Buying Guide For Cheap Mini Split Systems
BTU Capacity and Room Size Coverage
Select a mini split system with the appropriate BTU capacity for your space. Smaller rooms (up to 400 sq.ft.) require units around 9,000 BTU, while medium spaces (up to 750 sq.ft.) suit 12,000 BTU models. Larger areas (up to 1,000 sq.ft. or more) may require 18,000 BTU or higher.
Energy Efficiency Ratings
Look for units with high SEER2 ratings (Seasonal Energy Efficiency Ratio). Higher SEER2 values mean better energy savings and lower operational costs. Opt for systems with inverter technology that modulates compressor speed to save energy and maintain consistent comfort.
Heating and Cooling Features
Check if the mini split includes a heat pump for both heating and cooling, which provides versatile year-round use. Multipurpose modes such as auto, dry/dehumidification, fan-only, and turbo boost modes offer better control over indoor climate.
Installation and Controls
Consider models that simplify installation—DIY-ready systems reduce professional costs. Look for features like WiFi connectivity, smart remote control, and compatibility with voice assistants such as Alexa to maximize control convenience.
Noise Levels and Comfort Modes
Quiet operation is important for bedrooms or office environments. Choose systems with whisper-quiet modes and adjustable fan speeds. Additional comfort modes including sleep and eco modes help balance comfort and energy consumption.
Environmental Impact
Units using modern refrigerants like R32 are more eco-friendly. These refrigerants reduce greenhouse gas emissions compared to older types while maintaining cooling performance.
