⚖️ 1. Understand the Pros and Cons of Electric Furnaces
Pros:
-
Lower upfront cost compared to gas/oil systems
-
Easier installation (no flue or gas line needed)
-
Safe: no carbon monoxide risk
-
Quiet and low-maintenance
Cons:
-
Higher operational cost in areas with expensive electricity
-
May not be powerful enough for large homes in cold climates

📐 2. Calculate the Right Furnace Size (BTUs)
Choosing the correct size is critical. A furnace that’s too small will underperform, and one that’s too big will short-cycle, wasting energy and wearing out prematurely.
Here’s a general rule of thumb:
| Home Size (sq ft) | Recommended BTU Output |
|---|---|
| 1,000 | 30,000 – 35,000 |
| 1,500 | 45,000 – 52,000 |
| 2,000 | 60,000 – 70,000 |
| 2,500+ | 75,000 – 100,000+ |
But don’t guess—use a furnace sizing calculator or consult a local HVAC professional to account for insulation, windows, ceiling height, and local climate.

♻️ 3. Check Energy Efficiency (AFUE Ratings)
The Annual Fuel Utilization Efficiency (AFUE) rating tells you how much of the electricity consumed actually turns into heat. Most modern electric furnaces boast near-100% AFUE, meaning minimal energy waste.
For comparison:
-
Electric Furnace: 95–100% AFUE
-
High-efficiency Gas Furnace: 90–98% AFUE
-
Oil Furnace: 80–90% AFUE
Because electric furnaces don’t lose heat through flue gases, they’re inherently more efficient at converting power into heat—though cost-per-kWh still matters.

🛠️ 4. Installation, Maintenance & Brand Reputation
While many electric furnaces can be DIY-installed by skilled homeowners, most local codes require licensed professionals for compliance and warranty validation. Look for brands that offer:
-
Easy wiring access
-
Clear labeling
-
Compatibility with standard ductwork
-
Optional upgrades (like air handlers or heat pumps)
Popular and trusted brands include:
-
Goodman
-
Revolv
-
MRCOOL
-
Winchester
