Eleven months of work for your new system
In Brookhaven, a mini-split earns its keep. Winter nights average 39°F from December through February, and summer afternoons run 91°F, so the unit you install will be asked to heat or cool 11 months out of the year with only a short break each spring and fall.
Any mini-split installed new has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With most homes here heating with electricity, sizing the unit correctly for both the summer heat and the mild winter lows matters more than chasing a rating above that minimum.

Mississippi requires HVAC contractors to hold a state license.
The state exam covers the trade generally, and the license stays with the contractor rather than being issued fresh for each installation. So the license tells you the person or company running the job has been tested and is on record with the State Board of Contractors, not that this specific mini-split job was reviewed ahead of time.
That oversight sits alongside the local one. In most cities and counties in Lincoln County, installing a mini-split needs a permit from the local building office, and an inspection once the work is done. The permit and inspection check the installation itself, the license checks the contractor doing it.

- Is a mini split worth it?
- For most homes, yes, especially for heating or cooling a room or space the main system does not reach well. Homes here need heat or cooling 11 months out of the year, so a system that works efficiently in both directions earns its keep. A mini split installed today also has to meet the federal minimums of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, so it is built to handle both jobs. Whether it makes sense for your house depends on what you are trying to condition and what is already there, and a contractor can walk you through that.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Multi-zone systems are built to run more than one indoor head off a single outdoor condenser, with each head controlling its own room. Each indoor head is sized for the room it is in, so the right count comes down to how many rooms you need conditioned and how big they are. A contractor sizing the job will look at each room before deciding how many zones you need.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to cover every room, but it depends on the layout of the house. A mini split heat pump works well in winters like the ones here, where nights average 39°F, since heat pumps manufactured now have to meet a 7.5 HSPF2 minimum for heating performance. Whole house coverage usually means a multi-zone setup with a head in each room or open area, not just one or two units. A contractor can look at the house and tell you how many zones it would take to heat all of it.
