Your Trusted HVAC Contractor in Haymarket

Haymarket 20169 is one of our busier ZIPs, and most of it is cooling work and system replacements.

Housing in 20169 is new. About a quarter of the homes were built after 2010 and nearly half in the 2000s. Close to two in three heat with natural gas and about a quarter with electricity. The last tenth is mostly propane and fuel oil. New doesn't mean new equipment, though. A system from 2003 is past 20.

Haymarket Neighborhoods We Serve

  • Dominion Valley Country Club

    Toll Brothers started Dominion Valley in the early 2000s and was still adding townhomes in 2024. It's 2,467 homes, detached and attached, most of them behind one of eight gates. Tell us which gate to use. Systems here run from a couple of years old to well past 20, so we look before we guess.

  • Regency at Dominion Valley

    The 55+ section of Dominion Valley (Toll Brothers again): 958 homes, with 533 single-family, 199 attached and 226 condos. Condo owners should check with the association before work that touches shared space.

  • Piedmont

    1,619 homes in three parts: gated Piedmont, Old Carolina Estates and the Piedmont Riding Club. It sits near I-66 and Route 15 around a Tom Fazio golf course. The gated section has two staffed gates, so pass along your visitor instructions when you call.

  • The Town of Haymarket

    The incorporated town is small. The whole thing has been a historic district since 1994, and a house built before 1950 counts as a historic building. Those are the homes where any visible change to the outside gets a close look.

HVAC Challenges in Haymarket

  • AC that can't keep up in July

    A lot of our Haymarket calls are cooling calls. Larger homes here often run a separate system for the top floor, and that one works hardest. Dirty coils, refrigerant leaks and dead capacitors are the usual finds.

  • Oil and propane in older homes

    About 4 percent of 20169 homes still burn fuel oil and about 6 percent use propane. If you're on oil, a switch to a heat pump or gas is worth pricing when the furnace or boiler gets old. Replacing an oil or gas furnace needs a county permit either way.

  • Big houses, uneven rooms

    Large open floor plans and finished basements are common here. Rooms far from the air handler run warm or cold. Balancing the ducts or adding zoning often fixes it for less than a new system.

Why Haymarket Homeowners Choose a Local Contractor

  • Town address or county address

    A Haymarket mailing address doesn't put you inside the town. Dominion Valley, for one, sits a mile or two outside it. Inside town limits there's one extra step. The town gives zoning approval first and then Prince William County issues the permit. The county has handled town building permits since January 2018.

  • Historic district rules for condensers

    The town's design guidelines say outdoor heating and AC units have to be screened from public view with a wall, fence or year-round plantings. Changes in the historic district need a certificate of appropriateness from the Architectural Review Board, which meets the third Wednesday of each month. If your new condenser goes somewhere visible, plan for that meeting.

  • Utilities

    Toll Brothers' Dominion Valley area guide lists NOVEC for power and Washington Gas for gas. Other parts of 20169 can be on Dominion Energy or Columbia Gas of Virginia. Your bill settles it. Columbia customers can get $300 to $500 back on a high-efficiency gas furnace while WarmWise funding lasts.

  • HOA gates and approvals

    Same-spot condenser swaps are simple. Moving a unit or adding one is when you want the HOA paperwork done first.

Haymarket HVAC FAQs

Do I need town approval to replace my AC?
Only if you're inside the Town of Haymarket. Then you need town zoning approval before the county permit, and a visible unit in the historic district needs a certificate of appropriateness and screening. In Dominion Valley or Piedmont, your HOA is the one to check.
Do you service Dominion Valley and Piedmont?
Both, regularly. Give us your gate details when you call.
Can you replace an oil furnace?
We can. Ask for a new-system estimate and we'll price it against a heat pump, or a gas furnace if gas runs on your street. New-system requests get a free in-home estimate.
How fast can you get here?
We respond right away. Call and Sara, our assistant, can take the details if the team is on a job.
