Arlington price range against the U.S. range, with the climate and housing numbers behind it.

Arlington Weather and HVAC Load

NOAA's 1991-2020 climate normals put Arlington at 3,769 heating degree days and 1,737 cooling degree days per year. Neither season dominates in Arlington. That balance is a big reason heat pumps and dual-fuel systems sell well in Virginia. On average, Arlington gets 60 freezing nights and 40 days above 90°F per year. Snowfall averages about 14 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

Arlington Housing Stock

Census figures put the median build year in Arlington at 1976, so a typical house here has about 50 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 41.8% of occupied homes, roughly 47,000 households. Homes here have a median value of $864,800 and households a median income of $140,160. Those two numbers drive the labor adjustment in our estimate.

Arlington County had 1 hail day and 28 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.25 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

Symptoms Worth a Service Call

  • The outdoor unit hums, but the fan doesn't spin
  • The AC runs, but the air coming out is warm
  • Ice on the refrigerant lines or the indoor coil
  • The system cycles on and off every few minutes
  • The breaker trips when the AC kicks on

What Moves the Price

  • The service call or diagnostic fee
  • Nights, weekends and holidays
  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Whether the equipment sits in a tight attic or on a roof
  • Refrigerant type and how many pounds it takes

We raised the national figures about 41% for Arlington using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

  • Checking refrigerant pressures
  • Clearing the drain line if it's clogged
  • Replacing the failed part
  • Diagnosis and electrical testing
  • A test run

Virginia Licensing and Efficiency Rules

Virginia is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Virginia license or registration number before the visit.

Before You Hire

  • If you see ice, shut the system off. Running it frozen can kill the compressor.
  • Ask for the per-pound refrigerant price before any work starts.
  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
