Quick answers: Phoenixville furnace replacement cost
In 2026, most Phoenixville homeowners pay between $5,500 and $14,000 for a new furnace installed: $5,500–$7,500 for single-speed, $8,000–$12,000 for two-speed, and $13,000–$14,000 for variable-speed. But that's just the equipment. Your final number is the tier you choose plus what your specific home's install takes, which in Phoenixville depends a lot on whether you're in a newer townhome, a historic-district Victorian, or an older Borough Core rowhome. Your exact price is set after a free in-home assessment.
When you move from an older 80% furnace to a high-efficiency 90%+ model, the new furnace vents out a sidewall in PVC and can no longer use the old masonry chimney. In many older Phoenixville homes, that same chimney also vented the water heater, so once the furnace comes off it, the water heater is left on an oversized flue and often needs a liner to vent safely. It's a common, legitimate line item on older homes, and it's one a suspiciously cheap quote tends to leave out.
Usually only if the work changes something visible from the street. Phoenixville's Historical Architectural Review Board (HARB) reviews exterior changes visible from a public way inside the Downtown Historic District. Your furnace itself is invisible, but a new sidewall vent on a street-facing wall can trigger a review. On a rear or side wall out of public view, it typically won't. A good installer plans the venting with this in mind.
Chester County has one of the region's higher shares of propane heating, so this comes up often around Phoenixville. If natural gas is available on your street, a furnace replacement is the most cost-effective time to convert, because much of the labor overlaps, and switching from propane or oil to gas can qualify you for PECO's $400 heating-conversion rebate. The catch is that gas mains don't reach every road in the outer ring, so the first step is confirming service is available at your address.
Yes. Phoenixville sits in PECO's Chester County natural-gas territory. PECO offers $350 for a qualifying ENERGY STAR gas furnace rated 95–96.9% AFUE and $600 for 97%+ AFUE, plus a $400 rebate for converting from oil or propane to gas. You have to be a PECO natural-gas customer, file within 90 days of installation, and the conversion rebate can't be combined with the furnace rebate. New construction isn't eligible.

Phoenixville wears its history on its sleeve. If you own a home in town, that history might matter more than you’d think.
What’s been reborn to become the most talked-about comeback town in the region was once built around iron and steel. The Phoenix Iron Works. The old Foundry. That unforgotten history is one of the reasons why pinning down exactly how much your furnace replacement will cost is about as straightforward as finding parking on a Saturday.
There are three distinct types of homes within Phoenixville: 19th-century rowhomes and twins on Bridge, Gay, and Main; historic Victorians; and a newer layer of mill-conversion lofts and townhomes introduced by the revitalization. Those three homes don’t cost the same to heat, and they don’t cost the same for a contractor to work on.
We’ve been doing this for a while, since 1948, so we know how each detail in your home can impact furnace replacement costs.
Before we dive into the numbers, there’s one important fork in the road. If you currently have a boiler and radiators (not a forced-air system), you’ll need to invest in ductwork before installing a furnace. That’s a bigger job that costs more. If you already have a furnace and ductwork, you’re looking at an equipment swap, keeping your costs in check.

How Much Does Furnace Replacement Cost in Phoenixville, PA?
Here’s the honest equation:
Your price = the equipment tier you choose + what your specific home’s install takes
For most furnaces installed in the Phoenixville area in 2026, most homeowners land between $5,500 and $14,000. Isolating which tier you’re most interested in installing is the fastest way to narrow that price range to something a little more helpful. The foundation of the tiers is this: higher-tier options have more control over heating output than lower-tier options, making them more efficient and your home more comfortable.
| System tier | What it does | Installed price |
|---|---|---|
| Single-speed | Runs full-on or fully off. The most affordable option and a legitimate choice on a tight budget. | $5,500–$7,500 |
| Two-speed | Adds a gentler low setting for steadier temperatures and better efficiency through a long Chester County winter. | $8,000–$12,000 |
| Variable-speed | Modulates to almost any output for the most even comfort, quietest operation, and lowest monthly bills. | $13,000–$14,000 |

While a furnace’s AFUE (Annual Fuel Utilization Efficiency) rating is technically separate from the number of speeds, the two tend to go hand-in-hand. An 80% AFUE furnace represents the least efficient option available, and those marked at 97%+ are among the most efficient. When you’re looking at AFUE ratings, remember that it’s the percentage of fuel that’s converted to usable heat. For example, in an 80% AFUE furnace, 20% of each dollar of fuel is lost entirely through exhaust gas.
Getting the right size (BTUs) for your home matters just as much as, if not more than, efficiency level. An undersized furnace will run itself ragged trying to achieve the temperature set at your thermostat. And an oversized one will short cycle (turn on and off frequently).
The Phoenixville Piece: Where your home puts you
Here’s where the style of your home starts to change your cost. The table below doesn’t represent exact final costs, but can be used for guidance during the planning phase of your furnace replacement.
Now let’s get specific about the scope items that show up in any home. They’re the difference between your final costs staying where they are, or creeping up after an in-home evaluation.
| Your Phoenixville home | Likely install scope | Where you tend to land |
|---|---|---|
| Mill-district loft or newer townhome | Like-for-like swap on sound, modern ductwork. Open floor plans, accessible equipment. | Lower end of your chosen tier |
| Historic-district Victorian | Possible chimney liner or venting work, depending on your water heater. | Middle of your chosen tier |
| Older worker rowhome or twin (Borough Core) | Tight basements, sidewall venting, common oil or propane conversions, and often a chimney liner for your water heater. | Upper end of your chosen tier |
The scope items in the right two columns (venting, liners, conversions) are what move your final number within a tier. See the sections below for what each involves.
What Actually Moves Your Phoenixville Number
A few cost factors are true of any furnace job: the condition of your ductwork (do yours need to be resealed?), your home’s heating capacity needs (finding the right level of BTUs), and the quality of your installer (a low-ball quote is a red flag).
When higher efficiency means more than just a new furnace
On an older Phoenixville Borough home, upgrading to a higher efficiency sometimes sets off a domino effect of related work. Upgrading from a furnace rated lower than 90% AFUE to one rated 90% or higher is a valuable investment that’ll reduce your monthly bills now and in the future. However, it also changes the system’s venting requirements. Specifically, it’ll require a new PVC exhaust through a sidewall rather than up the old masonry chimney.
In a newer home, this may not change the picture much. For many older homes in Phoenixville, it involves something you may not even be thinking about right now: your water heater.
Your chimney vents exhaust gas from both your water heater and your sub-90% AFUE furnace. When you step up to a higher efficiency furnace, its exhaust will run through a PVC pipe and out of a sidewall instead of through the vertical chimney. Your chimney will then only facilitate venting your water heater’s exhaust going forward, often making it oversized for your now-stranded water heater. It may not seem vital, but without proper chimney lining, your water heater will no longer vent properly.
Taking care of your chimney liner may not be a huge expense, but it’s also not talked about enough and is well worth knowing about as early as possible.
Converting off oil or propane
Have you thought about how your fuel can work for you lately?
A lot of Chester County homes rely on propane or oil. A furnace replacement is the natural moment to switch to natural gas, if it’s available to your home. There’s some labor overlap, and converting can unlock PECO’s rebates. Our oil vs. natural gas breakdown covers the trade-offs.
What a Real Phoenixville Quote Can Look Like
Here are two examples that can help make that original equation concrete. (Totals are illustrative, and actual prices are set by an in-home assessment.)
Your price = the equipment tier you choose + what your specific home’s install takes
- A mill-district condo, like-for-like gas swap. The ductwork is already in good condition, the existing furnace is accessible, and is being replaced with the same fuel type. This is a clean scenario: the equipment tier you choose impacts price, and not much else does. Expect to land near the lower-to-middle of your chosen tier.
- A 1920s twin off Bridge Street, converting from oil. Here, the scope starts to stack up. Starting with the furnace itself, plus a new gas line, possible oil-tank removal, a new PVC vent, and a chimney liner for the stranded water heater. The same tier of equipment as the condo might have a meaningfully higher total.
The same furnace, with two very different numbers. That’s the Phoenixville story, in just one comparison.
Furnace, Heat Pump, or Dual-Fuel?
If your air conditioner is also running closer to the end of its life, it’s worth looking at your whole home comfort system. A heat pump offers both cooling and efficient electric heating. Pairing one with a furnace (also called a dual-fuel system) is one of the strongest strategies to maximize comfort while minimizing monthly costs. And replacing both your AC and furnace at the same time typically saves $2,000 to $3,000 versus doing them separately.
How to Save on Your Phoenixville Furnace
- Claim PECO rebates. A qualifying 95-96.9% AFUE furnace earns a $350 rebate, and a 97%+ AFUE furnace earns $600 through the PECO Home Rebates Program. The program can also lower conversion costs, with a $400 rebate when you switch from oil or propane to natural gas.
- Bundle the furnace and AC in the same job. If your cooling is also approaching 10-12 years old, combining the two installations usually saves $2,000 to $3,000.
- Plan for spring or fall. Replacing a furnace that’s failed in February leaves little time to compare options or catch off-season pricing. You may find meaningful savings by taking a proactive approach.
- Use financing to put a higher-efficiency system within your budget, rather than settling for a lower tier.
