Product Summary

Engineered for premium comfort, the ASXC18 traditional air conditioning unit is powered by a long-lasting Copeland® scroll compressor with built-in overload protection. The HERS tested system complies with the latest energy efficiency standards for greater savings. It is also built to maximize indoor comfort, as system performance is constantly monitored, while internal components have been engineered to ensure quiet operation at any setting.

The ASXC18 is an example of Nexgen’s innovative engineering process and commitment to customers’ comfort and satisfaction. This HVAC unit is acoustically engineered to reduce operating sounds. Plus, it is rated at up to 19 SEER, thereby supporting efficient performance with low operating costs. Various features contribute to the unit’s advantages, including:

  • Two-Stage Scroll Compressor: Provides higher efficiency than single-stage compressors and can provide years of reliable operation and comfort.
  • Two-Speed ECM Fan Motor: An advanced fan design minimizes noise as air passes across the condensing coil, providing consistently quiet operation.
  • Smart Diagnostics: The Copeland® ComfortAlert™ on-board diagnostics system constantly monitors the A/C, finding trouble spots quickly and reducing system failures.

The ASXC18’s efficient cooling capacity is enabled by the use of R-410A refrigerant and five-millimeter, refrigeration-grade premium copper tubing. This tubing design and an aluminum fin condenser coil system contribute to optimal heat transfer. At the same time, the air conditioner is protected by a factory-installed inline filter drier, which prevents dirt and moisture from reaching the refrigerant system.

A heavy-duty steel enclosure features a sound control top. It also protects the system with louvered coil guards, a wire fan discharge grill, and durable powder-paint finish. The air conditioner is compatible with the latest home automation technologies, including Nest, which enables notifications and control via your smartphone, while providing a level of air purification and dehumidification that allows for customized comfort everywhere in the home.
