A mini-split here runs cooling all year
West Palm Beach doesn't give a mini-split a break. Summer afternoons average 91°F and winter nights only drop to 57°F, so the system is doing cooling work in every month of the year. There's no heating season here. The compressor doesn't get the rest it would somewhere with a real winter.
Any mini-split built from 2023 onward has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That's the federal minimum for split systems, and a mini-split counts as one even though it runs mostly for cooling here. Storms are part of the picture too. Palm Beach County has seen 95 damaging wind events over the past ten years, and last year over a third of Florida households lost power for at least a day. A mini-split comes back on by itself once power returns, but it's worth knowing that going in.

Florida requires HVAC contractors to hold a state license.
The license comes from the Construction Industry Licensing Board, and it belongs to the contractor, not to any single job. That means the state tested this contractor before handing out the license, and there is a record of who holds it. It does not mean an inspector signs off on your mini-split once it is in.
That part falls to the local building office. Installing a mini-split in most cities and counties here needs a permit before the work starts and an inspection once it is done, and that inspection is what checks the work itself, separate from whatever the state license already tells you about the contractor.

- Is a mini split worth it?
- For a West Palm Beach home, yes, since cooling runs here almost the entire year. A mini split cools only the rooms you use, so a room that sits empty most of the day is not paying to stay cold. It also gets installed without ductwork, which matters if the space you are adding it to, like a garage conversion or a new room, has no ducts running to it already.
- How many rooms can a mini split cover?
- That depends on how many indoor heads the outdoor unit is set up to run. Each indoor head handles one room or open area on its own thermostat, so you can cool a bedroom without running one down the hall. A contractor will size the system to the rooms you want covered and the layout of the house.
- Can a mini split heat a whole house?
- A mini split can heat a whole house if enough indoor heads are placed to reach every room, but in West Palm Beach that heating side rarely gets used. Homes here do not have a heating season, so the system spends its time on cooling instead. A contractor sizing the install will size it for the cooling load your house actually sees.
