Ductless mini splits installed in Jacksonville homes
Single and multi-zone heat pump heads for bonus rooms, garages, additions and older homes where ducts don't fit, sized per room and installed with clean line set routes.
Quick answer
When does a ductless mini split make sense in Jacksonville, FL?
A ductless mini split makes sense in Jacksonville when a room can't be reached by existing ducts, such as a bonus room, garage conversion or older plaster-walled home. ENERGY STAR certified mini splits also qualify for JEA's $200 rebate for residential electric customers.
Overview
Cooling a room without running a single duct
A mini split is a small heat pump. The outdoor unit connects to one or more wall, ceiling or floor heads through a refrigerant line set and a control cable, and each head has its own thermostat. There's no duct to leak into a hot attic, which is part of why they're so efficient here.
The work that decides whether a mini split feels good isn't the brand. It's sizing each head to its room, placing it where the air reaches the whole space without blowing on the bed, and routing the line set and condensate drain so they're neat outside and don't leak inside. A head that's too big for a small bedroom short-cycles and leaves the room damp, the same problem an oversized central system has.
Cost factors
What sets the price of a mini split install
- Number of headsEach additional zone adds a head, a line set run and labor.
- Head styleWall heads cost least; ceiling cassettes and floor consoles cost more to install.
- Line set length and routeLong runs, second floors and neat exterior covers add material and time.
- ElectricalA new dedicated circuit and disconnect are usually needed at the panel.
- Efficiency and rebateENERGY STAR certified systems qualify for JEA's $200 equipment rebate.
We price the install after measuring each room and the route for the line sets.
Options
Mini split or central air for the space
| Option | Best for | Watch out for |
|---|---|---|
| Single zone wall head | One problem room | Head placement and sizing |
| Multi-zone wall heads | Older homes with no duct path | Outdoor unit oversized for small rooms |
| Ceiling cassette | Rooms where wall space matters | Needs attic or ceiling access |
| Floor console | Sunrooms and rooms with low walls | Takes floor space |
| Extend central ducts | Rooms next to good trunk lines | Existing system capacity |
If the room sits next to a healthy trunk line and the system has capacity, extending the ducts can be the simpler choice.

What we fix
Single zone systems
One outdoor unit, one indoor head. This is the usual fix for a single problem room: the bonus room over the garage that runs five degrees warmer than the house, a sunroom, or a converted garage. We measure the room, account for windows and ceiling height, and pick the smallest capacity that carries the load. The head goes high on a wall with a clear throw across the room, and the line set runs in a paintable cover outside so it doesn't look like an afterthought.
Multi-zone systems
One outdoor unit can feed two to five heads, each with its own control. It suits older homes with no duct path and houses where different rooms need very different temperatures. The catch is sizing: the outdoor unit has a minimum turndown, so a big outdoor unit serving tiny bedrooms can cycle badly. We size each head first, then the outdoor unit, and sometimes recommend two smaller systems instead of one large one because it simply runs better. You'll see the per-room sizing on the quote.
Garages, workshops and bonus rooms
Garages and bonus rooms are the hardest spaces to cool here. They sit under hot roofs, often have little insulation, and in a garage the door lets the heat in every time it opens. Before sizing, we look at insulation and air leaks, because a head fighting an uninsulated ceiling will run constantly. In a garage workshop we'll often suggest a ceiling cassette or a floor console so the head isn't in the way of shelving or tools. Sealing the garage door edges helps too.

Ductless heads in Jacksonville's older homes
Older neighborhoods are where ductless earns its place. Many of the bungalows in Riverside were built long before central air, with plaster walls and little attic depth, so adding ducts means opening ceilings that owners would rather keep. A multi-zone system puts a head in each main room with only a small hole per head. Because the neighborhood sits in a local historic district, we plan the outdoor unit out of view from the street where we can.

FAQ
Mini split installation questions
Can a mini split heat as well as cool?
Yes, mini splits are heat pumps and handle Jacksonville's cold nights well.
Do mini splits qualify for the JEA rebate?
ENERGY STAR certified ductless systems earn JEA's $200 rebate for residential electric customers, and we file it.
How many heads can one outdoor unit run?
Usually two to five, depending on the model. Sizing each room matters more than maxing out the count.
Where does mini split condensate drain?
Each head has a condensate line sloped outside or to a small pump.
Will the head be noisy?
Indoor heads run very quietly on low speed, which is where they spend most of their time.
How long does a mini split install take?
A single zone is usually one day. Multi-zone systems can take two.
Which mini split brands do you install?
Mitsubishi Electric, Daikin, Carrier, Trane, Lennox and other major ductless lines.
