Features
- Precision Temperature Control Technology
- This condenser is equipped with inverter technology and an electronic linear expansion valve. By adjusting compressor speed and refrigerant flow, the output of the unit can be matched to the zone for precise temperature control and improved efficiency.
- Advanced Filtration System
- The MSZ-GS unit combines a hybrid catechin deodorizing filter with an enzyme-based filter for managing allergens. The anti-allergy filter not only captures the offending particles, it also breaks them down, cleaning the air as it is conditioned.
- Optional Base Pan Heater
- MXZ-C outdoor condensers have an optional Base Pan Heater to prevent condensate from freezing and damaging the unit in frigid climates. Please see the Accessories tab for (PAC-646BH-E) Base Pan Heater.
- Econo Cool Mode
- By slowly adjusting the cooling set point and swinging the horizontal vanes, the MSZ-GS unit can improve the efficiency of cooling operations without compromising the comfort provided.
- Hot-Start
- Mitsubishi's hot-start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
- Multiple Vane Control Options
- Auto mode selects the best vane position based on operating mode, and the swing modes cycle through all positions for maximum coverage. When wide mode is activated, fan speed increases beyond the current setting.

- MSZ-GS12NA-U1: 1/4" x 3/8" Line Set

- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
- Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing.
- Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.
- Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
- Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris.

The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.
