Systems 09LMAS1, 12LMAS1, 18LMAS1, 24LMAS1 - ENERGY STAR® Qualified

Best in class, feature packed, inverter heat pump system with new slim wall-mounted system and improved fan design. Compact outdoor unit and extended line set lengths add flexibility and simplifies the installation process. LMAS1 systems are Energy Star qualified heat pumps, meaning they save you money on your utility bill and provide both heating and cooling.

Inverter Technology

Through advanced technology, Inverter air conditioners are more economical to operate and quieter to run than conventional units. They are smoother and more stable in operation, and reach the desired temperature more quickly than conventional air conditioners. The Inverter component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor unit. Thus, the Inverter model can achieve 30% more operating efficiency than conventional models and therefore, is much less expensive to run.

ENERGY STAR® Qualified

Since mini splits have little to no ducting, they forego those energy losses typically associated central forced-air systems. Duct losses can easily account for more than 30% of energy consumption, especially if the ducts are not sealed tight or in an unconditioned space such as an attic or crawlspace. With ratings as high as 26.5-SEER (Seasonal Energy Efficiency Ratio), these systems are among the highest rated efficiency equipment available anywhere!

Clean Air

These heat pumps feature both an Apple-Catechin Filter and an Ion Deodorizing Filter. The Apple-Catechin Filter absorbs dust, mold spores and microorganisms by static electricity. Growth is inhibited and deactivated by the polyphenol ingredient extracted from apples. The Ion Deodorizing Filter deodorizes by powerfully decomposing absorbed odors using the oxidizing and reducing effects of ions generated by the ultra-fine particle ceramic.

Quiet Operation

Wall mounted systems include an extra quiet fan speed ("Quiet Mode") to make sure that you are not disturbed.

Wireless Remote Controller

Comfort control is at your fingertips with the standard wireless remote controller.

Washable Panel Filter

The removable and washable panel filter is an effective air cleanser, removing mold & dust from the environment. Cleaning of the indoor unit itself is simple due to the design and shape of the casing.

Smart System: Auto Mode

When the system is initially turned on, the fan speed is HIGH to reach the set temperature as quickly as possible. The fan speed will automatically adjust downward as the room begins to reach the set temperature.

Humidity Control

This system features Dry Mode, which helps to control humidity levels.

Other Standard Features Include:

Sleep Timer: Automatically adjusts the temperature while you sleep to make you more comfortable.
Sleep Timer
Auto Louver: Up/Down: Redirects airflow automatically with seven position up and down motion which can be set to auto swing.
Auto Louver
24 Hour Timer: Allows for one on/off cycle during a 24 hour period.
24 Hour Timer
Auto Restart/Reset: Following a power failure, systems will automatically restart in the same operating mode as before, once power has been restored.
Auto Restart/Reset
Auto restart: In the event of a temporary power failure, the air conditioner will automatically restart in the same operating mode as before, once the power supply is restored.
Auto Changeover
Cold Prevention: Indoor coil will warm prior to fan operating, preventing cold air during heating mode.
Cold Prevention
Low Ambient Cooling: Can operate in cooling mode even when outdoor ambient is 0°F, 14°F or 32°F, depending on model, without modification. Operation outside of factory specification is not recommended.
Low Ambient
Dry Mode: Allows for moisture removal in low load conditions of up to 50% of rated moisture removal capacity.
