What a system here has to handle
Canton asks for heat from October through April and cooling from May through September, so a new system runs almost all year with barely a break. Winter nights average 33°F, mild compared to farther north, but that furnace or heat pump still has to hold steady for seven months straight. Come summer, afternoons average 87°F and the system switches to cooling for five more.
Most homes here heat with gas, and whatever you install has to meet the current federal efficiency minimum. Storms are part of the picture too. Cherokee County has seen 149 damaging wind events and 6 winter storms over the past ten years, and across Georgia, 31% of households lost power for at least 24 hours in 2024. A new install is worth planning with that in mind.

Georgia requires HVAC contractors to hold a state license.
Georgia licenses the contractor, not the job, through the State Construction Industry Licensing Board. That means the board tested this contractor and keeps a record of them, and that same license has to stand behind every installation they take on, not just this one.
For a heating and cooling installation, that license is what stands behind the work itself. In most cities and counties in Georgia, putting in a new furnace, air conditioner or heat pump also needs a permit from the local building office, with an inspection once the work is done. The inspection looks at how this system was installed in this house, which is separate from what the license covers.

- When should I replace my HVAC system?
- Replace it when your furnace or air conditioner is breaking down more than once a season, or when the repairs keep adding up. An older system working harder than it should is more likely to fail right when you need it most, whether that is a winter night near 33°F or a summer afternoon near 87°F. If a contractor tells you the repair costs a good fraction of a new system, that's usually the point to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to do them together. A furnace and air conditioner installed at the same time are matched to work as a pair, and since homes here need heat or cooling all 12 months of the year, there's no slow season to stagger the work around. If one unit is much newer than the other, a contractor can look at both and tell you whether replacing just the older one makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, gas line or refrigerant lines, and electrical. Once it's connected, they check the airflow, the refrigerant charge, and the gas pressure or ignition, then test the system through a full heating and cooling cycle. With most homes here heating with gas, installations often include a check of the venting and gas connections to make sure combustion gases are leaving the house correctly. The exact steps depend on what equipment you're replacing and how your current system is set up, so a contractor will walk you through what applies to your house.
