Herndon’s Go-To HVAC & Plumbing Team
Much of Herndon was built out between the 1970s and 1990s, and a large share of its townhomes run on compact heat pumps that are now well past their prime. These systems work hard in Virginia’s swing seasons, and when they fail, homeowners need a company that can diagnose a heat pump correctly — not just condemn it. We repair what’s worth repairing and replace only when the numbers truly say so.
Neighborhoods we serve in Herndon: Kingstream, Chandon, Dulles Park, Franklin Farm, McNair, Fox Mill, Reflection Lake and Sugarland Run — plus the townhome and single-family communities along Elden Street and the Fairfax County Parkway.
Whether it’s a townhome heat pump, a single-family furnace, a water heater or a spring maintenance visit, R.A. Dobson handles it with upfront pricing and clean, respectful work. As a Carrier Factory Authorized Dealer, we stand behind every installation and repair.
