  • Landmark units with the most popular features and configurations are stocked and ready for fast delivery or pickup at commercial depots across North America.
  • Reduce future service and maintenance costs with R-410A refrigerant that replaces the older R-22 refrigerant that is expected to increase in cost as supplies diminish.

Efficient Operation

  • Up to 13.0 SEER and up to 11.4 EER
  • G/E and E/E available in 2- to 6-tons, HP available in 2- to 5-tons.
  • Meet or exceed ASHRAE 90.1-2004 standards.
  • 3-phase units are ENERGY STAR® qualified.

Easy to Install and Maintain

  • Hinged Access Panels – factory option provides quick access to components and protect panels and roof from damage during servicing.
  • Full-Perimeter Base Rail (with Rigging Holes) – provides greater structural integrity, so the unit is easier to handle when rigging and transporting.
  • Isolated Compressor Compartment – allows performance check during normal compressor operation without disrupting airflow.
  • Fork Slots on Three Sides – easy to pick up and transport units from almost any angle.
  • Corrosion-Resistant Removable, Reversible Drain Pan – provides application flexibility, durability and improved serviceability.
  • Independent Motor Mount – allows for easy and efficient service access without removing the top panel.

High-Performance Components

  • Direct Spark Ignition – electronic ignition eliminates standing pilot and enhances efficiency.
