An Infinity 96 gas furnace typically costs $5,000-$9,500 installed, with an average quote near $7,000 for a straightforward replacement. Equipment capacity, venting and ductwork changes, local labor rates, and whether the quote includes a thermostat or haul-away can move the price substantially.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed furnace replacement | $5,000 | $7,000 | $9,500 | Standard access and compatible ductwork |
| Furnace equipment | $2,500 | $3,600 | $5,000 | Price varies by model and capacity |
| Installation labor | $1,500 | $2,400 | $3,800 | Removal and basic connection included |
| High-efficiency venting work | $300 | $700 | $1,500 | More if the route or materials change |
What an installed Infinity 96 furnace usually costs
For a like-for-like replacement, homeowners commonly see total quotes of $5,000-$9,500. A typical middle-range project is about $7,000, including the furnace, installation, ordinary startup checks, and removal of the old unit. A larger or more involved job can exceed that range if it needs duct modifications, new venting, electrical work, or extensive access preparation.
Infinity 96 is a Carrier product family name; available models and specifications can differ. Many units in this category are condensing furnaces with AFUE ratings around 96%, but buyers should confirm the exact model number and efficiency on the written quote. Assumptions: U.S. replacement project, standard-grade installation, existing gas service and ducts in usable condition.
Budget about $5,000-$9,500 installed for a typical replacement, not just the furnace itself.
How equipment, labor, and venting shape the quote
Quotes should separate equipment from installation tasks. The table gives planning ranges for a typical replacement; amounts vary by contractor, region, and exact scope. Permit charges, taxes, and accessories may be itemized separately rather than included in the base price.
| Quote item | Typical range | Pricing basis | What changes the charge |
|---|---|---|---|
| Furnace and controls | $2,500-$5,000 | Per furnace | Model, capacity, included thermostat |
| Removal and installation | $1,500-$3,800 | Per project | Access, piping, electrical connections |
| Venting and condensate parts | $300-$1,500 | Per project | Pipe route, drain location, materials |
| Permit and inspection | $75-$500 | Per permit | Local requirements and jurisdiction |
| Thermostat or control upgrade | $250-$900 | Per control | Compatibility and wiring needed |
Labor is often priced as part of a fixed installation quote, but a rough planning rate is $75-$150 per technician-hour. A two-person crew working 8-12 hours represents $1,200-$3,600 in labor before overhead and other job costs.
Compare the included work line by line, especially venting, disposal, controls, and permits.
Why furnace size and vent routes change the price
Capacity affects the equipment price, but a larger furnace is not automatically the right choice. Common residential sizes span roughly 40,000-120,000 BTU input; the correct size depends on a heat-loss calculation, not simply the old unit’s label or the home’s square footage. A change in capacity can also require adjustments to ducts, gas piping, or electrical connections.
Venting is another meaningful cost driver. A condensing furnace needs suitable intake and exhaust piping and a condensate drain. A short, accessible route may fit within a basic installation, while a run longer than about 20-30 feet, difficult wall penetration, or a drain far from the furnace can add several hundred dollars or more. Quotes should describe the route and materials.
Ask for the proposed BTU capacity and venting scope before comparing totals.
Where a replacement quote can exceed the basic budget
Changing from an older non-condensing furnace can require new PVC vent pipes and a condensate disposal setup. That conversion can add around $500-$1,500, depending on the route and drainage access. A new return-air connection or duct repair may add $300-$1,500; larger duct redesigns can cost more and should be quoted separately.
Old gas shutoff valves, undersized gas lines, unsafe venting, or code deficiencies may also trigger extra work. Ask the contractor to identify required corrections separately from optional upgrades. A permit commonly costs $75-$500, while removal and disposal may be included or itemized at roughly $100-$400.
Written exclusions matter: a low base quote may omit code corrections or duct work.
How Midwest and coastal labor markets compare
Local labor and permitting can shift an otherwise similar installation. For planning, quotes in lower-cost Midwest or smaller-market areas may run about 5%-15% below the national middle, while high-cost coastal metros can be 10%-25% above it. These are broad comparisons, not guaranteed regional prices; local contractor availability and access conditions can outweigh geography.
Cold-weather replacement during peak heating demand may also limit scheduling and raise labor charges, particularly for urgent calls. A planned replacement in a milder season may offer more appointment flexibility, though equipment discounts are not guaranteed. Buyers should compare current local quotes with the same scope rather than applying a regional percentage mechanically.
Use regional percentages only as a rough check against itemized local estimates.
Three realistic Infinity 96 installation quote examples
A simple swap in a moderate-cost market might include a 60,000-BTU furnace, compatible controls, 8 hours of two-person labor, and existing venting that needs only minor adjustment. At $3,300 for equipment, $1,900 for labor, and $450 for parts and permit, the total is about $5,650.
A typical conversion could use an 80,000-BTU unit, new venting, condensate drain work, and 10 hours of crew labor. A sample quote might be $3,800 equipment, $2,500 labor, $850 venting and drain, and $250 permit, totaling $7,400. A complex 100,000-BTU replacement with a longer vent route, duct repair, and difficult access could total $9,000-$11,000.
These examples assume standard residential access; unusual repairs can push totals higher.
Repairing the existing furnace versus replacing it
A diagnostic visit commonly costs $80-$200, with repair totals often around $150-$1,200 depending on the failed part. A control, igniter, or sensor repair may be far less than replacement; a major heat exchanger or control-system failure can make a second opinion worthwhile before committing to a new furnace.
Age, safety, parts availability, and expected future repairs matter alongside the estimate. If the current furnace is relatively new and the repair is limited, repair may be more economical. If it is older, inefficient, or facing multiple costly failures, compare the repair quote with full replacement pricing. Request the diagnosis and repair price in writing before deciding.
Which quote choices can lower the final furnace price
Keep the scope to needed work: avoid replacing usable ducts or adding controls that are not compatible or useful. Ask whether the existing thermostat can operate the quoted model, and have each contractor state the exact furnace model, capacity, venting, permit, disposal, and warranty terms. Three comparable written estimates make omitted work easier to spot.
For a replacement, ask whether minor vent adjustments can use the existing route safely and legally. Do not choose a furnace solely by the lowest capacity or price; improper sizing can affect comfort and operation. Check current manufacturer, utility, and local incentive terms before counting a rebate toward the budget, since eligibility and amounts vary.
The safest savings usually come from comparing identical scopes and avoiding unnecessary add-ons.
