Step 1 of 3: Equipment

What kind of equipment?*

In Naples, your mini-split works cooling duty all year

Summer afternoons here average 92°F, and the compressor runs into that heat every month of the year. Winter nights average 56°F, so the heat pump side has little real work to do here. A new system spends its life cooling, not switching between seasons.

Any mini-split installed now has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With cooling the year-round job in Collier County, that SEER2 number is the one doing the work.

Florida saw 30 damaging wind events over the last ten years, and in 2024, 38% of households in the state lost power for at least 24 hours. Where the outdoor unit sits and how well it is mounted matters as much as the equipment itself.

Florida requires HVAC contractors to hold a state license.

The Construction Industry Licensing Board tests and keeps a record of that contractor, not of each separate job. So the license tells you the state has checked this contractor's qualifications, but it does not follow them onto your property for this particular installation.

The part that does follow the job is the permit. Installing a mini-split in most cities and counties in Florida needs a permit from the local building office, and an inspection once the work is done. That inspection is what checks the installation itself, the wiring, the mounting, the line set, separate from whatever the state already knows about the contractor's license.

Is a mini split worth it?: For Naples, yes. Cooling is the year-round job here, not something that shuts off for part of the year, and a mini split handles that while also covering the mild winter nights without needing a separate heating system. It also means one room or zone can run without conditioning the whole house, which matters when the system is working most days of the year anyway.
How many rooms can a mini split cover?: A single-zone system heats and cools one room or open area. Multi-zone systems connect several indoor units to one outdoor condenser, so a home needing coverage in several rooms can run them all off a single outdoor unit. A contractor sizing the system will look at the square footage and layout of each room before deciding how many zones the house needs.
Can a mini split heat a whole house?: A multi-zone mini split can heat a whole house if enough indoor units are placed to cover every room, since each zone works as its own heat pump. Naples rarely tests that side of the system hard, with winter lows averaging 56°F, so the heating capacity that matters more here is being able to take the edge off a cool night rather than carry a home through a real winter. Whether the layout of a specific house works for whole-home coverage is something a contractor needs to walk through in person.
