Upgrade your heating and cooling strategy with the Hessaire DIY 18,000 BTU Ductless Mini-Split Heat Pump. Designed for residential spaces up to 900 square feet that need reliable, efficient temperature control, this system delivers both warm and cool air without the need for bulky ductwork.

Part of Hessaire’s Standard DIY Series, the mini-split uses environmentally friendly R-32 refrigerant and arrives ready for homeowner installation. The result is a practical solution that balances performance, flexibility, and cost savings.

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 1/4 x 1/2" 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.
