HVAC Repair & Replacement Costs in Arlington, VA (2026)

Furnace repair and replacement pricing

Furnace repairs in Arlington typically run $180 to $700, covering igniter replacement, blower motor repair, or circuit board issues. A full furnace replacement — including a mid-efficiency gas furnace and standard installation — runs $4,000 to $7,500 depending on size and efficiency rating (a high-efficiency 95%+ AFUE unit sits at the top of that range).

Because Arlington County requires a Mechanical Permit for gas-fired equipment regardless of whether it's a straight swap, furnace replacement quotes should always include permit costs and the required Inspection Services Division sign-off. If a contractor's quote doesn't mention a permit for a gas furnace swap, that's a red flag.

Full system replacement and heat pumps

A full HVAC replacement — furnace plus central AC — runs $9,000 to $16,500 in the Arlington market as of 2026, reflecting both DC-metro labor rates and higher-efficiency equipment increasingly required or recommended for the region's humid summers. Heat pump systems, popular as an all-electric alternative, run $7,000 to $13,500 installed, with ducted units toward the lower end and cold-climate variable-speed heat pumps toward the top.

For condos and older buildings without central ductwork — common in parts of Rosslyn and Crystal City — ductless mini-split systems run $3,200 to $5,800 per zone installed, and a typical two- or three-zone condo setup can total $8,000 to $16,000.

Full replacements almost always trigger a Mechanical Permit from Arlington County, and contractors should schedule the required rough-in and final inspections through the county's online permit system before you sign off on the job as complete.

What drives Arlington-specific pricing higher

Three factors push Arlington HVAC replacement costs above Virginia's statewide average: DC-metro labor rates, county permit and inspection requirements, and building-specific access challenges in condos and older rowhomes. A rooftop condenser swap in a Crystal City high-rise, for instance, may require crane or hoist coordination that a single-family install in a more open lot wouldn't need.

Older brick colonials in Cherrydale and Westover sometimes need supplemental ductwork modifications or line-set replacement to accommodate modern high-efficiency equipment, which is a common source of unexpected costs.

Before signing a replacement contract, verify the company's Virginia DPOR contractor license using the state's free License Lookup tool, and confirm they're pulling the required Arlington County permit as part of the job.

Financing and timing your replacement

Full system replacements are a major expense, and most Arlington HVAC contractors offer financing plans, often 0% for 12-18 months through manufacturer-backed programs from brands like Carrier, Trane, or Rheem, which are widely installed in Northern Virginia. Ask each bidder what financing options they offer and compare the total cost, not just the monthly payment.

Timing your replacement in the shoulder seasons (spring or fall) rather than during a summer heat wave can mean better contractor availability, faster scheduling for the Arlington County inspection, and sometimes better pricing since companies aren't as backlogged.

If you're planning a larger home renovation in an older Cherrydale or Westover colonial, coordinate HVAC replacement timing with any other permitted work, since Arlington's Inspection Services Division may require coordinated inspections when multiple systems in the same project are being updated.

For condo owners, factor in extra lead time: HOA approval processes for rooftop or shared-space HVAC work can take several weeks, so start that conversation with your property manager as soon as you know a replacement is likely, well before your old system fully fails.

Efficiency upgrades worth considering

Given Arlington's humid summers, many homeowners upgrading their AC or heat pump now also add a whole-home dehumidifier ($1,200-$2,500 installed) to reduce strain on the cooling system and improve comfort in older homes without great envelope sealing, common in Cherrydale and Westover colonials.

Zoning systems, which let condo owners or colonial homeowners cool bedrooms and living areas independently, typically add $1,500-$3,500 to a replacement project but can meaningfully cut utility bills for homes with uneven layouts, a frequent complaint in older Arlington housing stock.

Rebates are worth chasing too: Dominion Energy periodically offers heat pump and efficiency rebates for Virginia customers, and a reputable Arlington contractor should be able to tell you which current programs your replacement equipment qualifies for, potentially offsetting several hundred dollars of the total project cost.

When comparing bids for a full replacement, make sure each contractor performed a Manual J load calculation specific to your home rather than simply matching the size of your old system — this is especially important in additions or renovated Arlington homes where insulation and window upgrades may have changed the actual cooling load.

Also budget for disposal and haul-away of the old equipment, which most Arlington contractors include but some low-bid outfits quote separately, and always confirm the manufacturer's parts warranty length (typically 10 years on new equipment) versus the separate labor warranty the installing company itself provides, since labor warranties in Arlington commonly range from 1 to 10 years depending on the contractor.

Getting these warranty and disposal details in writing upfront, alongside the Arlington County permit and inspection timeline, gives you a complete picture of the total project cost before work begins rather than discovering add-on fees after installation is underway.
