What a system in Cumming has to handle

Your new system will run almost year round here. Heat from October through April, seven months, then cooling from May through September, another five. There is barely a break between seasons.

Winter nights average 33°F, so the furnace or heat pump is not fighting deep cold, but it is working most weeks from late fall into spring. Summer afternoons average 86°F, and the AC has to hold that back five months straight. Most homes in the area heat with gas, and whatever you install has to meet the federal minimum efficiency rating for its type. Power outages are common enough here that it is worth asking how the new system behaves when the power drops and comes back.

Georgia requires HVAC contractors to hold a state license.

The State Construction Industry Licensing Board issues that license, and it attaches to the contractor, not to any single job. The state tested this contractor and keeps their license on file, whatever house they're working in.

For an installation like this one, that license is what stands behind the work. In most cities and counties, 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 finished. That inspection is separate from the license. It's the building office checking the installation itself, not the state checking the contractor.

When should I replace my HVAC system?
Replace it when repairs get frequent or a technician tells you the compressor or heat exchanger is failing. A system near the end of its life shows it through higher bills and repair calls that keep coming back, since it has to work harder to do what it used to do easily. Homes here need heat or cooling all 12 months of the year, so there is little rest for equipment that is already struggling. A contractor can look at the age and condition of your system and tell you whether repair still makes sense or replacement is the better move.
Should I replace my furnace and air conditioner at the same time?
If both are old, yes, and here is why. A furnace and air conditioner installed together share a blower and ductwork sized to work as a pair. Replace only one and the new unit has to work with equipment it was not matched to, which can mean uneven heating or cooling and more strain on both. If only one has failed and the other is still young, a contractor can tell you whether pairing them makes sense for your setup.
What happens during an HVAC installation?
A contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place. They connect it to your existing ductwork, wiring, and refrigerant lines, or run new ones where needed. Once it is connected, they test it to make sure it heats and cools correctly and check that airflow through the ducts is right for the new equipment. Georgia requires the contractor doing this work to hold a state license, which is worth confirming before work begins.
