The labels on both units show the same year
Check the rating plate on the furnace and the one on the side of the outdoor unit. If both read 2001 or 2002, they came with the house, and the first big repair on either is the moment to price the pair.

What’s different in Purcellville
Purcellville grew in two waves, and the newer wave’s systems are wearing out side by side.
Inside the town limits the Census sorts the houses into two big groups. About a third went up from 1980 to 1999, the stretch the Town’s plan describes as larger homes on smaller lots, and about half have gone up since 2000, which puts the median owner home at 2001. The first group is mostly on its second furnace and air conditioner already. In the second, any house that has never had its system replaced is running the pair the builder set the same week the drywall went up.
A builder’s pair ages on one clock. The furnace and the outdoor unit went in together, and at about twenty-five years they tend to give out within a season or two of each other. Pricing both before either fails means the new system gets sized for the house you live in now, finished basement and newer windows included, not the builder’s rule of thumb from 2001.
What counts as the pair depends on the fuel, and Purcellville has three answers. In a propane house it’s a furnace inside and an air conditioner outside, $8,898 to $23,000 installed. In the all-electric houses, close to half the town, it’s a heat pump and air handler, $8,499 to $21,650. And some propane houses run a heat pump in front of the furnace; if that outdoor unit is already on its second round, the furnace alone, $4,285 to $14,040, may be the whole job.
Out on the county side about 96 homes in 100 are detached, many on three to five acres, and close to half went up since 2000. A bigger house out there often splits into two systems, one for the main floors and one for the bedrooms, and each is priced on its own. Only replace the one that’s due.

The Town of Purcellville
Inside the town limits: the downtown grid around Main and 21st Streets, the historic corridors along Main, 21st, 23rd and 32nd Streets and Berlin Turnpike, and the newer neighborhoods such as Village Case.

- Built before 1980about 2 in 10 Census
- Built since 2000about 5 in 10 Census
- Most homes aresingle-family houses, about 7 in 10 Census
- Heated withelectricity, about 5 in 10 Census
- Rentedabout 1 in 10 Census
- A few homes still burn heating oil. We don’t work on oil burners, but a switch to a heat pump or a gas or propane furnace is ours to price.
- Electric heat here usually means a heat pump with backup strips, which is priced as a heat pump system, not a furnace and AC.
When it’s time
When replacing both makes sense in Purcellville.
Your heat may not be a furnace
Where a lot of homes heat with electricity, the indoor half is often an air handler, and the like-for-like swap is a heat pump system, $8,499 to $21,650 installed.
Both halves went in with the house
Plenty of houses built since 2000 still run the builder’s furnace and AC. They wear out on about the same schedule, so when one goes, price the pair.

Choosing who installs it
How to pick who replaces your furnace and AC in Purcellville.
Ask every company that quotes the job, us included.
Did they ask what heats the house before quoting?
In Purcellville a furnace and AC might be a propane furnace, an all-electric heat pump with an air handler, or a heat pump with a propane furnace behind it. Each is a different system with a different price, so a quote written before anyone asks is a guess.
Do they size it to the house, or copy the old label?
The old size is a guess somebody made years ago. Ask whether they measure the house and check the ductwork first. Too big short cycles; too small runs all afternoon in August.
Is the whole job in the written price?
Furnace, outdoor unit, matching coil, refrigerant lines, thermostat, permit and hauling the old one away. If it isn’t on the paper, ask.
Already holding another company’s quote?
Our free second opinion looks at the system you were quoted on and tells you what it actually needs, with our price if you want it.

Questions
Furnace and AC replacement questions from Purcellville.
Does a new propane furnace inside the town limits need a permit?
Yes, a Loudoun County one, even when the new furnace goes in the old one’s spot, because propane is a fuel gas. Since October 2025 the County skips plan review when the BTUs and the spot stay the same, which keeps a straight swap simple.
We’re on propane. Should the new system stay propane?
It can go three ways: a propane furnace with an air conditioner, an all-electric heat pump system, or a heat pump with a propane furnace as backup. The HVAC replacement estimator prices the choices for your house.
How much does a new furnace and AC cost in Purcellville?
$8,898 to $23,000 installed for the pair, by size and efficiency. A furnace alone, keeping your AC, is $4,285 to $14,040. The HVAC replacement estimator gives your house its own number.
Do I have to replace both at the same time?
No. If the AC is young and only the furnace failed, replace the furnace. If they’re the same age, do both: a new outdoor unit needs a matched coil, and one built for the old refrigerant isn’t rated for the new one.
