Furnace Installation & Replacement in Northern Virginia
Golden Arrow Service installs and replaces gas, electric, and oil furnaces across Northern Virginia, from Fairfax and Loudoun County to every community in between — checking your ductwork, sizing, and permit needs before we quote, not after. A furnace nearing fifteen years old, or one that’s needed three repairs in two winters, is usually past the point where another repair makes sense, and we’ll tell you honestly which side of that line your system is on. We’ve done this as a family-owned company since 1999, with the same licensed technician evaluating and installing your furnace. If your furnace has already failed, we prioritize no‑heat calls and get a technician out as soon as possible instead of leaving you waiting in the cold.

Types of Furnaces We Install in Northern Virginia
Not every home needs the same furnace, and older Northern Virginia houses often have ductwork and mechanical spaces that rule out a one‑size‑fits‑all approach.
We install and replace:
- Gas furnaces (standard and high‑efficiency)
- Electric furnaces
- Oil furnaces, including oil‑to‑gas conversions
- Standard, two‑stage, and variable‑speed models
- 80% AFUE and high‑efficiency condensing furnaces (95%+ AFUE)
If you’re not sure what you have now, we identify it during the walkthrough and match the new system to your home’s layout, ductwork, and fuel source.
Repair or Replace Your Furnace in Northern Virginia: Signs That Matter
Most furnace replacement calls we get in Northern Virginia follow the same pattern.
- Three or more repairs in two winters — costs add up faster than most homeowners expect, especially once repairs reach the heat exchanger or blower motor.
- A system past fifteen years old — most furnaces are built for a 15–20 year lifespan; efficiency drops well before anything technically “breaks.”
- A heating bill that keeps climbing — with nothing else changed at home, that usually means the unit is working harder for the same heat.
A single failed igniter is often still a fair furnace repair, not a reason to replace. We look at your system’s actual history before recommending either.
Furnace Replacement Demand Across Northern Virginia
Vienna is home base, but the furnace replacement calls we get run heaviest out of McLean and Fairfax County, where many homes still run original systems installed decades before current efficiency standards existed. Older housing stock in this part of Northern Virginia means replacement jobs here often involve tighter mechanical closets or older ductwork that a newer furnace has to work around, not just a straight swap. Areas like Reston and Loudoun County see the same pattern as homes there reach the same age.
Wherever you’re located, we size the job to your actual house, not a generic install.

- The technician who diagnoses the problem is the one who fixes it, without handing you off to someone else for the repair.
Furnace Installation Cost & Factors in Northern Virginia
What a new furnace costs depends on more than the unit itself — fuel type, AFUE efficiency rating, and how much of your existing ductwork can be reused all factor in. A gas furnace typically costs less to install than switching fuel types entirely, since the gas line and venting are often already in place. Higher‑AFUE units cost more upfront but lower monthly bills over the system’s life, which matters more in older Northern Virginia homes running less efficient equipment.
After a walkthrough, we give you a clear written quote based on your home’s actual setup — not a phone estimate that changes once we arrive. Flexible financing is available on request, so a full system replacement doesn’t have to wait on your budget.
Oil-to-Gas Conversion in Northern Virginia
Homes still running oil furnaces are common in older parts of Northern Virginia, and converting to gas is one of the least‑covered jobs in this market — most contractors quote it like a straight furnace swap, then the project stalls once the oil tank needs removal, a new gas line has to be run from the street, and Dominion Energy has to confirm service to the property.
We coordinate that utility connection and the oil tank decommissioning before your installation date is set, not after work has already started. Electric‑to‑gas conversions follow a similar path, minus the tank removal.
Converting from oil or electric? Call Us— we’ll map out what your property actually needs first.
Furnace Installation Permits in Northern Virginia
Fairfax County splits furnace permits into two tracks, and knowing which one applies saves you a scheduling headache. A straight, like‑for‑like swap — same fuel type, same ductwork, no layout changes — falls under the Household Appliance Permit (HAPL), which closes with a single final inspection. Anything bigger — new ductwork, a fuel conversion, or a system that isn’t a direct replacement — requires the more involved Mechanical Permit (MECHR).
Loudoun County runs its own process: most installations and replacements need a mechanical permit filed through the county’s building department portal, separate from Fairfax’s system. We pull the correct permit before work starts in Fairfax County and Loudoun alike, so nothing holds up your install day.
Furnace Sizing & High-Efficiency AFUE Ratings for Northern Virginia Homes
The AFUE rating on a furnace only matters if the unit is sized right first — an oversized 96% AFUE furnace still short‑cycles, wastes fuel, and wears out early. We run a Manual J load calculation on every install instead of matching the tonnage on your old unit, since additions, insulation upgrades, or new windows since your last furnace can change what your home actually needs.
Standard 80% AFUE furnaces vent through a traditional metal flue; 95%+ AFUE condensing furnaces recover more heat but need PVC venting and a condensate drain, which not every mechanical room is set up for without extra work. We’ll tell you plainly which tier fits your house and your venting, not just which one carries the bigger margin.

Furnace Install Day Process for Northern Virginia Homes
A furnace swap follows the same sequence in every home, though what’s behind the walls changes the details.
- Protect and remove. We protect the path to your mechanical room, then disconnect and pull the old furnace — ductwork, gas or oil line, and venting come out with it.
- Set to spec. The new unit goes in at manufacturer‑rated clearances with a sealed plenum, plus any new gas line or vent liner the job needs — not a generic swap.
- Test, not just power on. Combustion analysis, static pressure, and a carbon monoxide check at the unit before the crew leaves.
- Walk through and close out. We review the thermostat with you, and schedule any required county inspection ourselves.
