RP15AZ42AJ2NA Heat Pump System

RP15AZ
Cooling Efficiencies up to: 16 SEER2 / 11.7 EER2
Heating Efficiencies up to: 8.1 HSPF
Nominal Sizes: 1.5 to 5 Tons [5.3 to 17.6 kW] Cooling & Heating Capacities: 13.36 kBTU to 45.6 kBTU

*Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps must be matched with appropriate coil components to meet Energy Star. Ask your Contractor for details or visit www.energystar.gov.

Features and Benefits

  • Two-Stage Scroll Compressor: Features two speeds (high and low) of cooling and heating, providing more precise temperature control, lower humidity and greater efficiency when compared to single stage compressors
  • 7 mm Condenser Copper Coil1: Requires less refrigerant allowing for a smaller and lighter footprint while enhancing reliability
  • Inverted Reversing Valve: Allows for faster heat transfer with gravity assist shifting and reduced joint stress for increased reliability
  • PlusOne® Expanded Valve Space: 3 in. – 4 in. – 5 in. service valve space — provides a minimum working area of 27-square inches for easier access
  • PlusOne®Triple Service Access: 15″ wide, industry leading corner service access, two fastener, removeable corner and individual louver panels — makes repairs easier and faster
