About Zone.
Making professional-grade HVAC accessible to homeowners everywhere.
Our mission
Zone was founded on a simple principle: homeowners deserve access to professional-quality heating and cooling solutions without the markup, complexity, or hassle of traditional HVAC contractors.
We specialize in DIY ductless mini-split systems that deliver the same performance as contractor-installed units—at a fraction of the cost. Our systems are designed for straightforward installation, backed by expert support, and engineered to last.
Engineered, manufactured & assembled by Zone
Based in Salt Lake City, Utah, Zone engineers and manufactures its own mini-split systems. We control the entire product development and manufacturing process to ensure quality and innovation.
Our engineering team designs everything from scratch—from high-efficiency compressors to proprietary pre-charged linesets. Every system is then assembled and tested at our facility at 4375 W 1980 S, Salt Lake City, UT 84104 before shipping.
All orders ship directly from this central location, ensuring consistent quality control and faster delivery times. Our hands-on approach means better quality control, faster problem-solving, and continuous improvement based on real customer feedback.
