Repair, installation and maintenance for ductless systems
What Is a Ductless Mini-Split?
A mini-split is a cooling and heating system that does not need air ducts. It has two main units joined by a small bundle of lines.
- OutsideOutdoor unit It sits on a pad or a wall bracket. It holds the compressor, which moves heat out of your home in summer.
- Through the wallLine set Copper refrigerant lines, a power wire and a drain line. They pass through one small hole in the wall.
- InsideIndoor unit It mounts high on the wall or in the ceiling. It blows cool or warm air right into the room and has its own remote.
Because the air goes straight into the room, there are no ducts in a hot attic for cool air to leak out of on the way.
Where Mini-Splits Fit in Valley Homes
Tap a space to learn why a mini-split works well there.
Casitas and guest houses
A casita often sits away from the main house, so running ducts out to it is hard. A mini-split gives it its own cooling and heating. You only run it when someone is staying there.
Room additions
Your main AC was sized for the house as it was first built. A new room can push it past what it can handle. A mini-split cools the new space without overloading the old system.
Garage conversions and workshops
Valley garages get very hot in summer. A mini-split can turn a garage into a home gym, office or workshop you can use all year.
The room that never cools
Many homes have one room that stays hot, like a west-facing bedroom or an upstairs bonus room. A mini-split in that room can fix the problem without changing the whole system.
Older homes without ducts
Some older homes in the Valley were built for evaporative coolers or have no ducts at all. Mini-splits add real air conditioning without tearing into ceilings for new duct work.
Sunrooms and Arizona rooms
Rooms with lots of glass heat up fast. A mini-split lets you cool that room on its own schedule.
One indoor unit can cool or heat a single room on its own.
Single-Zone or Multi-Zone?
A "zone" is a room or area with its own indoor unit and its own temperature setting.
One outdoor unit + one indoor unit. It cools and heats one room or one open area.
Good for:
- A casita or guest house
- A garage or workshop
- One hot bedroom
- A room addition
One outdoor unit + two or more indoor units. Each room gets its own unit and its own setting.
Good for:
- Several rooms that need help
- A home with no ducts
- A guest wing or upstairs
- People who like different temperatures

Mini-Split Installation
What an install with us includes:
- We look at the space and size the system for the room and the Arizona heat.
- We help you pick the best spot for each indoor unit.

Mini-Split Maintenance
Arizona dust clogs mini-split filters and coils fast. A dirty unit cools less, can drip water and may start to smell. A maintenance visit includes:
- Clean the filters
- Clean the indoor coil and blower wheel
- Clear and test the drain line
- Rinse the outdoor coil
- Check refrigerant and wiring
- Test cooling and heating
Want visits on a schedule? Our Home Care Plan includes two visits a year. Members also get up to an additional year of warranty on our work. See also heat pump maintenance.

Cool in Summer, Warm in Winter
Summer
The system pulls heat out of the room and sends it outside.
Winter
Most mini-splits are heat pumps. They run in reverse and bring heat into the room.
Valley winters are mild, which suits heat pump heating well. If your mini-split will not heat, see our heat pump repair and heat pump service pages, or book a visit.

Why Homeowners Choose Valley Services
Mini-Split Questions
How much does mini-split repair cost?
It depends on what is wrong. Our AC and HVAC diagnostic fee is $99. After your tech finds the cause, they explain the repair and its price so you can decide.
Why is my mini-split dripping water inside?
Most often the drain line or drain pan is clogged, or the coil is dirty or frozen. Turn the unit off and book a visit so the water does not damage your wall or floor.
Can a mini-split heat my home in winter?
Yes. Most mini-splits are heat pumps, so they heat as well as cool. Valley winters are mild, which suits them well.
Do I need a single-zone or multi-zone system?
One room or space usually needs a single-zone system. Several rooms usually need a multi-zone system or more than one single-zone system. We help you choose after we see the space.
How often should a mini-split be cleaned?
Rinse the filters about once a month when the unit runs a lot. Have a pro clean the coil, blower wheel and drain at least once a year. Our Home Care Plan includes two visits a year.
Have a central AC system instead? See our AC repair, AC installation and heat pump repair pages, or schedule an appointment online.
