Written October 2026, with Prince William County’s permit pages, the Census and every review platform read the same month.
A new furnace and air conditioner in Woodbridge runs $8,898 to $23,000 installed, depending on the size of the house and the equipment you pick. From about $148 a month at 0% APR for 60 months, the whole price financed, on approved credit. That’s our Northern Virginia price book, posted on our Woodbridge furnace and AC page before anyone comes out.
Woodbridge is one of the busiest towns on our schedule, and more of our Woodbridge calls end in a full system replacement than in most towns we serve. So this guide is mostly about that: when to repair and when to replace, what decides the price, the permit Prince William County wants (and the swaps it doesn’t), and what to check about any company before it touches your system.

In Woodbridge most weekdays
Our shop is on Lafayette Center Drive in Chantilly. Our crews spend their days out across Northern Virginia, and Woodbridge gets a lot of those days: our heating and cooling team is there most weekdays, in all three Woodbridge ZIP codes, 22191, 22192 and 22193, from Leesylvania and Potomac Mills to Lake Ridge and Dale City. The work is done by our own HVAC team, separate from our plumbers.
Each service we do in Woodbridge has its own page, and every one opens with the price: furnace and AC replacement, furnace replacement, heat pump replacement, AC replacement, AC repair and furnace repair. The rest is on our Woodbridge page.
Repair or replace, in a Woodbridge house
Across Woodbridge, Lake Ridge and Dale City it’s mostly houses: nearly half of the homes are detached and more than a quarter are townhouses, with condos and apartments about one in six. About two in three went up between 1960 and 1999. Gas heats more than half of owner-occupied homes, with about four in ten on electricity (Census: homes by type, year built, heating fuel).
The rule we use on a repair call: under about eight years old, repair almost anything. Past about fourteen, a compressor, a heat exchanger or a reversing valve is replacement money, and that’s the time to put a replacement price beside the repair price before you decide. In between, it depends on the part and the shape of the rest of the system. Repair vs replace your AC has the longer version.
Our Woodbridge heating repair guide goes ZIP code by ZIP code, with what each repair costs.
What a new system costs in Woodbridge
Installed prices from our price book for 2 to 5 ton systems, the same numbers our HVAC estimator works from. The size of the house, the efficiency you pick, and what the ductwork and venting need decide where you land.
| The job | Installed | Or monthly |
|---|---|---|
| Furnace and AC replaced together | $8,898 to $23,000 | $148/mo at 0% APR for 60 months |
| Furnace alone, keeping your AC | $4,285 to $14,040 | $71/mo at 0% APR for 60 months |
| Heat pump system | $8,499 to $21,650 | $142/mo at 0% APR for 60 months |
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.
The estimator gives your house its own number in about two minutes. Then one of our technicians measures, and the price is in writing before anything is ordered. Two years of our labor come with every install, and five or ten are available. Here’s how financing works.
Our reviews, low ones included
Counted across every platform we’re on, we’re rated 5.0 stars across 1,132 reviews on Google, Angi, Yelp, the BBB and Facebook. The lowest of them is Yelp, at 4.4 stars, about one in twenty of the total, and it’s in the count on purpose. A number that leaves out the hard site isn’t the whole number.
Each platform’s rating, its count and the date it was read are at swiftproreviews.com, and the reviews themselves are on our reviews page. Read the low ones before you decide.
What to check about any Woodbridge HVAC company
- The license. Look the company up on DPOR’s License Lookup. The name should match your estimate, the license should be active, and it should cover HVAC. Ours is Virginia Class A 2705192276, printed on the side of our vans.
- The permit. Woodbridge is in Prince William County, and the County’s rule splits by fuel: replacing a gas furnace always takes a permit, while swapping a heat pump, an electric furnace or an air conditioner’s outdoor unit for the same type in the same spot doesn’t, and neither does a repair with replacement parts. Moving equipment, an upgrade that needs electrical, plumbing or mechanical changes, or any alteration to the heating and cooling system takes one. The permit holder is responsible for the work, so ask whose name goes on it.
- Every line in writing. The AC or heat pump’s size in tons and its SEER2 rating, the furnace’s size and efficiency, the coil, the thermostat, the permit, hauling the old equipment away, and the years of labor. A lower total that leaves off the coil or the permit isn’t lower. How to read an HVAC replacement estimate goes line by line.
- Reviews on every platform, not one site’s worth. Our HVAC contractor guide covers the rest, including insurance and the written contract.
