Eleven months of work for a Jackson mini-split
Your mini-split only gets a break for about a month a year here. Cooling runs May through October against afternoons that average 91°F, then heating takes over November through March with winter nights averaging 38°F. That is eleven months of the year the compressor is doing something.
Any new unit installed now falls under the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Hinds County also sees its share of damaging wind, 270 events recorded over the past ten years, and just over half of homes here heat with electricity. When the power goes out, a mini-split heat pump comes back on by itself once it's restored, so it will start heating or cooling again without anyone resetting it.

Mississippi requires HVAC contractors to hold a state license.
The state tests the contractor before handing out that license, and it keeps a record of who holds one. What it does not do is inspect this particular mini-split job. The license tells you the person or company doing the work met the state's standard to hold that credential in the first place, not that this installation was checked once it was done.
That second check comes from the local building office. In most cities and counties, installing a mini-split needs a permit and an inspection once the work is finished, separate from anything the state licensing board does. The license says the contractor is qualified. The permit and inspection say this specific installation was looked at by someone from the local government before it was signed off.

- Is a mini split worth it?
- For most homes here, yes, especially in a room that never gets comfortable off the main system. It handles both heating and cooling from one unit, which matters here since homes need one or the other 11 months of the year. It also gives you a backup source of heat or cooling if the main system goes down, which is worth something given how often storms here knock out power. A contractor can look at the space you want covered and tell you if it makes sense for that room.
- 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 tie several indoor heads to one outdoor condenser, each with its own thermostat, so you can heat or cool a few rooms separately. The more zones you add, the more the outdoor unit has to be sized for all of them running at once. A contractor can size the system for the rooms you actually want covered.
- Can a mini split heat a whole house?
- It can, if the system is sized and placed for the whole house rather than one or two rooms. That takes enough indoor heads in the right locations, and an outdoor unit sized to keep up when it's 38°F outside, which is the average winter low here. A mini split rated for cold climates will keep producing heat at that temperature, but the sizing has to account for it. A contractor can work out how many zones your house needs and whether the layout suits a ducted or ductless setup.
