Key Factors That Influence Price
Furnace Size (kW) And Home Load
Electric furnaces are rated in kilowatts (kW), which convert to BTU output (1 kW ≈ 3,412 BTU/h). Larger homes and colder climates need higher output. A proper Manual J load calculation is the gold standard for sizing.
| Home Size (Approx.) | Common Electric Furnace Size | Installed Price Range |
|---|---|---|
| 800–1,200 sq. ft. | 8–12 kW | $3,000–$5,000 |
| 1,300–1,800 sq. ft. | 12–15 kW | $3,500–$6,000 |
| 1,900–2,400 sq. ft. | 15–20 kW | $4,500–$7,500 |
| 2,500–3,000+ sq. ft. | 20–25+ kW | $5,500–$9,000+ |
Why it matters: Oversizing increases upfront cost and can reduce comfort. Undersizing leads to long run times and cold rooms. Insulation and windows influence load as much as square footage.
Electrical Panel And Wiring
Electric furnaces draw significant current and usually need dedicated 240V breakers and heavy-gauge wiring. Larger units may require multiple breakers or a subpanel. If the home has a 100A service and other large loads, a 200A upgrade may be required.
- Dedicated Circuitry: $300–$1,200 for breakers and wiring runs
- Subpanel: $400–$1,000 when space is tight
- Service Upgrade To 200A: $1,500–$4,000+, depending on utility and site
Electric codes and permits apply. A licensed electrician typically partners with the HVAC contractor on these upgrades.
Ductwork And Airflow
Replacing an electric furnace often includes minor duct transitions. If static pressure is high or ducts leak, contractors may recommend sealing, resizing, or adding returns.

- Minor Modifications: $400–$1,000 for transitions and sealing
- Balancing & Additional Returns: $300–$1,500
- Full Duct Replacement: $2,000–$8,000+, depending on layout and access
Better airflow reduces noise, improves comfort, and protects blower motors. It can also lower fan energy use.
Location, Access, And Labor Rates
Labor costs are higher in major metros and coastal markets. Access complexity matters too. Attics, tight closets, and crawlspaces increase time and difficulty compared to open basements or garages.
- Easy Access (Basement/Garage): Lower labor time and cost
- Difficult Access (Attic/Crawl): Higher labor, possible lift costs
- Region: Urban coasts trend higher than Midwest/South
Brand, Features, And Warranty
Basic resistance furnaces are similar in heating efficiency, but differences exist in cabinet design, blower type, controls, and warranty. Premium brands may include ECM blower motors, better insulation, and quieter operation.
- Standard PSC Blower: Lower cost, higher energy use
- ECM/Variable-Speed Blower: Higher cost, quieter, lower fan energy
- Warranty: 10-year parts is common; labor warranties vary by contractor
Electric Furnace Vs. Heat Pump Vs. Gas: Cost And Operating Cost
The upfront cost of an electric furnace can be appealing. However, operating cost varies widely by fuel prices and climate. Heat pumps often deliver the lowest heating cost in moderate climates.
| System Type | Typical Installed Cost | Annual Heating Cost Example | Notes |
|---|---|---|---|
| Electric Furnace (Resistance) | $3,000–$7,500 | $1,800–$3,000 | 100% efficient resistance; cost depends on kWh rate |
| Air-Source Heat Pump | $6,500–$13,000 | $700–$1,500 | 3x+ efficient in mild weather; needs air handler |
| Natural Gas Furnace | $5,500–$11,000 | $600–$1,200 | Low fuel cost where gas available; needs venting |
Example assumes a moderate climate with a seasonal heating need of roughly 50 million BTU and average U.S. energy prices. Actual results vary by climate zone, home efficiency, and local utility rates.
Key takeaways: In regions with high electricity prices or very cold winters, an electric furnace can cost more to run than gas. A modern heat pump can cut electric heating use by two-thirds compared to resistance heat, often paying back higher upfront cost within a few winters.
How To Estimate Your Electric Furnace Replacement Cost
A structured approach can narrow the budget range and reduce change orders after work starts.
- Determine Heating Load: Ask contractors for an ACCA Manual J calculation. It accounts for insulation, windows, air leakage, and climate.
- Check Electrical Capacity: Confirm panel size and available breaker spaces. Share other large loads (EV charger, range, dryer, AC).
- Assess Ducts: Request static pressure testing and visual inspection. Note comfort issues and noisy runs.
- Select Features: Decide on ECM blower, filter cabinet, and thermostat type. These choices affect comfort and energy use.
- Request Itemized Quotes: Compare equipment model numbers, labor scope, electrical work, permits, and warranties.
- Plan For Permits & Inspection: Ensure the bid includes them; many jurisdictions require permits.
Pro tip: If central air or a heat pump upgrade is planned soon, coordinate the air handler/furnace now to avoid rework.
Ways To Save Without Cutting Corners
- Bundle Projects: Combine furnace replacement with AC or heat pump installation to reduce labor overlap and get package pricing.
- Choose An ECM Blower: Saves fan energy and improves comfort. The premium often pays back through quieter, smoother airflow and lower kWh for circulation.
- Shop Shoulder Seasons: Spring and fall can bring better availability and pricing than peak winter.
- Optimize Ducts, Don’t Overdo: Targeted sealing and balancing can solve comfort issues without full replacement.
- Consider A Heat Pump: In many climates, a heat pump’s lower operating cost offsets its higher upfront price within several years.
- Ask About Financing: Low-APR or utility on-bill financing can spread costs while preserving cash.
Rebates & Credits: Electric resistance furnaces typically do not qualify for major federal tax credits. However, many federal, state, and utility incentives support heat pumps, weatherization, and sometimes electrical panel upgrades when enabling a qualifying heat pump.
When Replacement Makes Sense
While resistance furnaces maintain their efficiency over time, replacement can still be justified by reliability, safety, or comfort improvements.
- Age & Reliability: Frequent failures on a unit 15–25+ years old justify replacement.
- Safety & Code: Damaged wiring, overheating, or repeated tripping should be addressed immediately.
- Comfort Gaps: Undersized or poorly ducted systems can be replaced with correctly sized equipment and improved airflow.
- Air Handler Upgrade: A new ECM blower and tighter cabinet can reduce noise and drafts.
- Electrification Or Conversion: Switching to a heat pump while replacing the air handler can cut operating costs substantially.
Installation Timeline And What To Expect
A straightforward replacement often completes in a day. Projects with electrical or duct upgrades typically take 1–2 days, sometimes more.
