Five months of cooling in Thomasville summer heat
Your air conditioner runs May through September here, with summer afternoons averaging 87°F. That is five months of steady work, most of it in the hottest part of the day when the unit cycles on and stays on longest.
Davidson County has also logged 129 damaging wind events and 26 hail events over the past ten years, some with hailstones up to 2 inches. Whatever gets installed sits outside through that. If it's new, it has to meet the federal minimum of 14.3 SEER2, so it starts out running as efficiently as the law requires.

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 this one job. It tells you the person or company doing the work met the state's standard to do HVAC work at all.
That license is what stands behind the person doing this install. In most cities and counties, putting in a new air conditioner also needs a permit from the local building office, with an inspection once the work is done. That inspection is separate from the license and checks the installation itself, not the contractor's standing.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor looks at your insulation, your windows, your ductwork, and how much shade your house gets before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. An undersized one runs constantly through the cooling months and still can't keep up on the hottest afternoons, and here that season runs May through September.
- 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 just the outdoor unit usually isn't a good match. The coil and condenser are matched to work together, and pairing an old coil with a new condenser can mean the system never hits its rated efficiency. A contractor can check the age and condition of both and tell you whether a matched pair makes more sense than a single swap. Any new outdoor unit installed today has to meet the 14.3 SEER2 minimum, so that's worth knowing going in.
- Do HVAC contractors in Thomasville 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. The license belongs to the contractor, not to any one job, so it's worth asking to see it before work starts. Installing an air conditioner also typically needs a permit from the local building office, with an inspection once the job is done.
