Five months of real heat, every year
Norfolk asks a lot of an air conditioner from May through September. Summer afternoons average 86°F, and the unit you install has to hold that line day after day for five months straight, not just on the hottest week.
Any new central air conditioner installed today has to meet 14.3 SEER2, the federal efficiency minimum set for units built since 2023. That's the baseline. What matters more is sizing it and installing it right for a cooling season this long, so it isn't straining through five months of 86-degree afternoons every year.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors tests and records the contractor, not each job. The license stays with the business across everything it takes on, so what you're checking is the company's standing, not a one-time approval for your installation. Virginia does carve out an exception for small work. Anything under $1,000 does not need a licensed contractor at all. An air conditioner installation runs well past that line, so the license requirement applies here.
Beyond the license, the local building office is what watches this particular job. Most cities and counties require a permit for an air conditioner installation and an inspection once the work is finished. That inspection checks that the unit was put in correctly. It has nothing to do with the installer's credentials, which is what the state license already covers.

- What size air conditioner does my house need?
- The right size depends on your square footage, ceiling height, insulation, window placement, and how much shade the house gets, not just a rule of thumb per square foot. A contractor works this out with a load calculation, checking every room rather than guessing off the home's total size. Putting in one that's too big cools the air fast but shuts off before it pulls the humidity out, so rooms feel clammy. Too small, and it runs nonstop on those 86°F afternoons and still can't keep up.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil and outdoor unit are different ages or from different manufacturers, replacing just the outdoor unit can cause problems. The two are matched to work together, and pairing an old coil with a new condenser often means the system never reaches the efficiency either part was built for. Age matters too. If the indoor coil is old and worn, many contractors will recommend replacing both now rather than risking a coil failure soon after. A contractor can check the coil's condition and tell you whether it's worth keeping.
- Do HVAC contractors in Norfolk need a state license to work on my home?
- Yes. Virginia requires HVAC contractors to hold a state license through the Board for Contractors, and installing an air conditioner qualifies. The license is tied to the contractor, not the job, so it's worth confirming before work starts. You'll also need a permit from the local building office, and the work gets inspected once it's done. A contractor can walk you through what the permit and inspection involve for your home.
