Electric Furnace Installation Cost: What Homeowners Pay Nationwide
$3,200 is the national midpoint for a new electric furnace installed in a typical home. That includes the unit, the labor to install it, the electrical connections, and connecting it to your existing ductwork and thermostat. Compare that to a gas furnace at $2,800 to $6,500 and a heat pump at $5,000 to $14,000, and electric furnaces occupy the lower end of the installed-cost spectrum for central heating — though the operating cost story is more complex.
Electric furnaces deserve more attention than they get. They're simple, reliable, require almost no maintenance, have no combustion byproducts, and cost less to buy and install than any other central heating option. The reason they're not more popular is electricity cost: in most markets, electric resistance heating costs two to three times more to operate than gas heating. But in markets where electricity is cheap, or where a home has solar panels that offset the electricity cost, electric furnaces become a very practical choice.
How Electric Furnaces Work and Why They're Different
An electric furnace is simpler mechanically than any other forced-air heating system. It uses electric resistance heating elements — essentially large versions of the element in your toaster or baseboard heater — to heat air that's then distributed through your duct system by a blower. There's no combustion, no flue, no gas line, no heat exchanger.
This simplicity is a real advantage. Electric furnaces have fewer moving parts than gas furnaces, no combustion-related failure modes, and no carbon monoxide risk. They typically last 20 to 30 years — longer than the 15 to 20-year lifespan of a typical gas furnace.
The efficiency of an electric furnace is 100 percent by definition: all the electricity that goes in gets converted to heat. That sounds better than a gas furnace at 80 to 98 percent efficiency, but the math has to include the cost of the fuel. When electricity is 3 to 4 times more expensive per BTU than natural gas (as it is in most US markets), a 100 percent efficient electric system costs more to run than an 80 percent efficient gas system.
The situations where electric furnaces make the most sense: homes in mild climates where the furnace runs fewer hours per year; homes without existing gas service where running a gas line would add $500 to $2,000 in upfront costs; all-electric homes where the electric panel is already sized for high electrical loads; homes with solar panels that offset heating electricity cost; and homes in markets where electricity is relatively inexpensive (Pacific Northwest hydro power, for example).
What Electric Furnace Installation Costs
Unit cost is the primary variable, driven by heating capacity (measured in kilowatts or BTUs) and features.
A 15-kilowatt electric furnace — appropriate for a 1,000 to 1,500 square foot home in a mild climate — costs $500 to $1,200 for the unit itself. Installed, with labor and electrical work, the project runs $1,800 to $3,500.
A 20-kilowatt unit, appropriate for a 1,500 to 2,500 square foot home, costs $700 to $1,500 for the unit. Installed, the project runs $2,200 to $4,200.
A 25-kilowatt unit for larger homes runs $900 to $2,000 for the unit. Installed, $2,800 to $5,000.
Electric furnace installation almost always requires dedicated electrical capacity. A 15-kW furnace draws roughly 62 amps at 240 volts — that requires a dedicated 80-amp circuit. Larger units draw proportionally more. Homes with 100-amp panels may need panel upgrades before an electric furnace can be installed, adding $1,500 to $3,500 to the project cost.
| Item/Type | Low Cost | Average Cost | High Cost |
|---|---|---|---|
| 15-kW electric furnace (installed) | $1,800 | $2,800 | $4,000 |
| 20-kW electric furnace (installed) | $2,200 | $3,500 | $5,000 |
| 25-kW electric furnace (installed) | $2,800 | $4,200 | $6,500 |
| Panel upgrade (if needed) | $1,500 | $2,500 | $4,000 |
| Gas furnace for comparison (installed) | $2,800 | $4,500 | $7,500 |
| Heat pump for comparison (installed) | $5,000 | $9,000 | $15,000 |
City-by-City Cost Comparisons
Electric furnace installation costs vary by market through labor rate differences. In Seattle and Portland, where electric furnaces are most common due to relatively inexpensive hydroelectric power and mild winters, installed costs run $2,000 to $4,500. In Atlanta, where mild winters make electric furnaces viable, costs run $1,800 to $4,000. In Chicago, where labor rates are higher and the harsh winter climate raises capacity requirements (and thus unit cost), electric furnaces run $2,500 to $5,500 installed. In Phoenix, where winters are mild, installed costs run $1,800 to $3,800.
Electric Furnace vs. Heat Pump: The Modern Choice
The modern alternative to an electric furnace in most applications is a heat pump. Rather than generating heat through resistance heating, a heat pump moves heat from outdoor air into your home — it's essentially an air conditioner running in reverse, and it's two to three times more energy efficient than electric resistance heating.
A heat pump that delivers 3 units of heat energy for every 1 unit of electrical energy costs half to one-third as much to operate as an electric furnace of the same capacity. The federal Inflation Reduction Act provides a 30 percent tax credit for qualifying heat pump installations, making the upfront cost difference between heat pumps and electric furnaces smaller than it used to be.
For new installations in mild to moderate climates, heat pumps are almost always the better long-term choice despite their higher upfront cost. Electric furnaces make most sense as replacements for existing electric resistance systems where the infrastructure is already in place and the heating hours are limited.

Getting two or three quotes from local contractors gives you both price comparison and an education in what each system type would actually mean for your home's operating costs.
Frequently Asked Questions
How long do electric furnaces last compared to gas furnaces? Electric furnaces typically last 20 to 30 years due to their mechanical simplicity — no combustion, no heat exchanger, fewer failure-prone components. Gas furnaces typically last 15 to 20 years. The longer lifespan of electric units is one factor in the total cost comparison.
Is an electric furnace safe compared to gas? Electric furnaces have no combustion byproducts and no carbon monoxide risk. They're considered safer than gas furnaces from a combustion-related standpoint. The primary safety consideration for electric units is electrical — proper circuit sizing and installation are essential.
Do electric furnaces qualify for any tax credits? Standard electric resistance furnaces do not qualify for the federal heat pump tax credit. High-efficiency electric heat pumps do qualify for the 30 percent IRA credit through 2032. If you're choosing between an electric furnace and a heat pump, the tax credit significantly changes the upfront cost comparison.
What's the operating cost difference between electric and gas heating? In most US markets, electric resistance heating costs 2 to 3 times more per BTU than natural gas heating. A home that spends $800 per year on gas heat would spend $1,600 to $2,400 heating with electric resistance. In markets with inexpensive electricity (Pacific Northwest, Southeast with TVA power), the gap is narrower.
Can I install an electric furnace in any home? Any home with adequate electrical capacity can use an electric furnace. The main constraint is panel capacity — larger electric furnaces draw 60 to 100+ amps and require dedicated circuits that older homes may not have. A panel upgrade may be necessary, which adds to the project cost.
