Your Trusted HVAC Contractor in Warrenton

Warrenton calls reach us from all three ZIPs, 20186, 20187 and 20188. This page is about the Town of Warrenton itself: Old Town, the streets inside the bypass and the town's own permit and historic rules. Here we fix air conditioners, replace worn-out systems, rework ducts and zoning, swap water heaters and do seasonal tune-ups. If your 20187 address sits out along Route 29 in Brookside or Vint Hill, our New Baltimore page fits you better.

Warrenton's houses are older than most of what we see in Prince William. About one in six homes in town was built in 1939 or earlier, and another one in five went up between 1940 and 1979. Only about one in twenty is newer than 2010. Heat is close to an even split. Almost half of households burn natural gas and a little over four in ten heat with electricity. A small share still runs on heating oil. Half the homes are detached houses, about one in five is a townhouse and most of the rest are apartments or condos.

Warrenton Neighborhoods We Serve

  • Old Town and the Historic District

    The town's historic district centers on the downtown business blocks and the five residential neighborhoods around them, with the courthouse at the middle. Exterior changes here need a Certificate of Appropriateness before work starts, and the design guidelines list HVAC units by name. Window units on houses are the exception.

  • Falmouth Street

    Most houses on Falmouth Street between Lee Street and Public Works Drive date from around 1900, and the town counts about 60% of them as Craftsman-style. Nobody built these for central air. Ductwork got added later, sometimes more than once, so we trace where it actually runs before we size anything new. The street sits inside the historic district.

  • Foxcroft

    Foxcroft is one-story ranch houses on big lots around Rady Park. In a ranch, every duct lives in the attic or the crawlspace. When the bedroom at the end of the hall won't cool, that's where we look first.

  • Olde Gold Cup

    The biggest subdivision in town. Hundreds of single-family homes went up here in the 2000s, and the town's housing study puts the average size of that building wave at over 4,500 square feet. A house that size often runs two systems. Original equipment from that era is now roughly 17 to 25 years old, which is when repair bills start to argue for a replacement quote.

HVAC Challenges in Warrenton

  • Century-old houses with add-on ducts

    With one home in six built before 1940, a lot of Warrenton ductwork was squeezed into houses after the fact. Undersized returns and long runs are common. A bigger unit won't fix that, so we check the ducts before we quote equipment.

  • Townhouses and condos

    About one in five town homes is attached and roughly one in six sits in a building with five or more units. Condenser spots are tight and often set by an association. Tell us where the air handler is, attic, closet or utility room, when you call.

  • The 2000s equipment wave

    Nearly a quarter of the town's homes were built between 2000 and 2009. Plenty of those furnaces, air handlers and condensers are still original. We get a lot of calls where a big repair on one of them is really a question about replacement.

Why Warrenton Homeowners Choose a Local Contractor

  • The town issues your permit

    Inside town limits, the Town of Warrenton issues building permits, not the county. Its list of work that needs one includes any change to a home's HVAC (mechanical) system and any replacement of a gas or oil furnace. Outside town limits, Fauquier County handles it.

  • Where the condenser can sit in the Historic District

    The town's design guidelines want ground-mounted equipment at the rear of the building and screened with a wall, fence or planting. Visible refrigerant lines should be painted or covered to match the house. Duct and pipe runs belong inside closets and wall cavities, off the front of the building. Some reviews go to staff and some go to the Architectural Review Board, and approval comes before the permit.

  • Who supplies your gas and power

    Columbia Gas of Virginia is the natural gas utility in Fauquier County. Electric service in the county comes from Dominion Energy, NOVEC or Rappahannock Electric Cooperative, and it can change from one road to the next. Your bill tells you which one you have.

  • Rebates worth checking

    Columbia Gas runs WarmWise rebates on new gas furnaces: $300 for 90% AFUE, $400 for 95% and $500 for 97%, while funding lasts. The federal 25C tax credit only covered work finished by December 31, 2025. Virginia's Home Energy Rebates aren't open yet.

Warrenton HVAC FAQs

Do I need a permit to replace my furnace in town?
Yes. The Town of Warrenton lists gas and oil furnace replacement and HVAC system changes among the work that needs a building permit. We pull it as part of the job.
I'm in the Historic District. Can the new condenser go where the old one was?
Often, but it still needs a Certificate of Appropriateness, because HVAC units are on the town's review list. A spot at the back of the house, screened from the street, is what the guidelines ask for.
My mail says Warrenton 20187. Am I in town?
Maybe not. More than half the homes in 20187 are in the New Baltimore census area, which covers Brookside and Vint Hill, and those permits go through Fauquier County.
What does a repair visit cost?
Repairs start with a $99 diagnostic visit. If you're thinking about a new system, start with our free instant estimate online and we'll follow up with a free in-home estimate.
Is there a rebate for a new gas furnace?
If Columbia Gas is your gas company, WarmWise pays $300 to $500 depending on efficiency, while funding lasts. The federal 25C credit ended with 2025 work.
