What does it cost to add AC to a small Lemon Grove bungalow that only has a wall heater?
A single-zone or two-zone ductless mini-split heat pump for a 900 to 1,300 square foot bungalow typically runs $6,500 to $12,000 installed. That's the standard path here because central ducting can't fit into homes this size without major ceiling work, and the mini-split handles both heating and cooling from one outdoor unit.
