Is now a good time for you to invest in a new home heating system?

Connecticut residents are bracing for higher winter expenses, with federal projections indicating a 21% increase in heating oil bills. As of October 2026, heating oil prices have climbed above $6 per gallon.

Why it matters

The ongoing U.S.-Iran war has disrupted global energy markets, significantly impacting fuel affordability for Connecticut households. This surge creates a substantial financial strain for the 40 percent of the state that relies on heating oil.

The federal Energy Information Administration projects a 21% increase in winter oil bills compared to the previous winter, a rise expected to exceed $360. This follows October 2026 price averages of over $6 per gallon for home heating oil.
