Three honest causes: your heating system is inefficient, your house leaks air, or both. The fix stack is the same either way, and the rebate stack is very real.

The rebate stack, the smart play, and why each one matters for this specific problem.
Heating oil runs $3.40-$4.20 per gallon in winter. Natural gas rates climbed again in 2025-2026. Electric resistance heat is the worst of all, at around $0.28/kWh delivered, a single-room electric heater can cost $3-5 per day. A well-tuned heat pump running on the same grid delivers the same heat for a quarter of the cost. The technology exists now. The rebates to install it are at historic highs.
