Johnson Controls’ Coleman LX Series packaged units are 29% more efficient, with a SEER 14 rating. The unit’s cabinet design improves installation and serviceability with a compact size, which fits most roof frames and slabs, and exact-match gas and electric hookups. Front and top access to the compressor, refrigeration controls and blower enhances serviceability, as does top access to the condenser fan and motor, and side access to the compressor, coil, heat exchanger and filters. The 2- to 5-ton capacity units are currently available in cooling with gas heat configuration.
