Five months of Hampton summer heat on one system
Your air conditioner runs May through September here, and on the hot afternoons it's built for, the temperature outside is pushing 87°F. That's five months of steady work, not just a few weeks of catching up on the hottest days.
If you're installing new, anything built since 2023 has to meet 14.3 SEER2, the federal minimum for efficiency. Whoever installs it should size the unit to your house, not just swap in the same tonnage that was there before.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors tests and licenses the contractor, not the job itself, so the license travels with the company across every project it takes on in Virginia. Work under $1,000 falls outside that requirement, but an air conditioner installation runs well past that line.
Because this is an installation, the license is what stands behind the person doing the work, but it is not the only check on it. Most cities and counties in Virginia require a permit for a new air conditioner, and an inspector checks the finished work before it is signed off. That inspection is separate from the license and looks at the installation itself, not the company's standing.

- What size air conditioner does my house need?
- There's no single answer that fits every house, and a bigger unit is not a safer bet. A contractor sizes the system by measuring your square footage, your windows, your insulation, and how much shade your house gets, then running that through a load calculation. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. An undersized one runs constantly and never quite catches up on those 87°F afternoons. The only reliable way to get the number right is to have someone measure your house, not guess from its size on paper.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old indoor coil usually means losing the efficiency gain you paid for, and it can void the warranty on the new equipment. If your indoor coil is already old and worn, replacing only the outdoor unit now often means paying a contractor to come back for the coil later. A contractor can look at the age and condition of what you have and tell you whether the coil is worth keeping.
- Do HVAC contractors in Hampton 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 falls under that requirement. The license covers the contractor, not the individual job. A full AC installation will also need a permit from the local building office, with an inspection once the work is done. Asking to see the license before work starts is a reasonable thing to do.
