Ten months of work a year for your mini-split
Millbrook asks for heat from November through March and cooling from May through September. That is ten months where your mini-split is doing one job or the other. Winter nights averaging 37°F keep the heat pump side running through the cold months, and summer afternoons near 91°F keep the compressor working hard the rest of the year.
Most homes here heat with electricity, so the heat pump side of a mini-split is doing real work, not backup work. Any unit installed new has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum for split-system heat pumps built from 2023 on. Alabama sees enough power outages that it helps to know most mini-splits start back up on their own once power returns, with no reset needed.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors tested the contractor for this license and keeps a record of them. That license belongs to the contractor, not to any one job, so it covers the person doing the work rather than this particular installation.
For the mini-split going in, the license is what stands behind the contractor, and most cities and counties in Alabama also require a permit for this kind of installation, with an inspection once the work is done. The permit and inspection are separate from the state license and come from the local building office, not the board.

- Is a mini split worth it?
- For most homes here, yes, especially if a room runs hot in summer or cold in winter without ductwork to fix it. Millbrook needs heat from November through March and cooling from May through September, so a system that does both well earns its keep most of the year. A contractor can look at your specific rooms and tell you where it makes sense and where it does not.
- 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 split the output across several indoor heads, each with its own thermostat, so a bedroom and a living room can run at different temperatures at the same time. How many zones a given outdoor unit supports depends on its size and the total load of the rooms you want covered, which a contractor works out room by room.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to cover the rooms that need heat. A mini split is a heat pump, so it pulls in outside heat and moves it indoors, the same way it moves heat out in summer. Millbrook winter nights average 37°F, which a properly sized heat pump handles without issue. Whether one outdoor unit with multiple zones covers your whole house or you need more than one system depends on the size of the house and how it is laid out, which a contractor would need to see to size correctly.
