What does furnace replacement cost in Des Moines?
Realistic budgeting ranges for a new furnace in Des Moines, IA — how AFUE efficiency, size, and venting change the price, and what an honest quote should include. These are ranges, not quotes.
Budget ranges
How much is a new furnace in Des Moines, IA?
A furnace replacement in Des Moines typically falls between $3,500 and $12,000. The biggest lever is the AFUE efficiency tier, but the size your home needs and whether a high-efficiency unit requires new PVC venting and a condensate drain also move the price. Treat these as budgeting brackets and get an on-site quote for a real number.
| Efficiency tier | What it is | Typical range |
|---|---|---|
| 80% AFUE, single-stage | Standard-efficiency gas furnace | $3,500 – $7,000 |
| 90–96% AFUE, two-stage | High-efficiency, condensing furnace | $4,500 – $9,500 |
| 97%+ AFUE, modulating | Premium variable-speed, max efficiency | $6,000 – $12,000 |
Ranges are non-binding estimates for planning only and still need local verification — your quote may land outside them. Weighing a heat pump instead? Compare furnace vs. heat pump.
What moves the price
AFUE efficiency tier
AFUE is the share of fuel turned into heat. Moving from an 80% to a 96% furnace cuts winter gas waste but raises the equipment price.
Size (BTU) & staging
The right heat output comes from a load calculation. Single-stage, two-stage, and modulating burners each change comfort and cost.
Venting & condensate
A condensing (90%+) furnace needs PVC venting and a condensate drain. Converting from an older metal-vented unit adds materials and labor.
Gas line & electrical
Gas supply sizing, a new shutoff, or wiring for a variable-speed blower can add to the install depending on what your home already has.
Removal, permits & warranty
Hauling away the old furnace, pulling the required permit, and registering the manufacturer warranty are part of an honest, all-in price.
Iowa local truth
“A bigger furnace will heat my house better.” In an Iowa winter, an oversized furnace actually heats worse — it blasts on, overshoots, and shuts off in short cycles that leave cold spots, wear out the ignition and blower faster, and waste gas. A right-sized furnace runs longer, gentler cycles and keeps the whole home even.

Common questions
How much does a new furnace cost in Des Moines?
Most furnace replacements fall in a broad range of roughly $3,500 to $12,000 depending on the AFUE efficiency tier, the size your home needs, and whether the install requires new venting, gas, or electrical work. These are placeholder budgeting ranges — an accurate number requires an on-site assessment.
Is a 96% AFUE furnace worth it in Iowa?
It often makes sense here because IA winters are long, so a furnace runs for months and the fuel savings have time to add up. Whether the higher efficiency pays back depends on your gas rate and how the home is used — a professional can model it for your situation.
What is AFUE?
AFUE (Annual Fuel Utilization Efficiency) is the percentage of fuel a furnace converts into usable heat over a season. An 80% furnace wastes about 20 cents of every fuel dollar up the flue; a 96% furnace wastes far less.
Can I finance a furnace replacement?
Yes. All Seasons HVAC offers financing through Optimus so you can budget a new furnace as a monthly payment instead of paying everything up front.
