McComb asks for both heat and air, most of the year

A McComb home needs heat or air running eleven months out of the year. Summer runs long, six months of afternoons averaging 91°F, May through October, so the compressor carries most of the workload. Winter is shorter but still asks something real, five months of nights averaging 40°F from December through February.

Most homes here heat with electricity, so a new system is worth sizing for both jobs rather than favoring one. Pike County has also logged 34 damaging wind events over the past ten years, and close to a third of Mississippi households went at least a day without power in 2024. A new installation is a chance to plan for that too, not just for the temperature outside.

Mississippi requires HVAC contractors to hold a state license.

Mississippi's license sits with the contractor, not with each job they do. The State Board of Contractors tests and records the person or company before they can take on work like this, so the license travels with them from house to house rather than getting issued fresh for your installation.

For a job like putting in a new heating and cooling system, that license is what stands behind the contractor's name. Alongside it, most cities and counties in Mississippi require a permit for this kind of installation, and an inspection once the work is finished. That inspection is where someone from the local building office looks at what was installed and confirms it was done right, separate from anything the state license covers.

When should I replace my HVAC system?
Once your furnace or air conditioner needs repairs that keep coming back, or a repair costs a large share of what a new unit would, replacement makes more sense than another fix. Age matters too. An older furnace or AC is more likely to fail at the worst time, and here that means a 91°F afternoon or a 40°F night with nothing to keep the house warm. Homes in this area need heat or cooling 11 months of the year, so a unit that is struggling is worth replacing before it quits rather than after.
Should I replace my furnace and air conditioner at the same time?
If both are near the same age, replacing them together is usually the better move. A furnace and AC installed at the same time were matched to work as a pair, and once one is much older than the other, they stop working as efficiently together. Replacing only one now often means paying to install the second one a few years later anyway. A contractor can look at the age and condition of both and tell you whether it makes sense to do them together or wait.
What happens during an HVAC installation?
A contractor removes the old furnace and air conditioner, or heat pump, and puts in the new equipment, connecting it to your ductwork, gas or electric lines, and the condensate drain. The new system gets tested to make sure it's heating and cooling correctly and running at the right pressures. Replacing a furnace, air conditioner or heat pump here needs a permit from the local building office, and the finished work gets inspected. Expect the crew to walk you through the new thermostat and any new controls before they leave.
