If your current heating system is getting old, you may be wondering: Is it worth replacing now? In this full guide, Tony walks you through the clear signs it’s time to replace your aging furnace and why a 20 kW electric furnace—like the Goodman MBVK20DP1X00-HKTAD201—may be the right upgrade.
🔧 How Long Should a Furnace Last?
Average lifespan estimates:
| Furnace Type | Expected Lifespan |
|---|---|
| Electric Furnace | 20-30 years |
| Gas Furnace | 15-25 years |
| Heat Pump | 10-15 years |
"Electric furnaces are incredibly durable because they have no burners, igniters, or flues to fail," Tony explains.

📉 Signs Your Old Furnace is Wearing Out
1️⃣ Uneven Heating: Cold spots or rooms not staying warm.
2️⃣ Frequent Repairs: Repair costs rising each year.
3️⃣ Strange Noises: Clanging, squealing, or humming sounds.
4️⃣ Rising Electric Bills: Declining efficiency as parts wear.
5️⃣ Dust & Air Quality Issues: Duct leaks and poor filtration.
6️⃣ Short Cycling: Furnace turns on and off too frequently.
"If you're calling me out more than once or twice a season, it's time to think about a replacement," says Tony.
💸 The Hidden Costs of Keeping an Old Furnace
-
Higher energy bills (10-30% more than new models)
-
Frequent repair visits ($150-$600 per call)
-
Poor indoor air quality affecting health
-
Reduced comfort during extreme cold
"Many homeowners don’t realize how much money they’re bleeding slowly through inefficient equipment," Tony warns.
⚠ Safety Risks with Aging Furnaces
-
Electrical shorts from worn wiring
-
Fire hazards from failing heating elements
-
Duct air leaks creating poor airflow
-
Lack of modern safety shutdown controls
"While electric furnaces are very safe overall, age increases risk. Inspections matter more than ever after 20 years," Tony stresses.

🧮 Cost Comparison: Repair vs. Replacement
| Scenario | Estimated Cost |
| Major Component Replacement (Blower, Heat Elements) | $800 - $2,000 |
| Full Electric Furnace Replacement | $6,000 - $9,000 installed |
"At some point, the repair bill gets close enough to replacement cost that upgrading simply makes better long-term sense," says Tony.
🔋 Environmental Benefits of Upgrading
✅ No fossil fuels burned
✅ Compatible with renewable energy (solar, wind, hydro)
✅ No carbon monoxide or gas leaks possible
✅ Supports long-term electrification goals

🧠 When Should You Upgrade? Tony’s Rule of Thumb:
✅ Furnace older than 20 years
✅ Repair costs exceeding 25% of replacement value
✅ Utility bills have climbed 15-20% vs prior years
✅ Significant home insulation upgrades completed (downsizing possible)
✅ You plan to stay in home another 5+ years
"Upgrading before total failure avoids rushed installs and gives you more control over price and timing," Tony advises.
