This model is extremely quiet! With indoor units that operate as low as 24dBA meaning they are literally silent. Our outdoor units operate as low as 52 dBA, or the sound of normal conversation.


In addition to saving energy, the variable speed fan always keeps temperature fluctuations to an absolute minimum, allowing constant comfort in any room of your home, 365 days a year!


This system comes with a 7-year limited warranty on the compressor and a 5-year limited warranty on covered components.


  • LED Display - Unit Mounted. The LED displays the operating status of the unit and maintenance and service codes. Very useful for after-sales service!
  • Three-speed fan - The fan operates at three speeds: low, medium and high.
  • Air Filter - Cleanable air filter is supplied as standard.
  • Preheat Function - Delays fan operation until the indoor coil has reached a predetermined temperature that prevents cold air discharge while the system is operating in "heat" mode.
  • Auto Restart - Automatically restores the previous function setting in the event of a power outage.
  • Cooling Override - The button on the indoor unit allows a temporary 30-minute override of the system for forced "AUTO" or "COOL" operation.
  • Flare Fittings - Equipped with liquid and gas flare fittings for quick and secure piping.
  • Multi-Refrigerant Outlet - Allows left, right or rear access for refrigeration line connection.
