Buying Guide
- Sizing and capacity: For spaces up to 1500 sq ft, 24,000 BTU models are common. If you have a tall ceiling or multiple rooms, you may need a larger single-zone unit or consider a multi-zone setup.
- Efficiency ratings: Look for SEER2 values in the 18–21 range. Higher SEER2 means lower operating costs but potentially higher upfront price.
- Install considerations: Most units require professional installation, including refrigerant charging and electrical connections. Ensure adequate outdoor clearance and proper drainage.
- Smart features: If you want remote operation and voice control, prioritize models with built-in WiFi and compatibility with Alexa or Google Assistant.
- Operating range: Check the unit’s rated operating temperatures. Some models perform better in very hot or very cold climates.
- Noise levels: For bedrooms or study areas, choose models explicitly labeled as quiet, with decibel ratings around 30–32 dB in cooling mode.
- Maintenance: Self-cleaning features and accessible filters simplify upkeep. Plan for annual professional inspections to ensure refrigerant integrity.
- Installation kit and piping length: Some units include a full installation kit; others require additional copper pipes. Consider line length limits (often 25 ft) for optimal performance.
