A Goodman 80,000 BTU furnace typically costs $3,500-$9,500 installed, with many standard replacements near $5,500-$6,800. The final price depends mainly on AFUE efficiency, venting and ductwork needs, local labor rates, and whether the job is a straightforward furnace swap or a more involved system change.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace equipment | $1,200 | $2,000 | $3,200 | Common 80,000 BTU Goodman models; equipment only |
| Installed 80% AFUE furnace | $3,500 | $5,400 | $7,500 | Basic replacement with standard venting and access |
| Installed 96% AFUE furnace | $4,800 | $6,800 | $9,500 | May require PVC venting, drain work, or electrical changes |
| Labor | $900 | $1,600 | $2,800 | Usually one crew for about 6-10 hours |
| Annual fuel use | $700 | $1,300 | $2,300 | Illustrative gas expense; climate, rates, and use vary |
What an 80,000 BTU Goodman furnace costs installed
For a typical U.S. home replacing an existing gas furnace, a Goodman 80,000 BTU unit costs about $3,500-$7,500 installed at 80% AFUE, or $4,800-$9,500 at 96% AFUE. The middle of the market is roughly $5,400 for a basic-efficiency replacement and $6,800 for a high-efficiency installation.
Equipment-only pricing often falls between $1,200 and $3,200, before installation, shipping, taxes, or contractor markup. Online equipment prices are not equivalent to an installed quote: contractors may include startup, safety checks, warranty registration, removal of the old unit, and responsibility for code-compliant work.
For a like-for-like replacement with normal access, budget about $5,000-$7,000 before unusual duct, vent, or electrical work. The figures assume a standard residential gas furnace, no major asbestos remediation, and average access. Assumptions: standard materials, ordinary replacement scope, and typical U.S. labor rates.
How equipment, labor, and venting appear on a Goodman quote
A useful estimate separates the furnace itself from installation work and optional changes. Costs below are typical ranges, not fixed manufacturer prices; local permit rules and contractor scope can shift the total.
| Quote item | Typical range | Common pricing basis | What it covers |
|---|---|---|---|
| Goodman furnace | $1,200-$3,200 | $1,200-$3,200 per unit | Cabinet, burner, blower, and selected efficiency level |
| Installation labor | $900-$2,800 | $75-$150 per hour | Disconnect, set, connect, test, and commission |
| Venting and condensate | $150-$1,200 | $5-$20 per linear ft for basic pipe work | Flue adjustments, PVC venting, drain, and fittings |
| Permit and inspection | $50-$400 | $50-$400 per job | Local permit, inspection, or filing fee |
| Removal and disposal | $100-$500 | $100-$500 per old furnace | Disconnecting, hauling, and disposal |
| Accessories or controls | $100-$900 | $100-$900 per system | Thermostat, filter cabinet, or safety updates |
Labor often includes more than lifting out the old furnace. The installer checks gas connections, electrical wiring, airflow, temperature rise, combustion, and condensate drainage where applicable. Some quotes bundle these items into one installation fee, so line-item differences do not always mean one contractor is charging more for the same work.
Ask whether the quote includes permit, disposal, vent materials, startup testing, and tax. A low equipment price can still lead to a higher installed total if required accessories or code corrections are listed as extras.
Why 80% versus 96% AFUE changes the installed price
AFUE measures how much of the furnace’s fuel becomes usable heat over a heating season. An 80% AFUE model is generally less expensive to install when an existing metal flue is suitable. A 96% AFUE model captures more heat but produces condensate and usually needs plastic vent pipes routed outdoors.
The efficiency choice can add roughly $1,000-$2,500 to the installation when venting, drainage, or electrical work changes. A 96% model may cost less to operate in a cold climate with high gas use, but the savings depend on local gas and electricity prices, thermostat settings, and the old furnace’s condition.
Capacity also needs verification. An 80,000 BTU input rating is not the same as 80,000 BTU of delivered heat; at 80% AFUE, nominal output is about 64,000 BTU, while a 96% unit produces about 76,800 BTU. A load calculation, rather than the old furnace label alone, helps determine whether 80,000 BTU is appropriate.
Do not pay for higher efficiency or capacity without checking the home’s heating load and venting plan. Oversizing can cause short cycling and uneven comfort, while undersizing can leave a home struggling during cold weather. Assumptions: AFUE output estimates use rated input multiplied by seasonal efficiency; actual operation varies.
How Midwest, Northeast, and Sun Belt quotes differ
Installed prices commonly vary by 10%-25% between markets because of labor costs, contractor availability, permit requirements, and the complexity of local housing stock. A simple replacement in a lower-cost Midwest or Southern market may land near $3,500-$6,500; comparable work in a high-cost Northeast or West Coast metro can reach $5,000-$9,500.
Older homes can carry extra charges for tight basements, masonry chimney liners, obsolete wiring, or difficult equipment access. In some areas, a high-efficiency furnace also requires a longer PVC vent route or a condensate pump because there is no nearby drain. Those site-specific expenses can matter more than the regional average.
Extreme winter demand can narrow appointment availability and encourage emergency pricing. A planned replacement during mild weather may avoid rush fees, although seasonal promotions and contractor schedules vary by city. Rural buyers may also see travel or delivery charges if the installer serves a wide service area.
Compare local quotes with the same furnace efficiency, permit scope, vent route, and warranty terms. A regional price difference is meaningful only after confirming that each estimate covers the same work.
How long Goodman furnace installation takes and what labor covers
A direct swap usually takes a two-person crew about 6-10 hours, with labor charges commonly totaling $900-$2,000. A more complicated high-efficiency conversion may take 8-14 hours and cost $1,500-$2,800 in labor, especially if the installer must route new vents, add a condensate drain, or correct gas and electrical connections.
Installation commonly includes shutting down utilities, removing the old unit, setting and leveling the new furnace, reconnecting ducts and fuel, and testing operation. The crew should confirm airflow, temperature rise, safety controls, and combustion settings. Work that requires a new flue liner or substantial duct modification may extend the job beyond one day.
Scheduling a replacement before the old furnace fails can help avoid emergency service charges, which may add $150-$500 or more for after-hours dispatch and urgent work. That fee is separate from the installation price, and not every contractor uses the same callout structure.
Labor estimates are easiest to compare when the quote states crew size, estimated hours, and included testing. A low labor line may exclude work that appears later as separate vent, drain, or electrical charges.
Three Goodman 80,000 BTU installation quotes compared
These examples show how scope changes the total for the same nominal furnace capacity. Prices represent plausible installed estimates rather than guaranteed local offers; equipment model, tax, permit rules, and contractor warranty can change the final bill.
| Scenario | Equipment and scope | Labor and materials | Estimated total |
|---|---|---|---|
| Basic replacement | 80% AFUE; reuse suitable flue and thermostat | 7 hours; $1,400 labor, $600 removal and permit | $4,300-$5,900 |
| High-efficiency conversion | 96% AFUE; new PVC venting and condensate drain | 10 hours; $2,000 labor, $700 vent and drain work | $5,800-$8,200 |
| Restricted-access upgrade | 96% AFUE; difficult basement access, filter cabinet, wiring correction | 12 hours; $2,400 labor, $1,000 added work | $7,500-$9,500 |
In the basic example, a $1,500-$2,500 furnace, labor, and modest permit and disposal charges make up most of the quote. The conversion costs more because the installer adds vent piping and drainage. The restricted-access project adds labor and accessories, not simply a more expensive furnace.
Use the scope details—not just the total—to judge whether two quotes are comparable. Confirm the exact model number, AFUE, included thermostat, haul-away, permit, and warranty before comparing the final amounts.
Which add-ons can push an 80,000 BTU furnace quote higher
Common extras include a new filter cabinet at $150-$500, a basic programmable thermostat at $100-$350 installed, and a condensate pump at $150-$400 when gravity drainage is unavailable. A new return-air drop or duct transition can add $300-$1,200, while substantial duct repairs can exceed that range.
Gas piping changes may cost $200-$1,000, depending on length and access. Electrical corrections can add $150-$600. If a high-efficiency unit vents through a chimney that also serves other equipment, a liner or separate vent plan may be needed; that work can add several hundred dollars or more depending on the building.
Old furnace removal and disposal often costs $100-$500 when not bundled. Asbestos insulation, inaccessible crawlspaces, water damage, or a chimney needing repair can require specialist work and a separate estimate. These are not standard furnace installation items, so the contractor should identify them before work starts whenever possible.
Separate required code or safety corrections from optional comfort upgrades. A replacement filter cabinet or thermostat may be useful, but it should not be confused with work necessary to install and operate the furnace safely.
How to lower the Goodman furnace price without cutting safety
Request at least three written estimates and give each contractor the same scope: 80,000 BTU capacity under consideration, preferred AFUE, removal requirements, thermostat needs, and any known vent or duct constraints. Ask each bidder to perform or explain the sizing check. This reduces the chance of comparing a basic swap against a quote that includes significant upgrades.
Choose efficiency based on expected use and local utility costs rather than assuming the highest AFUE is automatically the best value. If the existing flue is serviceable and an 80% model is permitted locally, avoiding new PVC venting may save $500-$1,500 or more. Conversely, replacing an old chimney-dependent system with 96% efficiency can be practical when the home’s fuel use is high and the vent route is straightforward.
Prepare the work area by clearing a path to the furnace and removing stored items near the equipment. Confirm in advance whether haul-away, permit, and thermostat are included. Schedule before a breakdown if possible, and avoid paying for unnecessary duct replacement when a qualified inspection finds the existing ducts serviceable.
Keep safety checks, permits, and commissioning in the scope while trimming optional upgrades. A bargain quote that omits testing, code-required venting, or required permits can create costly corrections and safety risks later.
