Five months of Suffolk heat, on one system
Suffolk asks for cooling from May through September, five months of the year, with summer afternoons averaging 87°F. That is a long stretch for a system to run well day after day, and it puts real hours on whatever you install.
Any new central air conditioner installed today has to meet a federal minimum of 14.3 SEER2. That baseline is set at the factory, but how the unit is sized and installed still decides how well it holds up to a Suffolk summer.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors tests and records the contractor, not just the business name. That license stays tied to the contractor for every job they take on. Virginia sets one carve-out worth knowing. Work under $1,000 does not need a licensed contractor at all. An air conditioner installation runs well past that, so the contractor doing this job has to hold the license.
Most cities and counties in Virginia require a permit for an air conditioner installation, and someone from the local building office inspects the work once it is done. That inspection happens alongside the state license, not in place of it, and it is a separate check on the job itself.

- What size air conditioner does my house need?
- There is no single number. It depends on your square footage, your insulation, how many windows you have and which way they face, and how many people live in the house. A contractor works this out with a load calculation, not a chart based on home size alone. Getting this wrong in either direction costs you. Too small and it runs constantly without keeping up on the 87°F afternoons you get here all summer. Too large and it cools the air fast but shuts off before it pulls the humidity down, so the house feels clammy even at the temperature you set.
- 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 is not a good match. The two are engineered to work together, and pairing a new condenser with an old coil can mean the system never hits the efficiency or the cooling it is rated for. New systems built since 2023 have to meet a 14.3 SEER2 minimum, and that rating applies to the matched pair, not one component alone. A contractor can look at what you have and tell you whether the coil is worth keeping or whether the whole system should go at once.
- Do HVAC contractors in Suffolk need a state license to work on my home?
- Yes. Virginia requires HVAC contractors to hold a state license, issued through the Board for Contractors. Installing an air conditioner is well past the small-job exception where unlicensed work is allowed, so this job needs a licensed contractor. You will also need a permit from the local building office, with an inspection once the work is finished.
