Buying Guide for Mini Split Heat Only Systems
When selecting a mini split heat only system, consider these key factors to ensure you choose the ideal unit for your needs:
Heating Capacity
Choose a BTU rating that matches the size of the room or area to be heated. For example, 9,000 BTU works well for smaller spaces around 400 sq. ft., while 12,000 BTU is sufficient for rooms up to 750 sq. ft. Oversized units waste energy; undersized will insufficiently heat.
Energy Efficiency
Look for systems with high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. Inverter technology is crucial for energy savings since it adjusts compressor speed to meet heating demand precisely.
Refrigerant Type
Modern eco-friendly refrigerants like R32 offer better environmental profiles and performance compared to older refrigerants. Opt for units using R32 refrigerant to minimize environmental impact.
Installation Kit and Support
Consider whether the mini split comes with a complete installation kit for easier setup. Additionally, robust mounting brackets and vibration control components improve system stability and reduce noise.
Control Features and Convenience
Remote controls, WiFi connectivity, timers, and multiple operational modes enhance usability. Features like sleep mode, eco mode, and turbo functions provide greater control over comfort and energy use.
Noise Levels
Quiet operation is essential for bedrooms or living rooms. Look for units with noise ratings below 30 decibels for a peaceful environment.
Warranty and Certification
Choose mini split systems that are AHRI certified to ensure quality standards, along with strong manufacturer warranties to protect your investment.
