Replacing a gas furnace with electric heat typically costs $4,000-$12,000 when the job includes removing the furnace, installing electric equipment, and making necessary electrical changes. The final price depends on whether the home gets a resistance electric furnace or a heat pump, whether the panel can handle the load, and how much ductwork or wiring needs work.

What a gas-to-electric furnace conversion usually costs
A standard conversion to an electric resistance furnace commonly totals $4,000-$12,000. The low end generally covers a straightforward swap in a home with usable ducts and adequate electrical service; the high end can include a panel upgrade, new circuits, difficult removal, or duct modifications. A heat pump conversion costs more initially, often $7,000-$18,000, but provides air conditioning and can use less electricity than resistance heat.
For a typical 1,500- to 2,000-square-foot home, budgeting about $7,500-$10,000 for a resistance conversion is a practical starting point. Local labor rates, climate, equipment capacity, and electrical condition can move an estimate substantially. Assumptions: existing ductwork is serviceable, access is ordinary, and pricing reflects common U.S. contractor-installed equipment.
How furnace removal, wiring, and equipment shape the quote
Contractor proposals may combine several trades and materials. These ranges show common line items; they are not all mandatory on every project.
| Quote item | Typical price | Pricing basis | What it covers |
|---|---|---|---|
| Electric furnace | $1,000-$3,500 | Equipment | Heating unit, often 10-20 kW residential capacity |
| Installation labor | $1,000-$2,500 | $75-$150 per hour | Set, connect, test, and commission equipment |
| Electrical circuit and wiring | $500-$2,000 | Project total | Dedicated circuits, breaker, and wiring adjustments |
| Panel or service upgrade | $1,500-$5,500 | Project total | Higher electrical capacity when needed |
| Gas furnace removal and disposal | $250-$800 | Project total | Disconnect, haul-away, and disposal |
| Permit and inspection | $100-$500 | Permit total | Local electrical or mechanical approvals |
Electrical work is often the biggest variable after equipment selection. Ask whether the estimate includes permits, gas-line capping, disposal, thermostat connection, and final inspection, rather than comparing equipment prices alone.
How panel capacity and furnace size change the estimate
Electric furnaces draw substantial power, so an existing gas-heated home may need more electrical capacity. A 10-kW unit draws about 42 amps at 240 volts, while a 20-kW unit draws about 83 amps, before accounting for other household loads. An electrician may find that a dedicated circuit is enough, or that a panel or service upgrade is necessary.
Home size alone does not determine furnace capacity or electrical cost. A 1,200-square-foot well-insulated home may need less heat than a larger, draftier one; a heat-load calculation is more useful than simply matching the old furnace. Long wire runs, finished walls, an undersized panel, or a 200-amp service already near capacity can add hundreds to several thousand dollars.
Which costs less to install, resistance heat or a heat pump?
An electric furnace usually has the lower installation price: roughly $4,000-$12,000 for a gas-to-electric conversion. A ducted heat pump often costs $7,000-$18,000 because the job adds an outdoor compressor and refrigerant lines, and may require an air handler or controls. A heat pump moves heat rather than generating it directly, so operating costs can be lower in many climates, although cold-weather performance and local electric rates matter.
Compare installed price with expected energy use, not equipment price alone. A dual-fuel setup that keeps the gas furnace and adds a heat pump is a separate option, typically costing more than a basic furnace replacement. Request estimates for the same heating capacity and included work, and confirm whether cooling equipment is part of the heat-pump quote.
Why electrical labor and installation time vary by home
A simple furnace swap may take one workday, while a conversion involving new circuits, panel work, or duct changes can take one to three days. Electrical work may require a separate licensed electrician, which affects scheduling and labor charges. Typical HVAC labor runs about $75-$150 per hour, with regional differences and minimum service charges influencing small jobs.
Clear access to the furnace and electrical panel can reduce labor time. Tight closets, attic or crawlspace equipment, inaccessible wiring, and repairs to finished surfaces can extend the project. Ask the contractor to state the expected crew size, workdays, and any separate electrical subcontractor charge.
How regional labor rates affect a conversion quote
Prices in high-cost coastal metros and major cities may run about 10%-25% above the national midpoint, while some rural and lower-cost markets may come in 5%-15% below it. These are broad comparisons, not guarantees: equipment availability, permitting rules, and the need for a service upgrade can outweigh the regional labor difference.
Compare at least two or three local, itemized estimates. Check that each quote specifies furnace capacity, electrical scope, removal, permit fees, warranty, and whether repairs to ducts or walls are included. A low bid that excludes panel work may not represent the lower final cost.
Which conversion add-ons should be priced separately?
Gas-line disconnection or capping may add about $100-$500, while duct sealing or minor repairs can add $300-$1,500. Major duct replacement can cost several thousand dollars and should be separated from the furnace conversion. A new thermostat may add $100-$500 installed; additional controls for a heat pump can cost more. Local permits and inspection charges vary by jurisdiction.
Have contractors identify optional work separately from code-required work. Ask whether the gas line will be permanently capped, whether old equipment disposal is included, and whether the quote accounts for condensate drainage on a heat pump. If the panel needs an upgrade, request the electrician’s scope and price in writing.
How to lower the gas-to-electric conversion price
Keep the project focused on necessary work: confirm duct condition before authorizing replacement, avoid oversized equipment, and select standard controls unless a feature has a clear benefit. If the electrical panel has adequate capacity, get that verified before assuming an upgrade is required. Scheduling outside peak heating demand may improve contractor availability, though timing does not guarantee a discount.
Ask for separate prices for a resistance furnace, heat pump, and any panel upgrade. Compare warranties, equipment efficiency, permit handling, and removal charges—not just the bottom line. Where a heat pump is under consideration, check current utility incentives and tax rules before budgeting them as guaranteed savings; eligibility and amounts can change.
