Mini split installation involves setting up a ductless heating and cooling system that allows you to control temperatures in individual rooms or zones. These systems consist of an outdoor unit connected to one or more indoor units, providing efficient heating and cooling without the need for ductwork.
What Is Mini Split Installation?
Mini splits are one of the most flexible HVAC solutions, especially for homes without existing ductwork or spaces that need independent temperature control.
They are a strong option if you are:
- Living in an older home without ducts
- Adding an ADU, extension, or garage conversion
- Looking to control temperatures room by room
- Dealing with hot or cold spots in your home
- Wanting a more energy-efficient solution
Is a Mini Split System Right for Your Home?
Homes across the Bay Area vary widely, from older properties without ductwork to newer homes needing more precise temperature control.
Mini split systems are often used when:
• Adding living space (ADUs, conversions)
• Improving comfort in specific areas
• Avoiding major ductwork installation
• Solving uneven heating or cooling
We design systems based on how your home is actually used so each space stays comfortable and efficient.

Single-Zone vs Multi-Zone Mini Split Systems
Choosing the right system depends on how many areas you want to condition.
Single-Zone Systems
• One indoor unit connected to one outdoor unit
• Ideal for individual rooms or smaller spaces
Multi-Zone Systems
• Multiple indoor units connected to one outdoor unit
• Ideal for whole-home or multi-room applications
We help determine the right setup based on your layout and comfort goals.
Many mini split installations focus only on placing units in available spaces.
Our approach focuses on proper system design, including room sizing, unit placement, and overall system balance, so each zone performs efficiently and maintains consistent comfort.
Key factors include:
- Proper system sizing for each room
- Strategic indoor unit placement to ensure proper airflow and coverage
- Electrical capacity and proper system integration
- Overall system design and zoning balance
Incorrect installation can lead to:
- Uneven temperatures between rooms
- Poor airflow and comfort issues
- Short cycling or inefficient operation
- Reduced system lifespan
