Oil furnaces are safer than natural gas furnaces because they do not release dangerous carbon monoxide and cannot catch fire from a gas leak. Oil furnaces also operate more quietly, creating a more relaxing living environment. While these furnaces have some advantages, they can be expensive to replace or install.
We aim to provide homeowners like you with the most accurate oil furnace cost information possible, so we rely on actual construction material databases and get our information straight from the manufacturer. That way, you’ll know what to expect even before you contact one of the best HVAC companies for a quote.

How Much Does It Cost To Install an Oil Furnace?
Oil furnaces cost between $6,425 and $9,175 to install. This national average includes the oil furnace, installation fees, and old furnace removal. If you install a new thermostat, replace ductwork, or install home air quality systems, your installation costs will be higher.
|Low Cost||Average Cost||High Cost|
How Do Costs Differ By Oil Furnace Type?
One of the most important cost factors is the efficiency of the furnace — the more efficient your furnace is, the more expensive it’ll be. However, the extra cost of a more efficient furnace will result in greater energy savings in the long run. So if you plan to live in your home long term, it’s worth it to pay more now to save later.
The efficiency of an oil furnace is measured by its annual fuel utilization efficiency, commonly known as the AFUE rating. This percentage tells you how efficient your oil furnace will be over time. New furnaces have AFUE ratings of 80% or more — the higher the percentage, the more efficient your furnace will be.
Standard furnaces have AFUE ratings between 80% and 89%, but high-efficiency furnaces have AFUE ratings of at least 90% or more. The most energy-efficient oil furnaces reach 97% efficiency. On average, the most efficient oil furnaces cost between $6,000 and $9,175, while you’ll pay between $3,500 and $7,500 for a standard efficiency furnace.
|Oil Furnace Type||Low Cost||High Cost|
|Standard Efficiency (80% – 89%)||$3,500||$7,500|
|High-Efficiency (90% – 97%)||$6,000||$9,175|
Standard Oil Furnace
If your current furnace broke down unexpectedly and you need a quick, affordable replacement, then a standard oil furnace is the way to go. Furnaces with an 80% to 89% AFUE rating still have good energy efficiency and will probably save you money on your energy bills compared to your old furnace. Standard efficiency oil furnaces cost between $3,500 and $7,500.
Standard oil furnaces are ideal if you live in a warmer state and don’t have cold winters. Since you only use your heating system a few months out of the year, you don’t have to spend the extra money for the most efficient furnace. But if you live in colder regions and use your furnace half the year, this type may not be right for you.
High-Efficiency Oil Furnace
High-efficiency oil furnaces cost, on average, between $6,000 and $9,175. These furnaces may cost more up-front, but you can save more than $1,275 in lifetime energy costs if you buy a more efficient furnace, according to the Department of Energy. If you live in a state that gets heavy snow and freezing temperatures, you’ll especially want to invest in an efficient furnace — you’ll save money every month you use it.
If you’re worried about the total cost of this more expensive furnace, ask about local rebates and tax credits. For oil furnaces, you can get a $150 IRS tax credit and up to $600 in rebates. After these savings, your energy-efficient furnace may not be much more than a standard efficiency furnace.
How Does Home Size Affect Oil Furnace Pricing?
The bigger your home, the larger your furnace will need to be. Larger homes require more forced air to heat each space and maintain a consistent internal temperature. For example, if you live in a 1,000-square-foot home, your furnace may cost between $6,425 and $7,420. If you live in a 3,000-square-foot home, your oil furnace might cost between $7,085 and $9,175.
|BTU||Home Square Footage||Low Oil Furnace Cost||High Oil Furnace Cost|
|55,000 BTU||1,000 sq. ft.||$6,425||$7,420|
|80,000 BTU||1,500 sq. ft.||$6,680||$7,650|
|100,000 BTU||2,000 sq. ft.||$6,700||$7,685|
|130,000 BTU||2,500 sq. ft.||$6,610||$8,075|
|150,000 BTU||3,000 sq. ft.||$7,085||$9,175|
Which Factors Impact Oil Furnace Cost Estimates?
The square footage of your home is just one factor of many that affect your oil furnace replacement costs, and you can expect several other factors to affect it, namely:
- British thermal units (BTU)
- Oil furnace brand
- Old furnace removal
- Additional installation costs
British Thermal Units (BTU)
|BTU||Low Oil Furnace Cost||High Oil Furnace Cost|
The British thermal unit (BTU) is the most common unit of measurement for HVAC equipment and refers to how much heat your oil furnace can produce. For furnaces, having a higher BTU means the unit has more heat capacity. You’ll pay $6,425 for a smaller 55,000 BTU unit, but you could pay $9,175 or more for an oil-heating furnace with 150,000 BTUs.
The bigger your home, the more BTUs you’ll need to heat it properly. You’ll also need to consider the height of your ceilings, the quality of home insulation, the size of your windows, and — most importantly — your geographic location.
Where you live plays a major role in furnace size because your furnace needs to work significantly harder to keep your home warm when the temperatures reach below freezing. If you live in northern states, you can expect to pay more for a larger oil furnace. But if you live in a warmer region, you can get away with fewer BTUs.
To estimate how many BTUs you’ll need, check out the average number of BTUs needed per square foot by region:
- 20 BTU to 30 BTU: Hot climates (Florida, Texas, and other Gulf Coast states)
- 25 BTU to 35 BTU: Warm climates (California and Southeast states)
- 30 BTU to 45 BTU: Moderate climates (Lower Midwest and Mid-Atlantic states)
- 45 BTU to 55 BTU: Cold climates (Mountain regions)
- 50 BTU to 60 BTU: Freezing climates (Upper Midwest and Northeast)
Oil Furnace Brand
|Furnace Brand||Average Unit Cost|
|Armstrong||$2,500 – $7,300|
|Bryant||$3,000 – $7,000|
|Carrier||$3,000 – $6,000|
|Kerr||$4,500 – $8,000|
|Lennox||$3,000 – $6,500|
|Rheem||$2,800 – $7,200|
|Thermo Pride||$3,500 – $6,500|
|Trane||$2,500 – $6,000|
The brand of furnace you choose will also affect your total cost. As you can see from the table above, the cost of different brands can differ by $1,000 or more. So pay attention to which brands your HVAC contractor offers.
Every heating, ventilation, and air conditioning contractor works with different brands, so it’s always a good idea to get several quotes before you settle on one. For example, you may get a quote for a Trane oil furnace for $6,000 but another for a Bryant furnace for $7,000. In this scenario, if you choose the Trane furnace over the Bryant furnace, you will save $1,000.
Old Furnace Removal
|Removal Type||Average Cost|
|Furnace under 120 MBH||$250 – $645|
|Furnace over 120 MBH||$335 – $645|
If you need to remove and dispose of your old furnace, that fee is usually lumped into labor costs — but some HVAC contractors will list it separately. Most residential furnaces are under 120 MBH (or 120,000 BTUs), so you can expect to pay between $250 and $645 to dismantle and remove your old furnace. But if you have a larger home and a larger furnace, you’ll likely pay $335 to $645 to remove it.

Additional Installation Costs
Any time you replace an older system or appliance in your home, you may find problems that need to be fixed or updates that need to be made. Additionally, furnace replacement is the best time to replace air filters, thermostats, and other outdated home systems.
- Ductwork replacement: Ductwork replacement costs between $15 and $40 per linear foot. The total amount you’ll pay for new ductwork depends on how much you need to install, but you can expect the total to be between $2,500 to $6,600.
- HEPA air purifier: If you want to improve your home’s air quality, you may install an in-home air filtration system. Some of these systems cost as little as $300, but most quality HEPA air purification systems cost between $2,000 and $4,000 for the unit and installation.
- Humidifier: Since you’ve already booked an HVAC crew, it’s a good time to install a humidifier in your home, too. These systems add water to the warm air as it leaves the furnace, which combats dry air and makes your home more comfortable in the winter. A humidifier typically costs between $800 and $1,100 for the unit, plumbing, and installation.
- Permits and inspections: In many states, you must pass an inspection and get a permit to install new HVAC systems. These permits and inspections cost between $50 and $300 on average.
- Thermostat installation: If you’re upgrading your old furnace, you may also want to give your thermostat a makeover. You can pay as little as $50 for a new programmable thermostat or more than $300.

Are oil furnaces being phased out?
In the United States and other countries, several initiatives aim to phase out heating systems that rely on fossil fuels, including oil and natural gas furnaces. The trend is toward electric furnaces because these furnaces do not lose energy during conversion. However, this initiative applies primarily to new construction, so you do not have to completely replace your heating system yet if your oil furnace breaks down.
Are oil furnaces safe?
Oil furnaces are perfectly safe to install. Unlike propane furnaces, oil furnaces do not use natural gas as their fuel source. This means you will not need to worry about carbon monoxide, fires, and explosions.
How much does a new furnace save on your heating bill?
According to the Department of Energy, an oil furnace with 95% AFUE will save you more than $1,275 and a furnace with 99% AFUE will save you more than $1,550 per year. For a furnace with an 80% AFUE rating, your lifetime energy cost is $8,075, while that cost would be $6,525 for a 99% AFUE furnace.
