Oil Furnace Cost: 2026 Installed Price Calculator
Mike Martin, MA CSL, is the founder and construction cost editor of RemodelingExpense. His residential construction experience informs the site’s cost research, calculators, and homeowner project guidance.
Oil furnace cost ranges from $6,500 – $15,000 per system installed, with most replacement projects costing less when the existing oil tank, oil line, chimney, ductwork, and thermostat setup can be reused.
Use this calculator for oil-fired forced air furnace replacement where heated air is distributed through existing or planned ductwork.

Use your estimate as a starting point, then compare real prices from local contractors.
| Cost item | Low estimate | High estimate |
|---|---|---|
| Equipment and materials | $3,250 | $10,500 |
| Labor | $3,250 | $4,500 |
| Estimated oil furnace cost | $6,500 | $15,000 |
| Installed cost per system | $6,500 | $15,000 |
Why your price may change
- Local labor rates vary.
- Material quality affects the price.
- Old material removal, repairs, permits, or code updates can add cost.
- Hard-to-reach areas, complex layouts, rush jobs, or premium contractors may cost more.
Estimate includes local labor adjustments and may differ slightly from rounded national cost examples.
Oil Furnace Cost vs Value
Oil Furnace may recover about 20%–40% of its cost.
Bottom line: Oil furnace cost depends on furnace size, AFUE rating, burner type, oil tank condition, oil line condition, chimney or flue requirements, duct airflow, thermostat controls, permits, removal, access, and local labor rates.
Worth it: Homeowners replacing an existing oil-fired ducted furnace where oil service, venting, and ductwork are already in place.
Skip it: Choose forced air furnaces for broader fuel-type pricing, forced air gas furnaces for gas or propane heating, forced air electric furnaces for electric resistance heat, or heat pump systems for heating and cooling.
ROI ranges are planning estimates and should not be treated as an appraisal. This is only an estimate. Real resale value depends on your home, neighborhood, market, project quality, and buyer demand.
Contractor Reality Check
An oil furnace quote should not stop at the furnace box. Oil tank condition, oil line condition, burner setup, chimney draft, flue pipe, duct airflow, removal, and permit requirements can change the final price quickly.
My rule of thumb: ask whether the quote includes the furnace, burner, oil line connection, flue pipe, chimney inspection, thermostat, filter cabinet, permit, old unit removal, startup, and duct airflow checks.
What to Confirm Before You Sign
- Furnace size: confirm the BTU input and output and whether the contractor checked the home heating load.
- AFUE rating: ask what efficiency rating is included and whether a higher tier changes the cost.
- Burner type: confirm whether the burner is included, reused, replaced, or adjusted during startup.
- Oil tank condition: ask whether the tank, filter, shutoff, and oil line are in usable condition.
- Chimney or flue: confirm draft, flue pipe condition, chimney liner needs, and venting requirements.
- Duct airflow: ask whether returns, supply ducts, static pressure, and filter cabinet sizing were checked.
- Buffer: budget 10% to 20% for oil line work, flue repairs, chimney updates, duct repairs, permits, removal, or access issues.
Surprise Costs That Move the Price
| Item | Why It Adds Cost | Typical Add |
|---|---|---|
| Oil line or filter work | Older oil lines, filters, shutoffs, or fittings may need replacement before startup. | $300 – $2,000+ |
| Chimney or flue updates | Draft issues, damaged flue pipe, or chimney liner work can add cost. | $500 – $4,500+ |
| Oil tank issues | A leaking, aging, or non-compliant oil tank can turn a furnace replacement into a larger project. | $1,500 – $6,000+ |
| Duct airflow corrections | Leaky ducts, undersized returns, or high static pressure can limit furnace performance. | $500 – $5,000+ |
| Old furnace removal | Oil furnaces can be heavy, messy, and harder to remove from basements or tight utility rooms. | $400 – $2,000+ |
Oil Furnace Cost by Type
| Oil Furnace Type | Typical Cost | Best For |
|---|---|---|
| Standard oil furnace | $6,500 – $11,000 per system | Basic replacement where the oil tank, oil line, chimney, and ductwork are usable. |
| Higher efficiency oil furnace | $8,500 – $16,000+ | Homes staying with oil heat that want better fuel efficiency and updated equipment. |
| Oil furnace with chimney work | $7,500 – $18,000+ | Homes that need flue pipe, draft, chimney liner, or venting corrections. |
| Oil furnace with tank or line work | $8,000 – $20,000+ | Older oil systems with aging tanks, oil lines, filters, or shutoffs. |
| Oil furnace replacement package | $6,500 – $15,000+ | Furnace, burner setup, standard connections, removal, startup, permit, and basic accessories. |
Is an Oil Furnace Worth It?
An oil furnace is worth it when you already have oil service, an existing oil tank, compatible venting, and ductwork in place. It is usually less attractive for homes starting from scratch because fuel storage, venting, and maintenance requirements can add cost.
Choose forced air furnaces for broader fuel-type pricing, forced air gas furnaces for gas or propane heating, forced air electric furnaces for electric resistance heat, or heat pump systems for heating and cooling.
