Ductless Mini Splits
(Showing 24 of 64)Ductless Mini Splits
Ductless mini splits deliver efficient heating and cooling without traditional ductwork. They’re ideal for additions, garages, hot rooms, remodels, and whole-home zoning where duct constraints or comfort issues make central systems difficult.
Shop by system type (single-zone vs multi-zone), indoor unit style (wall mount, ceiling cassette, floor/console), or by outdoor condenser requirements. Correct sizing (BTU), line set routing, and electrical planning are critical for a clean install and long-term reliability.
- Single-zone systems for one space or area
- Multi-zone systems for whole-home zoning and multiple rooms
- Indoor unit styles: wall mount, cassette, console
- Outdoor condensers sized to match capacity and zone count
Selection checklist: BTU load per zone, number of zones, indoor style, max line length, elevation limits, voltage, and low-ambient heating needs. Confirm compatibility between outdoor condenser and selected indoor heads.
Pro tip: Don’t size by square footage alone—sun exposure, insulation, ceiling height, and usage change the load. Right-sizing improves humidity control and efficiency.
