A new mini-split here works nearly year round
Lafayette Parish calls for heat or cooling every month of the year. Summer runs long, April through October, with afternoons averaging 91°F, so the compressor is doing real work most of the year it's installed for. Winter is shorter, five months, November through March, and nights averaging 44°F still mean the heat pump side is running most nights.
Any new mini-split has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With seven months of cooling ahead of five months of heating, it's the cooling side that gets asked to do more here.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors tests contractors before they can hold this license, and it keeps a record of who holds one. The license belongs to the contractor, not to any single job, so it tells you the person or company has met the state's standard, not that this particular installation has been checked.
That check comes from the local building office. A mini-split installation in most cities and parishes needs a permit before the work starts and an inspection once it is done, and that inspection is what confirms this specific job was done right, separate from whatever license the contractor carries.

- Is a mini split worth it?
- For most homes here, yes. Winter lows average 44°F and summer afternoons average 91°F, so you're heating or cooling the house nearly all year, and a mini split handles both jobs from the same outdoor unit. It also gives you zone control, so a room you don't use can stay off while the rest of the house runs. A contractor can look at your layout and tell you whether it beats extending ductwork or patching an old system.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several. A single-zone system covers one room or open area. A multi-zone system splits the same outdoor unit across several indoor heads, each with its own thermostat, so bedrooms, living areas, and additions can all run independently. How many zones a house needs comes down to square footage, layout, and how the rooms are used, which a contractor sizes room by room.
- Can a mini split heat a whole house?
- It can, with enough indoor heads placed to cover every room. That's worth considering here since heat pumps run on electricity and most homes in this area already heat that way. A ducted system moves warm air through one network of ducts, but a mini split heats room by room instead, so each zone needs its own indoor unit sized for that space. A contractor can walk the house and lay out how many zones it would take to cover it fully.
