What you pay to have a ductless mini-split climate control system installed in your Sandy Valley home will depend on several factors, including the size and number of indoor units you need, the brand and model you've selected, and how straightforward or complicated the installation is. Even more, your home or building's specific circumstances could make the system either a good or bad fit for what you need. When all's said and done, unless you're going with a portable or window option, you're looking at anywhere from $3,000 to $8,000 for a single-zone system. If you require a multi-zone setup, which could cover a much larger area, the number I've seen most often in estimates goes from $7,000 to $15,000.
