Eleven months of work for one system
In Madison County a mini-split runs nearly year round. Heat from November through March, when nights average 37°F. Cooling from May through October, with afternoons up around 91°F. Eleven months of the year the system is doing something, with barely a break between the two seasons.
Any mini-split installed new has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Given how much of the year it runs here, that rating is not a formality. It is most of what decides how the house feels for eleven months of the year.

Mississippi requires HVAC contractors to hold a state license.
The Mississippi State Board of Contractors is the one that licensed the contractor before this job. That license belongs to the contractor, not to the mini-split going into your home, so it carries over from whatever job they finished last to this one.
In most cities and counties, installing a mini-split needs a permit from the local building office and an inspection once the work is done. That inspection is separate from the state license. The license says the state tested and has a record of the contractor. The permit and inspection are what checks this particular installation.

- Is a mini split worth it?
- For the right space, yes. A mini split heats and cools without ductwork, so it works well in a room addition, a garage, or a house that relies on window units or baseboard heat. Madison homes need cooling for 6 months and heat for 5, so a unit that handles both jobs earns its keep here. Whether it makes sense for your house depends on how it's heated and cooled now, 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. Single-zone systems serve one room. Multi-zone systems connect several indoor heads to one outdoor condenser, with each head controlling its own room. The right count comes down to the size of the rooms and how much heating and cooling each one needs, which is something a contractor measures room by room before recommending a setup.
- Can a mini split heat a whole house?
- It can, if enough indoor units are placed to cover each room. A multi-zone mini split with heads in every main room can carry a whole house through Madison's heating months, November through March, the same way a central heat pump does. What it takes is matching the number and size of indoor units to the house, room by room, and a contractor sizes that based on the layout and how the home loses heat.
