💡 Introduction: The Question Every Homeowner Asks
When I started shopping for an electric furnace, my first thought was simple: “How much is this going to cost me?”
After hours of research and phone calls, I realized there’s more to that question than just a sticker price. Sure, you can find a furnace online for under $1,000 — but what about the installation, the energy bills, and the maintenance over 20+ years?
The truth is, the real cost of owning an electric furnace is a combination of upfront investment, installation labor, running costs, and long-term savings.
In this guide, I’ll break it all down — with real numbers, real comparisons, and a few lessons from my own experience upgrading to an efficient, all-electric home heating system.
⚙️ 1. Equipment Costs: How Much Does an Electric Furnace Itself Cost?
Let’s start with the base cost — the furnace itself.
Modern electric furnaces are actually some of the most affordable central heating systems on the market. The total equipment price depends on size (kW rating), brand, and efficiency features.
🏷️ Average Price Ranges (as of 2025):
| Furnace Size (kW) | Typical Home Size | Estimated Price (Unit Only) |
|---|---|---|
| 10–12 kW | 1,000–1,500 sq. ft. | $800–$1,200 |
| 15–20 kW | 1,500–2,000 sq. ft. | $1,400–$2,000 |
| 25 kW+ | 2,000–2,500 sq. ft. | $2,200–$2,800 |
Key Price Drivers:
-
Blower type: Variable-speed models cost more but are quieter and more efficient.
-
Smart-ready controls: Integration with Wi-Fi thermostats or zoning adds cost but improves comfort.
-
Build quality and warranty: Top brands like Goodman, Rheem, and King offer 10-year warranties.
“I spent $2,500 on a 20kW Goodman furnace — not the cheapest, but I wanted something efficient and quiet enough for daily use.”
🧰 2. Installation Costs: Labor, Permits & Materials
Even the most affordable furnace can double in cost once installation comes into play.
Most homeowners hire a licensed HVAC installer or electrician, since electric furnaces need a dedicated 240V circuit and a correctly sized breaker.
💵 Typical Installation Breakdown:
| Item | Estimated Cost |
|---|---|
| Labor (HVAC & electrical) | $800–$1,200 |
| Wiring, conduit & breakers | $150–$400 |
| Ductwork modifications | $100–$300 |
| Permit & inspection fees | $75–$200 |
| Total Installation Cost | $1,100–$2,000 |
A full professional installation averages $3,000–$4,000 total when you include equipment, parts, and labor.
“My installer handled the wiring, permits, and safety inspection — and honestly, that peace of mind was worth the labor cost.”

🔌 3. Energy Usage: How to Calculate Monthly Running Costs
Once your furnace is in place, the biggest ongoing cost is electricity.
Here’s the simple formula to estimate your monthly heating bill:
Furnace kW × Hours per Day × $/kWh × 30 Days = Monthly Cost
Example:
Let’s say you have a 15 kW furnace in a 1,600 sq. ft. home.
You run it 4 hours per day at $0.13 per kWh (the U.S. average).
15 × 4 × 0.13 × 30 = $234/month during heating season.
Now, that’s the high side — most furnaces don’t run continuously. With a programmable thermostat and good insulation, you can reduce that by 20–30%.
“After installing a smart thermostat and sealing my ducts, my monthly cost dropped by nearly $60.”

|---|---|---|
| South | $0.11 | $198 |
| Midwest | $0.13 | $234 |
| Northeast | $0.18 | $324 |
| West | $0.15 | $270 |
Homeowners in southern climates often find electric furnaces affordable because they run less often. In cold regions, pairing the furnace with a heat pump can significantly cut running costs.
