MS Mini-Splits

MS mini-splits are economical to install and provide cooling and heating with the convenience of a remote control. And best of all, turn the system off when you leave to save money on energy bills. These Mini-Splits offer additional heating and cooling without costly changes to your home's central cooling and heating system. Please see the product brochure for more information.

Special Features:

  • DC inverter: The DC Inverter uses the advanced 180º Sine Wave technology and combines this with a brushless DC motor compressor. This combination creates a more efficient system that reduces both sound and temperature fluctuations.
  • Twin Rotary Compressor: With double cams, this compressor has several features that increase its performance and reliability. The opposite double-blade design yields mechanical stability and less vibration that could cause stress on other components. An added benefit offered by the Twin Rotary compressor is its low noise level compared to conventional rotary compressors.

Impressive Features & Benefits: 

  • High-Efficiency Performance up to 20 SEER 
  • Chlorine-Free R-410A Refrigerant 
  • DC Inverter Technology Compressor 
  • Remote Control Indoor Antibacterial Fan 
  • Odor Capture Carbon Filter 
  • Easy-to-Read LCD Display 
  • Sleep Mode Setting (7 Hours Off-Cycle)
  • Easy-Clean Indoor Exterior Panels 
  • Auto-Restart Temperature Setting (Remote memory automatically set thermostat at last stored temperature setting.) 
  • Follow-Me Remote Control (Ambient temperature at location of remote control determines actual heating or cooling demand communication.) 
  • Turbo Settings for Fast Heating or Cooling 
  • Bi-Directional Airflow for Optimal Air Distribution

Goodman brand mini-splits use inverter compressor technology to maximize both performance and temperature control. An inverter allows the mini-split to continuously regulate the thermal transfer refrigerant flow by altering the speed of the compressor in response to the thermostat's demand for heating and cooling. This technology eliminates the all-on/all-off or stop-start cycles of some non-inverter compressors. Eliminating stop-start cycles helps to increase compressor efficiency to extend the life of compressor components, and to help reduce sharp fluctuations in the electrical load placed on a homes electrical power supply by an air conditioner or heat pump.

High-Efficiency Ductless Indoor Comfort

Goodman® brand mini-splits offer up to 20 SEER high-efficiency performance. "SEER" stands for Seasonal Energy Efficiency Ratio, a measure used by the U.S. Department of Energy to rate the efficiency of air conditioners and heat pumps. The higher the SEER, the greater the efficiency—and the lower the operating cost compared to a lower SEER, less-efficient unit.

Comfort. Savings. Performance. 

Goodman brand ductless mini-split air conditioning and heat pump systems are used where the installation of duct work is not practical. Mini-split systems work like typical central residential air conditioning or heat pump systems, just without the installation of sheet-metal duct work. The outdoor unit is connected to the indoor unit through a single 3½" opening in the wall. All the controls, refrigerant, and drain water run through the single opening, making installation easy. The indoor unit sits high on a wall and is operated by a remote control. Goodman brand mini-split systems are ideal for newly enclosed spaces (garages, porches, decks) that are not connected to the central air conditioning system. These units are also great for spot cooling of a sunny room or where a TV and sound system may heat up a space. These mini-splits combine cost-effective installation, excellent cooling and heating comfort, and the convenience of remote control. Best of all, they provide additional comfort without costly changes to your main air conditioning system.
