What a mini-split here has to handle
Nelson County asks for heat or cooling every month of the year. Winter nights average 27°F from December through February, and summer afternoons run 86°F, so the system you put in has to hold up on both ends without a break between them.
A new mini-split has to meet the federal minimum for its type, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That's the floor, not a feature, and it applies whether you're replacing one unit or adding a new zone. Most homes here heat with electricity, so when the power goes out, the heat goes with it. This area has had 15 winter storms and 55 damaging wind events over the past ten years, and statewide, close to a quarter of households lost power for a day or more in 2024. That's worth factoring in when you decide where the unit goes and what backup, if any, it needs.

Kentucky requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this particular job. It means the state tested this contractor and keeps a record of them through the Department of Housing, Buildings and Construction, so if something goes wrong there is a name and a file behind it.
For a mini-split installation, that license is what stands behind the contractor's work in Kentucky. In most cities and counties here, the installation also needs a permit from the local building office, with an inspection once the work is done. That inspection is separate from the state license and checks the installation itself, not the contractor.

- Is a mini split worth it?
- For the right house, yes. A mini split heats and cools without ductwork, so it works well in additions, garages, or older homes where running ducts is not practical. Winters here run cold, with lows averaging 27°F from December through February, so the unit needs to be sized for that kind of night, not just the room's square footage. A contractor can tell you whether a mini split fits your house or whether your setup calls for something else.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Single-zone systems cover one room or open area. Multi-zone systems connect several indoor heads to one outdoor unit, each with its own thermostat, so different rooms can run at different temperatures. How many zones your house needs depends on the layout, and a contractor sizing the job will walk through that with you.
- Can a mini split heat a whole house?
- It can, if there are enough indoor units placed to reach every room and the system is sized for the coldest nights, not just an average day. Homes here need heat from October through April, seven months a year, so the equipment has to keep up when it's 27°F outside, not just in milder weather. A mini split with a lower heating rating might struggle on the coldest nights even if it handles most of the season fine. This is a sizing question a contractor needs to work out room by room before installation.
