Ten months a year, one system or the other is running
Lee County only gets a break from heating or cooling two months out of the year. Winter nights average 34°F from December through February, and summer afternoons average 90°F. A new system has to handle both ends without much rest in between.
More than half the homes here heat with electricity, so on those cold nights a heat pump or electric furnace is doing real work, not just topping off a mild chill. Storms here can knock the power out too. Lee County has seen 94 damaging wind events and 6 winter storms over the past ten years, and in 2024, 30% of Mississippi households went at least 24 hours without power. Whatever gets installed should be sized right for the load and set up to come back on its own once the power does.

Mississippi requires HVAC contractors to hold a state license.
The State Board of Contractors tests and licenses HVAC contractors in Mississippi, and that license belongs to the contractor, not to any one job. It tells you the state has reviewed this contractor's qualifications and keeps a record of them. It does not mean the state inspects this particular installation.
That inspection comes from the local building office instead. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit and an inspection once the work is done. The license tells you who is allowed to do the work. The permit and inspection are what checks the work itself.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year, when parts are getting hard to find, or when it can no longer keep the house comfortable through the summer and winter here. A system that short-cycles, runs constantly, or still leaves rooms too hot or too cold is telling you it can't keep up. Homes here need heat from November through March and cooling from May through September, so a system struggling in either stretch leaves you without real comfort for months. If a contractor is already out for a repair, ask them straight whether the fix is worth it or whether the unit is near the end of its run.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together makes sense, but it isn't required. A furnace and air conditioner installed at different times can still work fine together as long as the two are matched for airflow and capacity. Where it matters most is when one unit fails and the other is close behind it. A contractor can look at the age and condition of both and tell you honestly whether pairing the work now saves you a second disruption later.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner or heat pump in place, and connects it to the ductwork, electrical, gas or refrigerant lines the system needs. Once it's running, they test it, checking airflow, temperature output, and that everything is sealed and safe. In most cities and counties around Tupelo, this work needs a permit from the local building office and an inspection once it's finished, so expect that step as part of the job. Mississippi also requires the contractor doing the work to hold a state license, which covers the contractor rather than the individual job.
