Five months of Forsyth County heat to plan for
Your air conditioner in Winston-Salem works May through September, with summer afternoons averaging 86°F. That is five months of steady running, not just a few hot weeks.
Forsyth County also sees its share of rough weather. Ten years of records show 174 damaging wind events and 20 hail events, with hail up to 1.75 inches. An outdoor unit sits exposed to all of it, so how it's installed matters as much as the equipment itself. If you're installing new, anything built since 2023 has to meet a federal minimum of 14.3 SEER2.

North Carolina requires HVAC contractors to hold a state license.
The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tested this contractor before handing out the license, and the board keeps a record of who holds one. That license belongs to the contractor, not to your job specifically. It tells you the person or company doing the work met the state's standard to do it.
In most cities and counties, an air conditioner installation like this one also needs a permit from the local building office, with an inspection once the work is done. The license is what backs the contractor. The permit and inspection are what backs the installation itself, checking that what got put in your home meets code.

- What size air conditioner does my house need?
- The right size depends on your square footage, ceiling height, how much shade the house gets, and how well it holds cold air, not just one number off a chart. An undersized unit runs constantly through the summer without keeping up, and an oversized one cools the air fast but shuts off before it pulls the humidity out, leaving the house feeling damp. A contractor works this out with a load calculation, checking the walls, windows, and layout room by room. That's the only way to get it right, since two houses the same size can need different tonnage.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil get replaced together, even if only the outdoor unit failed. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old indoor coil usually means the system never runs the way either piece was designed to. Refrigerant type is part of this too. Older systems use refrigerants that new outdoor units aren't built to run on. A contractor can look at the age and condition of the indoor coil and tell you whether it can pair with new equipment, but replacing just the outdoor unit is rarely the right call.
- Do HVAC contractors in Winston-Salem need a state license to work on my home?
- Yes. North Carolina requires HVAC contractors to hold a state license, issued through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. That license covers the contractor doing the work, not the specific job. On top of that, installing a new air conditioner in Winston-Salem typically needs a permit from the local building office, with an inspection once the work is finished. Asking to see a contractor's license before work starts is reasonable, and confirming the permit gets pulled is worth doing too.
