Meridian asks for both, most of the year
Your new system has to cover ten months of work a year here. Heat runs November through March, when nights average 37 degrees. Cooling runs May through September, when afternoons average 90 degrees. Only two months sit outside either job.
Most homes in the area heat with electricity, so one unit often carries both seasons. Wind is the other thing worth planning for. Lauderdale County has logged 126 damaging wind events over the past ten years, and across Mississippi, close to a third of households went at least a day without power in 2024. Ask your contractor how the system you choose comes back on once power returns.

Mississippi requires HVAC contractors to hold a state license.
Mississippi licenses HVAC contractors through the State Board of Contractors. That license belongs to the contractor, not to this one job, so it stays with them from one installation to the next rather than being issued fresh each time.
For this job, the license is what stands behind the contractor doing the work, but most cities and counties in Mississippi also require a permit from the local building office for a system replacement like this one, with an inspection once it's done.

- When should I replace my HVAC system?
- Once a furnace or air conditioner is old enough that repairs keep coming back, replacing it is usually the better call. Ten months out of the year a home in Meridian needs either heat or cooling, so a system that's struggling doesn't get much rest to recover from wear. Rising energy bills without a clear cause, a unit that cycles on and off too often, and repair costs that keep climbing are the signs worth paying attention to. A contractor can look at the actual age and condition of your system and tell you whether another repair makes sense or whether you're past that point.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at different times can still work fine together as long as both are sized and matched correctly. Mismatched systems don't always coordinate well, and one unit working harder to compensate for the other wears out faster. A contractor looking at both units can tell you whether one has real life left in it or whether pairing new equipment with an old unit is going to cause problems.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in place, then connects it to the ductwork, the electrical supply, and the refrigerant lines or gas line depending on what's being installed. The system gets wired to the thermostat and tested to make sure it runs correctly, including checking airflow and, for cooling equipment, the refrigerant charge. In most cities and counties around Meridian, this job needs a permit from the local building office, and an inspector checks the work once it's done. Mississippi also requires the contractor doing the installation to hold a state license through the State Board of Contractors.
