What a mini-split here has to handle
Bowling Green needs heat or cooling every month of the year. Winter nights average 29°F from December through February, and summer afternoons run near 88°F. That is a mini-split working October through April to keep the house warm, then May through September to keep it cool, with barely a break between.
A unit built on or after January 1, 2023 has to meet the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. A mini-split installed here counts as that kind of system, so those numbers are the floor, not a feature. On the coldest nights, 56.5% of homes in the area are running on electric heat, which means the heat pump side of the system is doing the work directly, not just helping a furnace along. The area has also logged 11 winter storms and 98 damaging wind events over the past ten years, and in 2024, 24% of Kentucky households went at least a day without power. Worth thinking about when deciding where the outdoor unit sits and what it's wired to.

Kentucky requires HVAC contractors to hold a state license.
Kentucky issues this license through the Department of Housing, Buildings and Construction. The state tested the contractor and keeps that business on file, but the license is issued once, to the company, not to each crew that shows up or each job it takes on.
For a mini-split, that license covers who is allowed to take the job. In most cities and counties, the installation itself still needs a permit from the local building office, and an inspection once the work is done. That permit and inspection, where they apply, check the actual work at your house, separate from whether the contractor is licensed to be there.

- Is a mini split worth it?
- For the right house, yes. A mini split heats and cools without ductwork, so it works well in a room addition, a garage conversion, or a house that never had central air. It runs on electricity, so it fits into a home already wired for electric heat. A contractor can look at the house and say whether it makes more sense than extending existing ductwork or adding to a system already in place.
- How many rooms can a mini split cover?
- One outdoor unit can run one indoor head or several, depending on the system. A single-zone system heats and cools one room or open area. A multi-zone system connects one outdoor unit to multiple indoor heads, each with its own thermostat, so several rooms can be covered and controlled separately. How many zones an outdoor unit can carry depends on its size, and a contractor will size that against the square footage and layout of the house.
- Can a mini split heat a whole house?
- It can, if enough zones are placed to reach every room. A multi-zone mini split heats a whole house the same way a central system does, just without ducts, with each indoor head warming the space it's mounted in. Homes here need heat from October through April, with winter nights averaging 29°F, so the system has to be sized to keep up on the coldest nights, not just the mild ones. A contractor can work out how many zones and what capacity the house needs room by room.
