Five months of heat, and afternoons near 88°F
Pitt County homes run their air conditioner from May through September. That's five months of the compressor cycling on and off most afternoons, with highs averaging 88°F. A new system installed here needs to hold up to that stretch, not just survive it.
Any new central air conditioner has to meet the federal minimum of 14.3 SEER2, so that part isn't a choice. What's worth thinking about is the outdoor unit itself. Over the past ten years the area has logged 67 damaging wind events and 25 hail events, with hail up to 1.5 inches. That unit sits outside through whatever the sky does, for as long as it's installed.

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, so the same license covers the install on your air conditioner and whatever other HVAC work that contractor takes on.
For this job, the license is what stands behind the work. Beyond that, an air conditioner install in most cities and counties in North Carolina needs a permit from the local building office, and the office sends someone out to inspect the finished work.

- What size air conditioner does my house need?
- It depends on your home's square footage, ceiling height, insulation, and how much shade it gets, not just a rule of thumb. A contractor works this out with a load calculation, a room by room measurement of how much heat your house gains on a hot afternoon. With summer highs here averaging 88°F, getting this number right matters more than it would in a milder climate. Too large a unit cools the air fast but shuts off before it pulls the moisture out, leaving rooms clammy. Too small and it runs constantly without ever catching up.
- Should I replace the whole system or just the outdoor unit?
- In most cases replacing just the outdoor unit is not a good option. A contractor will likely recommend replacing the outdoor unit and the indoor coil together, since the two are matched to work as a pair. Pairing a new outdoor unit with an old coil can mean losing much of the efficiency you paid for, along with added strain that shortens its life. If the coil is old enough to need replacing soon anyway, doing both now can make sense. A contractor can look at the coil's condition and tell you whether it is worth keeping.
- Do HVAC contractors in Greenville 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 as a business, not each individual job. Beyond the license, installing an air conditioner also needs a permit from the local building office, with an inspection once the work is finished.
