Johnson Controls has expanded its York LX and Latitude Series of mid-efficiency air conditioners and heat pumps with the addition of 14.5-SEER condensing units. The new 1.5-ton models feature the same footprint and height as the 2-ton models in the series. When used with York’s variable-speed indoor products, the air conditioners can achieve efficiency levels that qualify them for the Energy Star designation and a federal tax credit. Both models use environmentally friendly R-410A refrigerant and a coil constructed of aluminum MicroChannel tubing and enhanced aluminum fins for increased efficiency and corrosion protection, said officials. The coils are further protected from damage by a polymer mesh applied between the coil face and a coated steel coil guard, while high-pressure relief valves and temperature sensors protect the compressors in the two units. Upward airflow carries the normal operating noise of the models away from the living area and a rigid top panel reduces any motor sound in the units. In addition, Johnson Controls said the isolated compressor mounts minimize compressor-operating sounds and, in the case of the LX model, a louvered steel coil guard, swept-wing fan blade and compressor blanket ensure quiet operation.
