Heating Installation in Northern Virginia: Furnace, Heat Pump & Boiler

A furnace, heat pump, and boiler each heat a Northern Virginia home differently — through ductwork, refrigerant, or circulating hot water — and the right one depends on what’s already in your house, not just which system costs less upfront. Golden Arrow Service walks homeowners through that decision during an in-home evaluation, then handles whichever heat pump installation or furnace installation fits, with permits pulled in Fairfax and Loudoun County alike.Call (703) 782-5028 to schedule your free heating system evaluation.

Which Heating System Fits Your Northern Virginia Home

Which system makes sense starts with what’s already running your house, not which one sounds newest. A furnace heats air and pushes it through ductwork — the straightforward choice if your home already has ducts in good shape. A heat pump moves heat instead of burning fuel, so it heats and cools from one system, and works well both with existing ductwork and in additions or rooms that never had ducts. A boiler heats water instead of air, circulating it through radiators or baseboards — still common in Northern Virginia’s older homes built before forced-air heating became standard, where the piping is already there and adding ductwork would mean opening finished walls.

During your evaluation, a Golden Arrow technician looks at what’s already distributing heat in your home, your fuel access, and your home’s age and layout before recommending anything — not just quoting whichever system is easiest to sell.

Why Northern Virginia Homeowners Trust Golden Arrow for Heating Installation

What Affects the Cost of a New Heating System

Cost comparisons across furnace, heat pump, and boiler systems rarely land where homeowners expect, because the equipment price is only part of it. A heat pump typically costs more to install than a straight furnace swap, but it replaces your air conditioner’s job too, so comparing the two on equipment price alone skips half the math. A boiler replacement can run higher or lower than switching to a furnace, depending entirely on whether the existing piping and radiators are reusable or need rework — there’s no fixed rule either way. Efficiency tier adds another layer: higher-efficiency equipment costs more to install across every category, and whether that trade-off pays off depends on how long you’re staying in the house.

Because the honest number depends on your ductwork, piping, and how many zones your home needs, every job gets sized and quoted after we’ve actually seen it — not estimated from a category average.

Permits for a New Heating System in Fairfax & Loudoun County

A new heating system almost always needs a permit before the county signs off, and which one depends on where you live and what’s changing.

Fairfax County — a straight equipment swap (same fuel, same ductwork) usually qualifies for the simpler household appliance permit; a fuel conversion, new ductwork, or a different system entirely needs the more involved mechanical permit instead, which we break down in full on our furnace installation page.
Loudoun County — runs its own process through the county’s building department portal, and most new heating installations need a mechanical permit filed there before work begins.

We pull whichever permit your job needs before your install date is set, in either county.

Rebates & Tax Credits for a New Heating System in Northern Virginia

The federal tax credit that used to cover heat pumps and other efficient equipment — Section 25C — expired for anything placed in service after December 31, 2025, according to the IRS’s own guidance. If you’re installing in 2026, that credit no longer applies, whatever an older article or a competitor’s page might still claim.

What’s still active is different: Dominion Energy and Virginia’s statewide efficiency programs continue to offer rebates on qualifying heat pump installations, though a standalone gas furnace or boiler swap typically doesn’t qualify the same way. Eligibility and rebate amounts change often enough that we check the current program details against your specific equipment before you install, rather than quote a number that might already be out of date by the time you call.

Financing a New Heating System

Whichever system ends up being the right fit — furnace, heat pump, or boiler — financing comes up during the same evaluation visit, not as an afterthought once you’ve already picked equipment. That matters most when a system fails outright in the middle of a cold snap: financing means a decision made under pressure doesn’t also have to be a decision made without options.

New Heating System FAQs

How do I know I need a new heating system instead of another repair?

Multiple repairs in the same winter, a system fifteen years or older, or heating bills that keep climbing with nothing else changed at home are worth having evaluated. A single component failure on a younger system is usually still a fair repair, not a reason to replace.

Is a boiler or furnace better for an older Northern Virginia home?

It depends on what's already there more than the home's age alone. A home with existing radiators or baseboards and no ductwork usually stays with a boiler, since adding ducts later means opening finished walls — a home with old but usable ductwork is often a more straightforward furnace or heat pump swap instead.

How long does it take to get a new heating system installed once I decide?

It depends on your system and whether ductwork, piping, or venting changes are needed. We give you a specific timeline during your evaluation, not a generic estimate that doesn't account for your home.

Can I switch from one heating system type to another, like a furnace to heat pump?

Yes. Switching from a furnace to a heat pump, or from a boiler to a ducted system, is possible, but it usually means confirming your ductwork, electrical capacity, and fuel access can support the new equipment — exactly what an in-home evaluation checks.
