HVAC, Heating & AC Repair in Ashburn, VA
Fast, honest heating, cooling & plumbing for Ashburn — from Brambleton to Ashburn Village — often same-day from our Sterling shop minutes away.
Ashburn’s trusted HVAC, heating & plumbing company
For over 50 years, R.A. Dobson has kept Ashburn homes comfortable through humid Virginia summers and cold Loudoun winters. From the newer builds in Brambleton, Broadlands and Moorefield Station to the established streets of Ashburn Farm, Ashburn Village and Belmont Country Club, our licensed technicians handle heating, cooling and plumbing across every corner of Ashburn — often same day.
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 climb. We help Ashburn homeowners make the honest call between a smart repair and a right-sized replacement, with upfront pricing and no pressure.
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, R.A. Dobson handles it. As a Carrier Factory Authorized Dealer, we install the region’s most reliable equipment and stand behind every job with a workmanship guarantee.

Common Ashburn HVAC & plumbing needs
Ashburn’s homes are mostly master-planned builds from the 1990s onward. Ashburn Village and Ashburn Farm were among the first, so their original heat pumps and furnaces are now prime candidates for high-efficiency replacements, while Broadlands, Brambleton and Moorefield Station bring newer systems that benefit from correct setup and regular maintenance.
Most Ashburn neighborhoods sit under HOA architectural guidelines, so outdoor equipment placement and screening matter. R.A. Dobson helps you replace a condenser or heat pump in a way that keeps your HOA happy and your energy bills down. With the Silver Line’s Ashburn station now open, we also serve the newer condos and townhomes around One Loudoun and Moorefield Station.
Ashburn HVAC & plumbing FAQs
Do you offer same-day service in Ashburn?
Often, yes — we prioritize no-heat and no-cooling calls and reach Ashburn fast from our Sterling shop. Call (703) 481-3700 for the soonest availability.
My Ashburn home’s system is 15–20 years old — repair or replace?
That’s the classic Ashburn question, since so many homes were built in the 1995–2015 boom. We diagnose honestly: if a repair buys you real years, we say so; if the numbers favor a right-sized high-efficiency replacement, we show you the math first.

Yes — R.A. Dobson is fully licensed and insured in Virginia (VA #2701017843) and is a Carrier Factory Authorized Dealer.

Will my new outdoor unit meet Ashburn HOA rules?
Most Ashburn communities have architectural guidelines for outdoor equipment. We help position and screen your condenser or heat pump so it stays compliant while running efficiently.
Is it time to replace my Ashburn Village heat pump?
