We install a lot of ductless mini-split AC systems in Lake Nona. Probably three or four a week during peak season. Mostly garages, home additions, sunrooms, and home offices that were added after the original construction. But we also see a lot of homeowners who've been told a mini-split is the answer to problems that a mini-split won't actually solve. So let us give you the straight story.
What Is a Ductless Mini-Split System?
A ductless mini-split is an air conditioning system that doesn't need ductwork. It has two main parts: an outdoor compressor unit and an indoor wall-mounted air handler (the head unit). The two are connected by a small conduit — refrigerant lines, a drain line, and electrical — that runs through a small hole in the wall. No ductwork required.
They're called "mini-splits" because they split the system into two components. They're called "ductless" because — you guessed it — no ducts. Most mini-split installation in Lake Nona jobs take us about 4–6 hours start to finish.
When Does a Mini-Split Make Sense in Lake Nona?
Here are the situations where a ductless AC installation genuinely makes sense:
- Garage conversions or workshops — By far the most common reason we install mini-splits in Lake Nona. If you're finishing your garage or using it as a workshop, a mini-split is the right solution. Extending your home's ductwork to the garage is expensive and often impractical.
- Home additions — Adding a sunroom, in-law suite, or additional bedroom? If it's not connected to your existing duct system, a mini-split is clean and efficient.
- Home offices in converted spaces — Very common in Lake Nona's newer homes where people repurposed spaces like bonus rooms that weren't well-served by the original duct system.
- Rooms that are always too hot or too cold — If one room in your house is consistently uncomfortable despite the main system running fine, a mini-split gives you independent temperature control for that space.
- Homes without ductwork — Older homes or spaces being converted to living area with no existing ducts.

Mini-Split Installation Cost in Lake Nona (2025)
Single-Zone Mini-Split Installation
Multi-Zone Mini-Split Installation
The price depends on the BTU capacity (size of the unit), brand, and complexity of the installation. A 12,000 BTU single-zone unit for a standard garage in Eagle Creek or Laureate Park typically runs $1,800–$2,500 installed. A premium variable speed unit with WiFi control will be at the higher end.
We work with brands like Mitsubishi, Daikin, LG, and Carrier mini-split systems. We'll recommend the right brand and size for your space — not just the most expensive option.
Mini-Split vs. Extending Existing Ductwork
The most common question we get: "Is it better to add a mini-split or extend my existing ductwork to this new space?"
Honestly — it depends. If the new space is close to your air handler and your existing system has capacity, extending ductwork can work. But for garage conversions, extending ductwork almost never makes sense because:
- Garage-to-living-space conversions change how your entire system is balanced
- Garages often have insulation issues that a mini-split handles better than ducts
- The extension work can be expensive and messy
- A mini-split gives you independent control of the garage temp without affecting your main house
For home additions that are architecturally attached and well-insulated, extending ductwork sometimes works better. We'll assess your specific situation and give you an honest recommendation.
Mini-Split Repair in Lake Nona
We also do mini-split repair in Lake Nona. Common issues include refrigerant leaks (same as regular AC), error codes on the indoor unit, remote control problems, drain line clogs, and compressor issues. Most ductless AC repair is same-day. If your mini-split is showing an error code or not cooling, give us a call.
Mini-splits have filters in the indoor head unit that need cleaning every 4–6 weeks. You can do this yourself — just pop the cover and rinse the filter under water. Once a year, have a tech clean the coils and check the refrigerant charge. This keeps efficiency up and prevents the common issues we see in neglected mini-splits.
