Central Air Installation Cost in Northern Virginia (2026)
Central air installation cost ranges for Northern Virginia, and what actually moves the price on a new system.
Typical Installation Price
A new central air system in Northern Virginia usually runs $6,000 to $14,000 installed. The spread comes from the size of your home, the efficiency rating you choose, and whether your ductwork needs any work.
What Moves the Number
A bigger home needs more cooling capacity, which costs more. A high-efficiency unit costs more upfront but lowers your summer electric bills. If your ducts leak or are undersized, fixing that adds to the job but protects the new system.
New System or Replacement
Swapping a like-for-like unit is the simpler job. Moving to a heat pump or adding zoning changes the scope. We size the system to your actual home with a load calculation, not a guess off the old unit's label.
Getting an Exact Quote
The only honest number comes from an on-site look. We measure your home, check your ductwork, and hand you a written quote before anything is ordered. No pressure and no vague estimates. Replacement quotes are free, and the price we write down is the price you pay once you approve the work.
Common questions
How long does a central air install take?
