Five months of real heat, every year
Greensboro summers run May through September, five months where the afternoon high averages 87°F. That is a long stretch for a compressor to run day after day, and it means a new system needs to hold up to steady, repeated use, not just the occasional hot week.
Guilford County also sees its share of hail and wind, 30 hail events and 166 damaging wind events recorded over the last ten years, with hail up to 1.75 inches. The outdoor unit sits exposed to that. Any new install built since 2023 has to meet a federal minimum of 14.3 SEER2, so the efficiency floor is already set. What matters here is picking a system and a setup that can take five months of heat and whatever the weather throws at the unit outside.

North Carolina requires HVAC contractors to hold a state license.
The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tests contractors before it licenses them, and it keeps their record on file. The license belongs to the contractor, not to any one job, so the same license that covers this installation covered whatever job they did before it.
The license is what stands behind the contractor. The permit is what stands behind this job. In most cities and counties here, putting in a new air conditioner needs a permit from the local building office, and an inspector checks the finished work once it's done. That inspection is what confirms this particular installation was done right.

- What size air conditioner does my house need?
- There's no number you can guess at from square footage alone. A contractor works this out with a load calculation, which looks at your home's square footage, insulation, windows, and layout together, because a unit that's too big will cycle on and off without properly removing humidity, and one that's too small will run constantly and still struggle on the hottest afternoons. With summer highs here averaging 87°F, getting this right matters more than picking a unit based on what the last one was rated at.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if the outdoor unit is failing, the whole system gets replaced rather than just that piece. The indoor coil and outdoor unit are matched to work together, and pairing a new outdoor unit with an old indoor coil often means the system won't run at the efficiency either part was built for. A contractor can look at the age and condition of both pieces and tell you whether matching is possible or whether full replacement makes more sense.
- Do HVAC contractors in Greensboro 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 single job, so it covers them for installing your air conditioner just as it would for other HVAC work. You'll also need a permit from the local building office for the installation, with an inspection once the work is finished.
