A Hammond mini-split works almost every month of the year
Cooling season here runs April through October, seven months of afternoons near 91°F. Heating picks up November through March, when nights average 42°F. That leaves a mini-split with only a short break each year, so the compressor and the outdoor coil are doing real work most of the time.
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. In a climate that asks for cooling most of the year and real heat the rest, that rating matters more here than in places where the system sits idle half the year. Tangipahoa Parish has also seen 48 damaging wind events over the past ten years, so where the outdoor unit gets mounted and how it is secured is worth getting right the first time.

Louisiana requires HVAC contractors to hold a state license.
The state board tests the contractor and keeps a record of who holds a license, but that license belongs to the business, not to any single job. It tells you the person showing up has passed the state's exam and is on file with the board. It does not mean a state inspector looked at this particular mini-split before or after it went in.
That part comes from the local building office. In most cities and counties, a mini-split installation needs a permit, and an inspection once the work is finished, and that inspection is what checks the work itself rather than the contractor's credentials. The license tells you who is allowed to do the job. The permit and inspection, where the local office requires them, tell you the job was done right.

- Is a mini split worth it?
- For a lot of Hammond homes, yes. You're running cooling from April through October and heat from November through March, so a system that handles both without ductwork earns its keep here. A contractor can look at your layout and tell you where it makes the most sense.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several. Each indoor head is sized and placed for the room it serves, so coverage comes down to how many rooms you want conditioned and how the house is laid out. A contractor will size the outdoor unit to match the total load of every head you're running.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to reach every room. A multi-zone system with one head per room or living area heats the whole house the same way a furnace does, just without ducts moving the air. With winter lows here averaging 42°F, the system has to be sized for that, which is where a contractor's load calculation matters.
