Your Trusted HVAC Contractor in Chantilly

Chantilly is the Fairfax County side of our service area, the neighborhoods around Poplar Tree Road, Stringfellow Road and Lees Corner Road. We repair air conditioners and gas furnaces here, rework ductwork and zoning, and price out replacements. Our shop is down in Nokesville.

The 1980s built this place. The Census puts about 44 percent of Chantilly's homes in that decade, and three in five went up before 1990. Heat is split almost down the middle. Roughly half the homes burn natural gas and the other half run on electricity, which here usually means a heat pump. So a Chantilly call can mean original 1980s ductwork, a heat pump that has already been replaced once or a gas furnace that's been patched more than once. We figure out which one you have before we quote anything.

Chantilly Neighborhoods We Serve

  • Poplar Tree Estates

    713 single-family homes across four subdivisions: Berkeley Mill, Fox Glen, Hunter Trail and Poplar Tree. The first houses went up in the late 1970s and the last in the early 1990s, between Poplar Tree Road and Stringfellow Road. That spread means one street can have a 45-year-old duct run and the next a 32-year-old one. The HOA has architectural control guidelines, so read them before a condenser changes spots.

  • Armfield Farm

    470 single-family houses between Centreville Road and Lees Corner Road. The Leith and Bokel Drive section, recorded as Armfield Estates, started around 1982. Most of the rest was done by 1994. Any original equipment left here is well past retirement age. If yours still runs, get a replacement price in hand before the next big repair bill.

  • Meadows of Chantilly

    A manufactured-home community near Route 50 and Route 28, built in the 1970s. In communities like this, residents typically own the home and rent the land. Fairfax County's 2025 planning work backs keeping it as housing. Heating and cooling in a manufactured home is its own category, so say so when you call and we'll plan for the tighter space and different parts.

HVAC Challenges in Chantilly

  • Heat pumps in 1980s houses

    Close to half of Chantilly heats with electricity. On a cold night a tired heat pump leans on its backup electric strips, and the bill shows it. If your winter bills jumped and the house still feels cool, have the heat pump checked before you blame the thermostat.

  • Ducts older than the equipment

    Plenty of these houses have had their equipment replaced while the original ductwork stayed put. A new unit on 40-year-old ducts with leaky joints won't deliver what the label promises. Before we size a replacement, we look at the ducts it has to push air through.

  • Townhouses and split levels

    About one in four Chantilly homes is a townhouse. Stacked floors and one thermostat make a hot top floor and a cold lower level. Balancing the ducts helps. Zoning helps more when the gap is big.

Why Chantilly Homeowners Choose a Local Contractor

  • Fairfax permits cover replacements

    Fairfax County requires a mechanical permit for new, replacement, repair or conversion work on an HVAC system. New or replacement ductwork and gas piping for equipment need one too. The county recommends a licensed contractor pull it, and some HVAC jobs also need a residential HVAC certification form. Condos and apartments are handled as commercial buildings under the code, which changes the paperwork.

  • Chantilly mail in two counties

    ZIP 20152 says Chantilly on plenty of envelopes in Loudoun County. Loudoun even lists its Dulles South Public Safety Center at a Chantilly 20152 address. If your house is on that side, Loudoun's permit rules apply, and our South Riding page is the better read.

  • Who your utilities are

    For power, Chantilly homes are on Dominion Energy or NOVEC, which serves parts of Fairfax County. For gas it's Washington Gas or Columbia Gas. Washington Gas itself says Columbia serves some Fairfax areas. Look at your bill. The answer decides which rebates you can use.

  • Rebates right now

    The federal 25C credit ended with work finished by December 31, 2025. Virginia's Home Energy Rebates haven't opened. A Columbia Gas customer can still get $300 to $500 from WarmWise for a gas furnace of 90 percent AFUE or better, while the money lasts. Washington Gas and Dominion customers should ask us what applies before buying.

Chantilly HVAC FAQs

Does Air Force One work in Chantilly?
Yes. We cover ZIPs 20151 and 20152. Give us the street address when you call so we know whether the job falls under Fairfax or Loudoun County.
Do I need a permit to replace my AC or furnace in Fairfax County?
Yes. Fairfax requires a mechanical permit for replacement HVAC work, including new or replacement ducts and gas piping. The county recommends the licensed contractor pull it.
My house has a heat pump. Should I switch to gas?
Maybe, if gas is already at the street and in the house. About half of Chantilly heats each way, so both are normal here. We'll price both options on the same visit and show you the running cost difference.
How much does a repair visit cost?
Repairs start with a $99 diagnostic visit. We find the problem, then give you the repair price before any work starts.
How do I get a price on a new system?
