Typical AC Replacement Costs in Northern Virginia
For a standard central AC replacement in the Annandale area, homeowners typically pay between $4,500 and $12,000. A basic single-stage unit on an existing duct system with no complications sits at the lower end — around $4,500 to $6,500. Mid-range two-stage systems with a higher SEER2 rating generally fall between $6,500 and $9,000. Premium variable-speed systems, heat pump conversions, or installations that require new ductwork or electrical upgrades can range from $9,000 to $12,000+. These figures include equipment, labor, permits, and standard materials. Your actual cost depends on your home's layout, the condition of existing infrastructure, and the equipment you choose.
"As always, Paul at AVA Air is amazing. We've been using him for years on our main home and several rentals. He is professional, on-time, easy to work with and always gives us great results and great pricing!"

The biggest variables are system size (measured in tons — most Northern Virginia homes need 2.5 to 5 tons), efficiency rating (SEER2), and whether you're doing a straight swap or upgrading to a different system type like a heat pump. Ductwork condition matters too — if your ducts are leaky, undersized, or poorly routed, fixing them during the install adds cost but dramatically improves performance. Finally, accessibility plays a role: a unit in an easy-access basement is simpler (and cheaper) to install than one in a tight attic or crawlspace.
We break all of this down during your free estimate, so you understand exactly what's driving the price and where you have options.
"We like that the owner, Paul was onsite for the entire install. Very tidy and clearly communicated all aspects of the project. Bonus that he warranties on his work. We recommend supporting this local business."
