HVAC, Heating & AC Repair in Chantilly, VA
Zoned systems, heat pumps and high-efficiency furnaces for Chantilly’s larger homes — balanced properly, priced honestly.
Chantilly’s reliable HVAC & plumbing company
For over 50 years, R.A. Dobson has kept Chantilly homes comfortable through every Virginia season. From the established communities of Greenbriar and Poplar Tree to the newer single-family homes near South Riding and the Route 50 corridor, our technicians service heating, cooling and plumbing throughout western Fairfax County.
Chantilly’s larger, newer single-family homes often run two-zone or two-system setups — and when one stops keeping up, comfort and energy bills both suffer. We’re experienced with zoned systems, heat pumps and high-efficiency furnaces, and we take the time to balance a home properly rather than just swapping a part and leaving.
Whether it’s a struggling zone, a failed AC unit, a water heater or a preventative tune-up, R.A. Dobson delivers honest, high-quality work. As a Carrier Factory Authorized Dealer, we install premium equipment sized right for your home and back it with our workmanship guarantee.

Common Chantilly HVAC & plumbing needs
Chantilly homes run larger than the county average — many with two-story great rooms, finished basements and multiple zones. Subdivisions like Greenbriar, Little Rocky Run and Rocky Run were built from the 1980s through the 2000s, so systems there are commonly at or near replacement age, and bigger homes often need dual or zoned HVAC to heat and cool evenly.
Toward western Chantilly and Pleasant Valley, homes sit on larger lots that frequently run on well water and septic, which changes how we approach plumbing and water heaters. R.A. Dobson has served Chantilly since 1975 and handles it all — from a zoned system balancing a two-story great room to a well pump or water heater on a rural property.
