When homeowners think about replacing their furnace, they often focus on the equipment itself. You’ll see a Goodman 60,000–80,000 BTU furnace listed online for around $2,000–$3,500, depending on the model and efficiency. That seems manageable, right?
But here’s the catch: the installation cost is often just as much—or more—than the furnace itself.
👉 In 2025, installing a new Goodman furnace typically runs anywhere from $3,500 on the low end to $9,000+ on the high end. The price depends on your home’s size, location, ductwork, permits, and whether you add extras like a smart thermostat or indoor air quality upgrades.
I learned this firsthand when I replaced my own system with a Goodman Ultra-Low NOx 80,000 BTU furnace. The unit wasn’t too bad in price, but by the time labor, permits, and a new thermostat were added, the bill was higher than I expected.
This guide breaks down what goes into furnace installation costs in 2025, and how to budget realistically.
⚙️ Equipment Costs: The Furnace Itself
The Goodman 60,000–80,000 BTU range covers most mid-sized homes (1,500–2,500 sq. ft.), depending on climate and insulation.
Price Range
-
60,000 BTU Goodman furnace: $2,000–$3,000
-
80,000 BTU Goodman furnace: $2,200–$3,500
-
Price depends on efficiency (80 AFUE vs. 96 AFUE+) and features (single-stage vs. variable-speed blower).
Ultra-Low NOx Models
-
In states like California and Utah, Ultra-Low NOx compliance is required.
-
These models usually cost $300–$800 more than standard versions.
👉 Tony’s Take:
“My Goodman furnace was about $2,500 before installation. That felt like a deal—until I saw what the rest of the install added up to.”
👷 Labor Costs: Paying the Pros
Even if you buy a furnace online, most homeowners will need a licensed HVAC contractor to install it.
Typical Labor Costs
-
$1,500–$3,000 for a straightforward replacement.
-
Price includes removal of the old furnace, connecting the new one, wiring, gas hookup, and testing.
Why Labor Costs Vary
-
Region: Metro areas (California, New York, Chicago) are more expensive than rural towns.
-
Season: Prices can be higher during peak winter demand.
-
Complexity: If modifications are needed, labor hours increase.
👉 Tony’s Take:
“Labor for my install was $2,000. That covered two techs, a full day of work, and cleanup. Honestly, watching them handle gas lines and electrical connections reminded me why DIY wasn’t an option.”

📏 Home-Specific Factors That Drive Costs
Every home is different. That’s why quotes vary so much, even for the same furnace model.
1. Ductwork Modifications
-
If your ducts are old, leaky, or incompatible, expect an extra $1,000–$2,500.
-
New ducts in a remodel or addition can run $3,000–$10,000+.
-
Proper duct sizing is critical for efficiency and comfort.
2. Gas Line & Venting
-
Upgrading a gas line: $500–$1,000.
-
Switching from standard venting to high-efficiency PVC venting: $800–$1,500.
3. Electrical Work
-
Dedicated circuit or breaker upgrades: $300–$700.
👉 Tony’s Take:
“My house already had compatible ducts and gas lines, so I lucked out. But when I helped a buddy replace his, he spent almost $2,000 extra on duct modifications.”

📜 Permits, Inspections & Code Compliance
You can’t just drop a furnace in and call it a day—local building codes require permits and inspections.
Permit Costs
-
Usually $200–$600, depending on your city or county.
-
Some metro areas may charge more.
Inspections
-
A city inspector ensures your installation meets code for safety and efficiency.
-
Gas lines, venting, and electrical connections must pass inspection.
👉 Tony’s Take:
“I paid about $300 for permits and inspection fees. It was a hassle, but I’d rather have peace of mind knowing everything was done to code.”
