A ductless mini-split system is a very efficient way to heat and cool your home. It allows you to control the temperature in each room without needing new ductwork. At GoTech Air Conditioning & Heating, we create and set up ductless HVAC systems. We serve homes, ADUs, garages, offices, and remodels in Southern California. We create custom solutions for your needs. We can help you with a single-zone or multi-zone setup. Our focus is on comfort, efficiency, and a clean installation.
A mini-split, also known as a ductless split system, uses a small outdoor heat pump. This pump connects to one or more indoor units. These indoor units can be wall-mounted, floor-mounted, or ceiling cassette style depending on your layout.
Each zone runs independently, letting you heat or cool specific rooms while shutting off the ones you’re not using. Without ductwork, you avoid duct losses. These losses are often around 20–30% in older homes. This means you get more efficient and direct comfort.
Modern systems use inverter compressors and variable-speed fans. This allows for smoother and quieter operation than traditional systems, which constantly start and stop.
You choose which rooms to condition—bedrooms, offices, garages, ADUs, or the whole home.
Because mini-splits don’t rely on ducts, they deliver strong efficiency even in retrofit installations.
Indoor heads operate quietly, making them perfect for bedrooms and offices.
Choose wall units, floor consoles, or mini-split ceiling cassette units for clean airflow distribution.
Most mini-splits operate as heat pumps, providing year-round comfort without needing a separate furnace.
With no ducts circulating dust, indoor units use washable filters for cleaner airflow.
Best for conditioning a single room, garage conversion, or addition.
One outdoor unit supports several indoor units—ideal for full-home zoning.
Compact, quiet, and mounted in the ceiling for a clean, minimalist look.
A combination of ductless heads and small duct runs for unique layouts or partial renovations.
If you are choosing between mini-splits, VRF/VRV, or central ducted HVAC, we can help. We will compare their performance, efficiency, and long-term costs.
We focus on proper design, correct sizing, and clean workmanship. Every installation follows a detailed workflow:
We measure room size, check insulation, window load, and determine the correct BTU rating for each zone.
We discuss head placement, concealment options, line-set routing, drain paths, and wiring.
We handle the permit process, electrical requirements, and alignment with manufacturer and code standards.
We use secure brackets, pads, or wall mounts and route refrigerant lines carefully for a neat appearance.
We perform vacuum pulls, pressure tests, leak checks, and electrical connections to manufacturer spec.
We check airflow, temperature split, refrigerant operation, sound levels, and remote or controller function.
We show you how to use the system, adjust modes, clean filters, and keep your ductless HVAC running efficiently.
Typical price ranges vary based on design, efficiency, system size, and installation complexity:
Single-zone installation: ~$4,000 – $8,500
Multi-zone installation (2–5 zones): ~$8,500 – $18,000+
Ceiling cassette or long line-sets: typically above the mid-range
The final price depends on:
Number of indoor heads and BTU sizes
SEER2/HSPF2 efficiency ratings
Line-set length and concealment options
Electrical panel capacity
Second-story or difficult routing
Permit requirements
Many ductless HVAC systems qualify for rebates, especially ENERGY STAR® certified models. We can check available programs and provide documentation.
Mini-splits are ideal for:
Homes without ductwork
Additions, offices, ADUs, or bonus rooms
Spaces that stay too hot or cold
Homes needing room-by-room zoning
Central HVAC works best if you have good ductwork. It allows you to control the temperature in your whole home from one thermostat. Many homeowners choose a hybrid approach—central air for main areas plus ductless for specific rooms.
