Most homeowners pay $1,200-$5,500 to convert an oil burner to natural gas or propane, with major drivers being burner type, chimney work, and gas line run length. This article outlines typical oil to gas conversion burner cost ranges and the variables that most affect price so buyers can budget and compare quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete burner conversion (typical home) | $1,200 | $2,800 | $5,500 | Assumptions: 1-2 story home, short gas run, standard cast-iron or steel boiler/furnace. |
| Gas line installation (to appliance) | $300 | $900 | $2,000 | Per run; long trenching or meter relocation increases cost. |
| New gas burner unit | $400 | $1,200 | $2,500 | Depends on BTU and brand. |
| Chimney/vent modifications | $150 | $600 | $2,000 | Includes liner, cap, or conversion to direct vent. |
Typical Total Price For Converting An Oil Burner To Gas
Buyers usually see a total project price between $1,200 and $5,500 for converting an oil burner to natural gas or propane.
Typical total assumes replacing the oil burner with a compatible gas burner or installing a new gas-fired burner on the existing boiler/furnace, a 10-25 foot gas line run, no major chimney rebuild, and local labor rates. Low end reflects simple burner swap with a short gas stub; high end includes long gas runs, chimney relining, and permit/inspection fees.
Breaking Down The Quote: Materials, Labor, Equipment, Permits
This table shows the major cost components commonly itemized on conversion quotes.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $400-$2,500 (burner, fittings, valves) | $500-$1,800 ($75-$125 per hour) | $150-$900 (venting, chimney liner, gas regulator) | $50-$400 (local building/inspection fees) | $50-$300 (tank removal, debris) |
Assumptions: 4-16 labor hours, two-person crew for most conversions.
How Gas Line Length And Meter Work Affect Price
Per-foot gas line runs are a primary price driver: expect $8-$25 per linear ft for trenching and piping, versus $4-$9 per ft for interior runs.
If the property requires moving the gas meter or tapping a distant street main, add $800-$4,000 for service upgrade and permits. Interior runs through finished basements are cheaper but may require drywall/trim repair, which adds $200-$1,200.
Burner Size, BTU Rating, And Appliance Compatibility
Higher BTU burners cost more: small residential burners (80k-150k BTU) run $400-$1,000; larger units (150k-350k BTU) run $1,000-$2,500.
Compatibility matters: older boilers may need an adapter or new combustion chamber; when the existing appliance can’t accept a direct gas burner, full appliance replacement can add $2,000-$6,500. Specify BTU requirements when requesting quotes.
Ways To Reduce Oil-to-Gas Conversion Price Without Sacrificing Safety
Choose scope-control tactics: keep the existing combustion appliance if compatible, limit new gas line length, and schedule work off-peak.
- Get three written quotes to compare line-item pricing and labor hours.
- Bundle related work (e.g., gas range or water heater hookups) to reduce mobilization fees.
- Prepare site access and move combustibles to reduce labor time.
- Accept standard materials over premium brands when warranties are comparable.
Regional Price Differences And What To Expect In Your Area
Expect 10%-40% higher labor-driven costs in major metro areas and cold-climate states where demand for heating work is stronger.
Example deltas: Northeast and West Coast +15%-35% vs. Midwest baseline; Rural and some Sunbelt areas -5%-15% on labor but possible higher travel fees. Material costs are more uniform, but permit fees vary widely by municipality.
Common Add-Ons, Removals, And Time Estimates Buyers Should Budget For
Typical additional line items include oil tank removal ($300-$1,200), chimney relining ($400-$2,000), and appliance vent conversion ($150-$900).
| Add-On | Low | Average | High |
|---|---|---|---|
| Oil tank removal (above ground) | $300 | $650 | $1,200 |
| Chimney relining | $400 | $1,000 | $2,000 |
| Direct-vent conversion kit | $150 | $450 | $900 |
Most conversions take 4-16 hours of onsite work spread over one or two days for standard jobs; complex jobs may require several days and multiple inspections.
Sample Real-World Quotes For Typical Home Scenarios
Three realistic quote examples help translate ranges into budgets.
| Scenario | Specs | Labor Hours | Price |
|---|---|---|---|
| Simple swap, short gas run | 100k BTU burner, 10 ft line | 4 | $1,200-$1,600 |
| Standard conversion, moderate run | 150k BTU, 25 ft line, vent kit | 8-10 | $2,500-$3,500 |
| Complex, long run & chimney work | 250k BTU, 60 ft run, relined chimney | 12-20 | $4,200-$6,500 |
Assumptions: mid-range materials, licensed HVAC/plumbing contractors, required permits obtained.
