Zone-by-zone heating and cooling — no ductwork required.
At a glance
Done once. Done right.
Not every space fits a central system. Garages, ADUs, room additions, and older homes without ductwork all need a different approach — one that heats and cools precisely where you need it, without tearing into walls or ceilings to run ducts.
Garage conversions turned into living space or home offices
ADUs and pool houses that need standalone comfort control
Upstairs bedrooms that never seem to cool evenly with central air
Room additions where extending existing ductwork isn't practical
What Is a Ductless Mini-Split?
A mini-split is a ductless heat pump — an outdoor compressor connected to one or more indoor units (wall-mounted or ceiling cassette) that heat and cool a specific zone independently. Using inverter compressor and variable-speed technology, it adjusts output continuously rather than switching on and off, which is part of why these systems run quieter and more efficiently than standard central air.
Where Mini-Splits Fit Best

Room additions where extending existing ductwork isn’t practical
Historic homes without ductwork at all
Single-Zone vs. Multi-Zone
Single-zone systems connect one outdoor unit to one indoor unit — ideal for a single room, garage, or ADU.
Multi-zone systems connect one outdoor unit to multiple indoor units, giving you independent zone-by-zone temperature control across several rooms from a single outdoor compressor.
Quiet, Efficient Operation
Mini-splits run significantly quieter than a standard central air handler, and the variable-speed compressor means they avoid the energy loss that comes with leaky ductwork running through an unconditioned attic — a real issue for traditional ducted systems that mini-splits sidestep entirely with zero duct loss.

Mini Splits for ADUs in Orange County
Accessory dwelling units (ADUs), garage conversions and room additions are common across Orange County, and they are often the hardest spaces to heat and cool from the main house. Extending existing ductwork can overload the main system, so a ductless mini split is usually the simplest way to give an ADU its own heating and cooling.
A separate system and thermostat for the ADU, so a tenant or family member controls their own comfort
No new ductwork through the attic or slab
Heating and cooling from one heat pump outdoor unit
Single-zone systems for studios; multi-zone systems for ADUs with a bedroom and living area
Planning an ADU? Electrical capacity, outdoor unit placement and line-set routing are easiest to solve before drywall goes up. Contact us during the design stage and we will size the system to the space. For whole-house options, see heat pump installation and thermostat and HVAC control upgrades.
