Buying Guide For Whole House Mini Split Systems
When selecting a whole house mini split system, consider the following key factors to ensure you choose the best solution for your home’s needs:
BTU Capacity And Room Size
The cooling and heating capacity is measured in BTUs. Choose capacity based on the total square footage you want to condition. For multi-room setups, tri-zone or multi-zone systems like the ROVSUN 28000 BTU offer tailored climate control per room.
Energy Efficiency Ratings
SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings indicate efficiency. Higher SEER ratings (above 16-19) reduce energy consumption, yielding long-term savings.
Installation Type And Ease
Some models, like MRCOOL Easy Pro and Klimaire DIY, facilitate easier installation with pre-charged lines and plug-and-play connections, reducing professional fees. Evaluate if DIY installation suits your abilities or if you prefer professional setup.
Number Of Zones And Controls
Systems with multiple zones provide individualized temperature control in different areas, increasing comfort and efficiency. Check if the system includes remote or smart app controls for convenience.
Heating Capabilities And Temperature Range
If you need heating, ensure the unit’s heat pump covers your local winter temperatures, especially if it can operate below freezing temperatures for reliable warmth year-round.
Noise Levels
Look for ultra-quiet operation (below 35 dB) in indoor units to prevent disruptions in bedrooms or offices.
Warranty And Certifications
Verify certifications such as ETL and AHRI which indicate quality and safety standards. Choose systems with substantial warranty periods on parts and compressors for peace of mind.
