Ductless Systems

When a Ductless System Makes Sense

A ductless system is the right choice when you're adding a room or converting a space (garage, attic, basement) that has no existing ductwork, when one room in your house is always too hot or too cold despite your central system working fine, when you live in an older home with no ducts and don't want the cost and disruption of installing them, when you want zone control so different family members can set their own temperatures, or when you're supplementing an existing system that can't handle the load — common in homes with large additions or poor insulation on one side.

Ductless System Costs and Options

A single-zone ductless mini-split (one outdoor unit, one indoor unit) costs $2,500–$5,000 installed, depending on the BTU capacity and brand. Multi-zone systems with 2–5 indoor units connected to one outdoor compressor cost $5,000–$15,000. The most popular configuration in Southern Utah is a 2-zone system serving a master bedroom addition and a home office or converted garage — typically $5,000–$8,000 installed. We install Mitsubishi, Daikin, Carrier, and other leading brands.

Efficiency and Operating Cost

Ductless mini-splits are among the most efficient HVAC systems available, with SEER ratings of 20–33 compared to 14–18 for typical central AC units. They also eliminate duct losses — in a typical home, 20–30% of cooled air is lost through leaky or poorly insulated ducts. For Southern Utah homeowners paying high summer electricity bills, a ductless system in the rooms you use most can noticeably reduce monthly costs.
