About it
The LG KUSXB121A is the outdoor unit of a ducted cold-climate heat pump that heats and cools through your home's ductwork. NRCan lists it with matching indoor equipment, for example KNSLB121A. Manufacturer documents list R-32 refrigerant and 208/230 V, single phase, 60 Hz. Confirm the full model numbers and matched system before purchase. A heat pump moves heat instead of burning fuel, so one system can heat and cool your home and can reduce fuel use. This outdoor unit is on NRCan's National Heat Pump Rebate eligible product list in matched systems (for example AHRI 215588570). The rebate is checked by the AHRI number of the whole matched system, and whether you qualify depends on your household, where and when it is installed, and the program rules, so confirm the exact system with your HVAC contractor.
