Ductless Mini-Split Installation & Repair in Palm Beach, FL
A mini-split puts cooling exactly where you need it without tearing into walls or running new ductwork. They're the right answer for Florida rooms, garage conversions, older Palm Beach homes without adequate ductwork, and any space that a central system can't reach. We install, repair, and maintain all major brands across Palm Beach County.
Mini-splits have become one of the most practical cooling solutions in Palm Beach County — and for good reason.
A lot of Palm Beach's housing stock was built before central air conditioning was standard. Homes in El Cid, Flamingo Park, and the historic districts were designed without the duct chases that modern systems require. Retrofitting full ductwork into a 1940s or 1950s home is an expensive, disruptive project. A mini-split gives you efficient, zoned cooling without any of that.
The same logic applies to newer additions and conversions. A Florida room enclosed in the last few years. A garage converted into a home gym or workshop. A guest suite added over the garage. These spaces almost never have existing ductwork connections, and tapping into the central system often doesn't work well because the original system wasn't sized for the additional square footage.
Mini-splits solve all of these cleanly. The installation is minimally invasive — a small hole through the wall for the refrigerant and electrical lines, an indoor unit mounted on the wall or ceiling, and an outdoor compressor. Most single-zone installations are completed in less than a day.

These are the situations we see most often across Palm Beach County where a mini-split is a better solution than trying to extend a central system.
Florida Rooms & Enclosed Patios
This is the most common mini-split call we get in Palm Beach. A Florida room or enclosed lanai that was open before is now a conditioned space — but the central system was never sized for it. A single-zone mini-split handles it perfectly without touching the existing system.
Garage Conversions
Converting a garage into a gym, home office, workshop, or living space? There's almost never existing ductwork in a garage. A mini-split is the cleanest way to condition that space — installs in a day, no ductwork required.
Older Homes Without Adequate Ductwork
Many of Palm Beach's historic homes have ductwork that was added in pieces over the decades — undersized, poorly routed, or in bad condition. Rather than replacing all of it, a mini-split can handle specific problem rooms while the central system handles the rest of the house.
High-Rise Condos
Condo units on Palm Beach Island and along Flagler Drive often have building restrictions on modifying existing HVAC systems. A mini-split can add supplemental cooling to a master bedroom or living area without requiring building management approval for major ductwork changes.
Home Additions
Adding a new room, a guest suite, or an office addition? Extending the existing duct system to a new addition often doesn't work — the original system wasn't sized for additional square footage. A mini-split for the addition is cleaner and more efficient.
Rooms That Never Get Cool Enough
Some rooms in a home are always warmer than the rest — a master bedroom at the end of a long duct run, a room with a lot of west-facing windows, an upstairs bedroom in a two-story home. A mini-split in that room solves the problem without resizing the whole system.
How Ductless Mini-Splits Work
If you haven't had one before, here's the straightforward version.
A ductless mini-split system has two main components: an indoor air handler that mounts on the wall or ceiling inside the space you want to cool, and an outdoor compressor unit that sits outside. The two are connected by a small bundle of refrigerant lines and electrical cable that runs through a hole in the wall — typically about three inches wide.
The indoor unit pulls warm air from the room, passes it over a refrigerant coil that absorbs the heat, and blows the cooled air back into the space. The outdoor unit releases the heat outside. The process runs in reverse in heating mode — which is why mini-splits work as both air conditioners and heat pumps.
Single-zone vs multi-zone:
A single-zone system has one indoor unit connected to one outdoor compressor. It cools one room or space. This is the most common setup for Florida rooms, garage conversions, and problem rooms.
A multi-zone system connects multiple indoor units to one larger outdoor compressor. Each indoor unit has its own thermostat, so different rooms can be set to different temperatures independently. This works well for homes where multiple spaces need supplemental cooling, or for older homes where mini-splits are replacing an inadequate central system entirely.
Mini-Splits in Palm Beach — What's Different Here
A few things come up specifically in Palm Beach and Palm Beach County that aren't as common in other markets.
Historic home constraints
Homes in Palm Beach's historic districts — El Cid, Flamingo Park, Old Northwood — sometimes have restrictions on exterior modifications. Where the outdoor compressor unit goes, how the line set runs on the exterior, and what it looks like from the street can all matter. We're experienced working in these environments and know how to route installations cleanly and discreetly.
Salt air corrosion
Outdoor mini-split compressor units face the same salt air corrosion challenge as any other outdoor HVAC equipment in coastal Palm Beach. We recommend units with corrosion-resistant coatings for installations within a few miles of the Intracoastal or the ocean, and we apply additional coil protection at installation when it's warranted.
HOA and condo building rules
Many Palm Beach Island buildings and HOA communities have specific rules about where outdoor equipment can be placed and what it can look like. We're familiar with navigating these requirements and can help you understand what approvals you might need before we start.
Florida climate efficiency
Mini-splits are rated by SEER2 efficiency scores — the higher the number, the more efficient. In South Florida where a system runs nearly year-round, efficiency matters more than in markets with shorter cooling seasons. We install systems rated SEER2 18 and above for residential applications, which delivers meaningful savings on your FPL bill over the life of the system.
Mini-Split Brands We Install and Service
We install and service all major mini-split brands. The ones we work with most in Palm Beach County:
Each brand has different strengths — Mitsubishi and Daikin tend to lead on reliability and efficiency, LG and Samsung on value, Bosch on ultra-quiet operation. We'll match the right brand and model to your specific situation without steering you toward whatever has the best margin for us.
We also service and repair mini-splits installed by other contractors. If your existing unit isn't cooling properly, is making noise, or needs a refrigerant recharge, call us.
How a Mini-Split Installation Works
Free estimate and site assessment
We come to the space, measure it, assess wall and ceiling options for the indoor unit placement, identify the best location for the outdoor compressor, and plan the line set routing. We give you a written quote before anything starts.
Equipment selection
We recommend a system sized correctly for the space — not oversized, not undersized. We walk you through brand options and efficiency ratings so you can make an informed decision.
Installation day
We mount the indoor unit, place the outdoor compressor on a hurricane-rated pad, drill the line set penetration, run and connect the refrigerant lines and electrical cable, and seal everything properly. Most single-zone installations are complete in 4 to 6 hours.
Vacuum, charge, and startup
We pull a vacuum on the refrigerant lines to remove air and moisture, verify the charge, start the system, and test it through a full cooling cycle. We verify temperature differential at the indoor unit before we leave.
Walkthrough
We show you how to use the remote, set schedules if the unit has that feature, explain filter cleaning (mini-split filters need monthly rinsing), and walk through what regular maintenance looks like for your specific unit.
Mini-Split Repair and Maintenance in Palm Beach
Mini-splits need less maintenance than central systems, but they're not maintenance-free.
The most common mini-split issues we repair in Palm Beach:
Filter Clogs
The indoor unit filter needs to be cleaned monthly — more often in dusty environments. A clogged filter restricts airflow and makes the system work harder. This is something homeowners can do themselves, but many don't know it needs to be done that frequently.
Refrigerant Leaks
Refrigerant leaks do happen in mini-splits, usually at line set connections. Signs include the system running but not cooling as well as it used to, or ice forming on the indoor unit. We locate the leak, repair it, and recharge the system.
Drain Line Clogs
Drain line clogs affect mini-splits too, not just central systems. The indoor unit drains condensate through a line that needs to stay clear. In Palm Beach's humidity, this can become an issue. We flush it during maintenance visits.
Salt Air Corrosion
Outdoor compressor corrosion on the coil fins is a real concern in coastal Palm Beach. We clean the coil and apply protective coating during maintenance visits for units in high-exposure locations.
We recommend one professional service visit per year for mini-splits — plus monthly filter cleaning by the homeowner.
