Ductless Mini-Split Installation | Tampa Bay

Extending an existing duct system to reach a converted garage, a sunroom or a detached office is often impractical. Runs get long, the existing equipment may not have the capacity, and the ducts would have to cross attic space or exterior walls. A mini-split sidesteps all of it by putting the air handler in the room itself.

Because there is no ductwork, there is no duct loss. A mini-split delivers its rated capacity to the room, which is why it frequently outperforms a central system serving the same space through a long attic duct run.

Where mini-splits make sense

Additions and converted garages that were never connected to the central system. Sunrooms and enclosed lanais with no duct route. Detached workshops, studios and offices. Homes with no existing ductwork at all. And rooms that a central system simply cannot keep comfortable because of their position at the end of a long run. In each case the alternative is either an impractical duct extension or no conditioning at all.

Single zone versus multi-zone

A single-zone system serves one room from one outdoor unit, which is the simplest and most efficient arrangement. A multi-zone system connects several indoor heads to one outdoor unit, which suits a whole-house installation or several rooms being conditioned together. Multi-zone systems are more complex, and because the outdoor unit modulates across the connected heads, they need to be sized and configured carefully to perform well.

Installation details that decide performance

The indoor head needs to be positioned so it does not blow directly onto where people sit or sleep, and high on a wall is usually right for cooling. The condensate has to drain somewhere, which takes planning if gravity is not available. The line set run between indoor and outdoor units has a maximum length and elevation change, and exceeding either degrades capacity. None of those are afterthoughts.

When to call

You have an addition with no ductwork
A garage or outbuilding is being converted to living space
One room is never comfortable on the central system
You have a sunroom or enclosed lanai to condition
You want a detached office or studio cooled
Extending existing ducts is impractical or impossible

How the work is handled

Calculate the load for the space being conditioned
Agree indoor head positions and the line set route
Confirm power supply and condensate drainage path
Install indoor and outdoor units, line set and drain
Commission, verify charge and confirm operation in both modes

What affects the cost

We do not quote a number before seeing the property, because the same job on two similar houses can need different work. These are the factors that move the scope:

Number of zones and whether single or multi-zone
Capacity required by the calculated load of the space
Line set length and the route between indoor and outdoor
Electrical work if a new circuit is needed
Condensate drainage provisions, including a pump if required
Mounting arrangements for wall, ceiling or floor positions

Frequently asked questions

Is a mini-split as good as central air?

For the room it serves, often better, because there is no duct loss. Its limitation is coverage: it conditions the space it is in rather than the whole house, so it suits a single room or a set of zones rather than replacing a central system unless zoned throughout.

Can one mini-split cool several rooms?

A multi-zone system connects several indoor heads to one outdoor unit and can. It is more complex to size and configure than a single zone, and because the outdoor unit modulates across the heads, the setup has to be done carefully to perform well.

Do mini-splits cost more to run?

Usually less for the space they serve, since there are no ducts to lose capacity through and the inverter compressor modulates rather than running at full output or off. Efficiency claims are best judged against the actual room load rather than a headline rating.

Where does the condensate go?

It drains by gravity where a route exists, or through a small condensate pump where it does not. Planning it at design stage matters, because retrofitting a drain path after the line set is installed is far more difficult.
