Mitsubishi Split Ductless AC systems are up to 40% more efficient than traditional HVAC systems.


How Energy Efficient Air Conditioning Systems Work
As a Hawaii's first Diamond Elite Contractor, AEI installs Mitsubishi Electric Cooling & Heating systems that reduce energy consumption through:
- Smart Inverter technology: Inverter-driven compressors automatically adjust to the changing conditions of each room in order to deliver ideal comfort and minimize energy usage.
- Zoning: Zoning capabilities allow you to heat or cool the rooms you use the most, even turn off or setback the temperature in rooms that are not in use.
- Ductless technology: Ducts alone can lead up to a 30% loss in energy consumption, ductless technology means quicker cooling or heating times and bigger energy savings.
