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.

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
- Keep two feet clear around the outdoor unit, including snow.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Book maintenance twice a year, once before summer and once before winter.

Heat Pump Repair Questions from Arlington Homeowners
What does heat pump repair cost in Arlington?
Most bills land between $250 and $1,220, including the service call. A typical visit is about $780. Night and weekend calls cost more.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
