Three 13 SEER residential package units - URNA gas/electric package unit, UQNA package heat pump, and USNA package air conditioner - are available in 2- to 4-ton models. Features include high- and low-pressure control for refrigerant cycle control, low ambient control for operation at low outdoor temperatures, and standard louver coil protection. The blower section with slide-out blower is easily accessible. The units feature a system-matched MultiFlex® coil with low static pressure drop and excellent cooling capacities, said the manufacturer. The models contain Copeland Scroll compressors. Each model repels water from entering by using a one-piece top and access panels with weep holes that channel water runoff.
