MHI Avanti 3.5kW Split System

Model DXK12ZSA-WF1

The 3.5kW MHI Avanti Split (model SRK35ZSA-W) is sized for large bedrooms and smaller living rooms. As a guide it suits a typical insulated room of roughly 23 to 28m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 5kW.
