What it costs
The same price book our estimator runs on, for a central air conditioner on its own, keeping the furnace you have. A single-stage unit on a small house sits near the bottom; a variable-speed one on a big house, near the top.

Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
The HVAC replacement cost estimator narrows it to your house. Then a tech measures, and you get the installed price in writing before anything is ordered.
With Comfort+ membership at $199 a year, the diagnostic visit is included, and half of each repair bill is banked toward replacing that system, up to $1,500.
What’s different in Nokesville
Electricity heats 1,695 of the 3,076 owner homes in 20181, and out here that mostly means a heat pump, one outdoor unit for summer and winter, so its replacement belongs on the heat pump page. The AC-only houses are the fuel-burning ones: 597 on propane and 459 on gas, a furnace inside with a separate condenser outside. If the condenser wears out before the furnace, only the outdoor unit and the coil above the furnace get replaced.
Nokesville built in two waves, and its condensers sort the same way. The 1970s and 80s added 1,238 homes, now on their second air conditioner or later. The 2000s added 904 more, many still cooling with the builder’s condenser, between 17 and 26 years in, and one installed before 2010 most likely runs R-22. The 401 homes finished since 2010 came with R-410A or newer, still serviced, so a breakdown there gets a repair price before anybody quotes a replacement.
The village is older. In the Census place around Aden Road the median owner home dates to 1970, and close to four in ten homes went up before 1960, when central air wasn’t standard. There the cooling came later, through ductwork added in an attic or crawlspace or squeezed onto the old heating ducts. Before a new AC goes on, the tech checks whether those ducts and the return can carry the air a new coil needs.
Prince William County’s guidelines for replacing mechanical equipment without plan review want the new unit on the same fuel, at the same capacity, in the same spot. Size the new AC to the rooms and it may not match the old capacity, so ask how that changes the paperwork before you sign. On a big lot the old pad is usually still the right place, and there’s no town office in Nokesville layered on top of the county’s.

When it’s time
A house finished here between 2000 and 2009 may still cool with the condenser its builder set. If that unit was made before 2010, it likely holds R-22, so a leak means reclaimed refrigerant. With a sound propane or gas furnace inside, a new AC alone is the sensible fix.
An air conditioner put in before 2010 most likely holds R-22, which hasn’t been made since 2020. A leak on one of those usually ends the repair road.
A house from the 2000s often cools with the condenser it was built with. Past fifteen years, compressors and fan motors start to go, one after another.
Permits, locally
Prince William County lists any work that alters a home’s heating and air conditioning as permit work, but swapping an electric furnace, heat pump or air conditioning condensing unit for the same type of unit in the same spot is an ordinary repair that needs no permit. Source.

Choosing who installs it
Questions to ask anybody who quotes you, us included.
An older village house may run the well pump, the furnace blower and the outdoor unit off one panel sized decades ago. The new condenser’s nameplate sets the breaker and wire it needs, so ask whether the quote checked that against your panel and said what it found.
Ask how they picked the size. Copying the old nameplate repeats whatever was guessed when the house was built.
The outdoor unit and the coil on the furnace are rated as a pair. Ask whether the quote replaces both, and what happens to the line set.
A good company puts the repair price next to the replacement range and lets you choose. Already holding somebody’s big number? Take the free second opinion first.

Questions
Not quite: your outdoor unit is doing double duty, so it gets priced as a heat pump at $8,499 to $21,650, and the propane furnace keeps its job as backup. This page fits the Nokesville houses whose furnace carries all the heat while the condenser rests until May.
Not automatically. Of the 3,440 homes in 20181, 2,071 count nine or more rooms, and a house that size often splits its cooling between two systems, basement and attic, each priced on its own. The tech measures the rooms each one serves, and the right size can come out smaller than the old label.
$5,942 to $14,450 installed for a central air conditioner on its own, keeping the furnace you have; size and efficiency set where yours lands. An AC and furnace together run $8,898 to $23,000. The HVAC replacement cost estimator gives your house its own number.
It’s worth pricing. A heat pump cools exactly like an AC and also heats on mild days, so with your gas furnace it becomes dual fuel. A heat pump system runs $8,499 to $21,650 installed, and we’ll price it both ways.
Ready when you are
Call, or send the form at the top. A tech measures the house and puts the installed price in writing before anything is ordered, and if the old AC is worth fixing, you’ll hear that first.
