Optimized Technology for Better Integration

The YORK® variable refrigerant flow (VRF) low ambient heat pump unit performs in an extended operating temperature range: outdoor ambient temperatures as low as 14°F (-10°C) in the cooling mode and as low as -13°F (-25°C) in the heating mode. Its dual fan design increases airflow up to 23% while lowering sound levels, and its advanced inverter compressor modulates refrigerant flow to indoor units for precision comfort. This heat pump offers extended connection ratios of up to 150%, making it one of the best in the industry.
