THINKING ABOUT SWITCHING FROM OIL TO GAS? READ THIS FIRST.
Every time oil prices spike, homeowners start asking the same question: should I just convert to gas? After this season's run-up past $5.60/gallon, that question is louder than ever. Here's the honest breakdown.
WHAT IT ACTUALLY COSTS
A full oil-to-gas conversion runs $6,000 to $20,000 depending on your situation. That includes a new gas furnace or boiler ($3,500-$7,000), oil tank removal ($500-$3,400), gas line connection ($1,000-$2,000+), permits, and labor. If your street doesn't have a gas main, it could cost significantly more — or it might not be possible at all.
THE SAVINGS ARE REAL — BUT SLOW
Natural gas is cheaper per BTU than heating oil. Most homeowners save $800 to $1,500 per year after converting. But at that rate, you're looking at a 5-10 year payback on the conversion cost. When oil is at $5.60/gallon the math looks great. When oil drops back to $3.50, that payback period stretches.
BEFORE YOU CALL A CONTRACTOR, CHECK THREE THINGS
→ Is natural gas even available at your address? Large parts of rural CT, MA, and northern New England don't have gas mains. Call your utility (Eversource, National Grid, etc.) or check their website.
→ How old is your current oil system? If it's under 10 years old and working well, you might be better off riding it out and saving the conversion cost.
→ How long are you staying? If you're selling within 5 years, you probably won't recoup the investment. If you're staying 10+, the math starts working.
WHEN CONVERSION MAKES SENSE
→ Your oil furnace is 15+ years old and needs replacement anyway
→ Gas is available at your address
→ You plan to stay in the home long-term
→ You want to add gas appliances (stove, dryer, water heater)
→ You're tired of oil delivery logistics
WHEN STAYING ON OIL MAKES SENSE
→ Your system is relatively new
→ Gas isn't available or requires an expensive line extension
→ You're not staying in the home long-term
→ You're comfortable shopping around for competitive oil prices
THE BOTTOM LINE
Converting to gas isn't a no-brainer — it's a significant investment that makes sense for some homeowners and not others. Don't let a price spike push you into a $15,000 decision. Run the numbers for your specific situation.
