Four in ten Long Island homes still heat with oil.
Roughly 40 percent of Long Island homes run on heating oil, more than eight times the national average. National Grid offers conversion rebates worth up to $1,100 for switching to natural gas. PSEG Long Island heat pump rebates can stack up to $11,000 for income-eligible customers. NYSERDA Clean Heat adds more on top. The HVAC company that can navigate that rebate stack and rank for 'oil to gas conversion Nassau County' or 'heat pump rebate Suffolk County' is positioned for the largest home energy retrofit in the region's history.
