HVAC, Heating & AC Repair in Ashburn, VA

Ashburn grew up fast. Much of its housing stock went up during the 1995–2015 boom, which means a large share of homes are now running first-generation air conditioners, furnaces and heat pumps that are 15–25 years old — right at the age when efficiency drops and repair bills start to climb. We help Ashburn homeowners make the honest call between a smart repair and a right-sized replacement, with upfront pricing and no pressure.

Neighborhoods we serve in Ashburn: Ashburn Village, Ashburn Farm, Brambleton, Broadlands, Belmont Country Club, Loudoun Valley Estates, Moorefield Station, One Loudoun, Goose Creek Village, Farmwell Hunt and Windmill Parc — plus the surrounding communities along the Loudoun County Parkway and Waxpool Road corridors.

Whether it’s an AC that quit during a July heat wave, a furnace that won’t fire in January, a failing water heater or a spring tune-up before the season turns, R.A. Dobson handles it. As a Carrier Factory Authorized Dealer, we install and service the region’s most reliable equipment — and we stand behind every job with a workmanship guarantee.
