Furnace Replacement Cost in Rhode Island: 2026 Prices for Gas, Oil, and Conversions

Furnace replacement cost in Rhode Island for 2026: gas, oil, and high-efficiency prices, rebates and tax credits, add-ons, and oil to gas math.

Furnace Replacement Cost in Rhode Island: 2026 Prices for Gas, Oil, and Conversions

Furnace replacement in Rhode Island costs $5,500 to $9,500 for a standard-efficiency gas furnace, $7,500 to $13,000 for a high-efficiency condensing model, and $6,500 to $11,000 for an oil furnace. Those figures include removal of the old unit, the new furnace, basic venting, and permits, and they run 10% to 15% above the national average because of labor rates in Providence County and the age of the homes across the state.

About a third of Rhode Island homes still heat with oil, which is one of the highest shares in the country. That matters for cost because oil furnaces are more expensive to buy and install than gas, and because many homeowners replacing an oil furnace are weighing a conversion to gas or a heat pump at the same time.

Age is the other Rhode Island factor. A lot of the furnaces being replaced in Cranston, Warwick, Pawtucket, and Woonsocket are 25 to 35 years old, sitting in basements with old ductwork and chimneys that were never built for a modern appliance, and that adds work that a straight swap in a newer house would not need.

What a New Furnace Costs in Rhode Island by Type

An 80% AFUE gas furnace is the least expensive option and still common in older homes with masonry chimneys. Installed prices in Rhode Island run $5,500 to $9,500 in 2026, with the range driven by size, brand, and whether the existing flue can be reused.

A 95% to 98% AFUE condensing gas furnace runs $7,500 to $13,000 installed. The furnace itself costs $1,500 to $3,000 more than an 80% model, and the PVC venting through a sidewall plus the condensate drain add $500 to $1,500 in labor.

Oil furnaces run $6,500 to $11,000 installed. The equipment costs more, the burner needs a professional setup, and if the tank is over 20 years old or showing rust, replacing it adds $2,500 to $4,500 for an above-ground tank.

Propane furnaces, common in the western towns like Foster, Glocester, and Exeter where there is no gas main, price like gas furnaces with a few hundred dollars added for the conversion kit and regulator work.

Size and Efficiency Trade-Offs

A 1,500 square foot cape in Warwick typically needs a 60,000 to 80,000 BTU furnace, and a 2,500 square foot colonial in Barrington needs 80,000 to 100,000 BTU. Oversizing is a common mistake in Rhode Island because contractors match the old furnace instead of running a load calculation, and an oversized furnace short cycles and wears out early.

High efficiency pays back faster here than in milder states. A Rhode Island household burning 800 therms a year saves roughly $200 to $300 annually by moving from an 80% to a 96% furnace, which covers the price difference in six to ten years.

Brand moves the price less than people expect. The difference between a builder-grade furnace and a premium line from the same manufacturer is usually $800 to $1,500 installed, and the installer's skill matters more for longevity than the badge on the cabinet.

Rebates and Incentives That Cut the Price

Rhode Island Energy offers rebates for high-efficiency gas furnaces and boilers through its residential programs, and the amount varies by equipment tier and changes year to year. Rebates for qualifying condensing furnaces have run several hundred dollars, and the contractor should file the paperwork for you.

The federal tax credit for high-efficiency furnaces covers 30% of the cost up to $600 for units that meet the efficiency threshold. That credit stacks with the state rebate and applies whether you are replacing gas or oil.

Heat pumps get larger incentives. Rhode Island Energy and the state's Office of Energy Resources have offered heat pump rebates that reach into the thousands for whole-home systems, and the federal credit for heat pumps is 30% up to $2,000, which changes the math for anyone whose oil furnace is dying.

Financing through the Rhode Island Energy HEAT Loan program has offered 0% interest for qualifying efficiency upgrades, including furnaces, for terms up to seven years. Ask your contractor whether the equipment qualifies before you sign.

What Adds to the Bill in Rhode Island Homes

Chimney liners are the most common add-on. An 80% furnace vents into a masonry chimney, and Rhode Island's older chimneys often need a stainless liner at $1,500 to $3,500 to pass inspection, especially when a water heater is sharing the flue.

Ductwork in a 1920s house in Providence or a 1950s ranch in Cranston is often undersized, leaky, or asbestos-wrapped. Sealing and minor modifications run $500 to $1,500, and asbestos abatement on old duct insulation runs $1,500 to $4,000 and has to be done by a licensed abatement contractor.

Electrical work is a frequent surprise. A modern furnace needs a dedicated circuit and a proper disconnect, and adding one in an older panel runs $300 to $800, while a full panel upgrade runs $2,500 to $4,500.

Oil tank removal is its own line. Removing an old basement tank runs $500 to $1,200 in Rhode Island, and a buried tank with any sign of leakage triggers environmental testing and cleanup that can run into five figures.

Replacing Oil With Gas or a Heat Pump

Gas conversion makes sense when the main is on your street. Rhode Island Energy charges to run a service line from the street to the house, with the cost depending on distance and whether the utility waives it for new heating customers, and the interior piping adds $1,500 to $3,500.

A full conversion from oil to a condensing gas furnace, including the new service, piping, furnace, and tank removal, typically lands between $12,000 and $20,000 in Rhode Island. The operating savings versus oil have run $600 to $1,200 a year at recent fuel prices, so the payback is 10 to 15 years before rebates.

Heat pumps are the other path, and they are getting more attention in the state every winter. A cold-climate ducted heat pump replacing an oil furnace runs $12,000 to $22,000 installed, and with the state and federal incentives the net cost often beats a gas conversion for homes without a gas main nearby.

Many Rhode Island homeowners keep the oil or gas furnace as backup and add a heat pump for most of the season. That hybrid setup costs more up front but lets the cheaper heat source run whenever it is efficient, which in Rhode Island's climate is most of the winter.

Boilers are worth a mention because so many Rhode Island homes have radiators instead of ducts. A boiler replacement is a different job with different pricing, generally $7,000 to $14,000 for gas and more for oil, and a contractor quoting a furnace for a house with baseboard heat has misread the system.

Hiring a Furnace Installer in Rhode Island

Rhode Island requires a Pipefitter license for gas furnace installation and an Oil Heat license for oil equipment, and the contractor also needs a state contractor registration. The Department of Labor and Training and the Contractors' Registration and Licensing Board both have online lookups, and the license number should be on the estimate.

Three quotes is the right number, and each should include a load calculation, the exact model, the venting plan, the electrical work, and the permit fee. A contractor who quotes a furnace size over the phone without seeing the house is matching the old unit rather than sizing the new one.

Permits are required statewide for furnace replacement, and the inspection catches venting and combustion air problems that cause carbon monoxide issues. A contractor who skips the permit to save you $100 is skipping the inspection.

Timing affects both price and availability. Contractors in Rhode Island are slammed from November through February, and a furnace that fails in January gets replaced at whatever the schedule allows, while a planned replacement in May or September often comes with a discount and a choice of dates.
