An Amana 2-stage furnace typically costs $4,000-$8,500 installed, with a common midrange total near $6,000. The Amana 2-stage furnace price depends mainly on heating capacity, 80% versus 96% AFUE efficiency, venting changes, local labor, and whether the job is a replacement or a new installation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed furnace replacement | $4,000 | $6,000 | $8,500 | Typical equipment and standard installation |
| Furnace equipment only | $1,800 | $2,700 | $4,000 | Model, capacity, and distributor affect price |
| Installation labor | $900 | $1,500 | $2,600 | More for venting or duct modifications |
| Installed cost per home square foot | $2.00 | $3.50 | $5.50 | Rough comparison, not a sizing method |
What a typical Amana 2-stage furnace installation costs
For a straightforward replacement in an existing home, a standard-efficiency Amana two-stage gas furnace often totals $4,000-$6,500 installed. A high-efficiency 96% AFUE model commonly lands around $5,000-$8,500 when venting, condensate drainage, and other required work are included. Equipment-only pricing is often $1,800-$4,000 before installation, sales tax, or accessories.
A practical budget for a standard replacement is about $5,000-$7,000. That estimate assumes a properly sized furnace, usable ductwork and gas connections, ordinary access, and no major code upgrades. Prices vary by model and local contractor; square footage alone does not determine furnace size.
Assumptions: Existing gas furnace location, standard replacement, typical U.S. labor market, no major duct repairs.
How equipment, venting, and labor shape the quote
Contractors may quote equipment, installation, and required job work together or as separate lines. Comparing the included scope matters: one bid may include a thermostat and haul-away, while another charges extra for both.
| Quote component | Low | Average | High | What changes the charge |
|---|---|---|---|---|
| Amana furnace | $1,800 | $2,700 | $4,000 | Efficiency, capacity, model, and supplier |
| Labor | $900 | $1,500 | $2,600 | Removal, access, and installation complexity |
| Venting and drain materials | $150 | $500 | $1,200 | Often higher for high-efficiency PVC venting |
| Permit and inspection | $50 | $200 | $500 | Local requirements and permit fees |
| Haul-away and disposal | $75 | $150 | $300 | Old equipment handling and site access |
Labor commonly accounts for roughly $900-$2,600 of the installed quote. A rough labor calculation is ; for example, 8-14 hours at $100-$185 per hour produces $800-$2,590 before any separate trip or disposal charges.
How AFUE, BTU capacity, and venting change the price
An 80% AFUE furnace sends more exhaust through a conventional metal flue, while a 96% AFUE unit extracts more heat and typically needs PVC intake and exhaust pipes plus a condensate drain. Switching from an older 80% system to a high-efficiency model can add about $500-$1,800 for equipment and installation changes, depending on the existing setup.
Capacity also affects price. Residential models around 40,000-60,000 BTU are generally less costly than units around 80,000-100,000 BTU, but a larger furnace is not automatically better. A heat-loss calculation should determine the required output; oversizing can cause short cycling and uneven comfort.
Efficiency upgrades cost more upfront when venting or drainage must be added. A new PVC route through a finished area, difficult chimney connection, or extensive gas-line work can push the quote above a like-for-like replacement.
What three Amana replacement quotes might include
These examples show how scope changes the price, not fixed national rates. Each assumes replacement of an existing gas furnace in an occupied home.
- Basic 80% AFUE replacement: A 60,000-BTU unit, 8-10 labor hours, standard flue connection, and old-furnace removal might total $4,300-$5,800. The implied installed rate is about $2.50-$3.40 per square foot for a 1,700-square-foot home.
- 96% AFUE replacement: A 70,000-BTU unit, 10-13 labor hours, PVC venting, condensate drain, and permit might total $5,500-$7,500. Vent routing and drainage account for much of the difference.
- Complex high-efficiency changeout: An 80,000-BTU unit, 14-18 labor hours, new vent route, drain pump, and limited duct adjustments might total $7,200-$9,500. Tight access or code corrections can add cost.
Why furnace labor rates differ across U.S. regions
Installed quotes in high-cost coastal metros and dense cities can run about 10%-25% above national midrange estimates, while some rural markets may be 5%-15% lower. The gap reflects local wages, permit fees, travel time, contractor availability, and distributor pricing; it does not mean every city follows the same pattern.
Compare local bids on identical model numbers and included work. Ask for the furnace’s AFUE rating and BTU input, plus separate prices for labor, venting, disposal, permit, and any duct changes. A low equipment price can still lead to a higher total if the installation scope is incomplete.
Which extras can raise a two-stage furnace replacement bill
Common add-ons include a compatible two-stage thermostat at $100-$350 installed, a condensate pump at $150-$400, and duct repairs or modifications at $300-$2,000 or more. A new return-air drop, gas-line upgrade, electrical correction, or chimney liner may be priced separately and can exceed these ranges when access is difficult.
Permit charges are commonly $50-$500, but some areas require additional inspection or code work. Ask whether the quote includes startup testing, airflow setup, old-unit removal, and registration instructions. Manufacturer warranty coverage depends on the model and registration terms; labor coverage may be separate.
How to lower an Amana furnace replacement price
Keeping the project to a like-for-like replacement can avoid unnecessary vent relocation, thermostat upgrades, and duct redesign. If the existing furnace is 80% AFUE and the flue is serviceable, compare the price of another 80% unit with a 96% upgrade rather than assuming the more efficient model will pay back quickly.
Request at least three itemized quotes for the same capacity and efficiency tier. Schedule before peak cold-weather demand when possible, confirm that sizing is based on a load calculation, and ask whether the existing thermostat and venting can safely remain. Avoid cutting costs by skipping permits, safety checks, or required vent work.
When repair may cost less than a full furnace replacement
A diagnostic visit commonly costs $75-$200, and many ordinary repairs fall around $150-$800, depending on the failed part and labor. A control-board, inducer, or blower repair can cost more, particularly if parts are difficult to source. Compare the repair estimate with the age and condition of the furnace rather than using age alone as a replacement rule.
If a repair is under about $500 and the furnace has no major safety or heat-exchanger issue, repair may be the lower immediate expense. A repair above $1,000 on an older system deserves comparison with replacement quotes, especially when repeated failures or poor comfort are involved. Get a diagnosis before treating a two-stage furnace as beyond repair.
