Miami Mini Split AC Installation installs ductless mini-split systems for homeowners across Greater Miami. We are licensed HVAC pros, so the whole job is ours: sizing the system to the space, mounting the indoor unit, setting the outdoor condenser, running the line set, pulling the permit, and handling the refrigerant to code. We install single-zone and multi-zone systems, and we repair and replace them too.
Mini-splits are a natural fit for how Miami is built. A lot of homes here have rooms with no ductwork, additions, garages, Florida rooms, and older houses, and our heat and humidity run nearly year round. A ductless system cools those spaces efficiently without the cost of adding ducts, as long as it is sized right and installed by someone who knows the refrigerant and the permit side. That is the part we handle.
A ductless mini-split is not a repair, it is a smarter way to cool specific spaces. These are the situations where it is the best option.
An addition, a converted garage, a Florida room, or a hot upstairs bedroom often sits beyond what the central system can reach or keep up with. A mini-split puts dedicated, right-sized cooling in that exact room without re-working the rest of the house.
Older Miami homes, additions, and detached spaces frequently have no ducts, and adding them is expensive and invasive. A ductless mini-split delivers central-style comfort without the ductwork, which is why it is the go-to when new ducts don't make sense.
Window and portable units are loud, block the window, drip, and struggle in Miami's heat and humidity. A mini-split is quieter, far more efficient, dehumidifies better, and frees the window. It is the permanent upgrade from getting by.
Cooling the whole house to keep one bedroom, office, or in-law suite comfortable wastes energy. A single mini-split, or a multi-zone system with a head in each room, lets you cool only the spaces you use, each at its own temperature, which keeps the bill down.
Ductless mini-split installation, repair, and replacement by licensed HVAC pros, sized right, permitted, and charged to spec.
Installation is the core of what we do. We install ductless mini-split systems of every brand, single-zone for one room and multi-zone for a whole home, in houses, condos, additions, garages, and Florida rooms across Miami. Because we are licensed HVAC pros, the full job is ours: the right-sized unit, the mount, the outdoor condenser, the line set, the electrical, the permit, and the refrigerant charge.
The part that makes a mini-split last fifteen years instead of struggling is the sizing and the install. We size the system to the actual room, not a guess, run the line set and condensate drain clean, and charge the refrigerant to spec. An oversized or badly charged unit short-cycles, runs up the bill, and wears out early, so we get it right the first time.
Every install starts with a free on-site visit to look at the space, where the unit and condenser will go, and your electrical. You get a straight recommendation and one written price before any work starts.
When a mini-split stops cooling, leaks, ices up, throws an error code, or the indoor unit won't respond, it is usually one of a few things: low or leaking refrigerant, a dirty coil or filter, a failed capacitor or control board, a clogged condensate drain, or a sensor fault. We diagnose which one it is instead of guessing.
Mini-splits are different from central AC, and a lot of general techs aren't comfortable with them, especially the refrigerant and the inverter boards. We work on them every day, so we actually find the problem and fix it, whether that's a refrigerant leak, a drain, a board, or the outdoor unit, and we tell you honestly when a repair makes sense versus a replacement.
When a mini-split is old, inefficient, or failing beyond a worthwhile repair, replacing it is usually cheaper over time than nursing it along. Newer systems are far more efficient, cool and dehumidify better, and come with a fresh warranty, which matters in Miami where the unit runs most of the year.
We pull the old system, reuse what still makes sense like the line set when it's in good shape, and install a properly sized new unit matched to the space. If the old one was undersized or badly placed, we fix that instead of repeating it. You get a straight answer on repair versus replace, not an automatic upsell.
Miami is close to the ideal market for ductless mini-splits, and it comes down to how the homes are built and how the climate runs. A few things about living here make ductless the smart choice more often than not.
Plenty of Miami homes, especially older ones, additions, and detached spaces, were never built with ducts, or the ducts don't reach every room. Retrofitting a full duct system is costly and tears up the house. A ductless mini-split brings modern cooling to those spaces without any of that.
Here the AC runs most of the calendar, so efficiency and reliability matter more than almost anywhere. Mini-splits are among the most efficient systems you can install, and their inverter compressors hold a steady temperature instead of blasting on and off, which saves money over a long Miami cooling season.
Miami's humidity is as much the problem as the heat. Mini-splits dehumidify as they cool, and because each unit is sized to its space, it pulls moisture steadily rather than in short bursts. That keeps rooms comfortable and helps hold off the mold and mustiness humidity brings.
Florida rooms, converted garages, in-law suites, home offices, and upstairs bedrooms all get used on their own schedule. A mini-split, or a multi-zone system, lets you cool exactly those rooms at their own temperature instead of running the whole-house system to keep one space comfortable.
None of this requires tearing into your home or adding ducts. It is the reason ductless keeps winning in Miami: the right amount of cooling, in the rooms that need it, installed clean and sized correctly. That is what we do.
A mini-split only runs efficiently if the install is done right. Here is how we do it.
Every job starts with a free on-site visit. We measure the room, factor in the sun, windows, and ceiling height, and size the system to the actual cooling load, not a rule of thumb. The right size is what keeps it efficient and comfortable instead of short-cycling.
We decide where the indoor head and outdoor condenser go for the best airflow and the cleanest line-set run, check the electrical, and pull the permit. Mini-split installs are permitted and inspected in Miami-Dade, and we handle that as part of the job.
We mount the indoor unit, set the condenser, run the line set and condensate drain in a clean cover, make the electrical connections, and vacuum and charge the refrigerant to the manufacturer's spec. The vacuum and charge are the steps cheap installs skip, and they're what make it last.
We run the system, confirm it cools and dehumidifies to spec, check for leaks, and handle the inspection. Then we show you how the remote and modes work and leave the space clean. You end with a quiet, efficient system that works the first time.
A mini-split involves refrigerant, electrical, and precise sizing, not a job for a handyman. Every install is done by licensed, insured HVAC pros who handle the refrigerant to EPA standards, pull the permit, and get it inspected, so it is safe, efficient, and to code.
Half of what makes a mini-split work is getting the size right. We measure the actual cooling load instead of rounding up, so your system holds temperature and humidity efficiently instead of short-cycling, running up the bill, and wearing out early.
The difference between an install that lasts and one that fails is in the details: pulling a proper vacuum, charging the refrigerant to spec, and running a clean line set. We do those every time, which is exactly what the cheapest installs cut.
You get a free on-site estimate and one written price before we start. No hourly meter, no surprise at the end, and no charge to come size it up.
Most mini-split installers won't post a number. We will. A single-zone system for one room is the low end, and a multi-zone system with a head in several rooms is the high end, priced by the number of zones. Your exact price depends on the system, the number of rooms, and the electrical, so every job gets a free on-site quote first.
One indoor unit and one outdoor condenser for a single room or space, installed, permitted, and charged.
Several indoor heads on one or more condensers for multiple rooms or a whole home, priced by the number of zones.
Most repairs: a sensor, a drain, a capacitor, a cleaning. Major parts like a compressor or refrigerant leak run higher.
What moves the price: the number of zones and indoor heads, the system's BTU size and efficiency, how far the line set runs, any electrical or panel work, and the brand of equipment you choose.
These are typical ranges for planning, not a quote. Every home and every system is different, so we price yours at a free on-site visit before any work begins.
Straight answers to what we hear most during free mini-split estimates around Miami.
A single-zone mini-split for one room usually runs about $2,000 to $5,500 installed. A multi-zone system for several rooms or a whole home is priced by the number of zones and more often lands between $6,000 and $15,000 or more. The exact number depends on the system, how many rooms, and any electrical work, so every job gets a free on-site quote first.
Yes. A mini-split install adds refrigerant lines and electrical, so it requires a mechanical permit and an inspection in Miami-Dade. We pull the permit and handle the inspection as part of the job. Permitted work keeps the install safe, keeps your homeowners insurance valid, and is on record when you sell the home.
No, and it is not a good idea. A mini-split uses refrigerant that by law must be handled by an EPA-certified technician, plus electrical work and precise sizing and charging. An unpermitted handyman install often means an undersized or undercharged system that runs poorly, voids the warranty, and fails early. It needs a licensed HVAC pro.
A single-zone system is one indoor unit paired with one outdoor condenser, for cooling a single room or space. A multi-zone system runs several indoor heads off one or more condensers, so you can cool multiple rooms, each at its own temperature. Single-zone is the common fix for one hot room; multi-zone is for a whole home or several spaces.
A single-zone install is usually done in a day, often a few hours. A multi-zone system with several indoor heads, or a job that needs electrical work, takes longer, and we tell you what to expect when we quote it. We schedule it to be done in as few trips as possible.
Yes. Almost all mini-splits are heat pumps, so they heat as well as cool. In Miami that matters far less than the cooling, but on the rare cold snap the same system warms the room without a separate heater, and it does it efficiently.
A well-installed, well-maintained mini-split typically lasts about fifteen to twenty years. The install is a big part of that: correct sizing, a proper refrigerant charge, and a clean line set. In Miami, where it runs most of the year, keeping the filters and coils clean is what gets you the full life.
Yes. Every job starts with a free on-site visit where we look at the space, size the system to the room, check your electrical, and give you one written price before any work begins. There is no charge and no obligation.
We install, repair, and replace ductless mini-splits for homeowners across Miami-Dade and the South Florida coast, from Homestead in the south up through Miami and Fort Lauderdale to Boca Raton.
