Zephyrhills asks a mini-split to work all year
Cooling season here runs March through November, nine months of summer afternoons averaging 91°F. Winter is short, just December through February, and mild, with nights averaging 50°F. That leaves almost no month where a mini-split can sit idle, so the unit you install needs to hold up to near-constant runtime.
Any mini-split installed new has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With most homes here heating on electricity, the heating side matters too, even with winter as short as it is. Florida also sees its share of power loss, with over a third of households going at least a day without it in 2024, and this area has logged 32 damaging wind events over the past ten years. Worth asking how the system you choose handles a restart after the power drops.

Florida requires HVAC contractors to hold a state license.
The state's license is held by the Construction Industry Licensing Board, which tests the contractor and keeps a record of that license. It covers the company, not any single job, so the same license applies whether the work is a mini-split or a furnace.
For this install, that license is what stands behind the person doing the work. On top of it, a mini-split installation in most cities and counties needs a permit from the local building office, and an inspection once the unit is in. That inspection is separate from the state license and checks the work itself, not the paperwork behind it.

- Is a mini split worth it?
- For most homes here, yes. Zephyrhills needs cooling nine months of the year and heat the other three, so a system that does both well earns its place. A mini split runs on electricity, which is how 90.8% of homes here already heat, and it puts heat or cool air right where people are instead of pushing it through ducts that lose some along the way. If your ducts are old, damaged, or don't reach a room you use, a mini split solves that without any duct work at all.
- How many rooms can a mini split cover?
- One outdoor unit can run several indoor units, called heads, each one heating and cooling the room it's mounted in. You can run the heads at different settings at the same time, so a bedroom can sit cooler than a living room right next to it. A contractor sizes the system to the rooms you want covered and the heat gain in each one, since a bedroom and a sunroom don't need the same capacity.
- Can a mini split heat a whole house?
- It can, if it's sized and placed for the whole house rather than a room or two. A multi-zone system with enough outdoor capacity and a head in each main area heats the house the same way a furnace does, just without ducts. Winter nights here average 50°F, which is well within what a mini split heat pump handles without backup heat. The sizing has to account for every room you want warm, so this is a job for a contractor to calculate rather than guess at.
