A system that runs hot and cold most of the year
In Muscle Shoals, a mini-split works nearly every month. Homes here need heat from October through April, seven months. Then cooling takes over from May through September, another five. The compressor gets little rest between the two.
Winter nights average 32°F. Summer afternoons average 89°F. The unit has to handle both ends without much of a break in between. Any unit installed new, built in 2023 or later, has to meet the federal minimum for that work. That is 7.5 HSPF2 for heating and 14.3 SEER2 for cooling. Power matters too. In Alabama, 18% of households went at least 24 hours without power in 2024, and this area has logged 7 winter storms and 463 damaging wind events over the past ten years. A mini-split comes back on by itself once power returns, but the outdoor unit still has to be set up to take what those storms bring.

Alabama requires HVAC contractors to hold a state license.
The license is issued by the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors. It covers the contractor, not the job, so the same license stands behind everything they install, a mini-split included.
For this job, that license is what stands behind the person doing the work. Most cities and counties in Alabama also require a permit for a mini-split installation, with an inspection once the work is done, so the job itself gets checked by the local building office in addition to whoever holds the license.

- Is a mini split worth it?
- For the right room or addition, yes. A mini split heats and cools without ductwork, so it works well for a converted garage, a sunroom, or a room that never gets enough air from the main system. Homes here need heat or cooling all 12 months of the year, so a unit that handles both jobs earns its keep in a way it might not somewhere with a shorter season. Whether it makes sense for your house depends on the space and what you already have, and a contractor can walk through that with you.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Each indoor head is sized for the room it serves, so a one-to-one setup handles a single room while a multi-zone setup can cover a few rooms off the same outdoor unit. The right number depends on the size of each room and how the house is laid out, which is something a contractor sizes room by room.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to reach every room. Winter nights here average 32°F from December through February, so the heat pump has to be sized to keep up on the coldest nights, not just the mild ones. A house with an open layout may only need a couple of heads, while one with many closed-off rooms needs one in nearly every room to heat evenly. A contractor can look at the floor plan and work out how many heads it takes to cover the whole house.
