At Kova Heating & Cooling, we help Portland and Vancouver homeowners stay warm, safe, and energy-efficient with expert furnace care. If you’ve ever asked yourself, “Is my furnace gas or electric?” — you’re not alone. Knowing what kind of system you have is the first step toward effective maintenance, energy savings, and peace of mind.
Whether you’re preparing for a cold winter or just doing seasonal upkeep, here’s how to easily identify your furnace type and what it means for your home.
What Does a Furnace Actually Do?
Your furnace is the heart of your home’s heating system. It draws in cool air, heats it up, and then circulates the warm air through your ductwork and vents. But how it creates that heat depends entirely on its fuel source — either natural gas or electricity.
How to Tell If Your Furnace is Gas or Electric
If you’re unsure which type you have, here are some simple ways to identify it:
1. Check Your Utility Bills
Do you get a gas bill? If so, you likely have a gas-powered furnace. Electric-only homes won’t show gas charges.
2. Look for a Gas Line
A visible gas pipe or copper line running into the furnace area is a telltale sign of a gas furnace.
3. Find a Gas Meter or Propane Tank
Most homes with gas furnaces have a gas meter outside. Rural homes might rely on a refillable propane tank.
4. Peek Inside the Furnace
Remove the front panel (if safe). If you see a blue flame or burner, it’s gas. If you see only wires and coils, it’s electric.
5. Inspect the Breaker Box
Electric furnaces usually require two breakers, often 20-amp each. A gas furnace usually runs off one smaller breaker.
6. Listen to the Noise
Electric furnaces give off a low hum. Gas furnaces are noisier — you’ll hear ignition clicks or a “whoosh” when the burner kicks in.
Key Differences Between Gas and Electric Furnaces
Electric Furnaces
- Pros: Lower upfront cost, easier installation, no risk of carbon monoxide
- Cons: Higher energy bills, slower to heat
- Best for: Mild Portland & Vancouver winters or homes with limited gas access
Gas Furnaces
- Pros: Quick, powerful heat; lower monthly heating bills
- Cons: More maintenance, safety checks required due to potential gas leaks
- Best for: Colder Portland areas or homes that rely on frequent heating
Maintenance Tips for Both Furnace Types
Whether your furnace is gas or electric, regular maintenance helps avoid breakdowns and keeps it running efficiently.
- Change filters every 1–2 months
- Check for odd smells or sounds
- Schedule annual inspections, especially for gas systems to detect leaks, burner issues, or venting problems
- Clean residue buildup inside gas furnaces that can lead to corrosion
How Long Will My Furnace Last?
- Electric Furnaces: Up to 20 years with proper care
- Gas Furnaces: Around 10–15 years, though maintenance can extend lifespan
