Key Features and Benefits of the Hessaire DIY 24,000 BTU Ductless Mini-Split Heat Pump

• Inverter Compressor: The variable-speed compressor automatically adjusts its output to match demand, reducing energy waste and helping maintain a steady set temperature.
• High Efficiency: An industry-leading 19.5 SEER2 rating for cooling and 8.5 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 50 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 Installation

This DIY 24,000 BTU ductless mini-split heat pump arrives with the key components already factory pre-charged with refrigerant. The 16-foot line set features quick-connect couplings, so you simply route the pipes through the exterior wall, tighten the flare nuts to the specified torque, and open the service valves, no vacuum pump or gauges required. You will still need to supply a dedicated electrical circuit and follow local codes, but the simplified refrigerant work lets confident homeowners finish the bulk of the project themselves.
