The company announced its new Champion Ultra heat pump, a residential single-package unit with up to a 13 seasonal energy-efficiency ratio. Designed for quiet operation, the Champion Ultra heat pump features a rigid top panel and embossed base pan to reduce vibration noise. Enhanced fin coils assist in quieting operating sounds, and the compressor is mounted on rubber isolators to further ensure the unit's quiet operation. All single-phase 13 SEER Champion Ultra heat pumps are backed by a standard 10-year limited warranty on the compressor and a five-year limited warranty on all other parts. Three-phase units come with a five-year compressor and one-year parts warranty.
