A system that works almost every month of the year
In Pascagoula, cooling runs April through October, seven months of afternoons averaging 90°F. Winter is shorter, November through March, and nights average 42°F. That leaves only a handful of days when a heating and cooling system gets to rest.
Most homes here heat with electricity, so the outdoor unit and the air handler both carry the load in both directions, all year. Storms are part of the picture too. Jackson County has seen 29 damaging wind events over the past ten years, and across Mississippi, 30% of households went at least 24 hours without power in 2024. A new system should be sized and installed to handle the heat, the cold, and the chance the power goes out before it comes back on.

Mississippi requires HVAC contractors to hold a state license.
The State Board of Contractors issues that license, and it belongs to the contractor, not to any single job. That covers who is allowed to take on work like this, not how any one installation turns out.
For a furnace and air conditioner or heat pump going in together, the license tells you the contractor is the one the state allows to do this work. Most cities and counties also require a permit from the local building office for a job like this, with an inspection once it's done. The license covers who's doing the work. The permit and inspection cover whether this particular installation was done right.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth or when the system can't keep the house comfortable during the months it has to work hardest. Homes here need cooling April through October and heat November through March, so a system that struggles during those stretches has little time each year to rest and recover. If you're calling for the same repair a second time in a year or two, that's usually the sign it's time to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- In most homes it makes sense, especially if both are close in age, since a furnace and air conditioner installed together are matched to work as one system. Mismatched equipment can run less efficiently and wear out sooner. A contractor can look at both and tell you whether the newer one has enough life left to wait.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, connecting it to the ductwork, refrigerant lines, gas or electric supply, and thermostat. Replacing this kind of equipment needs a permit from the local building office in most cities and counties, along with an inspection once the work is done. In Mississippi, the contractor doing the work has to hold a state license, since the license covers the contractor rather than the individual job.
