A Granby Conforto furnace typically costs about $4,500-$9,500 installed in the United States, with a national planning average near $6,800 for a straightforward oil-furnace replacement. The final price depends on capacity, burner and venting work, removal needs, local labor rates, and whether the existing oil tank and chimney can remain in service.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace equipment | $2,500 | $3,800 | $5,500 | Unit and standard burner configuration |
| Installed replacement | $4,500 | $6,800 | $9,500 | Typical changeout with usable existing connections |
| New venting or chimney work | $400 | $1,200 | $3,000 | Depends on liner, vent route, and code needs |
| Removal and disposal | $200 | $450 | $900 | Higher for difficult access or extra equipment |
Granby Conforto furnace prices for a standard replacement
For a typical U.S. home replacing an existing oil furnace, a Granby Conforto installation often lands between $4,500 and $9,500. A practical budget figure is around $6,800, assuming an appropriately sized furnace, standard burner setup, accessible basement or utility room, and no major chimney, duct, or oil-tank repairs. Rural delivery charges and higher-cost Northeast labor markets can push a comparable job above that range.
Equipment-only pricing commonly runs about $2,500-$5,500, depending on model, capacity, burner configuration, and supplier availability. Installation labor, startup, and basic connections add roughly $1,500-$3,000. A high-efficiency configuration, complicated venting, or substantial site work can raise the total beyond $10,000. Assumptions: U.S. pricing, standard materials, ordinary access, and replacement of a functioning oil-heating system.
Use $4,500-$9,500 as a starting installed range, not a guaranteed contractor quote. Compare estimates only after confirming the exact model, included controls, venting scope, disposal, and startup services.
What the oil furnace quote includes from burner to labor
A quote may list the furnace separately from the burner, controls, installation work, and venting. Some packages include a burner and standard setup; others show them as separate line items. Ask whether the price covers reconnecting the existing oil line, wiring the thermostat, adapting the supply and return ducts, testing combustion, and explaining basic operation.
| Quote component | Typical range | Unit or basis | What changes the charge |
|---|---|---|---|
| Conforto furnace and burner package | $2,500-$5,500 | Per system | Capacity, model, supplier, included burner |
| Installation labor | $1,200-$2,800 | Per replacement | Access, duct changes, crew hours |
| Venting and chimney connection | $250-$1,800 | Per system | Existing liner and vent route |
| Controls, fittings, and small materials | $150-$650 | Per system | Thermostat, wiring, oil-line fittings |
| Removal and disposal | $200-$900 | Per old unit | Weight, stairs, local disposal fees |
Contractor labor commonly works out to roughly $75-$150 per hour per technician, but many firms quote a flat installation price instead. A basic changeout may require 8-14 labor hours; that total can represent a two-person crew working part of a day rather than one technician’s full-day schedule. Ask for an itemized quote that distinguishes included work from allowances and optional upgrades.
How BTU capacity, AFUE rating, and chimney condition change price
Capacity is a major equipment and sizing consideration. Residential oil furnaces commonly fall around 70,000-140,000 BTU per hour, but the correct size depends on heat-loss calculations, insulation, window area, and climate—not simply floor area. Moving from a roughly 80,000-BTU unit to a 120,000-BTU unit can add about $300-$900 to equipment pricing, depending on model availability and configuration. Oversizing can increase cycling and reduce comfort, so a larger unit is not automatically a better value.
Efficiency ratings and burner options also affect the initial quote. A higher-efficiency model or upgraded burner package may add roughly $400-$1,500 compared with a basic configuration, while actual fuel savings depend on the old system’s condition, local heating-oil price, and household use. Ask the installer to identify the model’s published efficiency and explain the expected operating difference rather than relying on a general savings promise.
Chimney condition can produce a larger surprise. A usable lined chimney may need only a basic connection, while a damaged or unsuitable flue could require a liner or a different venting arrangement costing $600-$2,500 or more. Confirm both the furnace capacity calculation and chimney inspection findings before approving the equipment order.
How long does a Conforto furnace installation take?
A straightforward replacement usually takes one workday, often about 6-10 hours on site for a two-person crew. The job can stretch to 1-2 days if installers must modify ducts, replace an oil-line section, install a chimney liner, correct wiring, or work around tight stairs and limited clearance. A new installation in a home without existing oil-furnace connections takes longer and requires additional planning.
Labor pricing varies by market and scope. A basic changeout may include roughly $1,200-$2,800 in labor, while custom venting, duct alterations, or a multi-stage commissioning process can add $500-$2,000. Scheduling can also affect the quote: emergency winter replacement may carry a $200-$800 rush charge when a contractor has to rearrange work or dispatch after hours.
Before scheduling, ask how long heat will be unavailable, whether temporary heat is included, and whether the installer will complete startup and combustion testing on the same visit. One-day installation is a reasonable expectation for a simple replacement, but the quote should account for actual site conditions.
Removal, oil-line work, and venting add-ons to budget for
Existing connections can keep the project near the lower end of the price range, but worn or noncompliant parts may need replacement. Removing and disposing of an old furnace often costs $200-$900. A section of oil line, filter, or shutoff replacement may add $150-$700, while a new thermostat or control wiring may add $100-$500. Prices depend on access, material requirements, and local labor minimums.
Venting and chimney repairs are among the most variable extras. A basic flue connector can cost a few hundred dollars, while a stainless-steel liner or more extensive venting work may total $600-$2,500. If the existing oil tank is leaking, undersized, or no longer acceptable under local rules, tank work is separate and can add approximately $1,000-$4,000 or more depending on tank type, location, and removal requirements.
Some contractors charge a diagnostic or site-visit fee of about $75-$250, which may be credited toward the installation. Ask whether permits, inspection fees, delivery, and disposal are included. Request a written list of exclusions so that a low base quote does not conceal predictable add-on charges.
How Conforto compares with a standard gas furnace or boiler
A Granby Conforto is an oil-fired furnace, so it is not a direct equipment swap for a gas furnace or hydronic boiler. Replacing an existing oil furnace with another oil unit usually avoids the major conversion costs and often produces the lowest project total. A comparable gas-furnace replacement commonly costs about $4,000-$8,500 installed where gas service and compatible venting already exist; adding a gas line or changing venting can raise that amount.
Converting from oil to gas is a larger scope. Depending on utility access, piping, venting, and equipment, a conversion can run roughly $7,000-$15,000 or more. Replacing an oil furnace with an oil boiler is also not a like-for-like installation: boiler, piping, radiators, and controls can put a project around $7,000-$14,000 when substantial system work is needed.
Operating-cost comparisons require local fuel prices and system efficiency. A lower installation quote may not mean lower five-year spending if fuel use, maintenance, or needed upgrades differ. Compare total installed scope and expected fuel costs, not just the furnace sticker price.
Why Northeast and rural installation quotes differ
Oil-heating equipment is more common in the Northeast, where contractors and suppliers may have greater familiarity with Conforto systems. Even within that region, dense urban areas can have higher labor and permit charges than smaller towns. A similar replacement may be about 10%-20% above a national planning estimate in a high-cost metro area; rural jobs can run 5%-15% higher when travel, delivery, or limited contractor availability adds expense.
In parts of the Midwest or South where oil furnaces are less common, the equipment may require special ordering or freight. That can add approximately $150-$600, and limited local service experience may affect scheduling. These regional differences are not fixed premiums: a straightforward job with local stock can still beat a complicated project in a traditionally oil-heated area.
Local permit, inspection, and disposal requirements also affect totals. Depending on jurisdiction, permit and inspection charges may range from about $50-$400, while some local rules require chimney, fuel-line, or tank work before approval. Ask contractors to identify freight, travel, permit, and disposal costs separately when comparing regional quotes.
Which choices can lower a Granby replacement bill?
Keeping the project to a true replacement can control costs. If the existing chimney, oil tank, ducts, electrical connections, and thermostat pass inspection, retaining them may avoid hundreds or thousands of dollars in extra work. That does not mean retaining unsafe or damaged components; it means asking for the inspection result and repair reason before approving replacements.
Get at least three written quotes for the same capacity range and model configuration. Compare the included burner, controls, venting, startup, disposal, warranty, and permit handling. A quote $800 lower may exclude a chimney liner or old-unit removal, so the bottom-line number alone is not a reliable comparison. Scheduling outside a peak cold-weather emergency can also reduce rush fees and improve contractor availability.
Choose equipment based on a documented heat-loss estimate rather than upsizing without evidence. Avoid paying for controls or accessories that do not match the home’s system, and ask whether a repair is viable if the existing furnace has a limited, identifiable fault. The most dependable savings come from controlling scope and comparing complete quotes, not skipping safety checks or required venting work.
