WHHP Series Heat Pump Units
1.5 – 2.5 Tons
R-454B
The space and cost saving features of through the wall split heat pumps continue to be important to architects, engineers, multi-family developers, and today’s projects that demand higher efficiency equipment.
First Co. is proud to offer the high efficiency WHHP. By using the industry’s latest state-of-the-art components such as ECM motors, high efficiency compressors, and enhanced coil technology, the WHHP heat pump achieves 11.9 – 13.0 SEER2 when combined with its matching First Co. high efficiency air handler. In addition, the heat pump’s unique propeller-type fan blade operates at a slower speed and is much quieter than traditional squirrel cage type blowers.
