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.

Virginia Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in Arlington; the contractor normally pulls it. Before you sign, ask each bidder for their Virginia license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Rinse the indoor filters once a month during heavy use.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
