Ruud Endeavor® Line Achiever® Series iM Heat Pumps

Features and Benefits

• Two-Stage Scroll Compressor: Offers two speeds (high and low) for precise temperature control, improved humidity management, and enhanced efficiency compared to single-stage compressors.
• Inverted Reversing Valve: Facilitates faster heat transfer with gravity assist shifting and reduced joint stress for increased reliability.
• PlusOne® Expanded Valve Space: Provides 3 in. – 4 in. – 5 in. service valve space, offering a minimum working area of 27 square inches for easier access.
• PlusOne® Triple Service Access: Features 15 in. wide, industry-leading corner service access with two fasteners and removable corner and individual louver panels for easier and faster repairs.
• Designing for Sustainability with Low GWP: Meets the EPA's 2025 global warming potential (GWP) limit of 700 for refrigerants, utilizing R-454B which has a 78% lower GWP than previous-generation refrigerants, contributing to sustainability goals while maintaining energy efficiency.
• PlusOne® Refrigerant Detection System™: An integrated system with an A2L sensor and mitigation board for easier commissioning and simplified wiring. It offers compatibility with any 24V thermostat and automatically pauses outdoor unit operation if excess refrigerant is detected.
