Ductless Mini-Split Installation
for Orange County & Inland Empire
Cool and heat any room — without ductwork. Perfect for garages, room additions, ADUs, and spaces your central system can’t reach. Single-zone and multi-zone configurations with whisper-quiet inverter technology.
Common Spaces Where Mini-Splits Are the Best Solution
If your space doesn’t have ductwork — or your central system can’t keep it comfortable — a ductless mini-split is usually the smartest, most cost-effective answer.
Garages & Workshops
Turn your garage into a year-round workspace, gym, or hobby room. No ductwork needed — installs in one visit.
Room Additions & ADUs
New additions, granny flats, and ADUs often lack duct connections. A mini-split gives independent climate control without extending your central system.
Home Offices & Bonus Rooms
Converted spaces above the garage, sunrooms, and home offices often run hot or cold. A mini-split solves it with zone-specific control.
Hot & Cold Spots
That one room your central system can’t seem to reach? A mini-split handles it independently — no ductwork changes, no rebalancing.
Older Homes Without Ducts
Many older Orange County homes were built without central air. A multi-zone mini-split provides whole-home comfort without tearing into walls.
Server & Equipment Rooms
Dedicated cooling for server closets, wine rooms, or any space that needs precise, consistent temperature control year-round.
Simple System. Serious Comfort.
A ductless mini-split has two parts: a compact outdoor compressor and one or more indoor units mounted on your wall or ceiling. They connect through a small conduit — just a 3-inch hole in the wall. No ductwork. No major construction.
- Inverter technology adjusts compressor speed for precise comfort — no on/off cycling
- Both heating and cooling in one system (heat pump technology)
- Whisper-quiet operation — indoor units run as low as 19 dB
- Individual zone control — each room sets its own temperature
- SEER2 ratings of 18–30+ (vs. 14–16 for standard central AC)
- Avoids 25–30% energy loss from ductwork leaks

Mini-Split vs. Window Units vs. Extending Ductwork
Homeowners usually compare three options for spaces without ductwork. Here’s why mini-splits come out ahead for most situations.
- vs. Window units: Mini-splits are quieter, more efficient, more secure (no open window), and provide both heating and cooling
- vs. Extending ductwork: Running new ducts costs $3,000–$8,000+ in construction alone, requires tearing into walls/ceilings, and may not be possible in every home. A mini-split avoids all of that.
- vs. Portable AC: Portables are loud, inefficient, take up floor space, and require venting through a window. A mini-split is permanently mounted, quiet, and 2–3x more efficient.
- Energy savings: Mini-splits use 25–50% less energy than window or portable units for the same space
- Home value: A permanently installed mini-split adds value to your property; window and portable units don’t
Ductless Mini-Split FAQ
A single-zone system typically costs $3,500–$6,500 in Orange County. Multi-zone systems (2–5 indoor units) range from $7,000–$18,000+ depending on capacity and complexity. We provide free in-home estimates with upfront pricing and offer financing from $89/mo with approved credit.
A ductless mini-split has two parts: a compact outdoor compressor and one or more indoor air-handling units mounted on the wall or ceiling. They connect through a small conduit (refrigerant line, power, and drain) requiring only a 3-inch hole in the wall. Inverter technology adjusts compressor speed for precise temperature control and high energy efficiency.
Yes — that’s one of the most common uses. A single-zone mini-split can cool and heat your garage without any ductwork. The outdoor unit sits outside, the indoor unit mounts on the garage wall. Installation takes 4–6 hours with minimal disruption. Many Orange County homeowners use this for workshops, gyms, and home offices.
Significantly. Mini-splits avoid the 25–30% energy loss typical of ducted systems. Inverter-driven compressors adjust output to match exact demand rather than cycling on and off. Most modern mini-splits achieve SEER2 ratings of 18–30+, compared to 14–16 for standard central systems.
Yes. Most modern mini-splits are heat pumps — they cool in summer and heat in winter by reversing the refrigerant cycle. In Southern California’s mild climate, they operate at peak efficiency year-round. A mini-split can fully replace a space heater or wall furnace. Learn about Bosch heat pump systems for whole-home solutions.
Single-zone installs take 4–6 hours (one visit). Multi-zone with 2–3 indoor units typically takes one full day. Larger multi-zone projects (4–5 heads) may take two days. No major construction — just a small hole in the wall for the refrigerant line.
Yes. We pull all required permits and schedule inspections for every mini-split installation. Permit requirements vary by city — we handle the paperwork for Anaheim, Fullerton, Orange, Corona, and all other cities we serve. It’s included in our price.
Garages, room additions, ADUs, bonus rooms, home offices, sunrooms, server rooms, older homes without ductwork, and any area where extending your central system is impractical or expensive. They’re also great for solving hot/cold spots in specific rooms. Schedule a free estimate and we’ll assess your space.
