Serving West Chester, Exton, Downingtown, Malvern, Phoenixville & Nearby Areas
Three quotes for the same house can differ by four thousand dollars, and the furnace itself is rarely the reason.
Your price is set by the efficiency tier you pick, what the new unit has to vent through, what it burns, and where in the house it lives. Our expert heating installation crew looks at all four in your basement first. Then you get the total number in writing before anyone orders a part.

What a New Furnace Costs in Chester County, Installed
A new furnace in Chester County runs $4,000 to $12,000 installed. An 80% efficiency gas furnace sits at the low end and a modulating, variable-speed system at the top. Your price turns on the size of furnace the house calls for, the efficiency tier you pick, and what the venting, fuel line, and ductwork need in order to accept it.
“We recently bought a house in the area and, after moving in, found out our HVAC system needed to be replaced pretty much ASAP. Everyone we encountered from Precision was very informative and empathetic toward our unforeseen situation.”
Three Furnace Tiers, Three Very Different Installation Prices
Furnaces are sold by how much of the fuel they turn into heat. That one number moves the price more than the badge on the front does. Here is what each tier costs installed in a Chester County home.
| System tier | Typical installed price (est.) |
|---|---|
| 80% AFUE single-stage gas furnace | $4,000–$6,000 |
| 95% to 96% AFUE two-stage condensing furnace | $6,500–$9,500 |
| 97%+ modulating, variable-speed furnace | $9,000–$12,000 |
All figures are 2026 estimates. The middle row is where most of this county lands, because a condensing furnace earns its extra cost back over a heating season that runs from October into April.
How a Furnace Quote Gets Built in Your Basement, Not in an Office
A price for a furnace nobody has looked at is a guess with a dollar sign on it. So a project manager comes to the house, measures what the home needs rather than reading the sticker on the unit being replaced. We look at the venting, the gas line, the electrical, and the ductwork the new furnace has to join.
That visit costs you nothing and ends with a written flat price covering equipment and labor together. It does not move once you approve it, and nothing gets ordered until you do. Every item that makes up the number is listed, so you can hold our quote beside anyone else’s and compare the same things.
The Six Things That Move a Furnace Price in Chester County
The efficiency tier you choose.
An 80% furnace sends a fifth of the fuel you buy up the flue. A 96% furnace keeps almost all of it, costs more to install, and gives the difference back by cutting down your energy bill every month of a Pennsylvania winter.
What the new furnace has to vent through.
A condensing furnace does not use a chimney. It vents out a sidewall through PVC and produces acidic condensate that needs a drain, sometimes a pump, and sometimes a neutralizer. In an older borough home in Downingtown or Phoenixville, pulling the furnace off the masonry chimney can leave the water heater venting alone into a flue now too large for it, which means lining the chimney as part of the job.
The fuel in the line.
Natural gas across PECO territory is the straightforward case. Propane homes out past the gas main need the right orifices and a gas line sized for the load. Oil systems still heat roughly one Chester County home in eight, and a changeover carries tank removal and new venting with it, which is a different budget from a like-for-like swap.
Where the furnace sits.
A basement is the easy install, and the price reflects it. An attic or a crawl space adds hours of labor and a longer condensate run to the identical furnace, and a finished attic in a borough twin can add more than the efficiency upgrade does.
The ductwork it connects to.
A 2005 build in Exton or Chester Springs usually hands the new furnace a duct system it can work with. A house that has been added onto twice since 1930 often needs a new return drop and fresh sheet metal before a variable-speed blower can do what it was bought to do.
The heat output your house needs.
Furnaces are sized in BTUs, and the old unit is a poor guide because plenty of them were oversized on the day they went in. An oversized furnace short-cycles, wears itself out, and leaves the rooms furthest from it cold anyway.
How Many BTUs Your House Needs, and What That Costs
| Furnace size | Typical home it heats | Est. installed |
|---|---|---|
| 40,000–60,000 BTU | A borough twin, a row home, or a well-insulated smaller house | $4,000–$8,500 |
| 60,000–80,000 BTU | Most 1,800 to 2,400 square foot homes in the county | $5,000–$9,500 |
| 80,000–100,000 BTU | Larger or older houses, and additions that were never on the original heat plan | $6,000–$11,000 |
| 100,000–120,000 BTU | Big homes, high ceilings, or a house heating a finished third floor | $7,000–$12,000 |
All figures are 2026 estimates. Look at how much those four bands overlap. A bigger furnace adds a few hundred dollars of equipment, while the efficiency tier and the venting work can add several thousand, and it is why a quote cannot be handed out over the phone from a square footage.
What Lands in Your Basement for That Price
- The furnace
- Labor from our own install crew, never a subcontractor
- Removal and haul-away of the old unit before the crew leaves
- New venting and gas connection to code
- Condensate drain and pump where a high-efficiency unit needs one
- New return drop and sheet metal where the ductwork calls for it
- Thermostat setup and a walk-through
- Commissioning and airflow testing
- Warranty registration
- Cleanup
When a quote comes in noticeably cheaper, the gap is almost always in that list rather than in the equipment, so ask the other company which of those lines their number includes. We do not pull or file permits. Arranging that is the homeowner’s responsibility, and we will tell you which one your township wants.
Putting $2,000 Into a Sixteen-Year-Old Furnace, and What That Math Looks Like
Most furnace faults are worth fixing and cost a few hundred dollars. The question only gets hard when a big number lands on an old cabinet. A $2,000 repair on a sixteen-year-old furnace is a quarter of a new system spent on a machine with a few winters left, and the next failure is already closer than the last one was.
| Factor | Repair usually costs less | Replacement worth pricing |
|---|---|---|
| Age | Under about 12 years | 15 years and up |
| Repair cost | A few hundred dollars | Several thousand, or a heat exchanger |
| Failure history | First fault this season | Third call in two winters |
| Parts | Current and on the shelf | Discontinued or slow to source |
| Fuel bills | Steady against last winter | Climbing while the house has not changed |
You get both numbers side by side, because that comparison belongs to you rather than to us. When the repair is the better spend, our technicians find the fault and fix it instead.
Turning a Furnace Bill Into a Monthly Payment
A furnace is the kind of purchase most households have not budgeted for, and it tends to announce itself on a cold night rather than at a convenient moment. Wells Fargo financing covers the job at 0% for 12 or 18 months for qualified buyers. It is subject to approval, with longer terms available when spreading it further makes it more convenient to pay.
