Johnson-Controls-05142012-body.pngJohnson Controls expands its Coleman® line of 14.5 SEER LX  and Comforteer air conditioners with 1.5-ton models.

Johnson Controls, the global leader in building efficiency, has added 1.5-ton condensing units to the Coleman® LX and Comforteer series of mid-efficiency 14.5 SEER (seasonal energy efficiency rating) air conditioners and heat pumps.

To boost energy efficiency and offer a compact footprint, both new 1.5-ton models include a coil constructed of aluminum MicroChannel tubing and enhanced aluminum fins. The coils are protected from damage by a sturdy polymer mesh applied between the coil face and a coated steel guard.

Streamlined power and control wiring connections allow for decreased installation time and costs. The units simplify access and maintenance with fully exposed refrigerant connections and a single electrical panel that covers the electrical controls.

Other features include:

  • Compressors protected against high temperature and pressure
  • Isolated compressor mounts to help reduce operating noise
  • Permanently lubricated motor bearings requiring no annual maintenance
  • A compressor sound blanket and swept-wing fan blade for low sound on LX models

SEER ratings meet the ENERGY STAR® level of 14.5 SEER with a standard PSC (permanent split capacitor) indoor section, and meet or exceed federal tax credit level of 16 SEER when matched with single- or variable-speed ECM (electronically commutated motor) indoor sections.
