Typical U.S. homeowners pay to replace an oil burner with a natural-gas or propane gas burner; the oil to gas conversion burner cost depends on burner type, fuel line work, venting, and cleanup. This article lists low-average-high price ranges and the main cost drivers so readers can plan a realistic budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete oil-to-gas burner conversion | $1,200 | $3,800 | $8,500 | Depends on venting, labor, and tank removal |
| Gas line run (per linear ft) | $15/ft | $25/ft | $45/ft | Underground or long runs increase cost |
| New gas burner or conversion kit | $300 | $900 | $2,500 | Kit vs. full burner replacement |
| Tank removal (above/belowground) | $400 | $1,200 | $4,000 | Underground tanks much more expensive |

Typical Total Cost To Convert an Oil Burner to Gas
Most full conversions for a 1,200–2,500 sq ft U.S. home range from $1,200-$8,500 total; average projects come in near $3,500-$4,000. Assumptions: single-family home, one heating appliance, standard access, natural gas or propane available within 50 ft.
Per-unit breakdown: burner or conversion kit $300-$2,500; labor and gas line $800-$3,000; venting and controls $200-$1,200; tank removal $400-$4,000.
Line Items in a Typical Conversion Quote: Materials, Labor, Equipment, Permits
| Materials | Labor | Equipment | Permits |
|---|---|---|---|
| $300-$2,000 (burner, controls, piping) | $600-$2,500 (plumber/HVAC hours) | $100-$1,000 (tools, temporary heaters) | $50-$600 (local permits, inspections) |
Labor is often the largest single line item because of gas-line installation and safety testing.
How Run Length, BTU Rating, and Venting Change the Final Quote
Long gas line runs increase cost significantly: runs under 25 ft usually cost $15-$25/ft, 25-100 ft cost $25-$40/ft, and runs over 100 ft often run $40-$60/ft due to trenching or trenchless work. Higher boiler or furnace BTU capacity (e.g., 200k+ BTU) can push materials and regulator costs up by 20%-50%.
Venting condition thresholds: if existing chimney or flue can be reused, add $0-$500; if chimney liner or new direct-vent is required, add $800-$2,500.

Practical Ways To Reduce Oil-to-Gas Conversion Price
Keep scope minimal: choose a conversion kit for the existing burner when compatible ($300-$900) instead of full appliance replacement. Scheduling work in the contractor’s off-season can lower labor rates and expedite quotes.
Other cost controls: provide clear access to equipment, bundle with other home projects to negotiate, accept standard components rather than premium options, and get multiple written quotes specifying line items.
Regional Price Differences Across the U.S. and How They Affect Quotes
Prices vary by region: Northeast and West Coast averages are ~10%-30% higher than Midwest and South. A $3,800 average in the Midwest may be $4,200-$5,000 in the Northeast for the same scope.
Rural projects often add travel charges or minimums; expect $75-$200 minimum service fees and potentially higher per-foot gas-line costs for long utility tie-ins.
Common Add-Ons and Hidden Fees That Raise the Final Price
Typical add-ons include underground gas service tap ($500-$3,000), electrical work for new controls ($200-$800), and forced-air fan or circulation pump upgrades ($250-$1,200). Undisclosed fees often come from required safety upgrades or code-mandated chimney relining.
| Add-On | Low | Average | High |
|---|---|---|---|
| Underground service tap | $500 | $1,800 | $3,000 |
| Chimney liner / direct vent | $800 | $1,600 | $2,500 |
| Electrical connection | $150 | $400 | $800 |

Example B: 2,000 sq ft home, new gas furnace replacement, 60 ft run, chimney relining: $4,000-$6,500 total. Labor 12-18 hours.
Example C: 2,500+ sq ft home, high-BTU boiler, underground tank removal, 120 ft run with trenching: $6,000-$12,000 total. Labor 20-40 hours.
What To Ask For When Comparing Conversion Quotes
Request itemized bids that separate burner/kit, gas-line run per linear foot, venting work, tank removal, permits, and warranty. Insist on a written scope, timeline, and a clear payment schedule tied to milestones.
Ask about contractor gas-license, insurance, local inspection requirements, and whether the quote includes pressure testing and start-up calibration; these affect safety and final cost.
