Eleven months of the year, your system is working
Only one month here asks nothing of your heating or cooling. Summer afternoons average 91°F, and that heat holds from May through October, six months of cooling. Winter is shorter, November through March, and nights average 38°F. A new system in Hinds County has to handle both ends of that without much rest between them.
More than half the homes here heat with electricity, so a system that leans hard on the grid is leaning on something that isn't always steady. Nearly a third of Mississippi households lost power for at least a day in 2024, and the county has seen 270 damaging wind events over the past ten years. A new install is worth planning around that, not just around the temperature swings.

Mississippi requires HVAC contractors to hold a state license.
The state's license belongs to the contractor, not to any single job. It means the State Board of Contractors has tested and keeps a record of the person or company taking on the work, and that record follows them from one job to the next rather than resetting each time.
For an installation like this one, the license covers who is qualified to do the work, but most cities and counties also require a permit from the local building office once you replace a furnace, air conditioner or heat pump, along with an inspection when the job is finished. That permit and inspection are separate from the license. They are how the installation itself gets checked, not just the contractor doing it.

- When should I replace my HVAC system?
- Replace it when repairs get frequent or it can't keep up on the coldest nights or hottest afternoons. An older furnace or air conditioner is more likely to fail right when you need it, and here that means a winter night near 38°F or a summer afternoon near 91°F. If a contractor has already been out more than once this year for the same unit, that's usually a sign the next breakdown is close. Waiting for a full failure often means living without heat or cooling until someone can get to the repair.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often the better choice, but it depends on the condition of each one. A furnace and air conditioner installed at the same time were matched to work together, and pairing a new outdoor unit with an old furnace can mean one part limits the other. Homes here need heat from November through March and cooling from May through October, so both units get real use most of the year and tend to wear down on a similar schedule. A contractor can look at the age and condition of each one and tell you whether it's worth keeping.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner and coil, connects it to the ductwork, wiring and refrigerant lines, and tests it before leaving. This includes checking the thermostat, checking airflow at the vents, and confirming the system cycles on and shuts off the way it should. In most cities and counties here, replacing a furnace or air conditioner needs a permit from the local building office, and an inspector checks the work once it's done. That inspection is there to confirm the installation was done to code, not just that the system turns on.
