An electric furnace costs $1,900 to $5,600 to replace, with a published national average of $3,750, per HomeGuide (February 2026)1. Angi and HomeAdvisor both publish an installation-labeled range of $2,247 to $8,116 with a $5,148 average, drawn from 11,869 verified projects on Angi23 — the two are corporate siblings, and matching figures alone don’t establish independent corroboration. The labels differ — HomeGuide’s headline is replacement scope, Angi and HomeAdvisor’s is installation — so the figures are presented with their labels attached. Everything below is the latest published data from each source.
Unit and labor split
HomeGuide splits the replacement total into $1,000 to $3,500 for the unit and parts plus $800 to $2,500 for installation labor1. Angi puts unit costs at $800 to $2,600 with larger units reaching $13,750, and labor at $800 to $2,500 for a new installation or $300 to $800 for a replacement2. HomeAdvisor publishes the same $800 to $2,600 unit range but caps larger models at $4,500 — a point where the siblings diverge, presented as published — and puts labor at $300 to $2,500 depending on job type, at $50 to $150 per hour plus $50 per hour for each added pro3. HomeGuide’s hourly rates run $75 to $150 per technician plus $30 to $50 per assistant, with 5 to 18 hours per job1.
Cost by home size
Angi and HomeAdvisor publish identical cost ranges by home size — corporate siblings, and matching figures alone don’t establish independent corroboration. (Their BTU labels differ on the largest row: 90,000 to 100,000 on Angi, 90,000 to 110,000 on HomeAdvisor23.)
| Home size (sq ft) | Size (BTU, per Angi) | Average cost (both) |
|---|---|---|
| Under 1,000 | 40,000 | $800–$2,600 |
| 1,000–1,500 | 40,000–55,000 | $900–$2,700 |
| 1,500–2,000 | 50,000–70,000 | $1,100–$2,800 |
| 2,000–2,500 | 70,000–90,000 | $1,200–$3,400 |
| 2,500–3,500 | 90,000–100,000 | $1,400–$4,500 |
HomeGuide’s home-size table prices unit and total replacement separately1:
| Home size (sq ft) | Unit cost (HomeGuide) | Total replacement (HomeGuide) |
|---|---|---|
| 1,300–1,600 | $700–$2,400 | $1,700–$5,100 |
| 1,600–1,900 | $800–$2,600 | $1,800–$5,300 |
| 1,900–2,200 | $1,000–$2,800 | $2,000–$5,500 |
| 2,200–2,600 | $1,200–$3,500 | $2,200–$6,200 |
| 2,600–3,200 | $1,300–$4,500 | $2,300–$7,200 |
Replacement vs. new installation
HomeGuide puts a replacement at $1,950 to $7,500 total against $4,100 to $13,200 for a new installation1. Angi and HomeAdvisor both publish $1,300 to $8,400 for a replacement and $4,700 to $19,100 for a new installation23. One transparency note: a second table on Angi’s page transposes those two labels, so the figures above follow the table that matches Angi’s own text, which says a new installation runs roughly three times a replacement2.
Add-ons and related work
Where the siblings match, the figures appear once. Dedicated electrical circuit: $500 to $2,000 (both)23. Ductwork: $35 to $55 per linear foot on Angi and HomeAdvisor23, against HomeGuide’s $25 to $55 per linear foot for replacement ductwork, $2,400 to $6,600 for new ducts, and $1,400 to $5,600 to replace old ducts1 — presented as published. Thermostat replacement: $100 to $250 (both)23 against HomeGuide’s $140 to $3501. Disposal of the old unit: $100 to $300 (both)23 against HomeGuide’s $150 to $4001. Electrical panel upgrade: $500 to $1,800 (both)23 against HomeGuide’s $1,300 to $2,5001. HomeAdvisor notes new installations take about four to 10 hours of labor3.
Operating costs
HomeGuide puts running an electric furnace at $130 to $180 per month or $1,600 to $2,200 per year1, while Angi and HomeAdvisor both publish $160 to $315 per month or $1,900 to $3,800 per year23 — presented side by side. Angi’s monthly-bill table by furnace size runs $250 per month for a 50,000-BTU unit up to $500 for 100,000 BTU2. HomeGuide adds that an electric furnace costs two to four times as much to run as gas — its own comparison, attributed1. See our gas furnace cost guide for the other fuel.
Sizing, lifespan and efficiency
Angi and HomeAdvisor both size electric furnaces at 30 to 35 BTUs per square foot in the warmest climates and 50 to 60 in the coldest23; HomeGuide publishes 20 to 60 BTUs per square foot depending on climate zone1. All three publishers put electric furnaces at an AFUE rating of 100 and a 20-to-30-year lifespan, with gas furnaces at 15 to 20 years on Angi and HomeAdvisor or 15 to 25 on HomeGuide — attributed figures123.
Brands and mobile homes
HomeGuide’s brand table: Goodman units at $700 to $900 ($1,100 to $3,600 installed), Direct Comfort at $650 to $850 ($1,650 to $3,550), King Electric at $1,400 to $5,600 ($2,400 to $8,300), Stelpro at $1,100 to $2,300 ($2,100 to $5,000), and Winchester at $1,100 to $1,600 ($2,100 to $4,300), with installed figures covering basic installation and existing connections1. For mobile homes, HomeGuide puts replacement at $950 to $3,000 for HUD-approved units of 35,000 to 70,000 BTU, with units alone at $450 to $1,5001.
Converting from gas or oil
HomeGuide prices converting a gas furnace to electric at $2,900 to $9,500, including $1,300 to $2,500 for electrical upgrades and $600 to $2,600 for the new unit, and converting from oil at $3,300 to $13,000 with tank and line removal adding $400 to $3,5001. HomeAdvisor’s figure for oil-to-electric conversion is lower at $1,800 to $6,200, framed as a budget for the new electric installation including removal and disposal — a scope difference worth noting, presented as published3.
Permits
Permit requirements and fees vary by municipality, so confirm with your local building authority; contractors typically handle the paperwork. For budgeting, Angi and HomeAdvisor both publish a permit estimate of $200 to $50023, while HomeGuide prices permits and inspections at $250 to $1,500 plus $50 to $350 for electrical permits when circuits, control wiring or thermostat work is involved1.

The bottom line
Budget $1,900 to $5,600 for an electric furnace replacement on HomeGuide’s figures, or $2,247 to $8,116 for an installation on the numbers Angi and HomeAdvisor both publish. Labor, ductwork, and electrical work decide the rest of the bill, and the running costs deserve as much attention as the sticker price: HomeGuide puts monthly operation at $130 to $180, while Angi and HomeAdvisor publish $160 to $315. Size the unit to your climate zone before comparing quotes.
