What Canton summers ask of a new air conditioner
Summer afternoons in Canton average 87°F, and a new air conditioner here runs from May through September to keep up. That is five months of steady work each year, cooling through the hottest part of the day.
Any central air conditioner installed new has to meet the federal efficiency minimum of 14.3 SEER2. Cherokee County has also seen its share of hail and wind over the past ten years, so the outdoor unit needs to be set up and installed correctly, not just sized for the heat.

Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board is the body that tests and records HVAC contractors in Georgia. That license belongs to the contractor, not to any single job, so it travels with them from one house to the next rather than being issued fresh for your installation.
For an air conditioner installation, the license tells you the contractor met the state's standard to do this kind of work at all. In most cities and counties, a job like this also needs a permit from the local building office and an inspection once the work is done. That inspection is where someone checks the installation itself, separate from and in addition to the license the contractor already holds.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade and window area you have, and how well your attic and walls hold insulation. A unit that's too big cools the room fast but shuts off before it pulls the humidity out, so the house feels clammy. A unit that's too small runs constantly and never quite catches up, especially on the hot afternoons here that hit around 87°F. A contractor sizes the system with a load calculation on your actual house, not a chart based on square footage alone.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing only the outdoor unit usually isn't a straightforward swap. The two are matched to work together, and pairing a new condenser with an old coil can mean it never reaches the efficiency or cooling capacity it's rated for. Age matters too. New systems sold today have to meet a 14.3 SEER2 minimum, so if your indoor coil predates that, matching it to a new outdoor unit gets harder. A contractor can look at both halves of your system and tell you whether they're worth pairing or whether it's time to replace them together.
- Do HVAC contractors in Canton need a state license to work on my home?
- Yes. Georgia requires HVAC contractors to hold a state license, issued by the State Construction Industry Licensing Board. For an AC installation, you'll also need a permit from the local building office, and the work gets inspected once it's done. Ask to see the license before work starts, and confirm the permit gets pulled in your name for the address.
