Ten months of work a year for a new mini-split in Lauderdale County
Winter nights here average 37°F, and summer afternoons average 90°F. Between the two, a mini-split is running November through March and again May through September, ten months a year with barely a break between them.
Any mini-split installed new has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Most homes in Lauderdale County heat with electricity, so that heating side matters as much as the cooling side does. Storms are part of the picture too. The county has seen 126 damaging wind events over the past ten years, and close to a third of Mississippi households lost power for at least a day in 2024. A mini-split that comes back on by itself once power returns is one less thing to deal with after a storm.

Mississippi requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to this particular mini-split job. Mississippi's State Board of Contractors tested that contractor and keeps a record of them, and that record stands behind every job they take on, not just this one.
In most cities and counties in Mississippi, installing a mini-split needs a permit from the local building office, with an inspection once the work is finished. That inspection is separate from the state license and checks the installation itself, not the contractor's record.

- Is a mini split worth it?
- For most homes needing both heat and cooling, yes. Meridian needs heat from November through March and cooling from May through September, so a system that runs ten months of the year gets real use here. A mini split also keeps working zone by zone, so a problem in one room does not leave the whole house without heat or air.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. A multi-zone system connects more than one indoor unit to a single outdoor condenser, and each indoor unit has its own thermostat so rooms can be set differently. A contractor sizes the system to the square footage and layout of the specific house, since how many rooms it can cover depends on how much capacity each room needs.
- Can a mini split heat a whole house?
- Yes, if it's sized and placed for the whole house rather than one or two rooms. Winter nights here average 37°F, so every zone needs enough capacity to keep up on the coldest nights, not just the mild ones. A contractor can work out how many indoor units the house needs and where they go to reach every room.
