A new heating furnace typically costs $3,500-$7,500 installed, with an average near $5,500 for a standard gas furnace replacement. The final price depends most on furnace type, heating capacity, efficiency rating, installation difficulty, and whether ductwork or venting needs changes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Gas furnace installed | $3,000 | $5,500 | $10,000 | Standard replacement through high-efficiency equipment |
| Electric furnace installed | $2,000 | $4,000 | $6,500 | Often less installation work, but operating costs vary |
| Oil furnace installed | $4,500 | $7,500 | $11,000 | Fuel-system and venting needs affect the quote |
| Gas furnace equipment only | $1,000 | $2,500 | $5,000 | Price varies by capacity and efficiency |
Assumptions: U.S. pricing for a typical single-family home, standard equipment, and accessible replacement location; regional labor and project scope can shift totals.
Installed gas furnace prices by efficiency and size
For a straightforward replacement, a 40,000- to 80,000-BTU gas furnace commonly runs $3,000-$7,500 installed. A 90%-95% AFUE model often costs $3,500-$7,000, while a 96%-98% AFUE furnace with variable-speed features may reach $6,000-$10,000. AFUE measures how much fuel becomes usable heat.
Most standard gas-furnace replacements land around $4,500-$6,500 when existing connections and ducts are usable. Larger homes may need 80,000- to 120,000-BTU equipment, but correct sizing requires a heat-loss calculation rather than a simple square-foot estimate. Oversized equipment can raise the purchase price and cycle inefficiently.
What furnace installation quotes include
A replacement estimate can combine equipment, removal, setup, and small connection changes. The table shows typical line-item ranges for an ordinary gas furnace job; complicated venting or electrical work can add more.
| Quote item | Typical range | Common basis | What changes it |
|---|---|---|---|
| Furnace and controls | $1,500-$4,500 | One unit | BTU capacity, AFUE, blower type |
| Installation labor | $1,000-$2,500 | 6-12 hours | Access, connections, crew size |
| Removal and disposal | $150-$500 | One old unit | Weight, access, local disposal fees |
| Venting, electrical, or gas changes | $200-$1,500 | Per project | Code requirements and existing layout |
| Permit and inspection | $50-$400 | Local permit | City or county rules |
Ask for separate equipment, labor, removal, and modification prices so a low headline quote does not conceal excluded work. A labor estimate can be checked with ; contractor rates commonly work out to about $75-$150 per technician-hour, though quotes may bundle labor into a fixed installation charge.
How BTU capacity and AFUE change the furnace quote
Capacity and efficiency can move the equipment price by thousands of dollars. A basic 60,000-BTU furnace may cost less than a 100,000-BTU model, while a two-stage or variable-speed blower can add roughly $500-$2,000 over a comparable single-stage unit. High-efficiency equipment may also require different venting or condensate drainage.
Replacing like-for-like equipment is usually less expensive than changing fuel type, furnace location, or vent route. A new PVC exhaust run or condensate pump can add $300-$1,200. Duct repairs or resizing can add $500-$3,000 or more, depending on how many runs need work. A contractor should verify duct capacity and perform sizing before specifying a larger furnace.
Why furnace labor and access affect replacement time
A direct replacement often takes one workday, generally 6-10 hours for a two-person crew. A tight basement stairway, attic installation, difficult flue access, or changes to gas and electrical connections can extend the job to 1-2 days and increase labor charges. Emergency or same-day scheduling may add 10%-25% when crews are scarce.
Confirm whether the quoted labor includes startup testing, thermostat setup, and cleanup. A complete installation should include safety checks, airflow verification, and confirmation that the furnace operates correctly. If a quote lists only equipment placement, ask whether commissioning and removal are charged separately.
Regional furnace prices from rural homes to major metros
Local wages, permit fees, climate, and contractor availability affect installed prices. In lower-cost rural markets, a standard replacement may be about 5%-15% below the national range. Major metropolitan areas and high-cost coastal markets can run 10%-25% above it, especially when parking, access, or local code upgrades complicate the work.
Compare quotes from contractors who serve the same ZIP code and specify equivalent equipment. A price difference may reflect labor markets rather than a better furnace. In colder regions, higher-capacity systems are more common, but a proper load calculation still determines whether that capacity is needed.
Extra charges for ductwork, thermostats, and permits
Common add-ons include a programmable thermostat for $100-$500 installed, a new filter cabinet for $150-$600, and duct sealing or minor repairs for $300-$1,500. A return-air modification can cost $500-$2,000. Permit and inspection charges are commonly $50-$400, but some jurisdictions require additional code work when fuel lines or venting are changed.
Get any proposed add-on tied to a specific problem, measurement, or code requirement. Replacing a functioning thermostat or upgrading unaffected duct sections may not be necessary. If a contractor identifies unsafe venting or a gas leak, however, those repairs should be priced and addressed before operation.
Gas, electric, and oil furnace replacement prices compared
Electric furnaces often cost $2,000-$6,500 installed and can suit homes without gas service, though electricity rates may make them more expensive to run. Oil furnace replacements commonly fall between $4,500 and $11,000, with tank, fuel-line, or chimney work potentially adding cost. Gas is frequently the least expensive option to operate where natural gas is available, but local fuel prices determine long-term value.
Compare installation and expected energy use together rather than choosing by equipment price alone. Switching from oil or electric heat to gas can require a new service connection, line, venting, and permits, adding roughly $1,000-$5,000 or more. A heat pump is another alternative, but its installation scope and climate suitability differ from a furnace replacement.
Ways to lower the new furnace price without cutting safety
Keep the existing fuel type, location, and usable venting when the system is safe and code-compliant. Get at least three itemized quotes for the same furnace capacity, AFUE rating, and warranty. Scheduling outside peak winter demand may improve contractor availability, while replacing the furnace before a no-heat emergency avoids rush fees.
Choose efficiency upgrades based on local fuel prices and expected years in the home. A higher-rated furnace costs more upfront and may not repay the premium quickly in a mild climate or short ownership period. Avoid paying for unnecessary duct replacement, oversized capacity, or premium controls; retain required safety repairs and permit work.
