What a mini-split in Florence has to handle
Your mini-split will run eleven months out of the year here, heating from October through April and cooling from June through September. Winter nights average 26°F across December, January and February, and summer afternoons average 85°F. That is a long stretch of work for one system, on both ends of the thermometer.
Any mini-split manufactured now has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Kentucky has also logged 14 winter storms and 86 damaging wind events over the last ten years, and 24% of households in the state went at least 24 hours without power in 2024. Worth asking about backup heat or a hybrid setup if losing power on a cold night is a real concern where you live.

Kentucky requires HVAC contractors to hold a state license.
Kentucky licenses HVAC contractors through the Department of Housing, Buildings and Construction, and that license means the state tested and recorded the contractor holding it. It covers the contractor, not this particular mini-split job, so the person or company doing the work should be the one who actually holds it.
For an installation like this, most cities and counties in Kentucky also require a permit from the local building office, with an inspection once the work is done. That inspection is a separate check on the finished job, apart from whatever the contractor's license already covers.

- Is a mini split worth it?
- For most homes here, yes, especially in a room that never had ductwork or a space an addition left out. Winters run cold, down to 26°F on average overnight from December through February, and a mini split with a heat pump handles that kind of cold while also covering the four months of summer heat. Because it needs heat or cooling nearly 11 months of the year, a system that does both jobs well earns its keep. A contractor can tell you whether one indoor unit covers your space or whether you need more than one.
- How many rooms can a mini split cover?
- A single indoor unit is built for one room or one open area, but a mini split system can run several indoor units off one outdoor unit, and each one gets its own thermostat. How many rooms that adds up to depends on the size of each room, the layout, and how much heating and cooling each space actually needs. A contractor sizes the system room by room rather than guessing at a number that fits every house.
- Can a mini split heat a whole house?
- It can, if enough indoor units are installed to cover every room and each one is sized for that space. A single indoor unit only heats the room it's in, so whole-house coverage means a multi-zone system, not one unit doing all the work. Given how cold nights get here, down to 26°F on average in the coldest months, the outdoor unit and each indoor unit need to be matched to the house's heating load, not just its square footage. A contractor can work out how many zones your house needs and where they go.
