Ductless Mini-Split Installation
DUCTLESS MINI-SPLIT INSTALLATION IN PASADENA, CA
A ductless mini-split connects each indoor head to its outdoor unit through a small line set that usually needs only a hole about 3 inches across, so rooms can gain heating and cooling without new ductwork cut through ceilings and walls. Performance Plumbing, Heating & Air Conditioning, Inc. provides ductless mini-split installation in Pasadena, CA and throughout the San Gabriel Valley for additions, converted garages, home offices, bedrooms, and homes without existing ducts. Backed by 40+ years in heating and cooling, we plan head placement carefully, route line sets neatly, and price every installation upfront before work begins. Most single-zone projects finish in a day.
COMFORT FOR THE ROOMS YOUR DUCTS NEVER REACHED.
Many homes have at least one room that never feels right: a sunny back bedroom, a garage conversion, an upstairs office, or an addition built long after the original system. Extending ductwork to those spaces is often impractical or ineffective. A ductless mini-split delivers heating and cooling directly to the room that needs it most.
Because each indoor head has its own controls, family members can set different temperatures in different rooms without compromise, and unused rooms can simply be switched off to save energy.
- Single-zone and multi-zone systems
- Careful indoor head placement

DUCTLESS MINI-SPLIT INSTALLATION
ROOM-BY-ROOM COMFORT FOR PASADENA HOMES OF EVERY AGE.
Pasadena's older bungalows and craftsman homes often have limited attic space or none at all, while newer additions frequently sit beyond the reach of existing ducts. Ductless systems solve both problems gracefully. We choose indoor head locations that spread air evenly across each room, avoid furniture and window conflicts, and keep the equipment as discreet as possible, so the finished installation respects your home's character while delivering quiet, efficient heating and cooling.
HILLSIDE WALLS, GARAGE CONVERSIONS, AND ADUS EACH NEED THEIR OWN LAYOUT.
Homes across the San Gabriel Valley include hillside houses with tricky exterior walls, garages converted to living spaces, and accessory dwelling units that need their own comfort control. Each setting affects where the outdoor unit can sit, how the line set travels, and where condensate drains. We walk the property with you, evaluate electrical capacity, and design a layout that looks clean inside and out while performing reliably.
LINE SETS ARE WHERE CAREFUL INSTALLERS SHOW THEIR WORK.
A mini-split can be excellent equipment and still perform poorly if the refrigerant lines are kinked, poorly flared, or left unprotected in the sun. Our 40+ years of heating and cooling installations taught us to treat those connections with extra care. We pressure test every joint, pull a deep vacuum, cover exterior lines neatly, and slope condensate drains properly. Ready to fix the room that never feels comfortable?
WHAT A DUCTLESS MINI-SPLIT DELIVERS.
Targeted Comfort
Each indoor head heats or cools its own space, so the hot back bedroom, chilly office, or converted garage finally matches the comfort of the rest of your home.
No Duct Losses
Conditioned air goes directly into the room rather than traveling through attic ducts, avoiding the leakage and heat gain that waste energy in traditional systems.
Individual Room Control
Every zone has its own settings, letting household members choose their preferred temperatures while unused rooms can be turned down to save electricity throughout the day.
Quiet Operation
Indoor heads run with a gentle hum and the outdoor compressor stays outside, making mini-splits well suited for bedrooms, nurseries, studios, and home offices. Sleep comes easier.
Efficient Heating And Cooling
Inverter-driven mini-split heat pumps adjust their speed continuously, using only the energy needed to hold temperature, which keeps operating costs low in both seasons. Bills stay predictable.
Minimal Disruption
Installation typically requires only a small wall opening per indoor head, so rooms stay intact and the project finishes without major construction, dust, or drywall repairs.
our services
OUR DUCTLESS MINI-SPLIT INSTALLATION WORK.
We install ductless systems for individual rooms, additions, and entire homes throughout Pasadena and the San Gabriel Valley, choosing configurations that fit each space and the household's comfort goals. Every layout is custom.
ONE ROOM
Single-Zone Mini-Split Installation
One outdoor unit paired with one indoor head is ideal for a single problem room, garage conversion, or addition. We size the system to the room's load and place the head for balanced airflow.
MULTIPLE ROOMS
Multi-Zone Mini-Split Systems
A single outdoor unit can serve several indoor heads, each with its own controls. We plan the zones, size each head to its room, and route line sets efficiently to the shared outdoor unit.
BACKYARD HOMES
ADU and Addition Comfort Systems
Accessory dwelling units and additions often need independent heating and cooling. We design ductless systems that serve those spaces efficiently, giving occupants full control without tying into the main house system.
HEAD STYLES
Wall, Ceiling, and Floor Unit Installation
Wall-mounted heads suit most rooms, while ceiling cassettes and floor consoles fit spaces with special layouts. We recommend the style that delivers the best airflow and appearance for each room.
CLEAN ROUTING
Line Set and Condensate Routing
We route refrigerant lines, control wiring, and condensate drains through the smallest practical opening, protecting exterior lines with covers and sloping drains correctly so water leaves the head reliably. Neatness counts.
POWER SETUP
Outdoor Unit Mounting and Electrical
Outdoor units sit on level pads or wall brackets with proper clearances for airflow and service. We connect dedicated electrical circuits and disconnects so the system runs safely from day one.

FAQ
FREQUENTLY ASKED QUESTIONS.
Ductless mini-splits work differently from central systems, and homeowners often have questions about placement, zones, efficiency, and appearance. These answers explain what to expect before choosing a ductless system.
How Many Rooms Can One Mini-Split Outdoor Unit Serve?
Single-zone units serve one room, while multi-zone outdoor units commonly support two to five indoor heads, depending on the model and capacity. The right choice depends on room sizes, heating and cooling loads, and refrigerant line lengths to each head.
Where Is The Best Place To Mount A Ductless Indoor Head?
Heads work best high on an exterior wall with clear airflow across the room, away from direct sunlight, heat sources, and obstructions. Placement also considers line set routing, condensate drainage, and how the unit looks within the room.
Can A Mini-Split Heat And Cool?
Most modern mini-splits are heat pumps, so they provide both heating and cooling from the same indoor head. In Pasadena's mild climate, they heat efficiently throughout the winter season while delivering strong cooling performance during the hottest summer months.
Are Ductless Mini-Splits Energy Efficient?
Very efficient, generally speaking. Inverter compressors adjust output continuously instead of cycling on and off, and delivering air directly into rooms avoids duct losses. Zoning also lets you condition occupied rooms without heating or cooling empty spaces unnecessarily.
How Long Does A Mini-Split Installation Take?
Many single-zone installations take 1 day, while multi-zone systems may require 2 or 3 days, depending on the number of heads, line set lengths, and electrical work. We share a realistic timeline during the estimate so you can plan.
Will A Ductless Indoor Unit Look Out Of Place?
Wall-mounted heads are compact and neutral in color, and careful placement keeps them unobtrusive. For rooms where appearance matters most, ceiling cassettes or floor consoles provide lower-profile alternatives that blend in far more naturally and discreetly with the surrounding decor.
Can You Add A Mini-Split To A Garage Conversion Or ADU?
Absolutely, and often. Performance Plumbing, Heating & Air Conditioning, Inc. installs ductless systems in garage conversions, additions, and accessory dwelling units throughout Pasadena, CA, giving those spaces independent heating and cooling without tying into the main home's existing ductwork at all.

HOW WE WORK
FROM PROBLEM ROOM TO COMFORTABLE SPACE, HERE IS HOW.
STEP 01
WE WALK THE SPACE
We visit each room you want to condition, noting sun exposure, windows, insulation, and how the space is used. That walkthrough shapes head placement and zone planning around your household's real needs. Nothing is assumed.
STEP 02
WE SIZE EACH ZONE
Load calculations determine the capacity each room needs. Sizing zones individually prevents oversized heads that short cycle and undersized ones that struggle, giving every room steady, efficient comfort. Each room gets its own number.
STEP 03
WE PLAN THE LAYOUT
We choose indoor head locations, outdoor unit placement, line set paths, and condensate routes, then review the plan with you. Seeing the layout first keeps installation day free of surprises. Your input shapes the final plan.
STEP 04
WE MOUNT THE EQUIPMENT
Indoor heads are mounted level on secure brackets, and the outdoor unit is set on a pad or wall bracket with proper clearances. Every opening is sealed carefully against air and water. Clean holes matter.
STEP 05
WE CONNECT AND TEST
Refrigerant lines are flared or brazed, pressure tested, and evacuated before charging. Electrical and control wiring connections are completed and checked, confirming everything is secure and ready for operation. This step is never rushed.
STEP 06
WE DEMONSTRATE CONTROLS
We start each zone, verify heating and cooling operation, and show you how to use the remote controls and clean the filters. You finish the day comfortable and confident using your new system.
