Written October 2026, with Fairfax County’s permit pages, the Census and every review platform read the same week.
A new furnace and air conditioner in Centreville 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. It’s the same Northern Virginia price book we use everywhere, posted on our Centreville furnace and AC page before anyone comes out.
Centreville is practically next door: our shop in Chantilly is about five miles away, and Centreville is one of the towns we work in most. Below: what a Centreville house usually has (very often, a townhouse), what a new system costs, the permit Fairfax County wants, and how to check any company before it starts.

Five miles from our shop
Our shop is on Lafayette Center Drive in Chantilly, about five miles from Centreville, down Route 28. We cover both Centreville ZIP codes, 20120 and 20121, with our own heating and cooling team, a crew separate from our plumbers, and Centreville is one of the towns we’re in most.
Next door runs on the same price book: the Herndon guide and the Reston guide cover those towns the same way.
Each service we do in Centreville has its own page, and every one opens with the price: furnace and AC replacement, furnace replacement, heat pump replacement, AC repair and furnace repair. The rest is on our Centreville page.
Townhouse country
Almost half Centreville homes are townhouses, more than any other kind, and about three in ten are detached houses. About seven in ten went up between 1980 and 1999, and the median owner’s home dates from 1990. Gas leads the heating: about three in four owner-occupied homes heat with it, and about a quarter with electricity, which here almost always means a heat pump (Census: homes by type, year built, median year, heating fuel).
A townhouse changes the job more than the price. The furnace often shares a small utility room with the water heater, the outdoor unit sits on a pad out back or in a narrow side yard, and the new system has to fit the room and the way in. We look at all of it on the visit, and anything beyond a standard swap goes on the estimate as its own line with its own price. If your system is acting up rather than done, our Centreville heating repair guide covers what fails and what each repair costs.
What a new system costs in Centreville
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, every site in the count
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. Yelp is the lowest, at 4.4 stars and about one in twenty of the total, and we count it with the rest rather than leave it out.
Each platform’s rating and count, with the date it was read, is at swiftproreviews.com, and the reviews themselves are on our reviews page, low ones included.
What to check about any Centreville 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. Centreville is in Fairfax County, which requires a mechanical permit to replace a heating or cooling system, and a gas furnace needs one even when it’s like for like. The county recommends the licensed contractor pull it, as the responsible party.
- 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.
Centreville HVAC questions, answered straight
Does SwiftPro serve Centreville, VA?
Yes. Our shop is in Chantilly, about five miles away, and Centreville is one of the towns we work in most. We cover 20120 and 20121 with our own heating and cooling team. Our Centreville page lists every service with its price.
How much does a new HVAC system cost in Centreville?
A furnace and air conditioner replaced together runs $8,898 to $23,000 installed. A furnace alone runs $4,285 to $14,040, and a heat pump system $8,499 to $21,650. From about $148 a month at 0% APR for 60 months, the whole price financed, on approved credit. Where you land depends on the size of the house, the efficiency you pick, and the ductwork and venting.
Does a townhouse HVAC replacement cost less?
Usually the system is smaller, which keeps it toward the lower end of the range, but the price follows the size and the equipment, not the kind of house. Tight utility rooms and outdoor units in narrow side yards can add work, and anything like that goes on the estimate as its own line.
Do I need a permit to replace my HVAC in Centreville?
Yes. Centreville is in Fairfax County, which requires a mechanical permit to replace a heating or cooling system, and a gas furnace needs one even when it’s like for like. Have the contractor pull it in its own name.
Why is SwiftPro’s Yelp rating lower than its Google rating?
Yelp is a small slice of our reviews, about one in twenty, and it filters hard. It’s our lowest score at 4.4, and we count it in our total anyway. Every platform’s number and the date it was read are on our reviews page.
Is SwiftPro licensed and insured?
Yes. Virginia Class A contractor license 2705192276, licensed and insured, BBB Accredited with an A rating. We’re a Trane Comfort Specialist, Carrier experts, a Rheem Pro Partner and a Mitsubishi Electric Diamond Contractor.
Can I pay for a new system monthly?
Yes, on approved credit. From about $148 a month at 0% APR for 60 months, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. Here’s how financing works.
Who is the best HVAC company in Centreville?
The one that shows you its price, its license and every review before it comes out, and pulls the permit in its own name. A company down the road and one five miles away should both pass the four checks above. Run them on anyone, us included.
