Buying Guide
BTU Capacity and Room Size represent the most critical factors in mini split selection. Calculate approximately 20 BTUs per square foot for standard ceiling heights, adjusting for factors like insulation quality, window size, and sun exposure. Undersized units struggle to maintain comfort, while oversized systems cycle inefficiently.
SEER2 ratings indicate energy efficiency, with higher numbers representing better performance. Look for ratings above 19 SEER2 for optimal energy savings. Modern inverter technology adjusts compressor speed continuously, providing superior efficiency compared to traditional on-off cycling systems.
Installation requirements vary significantly between models. Consider electrical requirements (115V vs 208-230V), mounting space, and refrigerant line length. Pre-charged systems simplify installation but may require professional service for optimal performance. Factor installation costs into your budget planning.
Smart features and connectivity enhance convenience and energy management. WiFi capability enables remote monitoring and control, while Alexa or Google Assistant integration provides voice control. Consider which smart home platforms you currently use for optimal compatibility.
Noise levels affect comfort, particularly in bedrooms or quiet spaces. Look for units operating below 45 decibels for minimal disturbance. Indoor and outdoor noise ratings may differ, so consider both measurements when evaluating options.
Climate considerations influence heating performance in colder regions. Heat pump functionality typically decreases as outdoor temperatures drop, with some units maintaining operation to -4°F while others stop at higher temperatures. Verify cold weather performance specifications for your local climate conditions.
