Ten months of the year, one system carries the load
From November through March your mini-split is the heat source, working against nights that average 34°F. From May through September it's the only thing keeping the house cool through afternoons that average 90°F. Ten months of the year, it's doing one job or the other, with little time off between.
A unit built for that kind of year still has to meet the same federal floor as any other. Any mini-split manufactured from 2023 on has to hit at least 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Most homes here heat with electricity, so when the power goes out, the heat goes with it. Walker County has seen 65 damaging wind events over the past ten years, and Alabama households lost power for a day or more often enough in 2024 that it's worth asking how a new system handles the outages, not just the temperatures.

Alabama requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to the job, so it covers the business doing the work rather than this specific installation. The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors is the one that tested them and keeps that record.
For this installation, the license is what stands behind the contractor's name, and the permit is what stands behind the work itself. In Walker County, installing a mini-split will typically need a permit from the local building office along with an inspection once the work is finished. That inspection is what checks the wiring and the physical work, not the license.

- Is a mini split worth it?
- For most homes here, yes, especially in a room that never gets comfortable off the main system. Winters average 34°F and summers average 90°F here, and a mini split handles both, so it earns its keep across most of the year. It also gives you a heat source that doesn't depend on ductwork, which matters if delivery to one part of the house is uneven. A contractor can look at your specific rooms and tell you where it makes the most sense.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Multi-zone systems are built to support more than one indoor head from a single outdoor unit, with each head controlling its own room. The right number for your house depends on the size of the rooms and how much heating and cooling each one needs, which is why a contractor sizes the system room by room rather than guessing at a number.
- Can a mini split heat a whole house?
- It can, if it's sized and placed for that from the start. A multi-zone mini split with enough indoor heads can cover an entire house the same way a central system does, and it has to hold up through winter nights that average 34°F here. That takes a real heating load calculation for the house, not a rough guess, so a contractor should work out the sizing before you count on it as your only heat source.
