Ten months of the year, one system doing both jobs
Alabaster homes need heat or cooling ten months a year. Heat runs November through March, with winter nights averaging 35°F. Cooling runs May through September, with afternoons averaging 90°F. A mini-split installed here spends most of the year working, not sitting idle.
Any heat pump mini-split built from 2023 on has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That is the minimum for handling both a 35°F night and a 90°F afternoon, not just one or the other. With 55.7% of homes here heating with electricity, the mini-split is often the thing keeping the house warm all winter, not just cooling it in summer.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors tests contractors before they can hold this license, and it keeps a record of who holds one. That license covers the contractor, not the job itself, so it tells you the person or company doing your mini-split install has met the state's standard, but it does not stand in for anything done at your house.
For the install itself, most cities and counties in Alabama require a permit before the mini-split goes in, and an inspection once the work is done. That inspection is what checks the actual work at your address, separate from whatever the state license already says about the contractor.

- Is a mini split worth it?
- For the right room or the right house, yes. A mini split heats and cools without ducts, so it works well for an add-on, a converted garage, or a house that never had ductwork run to begin with. Alabaster needs heat from November through March and cooling from May through September, so a system that handles both jobs well earns its keep here. A contractor can look at your house and tell you whether a mini split makes more sense than extending existing ductwork or adding a separate system.
- How many rooms can a mini split cover?
- A single outdoor unit can run more than one indoor head, so a mini split can cover several rooms at once. Each indoor head is sized to the room it serves, and the outdoor unit has to be sized to match the total load of every room combined. A contractor will calculate that load room by room rather than guess at it, since undersizing means rooms that never get comfortable and oversizing wastes money and runs the system in short, inefficient cycles.
- Can a mini split heat a whole house?
- It can, if it is sized and laid out for the whole house from the start. That means an outdoor unit matched to the full heating load and enough indoor heads placed so no room is left without one, including on winter nights here that average 35°F. A mini split installed for one or two rooms will not stretch to heat the rest of the house, so this is a different job from a single-room install and needs to be planned that way from the beginning.
