Oil-to-gas boiler conversion in Fairbanks. What it actually costs, and what it actually saves.

In the initial consultation, we evaluate your existing boiler, its age and condition, and whether it's a candidate for a burner conversion or needs full replacement. We also check whether gas service reaches your property, and if it doesn't, what extending it would involve.

Gas line and venting evaluation comes next. We assess the piping route from the service entry to the mechanical room, and we check what your current venting setup can and can't support for a gas-fired system.

If there's an oil tank on the property, we evaluate it for removal, whether it's above ground or buried, and flag any signs of a past leak that would need remediation before the tank comes out.

Installation is the core of the job: the burner conversion or new boiler goes in, gas piping is run and pressure-tested, venting is completed or modified, and the old tank is removed or decommissioned according to code.

Every conversion ends with a final walkthrough and testing. We verify combustion, check for gas leaks at every connection, confirm proper venting, and test the system through a full heating cycle before we call the job done.

A typical conversion, once gas service is already at the property, takes one to three days depending on whether it's a burner conversion or a full boiler replacement. Extending gas service to a property that doesn't have it adds time that depends on the utility's scheduling, not on our crew.

Conversion cost varies more than almost any other plumbing or heating job, because it depends heavily on what's already in place at your property.

Factors that affect the price:

• Whether gas service already reaches your property, or needs to be extended by the utility
• Whether your existing boiler can accept a burner conversion or needs full replacement
• Venting changes required to meet gas code
• Oil tank removal, and whether it's above ground or buried
• Gas line routing and length from the service entry to the mechanical room

We give you a firm, upfront price before any work begins, based on what your specific property needs. We don't quote a generic number without seeing the system first, because the range between a simple burner conversion and a full replacement with new gas service is wide enough that a one-size estimate wouldn't be honest.

On the savings side, the national picture gives a useful reference point even though local rates differ from the national average. The U.S. Energy Information Administration's most recent Winter Fuels Outlook estimates that a household heating primarily with natural gas will spend roughly $686 over the 2025 to 2026 winter season, compared to roughly $1,749 for a household heating primarily with heating oil, a difference of more than two to one. Fairbanks doesn't sit on the standard Lower 48 natural gas grid, since local gas is supplied by pipeline and trucked LNG rather than a national pipeline network, so local rates and the exact size of the gap will differ from the national figure. But the underlying mechanics hold here too: heating oil prices track the global crude market and can swing sharply within a single season, while gas pricing tends to move more gradually.

The Fairbanks North Star Borough has also codified a voluntary heating oil to natural gas or propane conversion assistance program, subject to available funding, for properties in the borough's air quality nonattainment area. Program funding and rebate amounts change based on what the Borough Assembly appropriates in a given year, so we recommend checking directly with the Borough's air quality division for current eligibility and rebate amounts before budgeting around it.

We assess before we quote. Every conversion starts with an honest look at your existing boiler and venting, not an assumption that a full replacement is automatically the answer. If a burner conversion is the right call for your system, that's what we recommend.

We handle the full scope. Gas piping, venting changes, oil tank removal, and permitting all fall under one job with one crew, instead of coordinating separate contractors for each piece.

Licensed for the work that requires it. Boiler conversion touches mechanical, gas, and plumbing code. Our technicians hold the licensing Alaska requires to perform all of it.

Upfront pricing before work starts. You approve a firm number before installation begins, based on an actual assessment of your property, not a placeholder estimate.

The Done Right Guarantee. Every conversion is backed by our guarantee. If something isn't right, we come back and correct it at no additional cost.
