Key Features and Benefits of the Hessaire DIY 18,000 BTU Ductless Mini-Split Heat Pump

• Inverter Compressor: The variable-speed compressor automatically adjusts output to match demand, reducing energy waste and helping maintain a steady set temperature.
• High Efficiency: An industry-leading 21.0 SEER2 rating for cooling and 9.8 HSPF2 rating for heating means lower operating costs over time, a smart choice for energy-conscious properties.
• DIY Installation Kit: Pre-charged refrigerant lines, quick-connect fittings, and step-by-step instructions let you tackle installation without specialized HVAC tools.
• Wi-Fi Remote Access: Pair the system with your smartphone to adjust the operating mode, fan speed, or scheduling from anywhere, adding convenience for busy schedules or rental units.
• Ultra-Quiet Indoor Operation: Sound levels as low as 48 dB help keep bedrooms, offices, and media rooms peaceful while the system is running.
• Eco-Friendly Refrigerant: The R-32 refrigerant has a lower global-warming-potential than other legacy formulas, supporting environmental goals and aligning with modern regulatory standards.

DIY made simple

Traditional mini-split installs typically require a professional with specialized tools that most DIYers don't have access to or know how to use. Hessaire removes those barriers by pre-charging the 16-foot line set with R-32 refrigerant and sealing the connections with quick-couplers. That means you handle the wall bracket, drill a small pass-through hole, run the lines, and tighten two flare nuts. A detailed manual and labeled components will guide you through each step, streamlining the process to a straightforward afternoon project.
