This MRCOOL® Olympus 4th Gen condenser is a 48,000-BTU, 2-zone heat pump built to power up to 6 indoor air handlers, matched here with an 18K wall-mounted indoor unit and an 18K wall-mounted indoor unit for independent, room-by-room heating and cooling. The condenser is rated up to SEER2 24 and HSPF2-4 10.6, and it's built to keep running in outdoor temperatures as low as 5°F.
