What Is A Mitsubishi Ductless Air Conditioner?
Mitsubishi Electric is a global leader in ductless mini split HVAC technology. Their ductless air conditioners, also called mini splits, consist of an outdoor compressor and one or more indoor air handling units connected by refrigerant lines. Unlike traditional systems, ductless units require no bulky ductwork and can heat or cool specific zones or rooms. Mitsubishi offers industry-leading features, such as inverter-driven compressors, multi-stage filtration, and whisper-quiet operation. These systems suit single rooms, new additions, or whole-house applications, especially where duct installation is difficult.
How Much Does A Mitsubishi Ductless Air Conditioner Cost?
The total cost of a Mitsubishi ductless system includes the price of the units and installation fees. The main factors influencing this cost are:
