Cullman runs its mini-splits year round
Heat is needed October through April here, and cooling May through September. Together that covers all twelve months, so a new mini-split does not get a season off. It goes straight from one job to the other.
Winter nights average 33°F and summer afternoons average 88°F, a working range on both ends of the thermostat. Any new mini-split is a split-system heat pump under federal rules, and units built since January 2023 must meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors issues that license, and it covers the contractor, not each job. That means the state has tested and keeps a record of the person or company doing the work, but the license itself does not follow the mini-split through your wall. It is the same license whether the job is small or large.
For this installation, the license is what stands behind the contractor. The permit is what stands behind the work itself. In most cities and counties here, putting in a mini-split needs a permit from the local building office, and the finished job gets an inspection before it is signed off. That inspection is what checks the installation, separate from the license the contractor already holds.

- Is a mini split worth it?
- For most homes here, yes, especially if you're heating or cooling a room your main system doesn't reach well, like a garage, sunroom, or addition. Cullman needs heat from October through April and cooling from May through September, so a unit here runs nearly all year. Because it's a heat pump, one system handles both jobs instead of you needing separate equipment. A contractor can look at the space and tell you whether it makes more sense than extending ductwork.
- How many rooms can a mini split cover?
- A single indoor unit is sized for one room or one open space, but multi-zone systems let one outdoor unit run several indoor heads, each in a different room. Each zone has its own thermostat, so you can heat or cool only the rooms in use. How many zones a single outdoor unit can support depends on its size and the square footage of each room, so a contractor will need to measure the space to give you an exact number.
- Can a mini split heat a whole house?
- It can, but only if it's sized and placed for that from the start, with enough zones to reach every room. Winter nights here average 33°F, so the heat pump has to keep up with real cold, not just take the edge off. A single indoor unit is meant for the space it's in, not the rooms around it. Whole-house coverage usually means a multi-zone layout planned room by room, which is something a contractor works out based on the home.
