Oil-to-Gas Conversion in Yonkers — Process, Cost & Rebates

Step-by-step guide to converting from oil to natural gas in Yonkers, including Con Edison hookup costs, NYC permits, and 2025 rebate stack.

Published 2025-11-18 · Bravo Mechanical, Westchester County, NY

Yonkers has one of the highest concentrations of remaining oil-heat homes in Westchester — particularly in Bryn Mawr, Park Hill, and Crestwood. Converting to natural gas can cut heating costs by 30–45% and dramatically simplify maintenance. Here's the full process.

Step 1 — Confirm gas is on your street

Most Yonkers streets have gas mains, but not all. Call Con Edison at 1-800-643-1289 or check their service map. If a main needs to be extended, that can add $5,000–$25,000 (sometimes Con Ed covers it for multi-home conversions). > Pricing and incentive availability vary by equipment, home conditions, utility program rules, and current market costs. This guide is for planning only; final pricing requires an on-site assessment.

Step 2 — Get the gas service installed

  • $0–$2,500 for the service line (frequently free for residential conversions)
  • 4–10 weeks lead time
  • Yonkers Building Department permit required

Step 3 — Remove the oil tank

  • Above-ground basement tank: $400–$800 to drain, cut, remove
  • Underground tank: $1,800–$4,500 (with soil testing)
  • Documentation matters — Yonkers buyers/insurers will ask for a closure letter

Step 4 — Install the new gas boiler or furnace

  • High-efficiency gas boiler (95% AFUE): $10,500–$15,500
  • Combi boiler with on-demand hot water: $12,000–$17,000
  • High-efficiency gas furnace + AC ready: $8,500–$13,500

Step 5 — Chimney lining

Almost every Yonkers oil-to-gas conversion needs a stainless steel chimney liner ($1,200–$2,500). Old masonry chimneys can't safely vent low-temperature gas exhaust.

Step 6 — Final inspection and meter set

Yonkers Building Dept inspects, then Con Ed activates the meter. Total project timeline: 6–12 weeks.

2025 rebate stack for Yonkers conversions

  • Con Edison high-efficiency boiler rebate: $400–$1,000
  • NYSEG / Con Ed conversion incentive: up to $1,500
  • Federal 25C tax credit: up to $600
  • NYS Clean Heat (heat pump only): consider going further and switching to a heat pump for $5,000–$10,000

Total realistic Yonkers project cost

$13,500–$22,000 all-in for a typical conversion, $11,000–$19,000 after rebates.
