$8,898 to $23,000 installed for a furnace and air conditioner replaced together, 2 to 5 ton, from the same price book as our estimator. Where you land depends on the size of the house, the efficiency you pick, and what the ductwork and venting need.

What’s different in Burke
Hardly any Burke house still runs the system it was built with. The typical owner-occupied house here went up in 1979: about half predate 1980, nearly all the rest came between 1980 and 1999, and only about 3 in 100 are newer than that. So the furnace and air conditioner in a Burke house are at least the second pair, and the useful question isn’t the age of the house but when the last swap happened, and whether it did both halves at once.
When it did, the two age together. Read the furnace’s rating plate, inside the furnace door, and the label on the side of the outdoor unit. If the dates sit within a year or two of each other and both are past fifteen, that’s a matched pair coming due, and pricing them together is the honest comparison. If the outdoor unit is much younger, the HVAC replacement estimator prices a furnace on its own too.
In Burke the furnace and AC pair is mostly an older-neighborhood job. Around Lake Braddock a little over half the owners heat with gas and about two thirds of the homes are single-family houses, usually with the furnace in a basement or utility room and the condenser on a pad out back. In Burke Centre gas heat is under 3 in 10, and what most of those houses need when the time comes is a heat pump system instead.
For the gas houses inside Burke Centre, the outdoor half is where the Conservancy comes in. A new condenser of the same kind going back in the same spot needs no application. Moving it, or adding a second, does, and the application asks for a plat showing where it goes plus the unit’s dimensions, color, decibel rating and fuel source. Units belong in the rear yard unless the original stood in a side yard, and a side-yard unit can be screened with evergreens or lattice without a separate application.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what that usually means for a replacement.
| Place | Median home built | Most homes are | Heated with | What the system usually is |
|---|---|---|---|---|
| Burke | 1979 | single-family houses, about 6 in 10 | gas, about 6 in 10 | Second or third systems, often on the original ductwork. |
| Burke Centre | 1982 | townhouses, about 5 in 10 | electricity, about 7 in 10 | Mostly electric heat, so usually a heat pump swap instead. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When it’s time
If the furnace plate and the outdoor unit’s label carry the same year, whoever replaced the last system did both at once. The second half to fail is rarely far behind the first, so price the pair when the first one goes.
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.
An older house is usually on its third system, still on ductwork laid out for the first. We check the ducts and venting before sizing the new one.
Permits and sign-offs
Fairfax County lists replacing a heating or cooling system as mechanical permit work. Source.
Fairfax County requires a permit to replace any gas appliance, even like for like: a gas water heater, furnace or boiler. Replacing a fuel-burning appliance also needs a chimney vent certification. Source.
Fairfax County asks for an A2L refrigeration system certification with the permit for any heat pump or air conditioner that runs on the newer A2L refrigerants. Source.

Choosing who installs it
Ask every company that quotes the job, us included.
About half of Burke heats with electricity, so a gas house here has plenty of heat pump neighbors. With gas in the house, a new furnace and AC is one answer and a heat pump system is another. Ask for both numbers before you choose.
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.
Furnace, outdoor unit, matching coil, refrigerant lines, thermostat, permit and hauling the old one away. If it isn’t on the paper, ask.

David and the install team that came over were friendly, knowledgeable and professional. Happy with the install of my Trane system. Tyler was a pleasure to work work with in getting me the best price. He’s got a good thing going over there. I’m glad I went with them!

Questions
Almost certainly not. A furnace and air conditioner from 1979 would be over forty years old, so the pair you have is a replacement, and its own age is the number that matters. The dates on the two labels tell you what you’re pricing.
$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.
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.
