New Furnace Installation Cost

Installing a new furnace costs anywhere from $1,000 to $8,000 or more. But it breaks down into labor, unit cost and equipment. Your bill breaks down roughly like this:

  • Unit: 50-75%
  • Labor: 20-30%
  • Equipment, permits and removal: 15-25%

Labor Costs for Furnace Installation

You’ll pay between $150 to $500 for professional labor to install a furnace. You can expect to pay $50 to $100 per hour for a licensed furnace installer, along with up to $50 per hour per additional team member. The cost will depend on your current set-up and whether you need to repair or install new ductwork.

Cost to Install Furnace and Ductwork

Installing ductwork costs or $3,000 to $5,000 or more. Most furnaces won’t work properly if the ductwork, vents, or various type of filters aren’t installed or adjusted properly for the new heating system. Duct repair costs $1,000 to $5,000. Besides accessibility and repairs after the install, other factors that affect cost include the number of:

  • Stories in a house.
  • Intake or output vents.
  • Temperature-control zones.

Permits & Inspections

Building permits cost from $400 to $1,500 depending on your location. Most places include inspection fees of $100 in the permit price. These ensure that the equipment operates safely. Some local gas providers offer free inspections. Shop around before settling on an inspector.

Oil Burner Heating Unit Cost

An oil burning unit costs $1,800 to $6,000, not including labor.

When oil was cheap, oil furnaces dominated the market, particularly in the northeastern United States. As oil prices rose, the federal government gave rebate incentives for homeowners to convert to natural gas. Eventually, they became the dinosaurs of the heating market. Unlike other heating options, they require storage tanks. But this gives you the option of buying large amounts at one time, getting rid of the monthly heating bill.

ProsCons
More environmentally friendly than natural gasHigh fuel costs
On-site storage of fuelReleases carbon monoxide

Electric Heater Cost

Electric heaters cost $500 to $3,000 for an entire home. It’s the cheapest way to go in terms of initial costs. But it’s the most expensive to run.

ProsCons
High efficiency.High monthly cost.
Safe and low maintenance.Takes a long time to heat a space.
Low initial installation cost.

Coal Furnace Cost

Coal furnaces run $3,000 to $10,000 and work much like a wood or pellet stove. They burn coal in a central chamber, heating the air above it. Most come with fans to then blow the air throughout ductwork.

  • Installing a wood stove costs $900 to $3,500 but doesn’t connect to ducts easily and requires constant cleaning. Some standalone coal furnace types work like a wood burning stove or fireplace, without the aid of ducts or fans.

ProsCons
Less expensive to run.High initial installation price.
Burns cleaner than wood without the need for a chimney.Must feed the boiler every 12 hours.
Completely off-grid compatible.Regular cleaning of ash required.

Heating System Costs by Size

Furnace BTUsSquare FeetTotal Average Cost
40,000-60,000700-1500$2,000-$3,000
80,000-100,0001,300-3,000$2,600-$4,200

125,000-150,0002,000-5,000$3,300-$6,500

The average home requires around 100,000 BTUs of heating at a cost of $3,000 to $4,500. Keep in mind that the AFUE rating affects the actual heating capacity of your furnace. For example, if your furnace has a rating of 80%, you’ll only get 80,000 BTU’s from a 100,000 BTU furnace.

What Size Furnace Do I Need?

Homes typically require 30 to 60 BTUs per square foot. To figure out the average heating capacity that a home requires, calculate the square footage of the home. Whether a home needs more or fewer BTUs depends on the climate zone where the home is located. To find the cost savings of an energy star rated high efficiency furnace, you can figure your savings by multiplying your monthly electric bill by the efficiency difference between your old and new furnace.

For example, if you have a 70% efficiency furnace and you replaced it with a 97% efficiency model, you’d have about 35% efficiency upgrade. Now just multiply that by your monthly bill. Divide the cost of the new unit by that figure and that’s how many months it’ll take to pay off.

When a pro comes to your home to quote a heating system installation, they’ll do some load calculations to help determine what size (BTUs) you’ll need. A BTU or British Thermal Unit is how much energy it takes to raise one pound of water one degree Fahrenheit. Load calculations depend on several factors, including:

  • AFUE Rating. AFUE, or Annual Fuel Utilization Efficiency, of 80-90 means 80%-90% efficiency. So, a 100,000 BTU furnace with an AFUE of 80 would only put out an effective 80,000 BTUs. You can find the AFUE on a sticker on all furnaces.
    • Standard Efficiency = 80 to 89 AFUE
    • Mid Efficiency = 90-95 AFUE
    • High Efficiency = 96+ AFUE
  • Climate Zone. Recent changes to the ASHRAE climate zone map helps a pro determine the heating needs of your region.
  • Livable Square Footage. The size of your home makes a huge impact on the size of your furnace.

Crawl Space vs. Attic Furnace Prices

The cost differences between putting one in your attic or crawlspace depend heavily on which makes the most sense for the configuration of your home.

How much does it cost to relocate a furnace in a house?

Relocating a furnace within a home can run you anywhere from $1,000 to $20,000 or more.

  • On the low end, relocation might be as simple as placing the new unit a few feet from the old when finishing a basement. The simplest move might only mean adding a few feet of ductwork.
  • On the high end, it might mean moving the entire system from a basement to an attic. This might require extensive construction with added duct work, drywall and new electrical circuits or gas lines.

How much does it cost to convert a heat pump to a gas furnace?

Converting a heat pump to a gas furnace requires removal of the old pump and installing a new furnace for $1,000 to $5,500. The new system should use your existing ducts with no problem, but it’s never a bad idea to have them inspected by a duct cleaning service near you.

How much to replace a boiler with a furnace?

Replacing a boiler with a furnace tends to run in the $2,000 to $6,000 range. Just removing the old system runs $500 to $1,000+. The accessibility, size and complexity of your existing setup accounts for most of the price difference.

What’s the average cost of converting from oil to electric heat?

The average cost to convert from oil to electric heat runs in the $2,000 to $5,000 range. Most homeowners spend $4,000 for a new furnace.

How long does a gas furnace usually last?

Return to Top

When should I replace my furnace?

Replace your furnace every 20 years on average. However, if you’re looking to replace it for energy efficiency reasons, be sure to look into adding insulation, replacing windows and doing a home energy audit.

What is the best gas furnace for my home?

The best gas furnace for your home would probably be a centralized system with a fan. But without a site visit, it’s hard to determine the size, where to locate it and the specifics of your climate. Contact an HVAC pro near you for a free estimate.

What's the difference between a gas, oil and electric furnace?

Understanding different furnace types isn’t easy. The difference between gas, oil and electric furnaces lies in the fuel source and how fast they can heat your home.

  • Electricity, either from the local power grid or solar panels, is cleaner but takes longer to heat a space.
  • Gas and oil burn propane, natural gas or oil to heat air being pushed through your ducts.

What's the difference between a boiler, furnace and heat pump?

  • Boiler uses electricity or gas to heat water. The water then moves through your home, heating radiators in each room.
  • Furnaces have a central location that heats the air being pushed through your home.
  • Heat pumps use a refrigerant to move heat from the air, water or ground outside your home. It then transfers that heat into your house. Ductless mini-split heat pumps cost$1,300-$8,000 and are the most common and affordable type. Geothermal is much more efficient.
