The Garage That Became the Hottest Room in the House
We get calls about this specific situation more than you’d think. Someone in Central Florida converts their garage into a home gym, a workshop, or a playroom for the kids. They figure the central system will handle it. Then July hits.
The converted space bakes. It’s 91 degrees outside and somehow feels hotter inside. The rest of the house is fine, but that one room is unusable from about 10 a.m. to 8 p.m.
A ductless mini split is almost always the right answer here. And honestly, it’s the right answer in a lot more situations than most homeowners realize.
Let’s talk about what ductless mini split AC in Central Florida actually looks like in practice, because there’s a lot of vague information out there and not enough real-world context.
How a Ductless System Actually Works
A mini split system has two main components: an outdoor condenser unit and one or more indoor air handlers. They connect through a small conduit, typically about three inches wide, that runs through the wall. No ductwork required. That’s the defining feature.
The indoor unit mounts high on the wall and delivers conditioned air directly into the space. You control it with a remote or, on most modern systems, through a smartphone app. Each indoor unit is its own zone, meaning you can set different temperatures in different rooms without affecting the rest of the house.
The U.S. Department of Energy notes that duct losses account for more than 30% of energy consumption in a typical central air system. Mini splits eliminate that entirely.
In a state like Florida, where cooling accounts for a disproportionate share of the electric bill, that efficiency difference is meaningful.
When a Mini Split Makes More Sense Than Central Air
Not every situation calls for a full central system replacement. Here are the scenarios where a ductless mini split wins outright.
Room additions. If you’ve added a sunroom, in-law suite, or bonus room to your home, extending ductwork to reach it is expensive and often disruptive. A mini split handles that space independently without touching your existing system.
Older homes without ductwork. Central Florida has no shortage of older concrete block homes, particularly in areas like Mount Dora and the broader Lake County corridor, that were built without ducted central air. Running ductwork through them is a major project. A ductless system solves the cooling problem without tearing walls apart.
Spaces with comfort complaints. Some rooms in a house are perpetually warmer or cooler than the rest. It’s usually a duct design or insulation issue. A mini split in the problem room eliminates the argument over the thermostat.
Light commercial spaces. We install ductless systems in small offices, workshops, and retail spaces regularly. If you’re running a small business out of a space that wasn’t designed for modern occupancy loads, a mini split gives you targeted control without a major infrastructure investment.

The Installation Process: What to Expect
One of the things homeowners are often surprised by is how quick a mini split install actually is. For a single-zone system, most jobs are done in a day. Sometimes less.
Here’s what happens: we mount the indoor air handler on the wall at the appropriate height and location. We drill a small hole through the exterior wall for the conduit, which carries the refrigerant lines, electrical wiring, and condensate drain line. The outdoor unit goes on a pad or bracket near the home’s exterior. We connect everything, test the system, and walk you through operation.
Clean, minimal, and surprisingly low-impact for what you get out of it.
Multi-zone systems, where one outdoor unit serves two or three indoor handlers in different rooms, take longer and involve more planning. But even those are typically a one to two day project.
Efficiency and Cost: The Real Numbers
Ductless mini splits are among the most efficient cooling options available. Most modern units carry SEER2 ratings well above the minimum federal standard. Some high-efficiency models hit SEER2 ratings in the mid-20s, which is exceptional by any measure.
ENERGY STAR certified mini splits are available across multiple brands and price points. We can help you find the right balance between upfront cost and long-term operating efficiency.
Speaking of cost: a single-zone mini split installation in Central Florida typically runs between $2,500 and $5,000 depending on the unit’s capacity, brand, and the complexity of the install. Multi-zone systems are higher. These are real numbers based on what we see in the field, not a marketing estimate.
And like our central system installs, qualifying mini split installations are covered under our 12-year parts, labor, and refrigerant warranty. That’s a level of coverage you won’t find from most contractors.
One Thing Worth Knowing About Florida Humidity
Here’s something that doesn’t get talked about enough. Mini splits don’t just cool the air. They dehumidify it. In Central Florida, where summer humidity regularly sits above 80%, that matters as much as the temperature.
A properly sized and installed mini split will make a space feel comfortable at a higher thermostat setting than a poorly sized central system. Comfort in Florida is about moisture removal, not just temperature. It’s something we think about on every install we do.
Thinking About a Ductless Mini Split for Your Home
If you’ve got a space that your central system can’t reach, a room that never gets comfortable, or you’re looking for a high-efficiency option for a new addition or conversion, a ductless mini split AC in Central Florida is absolutely worth a conversation.
