Single-Zone Systems

Single-zone ductless mini split systems are designed to condition one room or area using one outdoor condenser paired to one indoor unit (wall mount, cassette, or console). They’re ideal for garages, additions, offices, bonus rooms, and spaces where ductwork is impractical.

Choose the right system by matching BTU capacity to the real load and confirming install needs: voltage, line set length, elevation limits, and drainage. Proper sizing improves comfort, dehumidification, and efficiency—while reducing short-cycling and callbacks.

• Single outdoor unit + single indoor head (true zoning)
• Popular sizes: 9k, 12k, 18k, 24k, 36k BTU
• Compare efficiency, voltage, and low-ambient heating capability
• Verify line set requirements and installation constraints

Selection checklist: room load (BTU), climate heating needs, indoor unit style, line set length, condensate drain routing, voltage/amperage, and warranty/compatibility requirements.

Pro tip: Oversizing is a common mistake. A slightly smaller, properly matched system usually runs longer, removes more humidity, and feels more comfortable.
