With a high SEER rating of 19 and an HSPF of 11, it provides superior energy savings even at temperatures as low as -13°F.

Superior Heating & Cooling Performance

  • 19 SEER2: delivers strong seasonal cooling efficiency that helps trim energy costs through the summer months.
  • 11 HSPF2: provides efficient heat-pump warmth for cost-effective comfort when the temperature drops.
  • 12.5 EER2: holds solid efficiency under peak-load conditions on the hottest days of the year.
  • Cold-Weather Output: rated heating capacity of 25,000 BTU at 47F, 18,800 BTU at 17F, 19,600 BTU at 5F, with a COP of 2.3 at 5F for dependable heat as it gets cold.
  • ENERGY STAR Cold Climate: certified for reliable performance in genuinely cold climates, not just mild weather.
  • Wide Operating Range: engineered to cool and heat across a broad outdoor temperature range for year-round comfort.

Advanced Technology

  • Inverter Compressor: continuously varies its output to match demand instead of cycling fully on and off, saving energy and holding steady temperatures.
  • R-454B Refrigerant: uses an eco-friendly, low-GWP refrigerant that meets the latest environmental requirements.
  • A2L Safety Sensor: a factory-installed refrigerant sensor adds an extra layer of built-in safety.
  • AHRI Certified: performance ratings are independently verified, so you know exactly what you are buying.
  • Variable-Speed Operation: ramps smoothly to keep rooms at a consistent temperature while minimizing energy use.

Whisper-Quiet Operation
