electricity use. Energy Star-rated models typically deliver solid efficiency for longer-term savings.
- Durability and warranty: For frequently used cooling, select models with stable performance histories and accessible replacement parts.
