Ten months of work a year, in a county that loses power
Gadsden asks a mini-split to run almost year round. Winters average 34°F and homes here need heat November through March. Summers average 89°F with cooling needed May through September. That leaves only two months when the system can rest.
A new unit installed here has to meet the federal minimum for split-system heat pumps. That means 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the floor for anything manufactured from 2023 on. Most homes in the area heat with electricity, so a mini-split often carries the whole heating load, not just part of it. Etowah County has also logged 71 damaging wind events over the past ten years, and Alabama saw 18% of households lose power for at least a day in 2024. A mini-split that comes back on by itself once power returns matters here.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors tests and licenses HVAC contractors across the state. That license belongs to the contractor, not to any single job, so it stands behind whoever does your install whether they work in Gadsden or out in the county.
For a mini-split, that license is the main protection you have, but the local building office still has a role. Most cities and counties in Alabama require a permit for this kind of installation, with an inspection once the work is done. That inspection is what checks the mini-split was installed correctly, separate from whatever the state license already tells you about the contractor doing the work.

- Is a mini split worth it?
- For most homes here, yes, especially in a room a duct never reaches well or in a house that heats with electric resistance now. Alabama Board licensed contractors size these systems around what a room actually loses in winter and gains in summer, so the unit runs efficiently rather than short-cycling. With winter lows near 34°F and summer afternoons near 89°F, a mini split has to work through a real swing in both directions, and the heat pump models sold now are built for that. Whether it makes sense for your house depends on how the space is laid out now, which is something a contractor should walk through in person.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. A single-zone system heats and cools one room or one open area well. A multi-zone system ties one outdoor condenser to multiple indoor heads, each with its own thermostat, so bedrooms, a living room, and an addition can all run independently. How many zones one outdoor unit can carry depends on its capacity and on what each room needs, which a contractor works out by measuring the space, not by guessing at a number.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to cover the rooms that need heat and the outdoor unit is sized for the whole load, not just one room. Homes here need heat from November through March, so the system has to hold up on the coldest nights of that stretch, not just the mild ones. A multi-zone heat pump system built for whole-house use is a different design decision than adding one head to a single room, and a contractor should size it against the house itself before you count on it as your only heat.
